Parking Garage LED Lighting Retrofit Case Study

LED Retrofit Parking Garage.png 

This parking garage lighting project's dramatic improvement in lighting came along with $23,634 in utility rebate incentives, plus a Green Business Cost Sharing program from the city of Minneapolis when this client upgraded the aging, inefficient high pressure sodium lighting. They now have better light quality in their facility, increased safety for their patrons, and they are saving money and resources at the same time! Keep reading to see more specifics about how Allied Parking upgraded to LED lighting in the MTC facility at their Gateway ramp downtown Minneapolis.

Facility Statistics: The Benefits of a Lighting Upgrade

Common lighting issues in parking garages include dark, shadowy areas and poor light quality. By replacing the existing High Pressure Sodium lighting with energy efficient LED that consume only 45 watts each, this facility is taking advantage of major energy savings. At the end of this project the client was saving 143 watts per fixture, reducing energy usage by 76%!

Cost Savings: Does is really add up?

Before completing this LED lighting retrofit project, TRC performed a full facility audit. This means all of the existing fixtures were counted, along with their rate of energy consumption and hours of operation, and a cost of operating was established. The new, more energy-efficient system was also proposed in the same way. The difference in energy usage totaled $14,430 in annual lighting cost savings. 

Kw and kWh were both reduced by 76% annually with this LED retrofit. The client qualified for $23K in energy-efficiency rebates from their local utility company, and an additional cost sharing program amount was awarded to them by the city of Minneapolis' Green Business Cost Sharing Program

Carbon Savings: What does it mean? 

Based on kWh reduction from our facility lighting audit and using a Greenhouse Gas Equivalencies Calculator, we can determine carbon savings of 110.6 tons of CO2 for this energy efficiency project. This is equivalent to keeping 21.7 cars off the road for a year, 12,395  gallons of gasoline saved, or 38.5 tons of waste recycled instead of land filled!

Lighting Retrofit - Vs - Lighting Redesign

lighting_retrofit_vs_redesign.png

 

As our company approaches its 25th business anniversary, we know this for sure: no two lighting projects are the same. So, when you're presented with several options for a lighting project, how can you know which is the best option for you - lighting retrofit or lighting redesign? In this post, we're going to step through three common approaches to lighting projects and discuss each in detail. First, let's talk a little bit about why all projects are so different.

YOUR BUSINESS IS YOURS. YOU DO WHAT YOU WANT.

You know that your business needs may be similar to another company of your same size in the same industry, but you also know that you've got differing needs. Here are some factors you should consider and questions you should be able to answer as you consider whether or not to upgrade your lighting: 

  • Do you know if you over or under lit?
  • Do specific areas of your process have different lighting needs?  For example, in manufacturing an inspection line and a warehouse/staging area would require different types or amounts of lighting. In an office setting you may have presentation spaces and work spaces where different tasks take place.
  • Are areas of your space unoccupied for long periods of time?  If you are not using any lighting controls currently, this would be a great place to consider implementing a controls system.
  • What does the future of your business look like? Do you have expansion plans or anticipate a change to your layout? 
  • Do you need a lighting system that is capable of growing with you?  By designing with a smart fixture that can do more than what we’ll tell it to do, you can always adjust the light level as your needs change. (This applies to most LED options.)
  • Because each business is different these are just some of the variables that are taken into consideration when planning or designing a lighting system.

WHAT ARE YOUR OPTIONS?

Understanding your business needs is the first step in project planning. Your needs may be simple and direct and your business may not be changing, or you may be a company in the midst of growth and you envision many changes in the future to your business process. Three general options exist; we're calling them "Good," "Better," "Best."

What_are_my_project_options.png

OPTION 1: GOOD 
REPLACE THE LAMPS

This option has a low up-front cost and results in minimal waste. Replacing lamps is generally a quick and simple solution, energy-efficient lamps are relatively easy to find. There is typically a good simple payback with reduction of wattage per lamp. With this simple scope of work, the rebate is also straightforward. In most cases rebates are per lamp, but this depends on the type.

This option will have a shorter over all system life than most fixture replacements; it will result in higher future maintenance costs. Replacing lamps will not necessarily address inconsistent light levels, improve performance, or reduce shadows that currently exist in your lighting. This option is not recommended for rugged or hazardous environments.

OPTION 2: BETTER
REPLACE FIXTURES 1-FOR-1

Nearly half of the projects evaluated will have a one-for-one fixture replacement solution. This solution is pretty likely to result in a successful project, and has been a pretty standard approach in the lighting industry for years. Again, the scope of work is pretty simple, and so is the rebate structure. Rebates are typically per fixture, and removing some fixtures can result in a higher rebate. Replacing fixtures in their existing locations also means a lower up-front cost to this project type because you do not have a cost associated to wiring fixtures to new locations.

With this sort of project, we have seen results where light levels went from 30 to 100 foot-candles in a gymnasium. Without controls, or ability to adjust light levels, a lot of energy is wasted to over-light this space when no events are happening in it. In addition to being over lit, keeping these unneeded fixtures will result in higher costs for energy and higher maintenance costs.

This solution may work just fine for half of projects as we noted, however; the best projects are given more consideration. Redesign planning is where a lighting design professional will outshine a standard electrical contractor.

OPTION 3: BEST 
LIGHTING REDESIGN

Lighting redesign is a collaborative process between a business owner or operator and a lighting professional. The process takes into consideration your business, how it functions, how spaces are used, and any financial and environmental goals that your business has in sight. The solution begins with a study, or deep dive into all these factors, and when research is completed a custom lighting system is designed. Certified lighting professionals work with you to ensure that the scope of the project will meet your needs, and all aspects of it will be planned out in a series of reports before a single piece of equipment is ordered. This is the most sophisticated route for a lighting project, an investment in your investment.

Some utilities offer reimbursement programs to reduce the cost of the investment in a lighting study, which is in addition to the rebate received for energy savings. While a project study may increase the payback time period, the overall results are a lowered long term cost of ownership factoring in maintenance savings and energy reductions. 

Why should you consider a redesign if a one-for-one fixture replacement would be just fine? Once again, this comes down to the level of sophistication that is inherent in LED lighting. There are as many solutions as there are businesses, and sorting through all of those is nearly impossible unless you plan with the help of a lighting partner. You can have a good project, or with a little more insight you can have a great one. Partnership with a great lighting professional will allow you to get the most out of your lighting project investment by starting off with the best plan possible.

Understanding LED Linear T8 tubes

In our previous two blog posts, we discussed LED linear tube options for your LED lighting retrofit. First we gave an introduction and discussed some safety concerns, and then outlined the three types of LED tubes. Keep reading to learn a final set of variables to consider when selecting LED tubes, and next steps to get your project going on the right foot!

Know what you are trying to accomplish when selecting LED tubes

Even when you have the correct combination of linear LED tubes and existing ballast or wiring configuration, simply grabbing an LED tube and installing it may change lighting levels drastically, undoing the original success of a well-designed lighting solution. Safety and compatibility requirements aside, there are two additional primary factors to consider when selecting LED T8 linear lamps to help maintain good lighting design that may already exist in your space. The first is lumen output and the second is the beam angle of the lamp.

When LED tube wattage is too high, the result is an over lit space. This may mean you have more light than you need, and that’s not the end of the world; however, that result means energy is being wasted. You are dismissing potential energy and utility-cost savings. You don’t have the optimum lighting design for your application.
Beam angle is critical. A traditional fluorescent lamp casts light 360 degrees around the linear tube, but T8 LED is available in a range of beam spread from 160 to 325 degrees. Simply put, this beam spread can dramatically affect how a space looks when lit with linear LED. There are specific applications for beam angle, and using the incorrect beam angle could achieve undesired results. For example, a 160-degree beam angle will stripe a fixture and also change the optics of the fixture, once again undoing a well-designed project. A 325-degree beam angle lamp will not "stripe" a fixture and will utilize the optics of the fixture much like a fluorescent bulb.

If you are ready to make a change to energy-efficient LED, and a linear T8 LED seems like the best solution for you, it’s important to understand the variables you will face when confronted with this sizable purchase.

Next Steps for a Successful Lighting Project

  • Look for a neutral vendor, one pushing a single product line or manufacturer should be avoided. Choose someone that can explain the differences between products and price points so you can choose the solution that best fits your needs.

  • Ensure you have partnered with a lighting designer that has seen a variety of these lamps perform. One challenge that we face with this constantly improving technology is that photometric data on the lamps can’t be paired with IES fixture files in some instances.

  • Ask for case studies in industries similar to yours, or ask to see some products in action. It can be very helpful to see these lamps in person.

  • Ask for a test in your space. You may want to hire a reputable lighting partner to install a test area to be sure the results are what you want, and meet your lighting project goals.

  • Consider whether or not you need to increase light levels. Ask whether lighting controls would make sense for your business and lighting project goals. Both of these can impact how much energy a lighting project could save for your organization.

  • Always consult the utility company’s rebate guide to get the system with the most rebate incentive, a higher priced system may result in a lower NET project cost based on rebates. Without understanding these rebate structures, you may be leaving money on the table.

 

Deeply consider how you would like to approach your lighting upgrade investment, are you simply looking for greater energy efficiency, or do you want to improve lighting, reduce maintenance expenses, and step in to the future with a well-designed system? If you would like to know more about the benefits of a lighting retrofit beyond energy savings, we recommend our article outlining 6 other reasons to retrofit beyond money and energy savings.

3 types of linear Led tubes

types-of-linear-LED-tubes.jpg

There are 3 general types of T8 LED tubes used in LED lighting retrofit projects. In this post we evaluate each of these LED linear tube options, sharing best uses, and some pros and cons. If you haven't yet read the previous introduction LED T8 technology, we recommend our post called  "T8 LED LIGHTING RETROFIT INTRODUCTION & SAFETY." Keep reading to learn about the three types and how they can benefit your energy efficient lighting upgrade.

TYPE A LINEAR LED TUBES

Type A Lamps are a fluorescent ballast compatible lamp with exceptions. These exceptions are expansive, in fact almost every manufacturer suggests consulting their list of compatibilities before installing LED T8 tubes. We have found that there are even scenarios where the LED lamp product is not compatible with ballasts from the same manufacturer.

The benefits of this type are that they come in different wattages and beam angles, and lumen output for this type can be controlled by the existing ballast: Low Power (LP), Normal Power (NP), and High Power (HP). Most often, these lamps are installed as a simple “relamp” project, but it is important to consider the age of your ballasts when choosing this type. If you intend to change ballasts the week after you install these LED lamps, that may undermine the goals and objectives of your project. Whether or not type A is going to be the best solution for your project depends greatly on your maintenance story.

TYPE B LINEAR LED TUBES

Type B lamps are a direct wire lamp, the most dangerous of the three. This lamp requires the ballast to be removed and the sockets wired direct to line voltage. This system will also require an un-shunted socket, where terminals on the ballast are wired independently. Even though the fixtures are to be marked as having a direct wired lamp, the potential for an LED ballast or LED driver type lamp being installed is great. This will cause severe problems including lamp failure, sparking, even fires. Because you eliminate the need for a ballast, these lamps are chosen when trying to maximize maintenance savings, but safety must be part of the overall consideration to choose a lamp of this type. We have shared a quick video that demonstrates how easily this fire hazard can occur

TYPE c LINEAR LED TUBES

Type C Lamps are an LED lamp with a fixture mounted driver, the drivers are now available with three different standard outputs as well as programmable for more or less output depending on the light levels required. The Type C lamp is also similar to an LED fixture, as you have a light engine and a separate driver. These lamps aren’t considered nearly as often as they should be. They typically offer the longest life, and dimming capability that the others do not. The reason they’re not chosen as often is due to their higher price point. Total Cost of Owning a lighting system should be evaluated when considering whether these are affordable for your project. The type C lamp has just recently achieved controllability using different Mili-amp Drivers. The drivers are more expensive, but in some instances the will achieve a higher lamp life rating 60,000 versus 50,000 hours.

T8 LED Lighting Retrofit Introduction & Safety

T8-LED-Tubes-Introduction.jpg

Are you considering a lighting upgrade and have you investigated replacing your T8 fluorescent lamps with T8 LED linear tubes for energy efficiency? This is a wonderful leap in the lighting world, affording lighting designers, facility managers, and other contractors the ability to essentially retrofit existing fluorescent fixtures with LED linear tube options. It can be seen to have benefits and cost savings over a major redesign and new lighting system overhaul; however, there are many considerations to be aware of as you begin planning your lighting project if you only intend to replace fluorescent tubes with LED tubes. Unfortunately, it’s never as simple as just changing a light bulb. Keep reading to learn some of the pitfalls and concerns to keep in mind as you learn about LED T8 lamps.

Be careful when selecting LED T8 replacement tubes

True lighting designers design spaces to be illuminated so they meet industry light level standards and the needs of the people who occupy a space allowing them to effectively do their work. After all, the lighting required in a retail setting or a classroom will be dramatically different than what is expected in a manufacturing facility or operating room.

In the days of fluorescent lighting great design was achieved with the correct combination of lamps, ballasts, and reflectors to gain maximum lighting for as little wattage input as possible using photometric design. This meant that these spaces were as energy-efficient as possible while maintaining adequate light levels for the activity taking place in them. Since the advent of LED technology, specifically Linear LED Tubes, many facilities are looking to make the leap into even greater efficiency by replacing their existing fluorescent tubes with linear LED tubes. See some recommended light levels for specific industries and types of tasks here.

Without replacing the fixtures, linear LED lamps allow facilities to effectively retrofit their fluorescent technology to something more efficient with relative ease. Sounds simple enough, right? Well, unfortunately there are many variables among the available LED tube products and selecting the wrong one to update your existing fixture could lead to a poor outcome ranging from being over lit or ruining your existing lighting design, to dramatic malfunctions that end up being an outright dangerous fire hazard.

In our next Linear T8 LED blog post, we will discuss three types of LED tubes, the scenarios where you might find them, and the potential outcome of incorrect energy efficient lighting retrofit procedure. While we know this technology to be effective, safe, energy-efficient, and that it looks great when properly installed, it is most definitely not a one-size-fits-all solution.

Pros and Cons of T8 LED REPLACEMENTS (Links)

T8-LED-Replacement-lamps.jpg

A couple weeks ago we shared a video showing how a T8 LED replacement bulb can catch fire if it is incorrectly installed. Because we have committed to being a vendor neutral company we thought a good approach to understanding this technology, and to help guide your decision making, would be to provide the perspective from many different angles, including a look at how things have changed since the onset of this technology. Here's a link round up of some of the best articles we could find.

"Many believe that the LED tube industry has not matured to a trustworthy level, but manufacturers have improved thermal management, and installations now range from Fortune 100 companies to leading health care institutions to leading higher-education institutions." Read more

This article was published a couple years ago, but "8 Reasons To Consider LED Replacement Bulbs..." still holds strong. Efficiencies, realiability, and product selection have only improved in that time!


When you're ready to make the change, we recommend working with a lighting design professional; however, you may still be interested in how to chooseT12 and T8 LED replacements. EarthLED covers five important considerations in this article.

What are the other benefits of upgraded lighting?

six-other-reasons-to-retrofit.jpg

Since starting this blog, The Retrofit Companies has worked to share our lighting retrofit case studies and stories about lighting retrofit projects that address a range of topics beyond energy-savings and efficiency. However, we know your time is valuable, and you probably don't have an hour or two to find each one and read them all. So, this post summarizes a few topics that are very relevant in today's lighting project landscape. Each of these projects started saving money and energy as soon as the project was completed, but they also address other project goals. Keep reading to see six lighting design and retrofit projects that summarize a few priorities, aside from efficiency and financial savings, that clients have brought to us when we discussed their project goals.

1 FUNCTION: "We need a lighting system that just works better."

It doesn't happen all the time, but sometimes clients come to us looking for a lighting solution to make their lighting system work better for them, overall. In this case study, the facility needed a sustainable, controllable, maintenance-saving lighting system. The existing system in their large production area was all on or all off, no controllability at all. It was also using outdated T12 fluorescent technology. The solution was a combo T8 and LED design with dimming and sensors on the control system. CLICK TO READ THE ARTICLE

2 ONE PIECE AT A TIME: "It's better for us if we don't retrofit EVERYTHING NOW."

Sometimes, a client doesn't have the budget to do an entire project all at once, but they know that a strategic plan of attack can still have dramatic results. When clients decide to address major areas of concern first, or because their budgets necessitate it, they simply do several smaller projects over time. Whether the project is exterior parking lot lights, a gymnasium, or simply common areas like hallways, every reduction in usage can help. This case study shows how one school converted T8 fixtures to a slimmer, lower maintenance cost LED fixture to achieve better aesthetics, more energy savings, and reduced maintenance expenses. CLICK TO READ THE ARTICLE

3 RELIABLE DESIGN: A CAUTIONARY TALE FOR THOSE COMPARING "SIMILAR" proposals

This one is a little more difficult to summarize in under a hundred words, so if this applies to you we recommend clicking through, and also downloading the ebook about investment grade audits. Here's the 10,000 foot view: a lighting redesign project was put together, but one digit in a part number was off, and the project came out a failure. Using the SAME fixture, with correct optics a second time, yielded positive results. Now imagine if this were your project and you were in a position to compare multiple fixtures, from multiple vendors. How could you be sure you're getting the results you want and need? CLICK TO READ THE ARTICLE

4 WE ARE EFFICIENT: "We already have T8 fixtures, why upgrade?"

Not every project results in dramatically improved lighting, and impressive before and after photos. You may even have a relatively efficient T8 fluorescent system in place now; however, improvements in LED and controls systems can yield impressive results in other ways. In this warehouse's energy efficient redesign project, the customer reduced the number of fixtures in use, decreased maintenance, improved controls with sensors, and of course, they are saving almost $5k in annual lighting costs. CLICK TO READ THE ARTICLE

5 SAFETY, MAINTENANCE & AESTHETICS: Thoughtful design results keep on giving!

Here a client came to us with an idea in mind, he even had a fixture chosen and several goals to achieve. Read this one to see how a custom design improved energy-efficiency AND improved the look of the fixtures, reduced maintenance expenses, and improved safety on site. Remember that great planning and utilizing the correct LED optics in your new design vs simply retrofitting one-for-one with an efficient fixture can bring your project to the next level and meet a range of goals! CLICK TO READ THE ARTICLE

6 SOLUTION FOR MULtIPLE LOCATIONS: Again with the importance of planning? Yes.

This last one has some really impressive before & after photos, but the importance of noting this is to showcase one last time how planning ahead will yield the best results. We interview a client about their decision to beta test a solution for multiple locations nationwide, and hear from the lighting rep on the project about some aspects of planning. CLICK TO READ THE ARTICLE

Did you know that commercial lighting rebates and incentives are available from most utility companies? In this blog post we highlight the Alliant Energy lighting rebate Commercial Lighting Program – it's one of the largest utility providers in the state of Iowa. Keep reading for more insight.

We have been fortunate to work with clients throughout the United States to become more energy efficient by providing smart lighting upgrades. Many of the projects we work on also allow clients to take advantage of rebate programs offered by their local utility providers. For more information about incentive programs, you can read a previous article here that answers questions such as, "how do I get a lighting rebate?" and "why do utilities offer rebates?"

Here are the commercial lighting rebate categories currently offered by Alliant Energy*:

• Small Business Energy Solutions. Turnkey lighting solution exclusively for small business that includes design and installation. Alliant Energy pays up to 75% of the total project cost.

• Compact Fluorescent Bulbs. Think of how many bulbs are in your office, break-room and even storage area. If any of those are incandescent bulbs, switch to CFLs.

• LED Bulbs & Fixtures. LED bulbs last two to five times longer than CFLs and 35 to 50 times longer than incandescent lighting.

• LED Replacements. Increases in efficiency and lower prices make LEDs an attractive choice for replacing linear fluorescent fixtures.

• Lighting Controls. By adding lighting controls to your facility you increase the flexibility of your lighting plan.

• Fluorescent, High Bay, HID, Delamping. Fluorescent tube lighting is a great way to light up large spaces, plus energy-efficient T8 lamps are up to 40% more efficient than T12 lamps.

• Pin-type Compact Fluorescent Fixtures. The pin-type compact fluorescent fixtures have all the efficiency of the standard CFL fixtures and result in savings on your utility bill.

• Replacement LED traffic lights. LED traffic lights use approximately 90% less energy than incandescent lights and because they last so long, maintenance costs are reduced by 75%.***

The rebates listed above are currently being offered in 2015, and the year end is approaching fast. However, if you haven’t taken advantage of these incentives this year and you’re making plans to do a lighting upgrade in 2016, there’s good news – most programs (especially those that have been successful during the previous year) usually continue into the following year, and often even with higher incentives!

Function Over Finance: Lighting Project Priorities Are Shifting

function-over-finance

The Retrofit Companies has been in the lighting industry for more than 20 years, and we have witnessed many changes in technology, trends, and the goals our clients wish to achieve through their lighting projects. The most recent trend has been a shift away from the idea that clients buy lighting projects based only on energy savings needed to achieve financial savings. Payback and return on investment have become less important in modern lighting upgrade projects, while building sustainable, controllable, maintenance-saving lighting systems have become factors which weigh just as heavily in the decision making process as finances. 

Technological advances in lighting is a primary reason for this shift. The malleable nature of LED technology and the ease with which controllability can be achieved now that prices for both of these technologies are attainable throughout the market has made the largest impact. Lighting designers and clients can now affordably meet their goals of building sustainable, controllable, maintenance-saving lighting systems.

In this project case study a smaller business with a large industrial/manufacturing space suffered from inefficient technology and almost no controllability. The largest area of this space was lit with T12 and metal halide and had no control function aside from a single breaker switch – all on or all off.

Before-Retrofit-T12-Lamps

With their retrofit project, this facility upgraded technologies to T8 and LED, and added sensors for additional control. They were able to meet their maintenance, sustainability, and controlability goals successfully.

after-retrofit-led-t8-lamps

In this case, the simple payback is over 8 years, but the monthly energy savings is an anticipated $200+ for this small business and they are able to light only areas that are being used. This savings does not include maintenance savings for the inevitable expense of repairing an aging system and purchasing the discontinued T12 products required to keep it in working order if they had not completed this lighting upgrade.

PROJECT GOALS & SUCCESSES

  • Inefficient T12 fixtures retired & recycled
  • 40 unnecessary fixtures removed from use!
  • New lighting layout for maximum efficiency
  • Decreased kWh 69% overall
  • Project rebate $2,213
  • Annual savings over $2829 / nearly $235 a month!
  • New system offers sensors and upgraded controls
  • Cut maintenance costs, new fixtures have 5 yr warranty!
  • New fixtures contain no mercury

EQUIPMENT FACTS

  • Sustainable, Energy Saving LED
  • Rated 50K hours, L70
  • Dimming
  • Even Light Distribution, >80CRI 

ENVIRONMENTAL IMPACT

CARBON SAVINGS
Total greenhouse gas reduction Metric Tons equivalent to: 27.3

  • Passenger cars not driven for one year 5.3
  • Gallons of gasoline saved 3,057.4
  • Acres of forest preserved from deforestation 0.27 
  • Tons of waste recycled vs. land filled 9.5


With this example, we can see a how this approach to building lighting projects that save more than money-via-energy-savings is an evolution in our industry and is an approach that can be applied to lighting projects in most industries. However, the environmental and financial savings are still significant, as evidenced in the project summary above. We advise anyone considering a lighting project or upgrade to look beyond the financial savings potential and also consider other intangible savings opportunities that arise when smart design is implemented.

What does it mean to be "Vendor Neutral?"

lighting-vendor-neutral

 

Vendor neutrality is a concept that might not be top-of-mind, but is something to consider when you're in the thick of planning any large project. It's especially important to be mindful of this when you are presented with equipment or product options from multiple manufacturers and multiple vendors that you need to compare to make a smart purchase. So, what are the characteristics and benefits of vendor neutrality?

The primary benefit of a vendor that is product or manufacturer neutral is that they are able to use the technology best suited to your needs at any time. They are not limited by a specific product provider or set brands in order to shoehorn a solution into your lighting retrofit project. As a result of this latitude, you, the consumer are engaged in business with a firm that is adaptable, well-rounded, and that has flexibility across the almost limitless lighting scenarios that can exist.The requirements of your energy-efficiency project may be completely unique in the world and working with a company that isn't restricted by agreements to only buy from specific product manufacturers is a tremendous benefit to you. Steve mentions this in a previous blog about the history of retrofitting. This isn't a new idea, certainly, but it is important to remember even today.

TRC Sales and Marketing VP, Wendy Fry shares her insight, telling us how vendor neutrality applies to energy-efficient lighting projects,

"Comparing Apples to Apples has just gotten extremely difficult. Gone are the days where a 6-lamp T8 High Bay could be swapped out with 1 of thousands of other options and considered 'the same.' With the creation of LED fixtures, optics and design have given buyers a need to bid specific products built to perform in their environment. If you’re choosing between two projects with '50-watt LED Wall Pack as the only comparison factor, you might be really disappointed in the results of said project.

When considering a purchase from a supplier carrying a few select lines of fixtures, you’re bound to get saddled-up with whatever fixture is the closest match to your needs…that they sell. When choosing a partner in lighting, go with an accredited designer. Then, make sure they are free to choose the solution that will best fit your application. When considering LED, plan to get involved and choose an expert that isn’t bound by what’s on the shelf in a warehouse. Customize."  

When you are planning your lighting system, be sure to ask any electrical contractor you consider working with if they have any product or manufacturer limitations. For our guide on other questions you should ask, download our paper, "11 Questions to Ask a Lighting Contractor."

Why Invest in a Lighting Audit?

Energy-efficiency is a direct path to savings and makes a positive impact to the bottom line for many businesses, but you may be wondering "What's the point in investing in a lighting study," or investment grade audit? We believe there is a singular and simple reason why an Investment Grade Audit is the best way to help prepare for your lighting project investment.

Whether you purchase your study from TRC, another energy service company, electrical contractor, retrofitter, engineer, or architect, our theory is really simple: You shouldn't have to become a lighting expert to expertly buy a complicated lighting project.

More often than not, you want to invest in a lighting upgrade because it makes sense for your business to do so. However, you may not have considered why an investment grade lighting study is the best way to begin. It's the first decision you can make that will allow every consecutive decision to take off in the right direction and result in a successful lighting project.

With an investment grade audit you have an RFP you can submit to several vendors. Inviting several firms in to your business to bid the work you want done will inevitably result in an equal number of very different bids left for you to compare. An Investment Grade Audit arms you with a standardized bid document where fixture counts, operating hours, equipment specs, and every other possible project variable -aside from vendor- are the same, making your job slightly easier. With all the "lighting expert" variables accounted for and all the critical data already collected, you can be sure the project proposals provided by multiple vendors allows you to compare "Apples to Apples."

Your job at that point is to choose a vendor based on price, reliability, availability, experience, corporate buying preferences, or whatever credentials make the most sense for your business. Investing in a lighting study means you've taken the first step toward due diligence. You have reduced the likelihood that you could have been presented with a good looking project based on sub-par data.

To help you in decision making when trying to choose the right partner for your investment grade audit, here are the categories of reports included in an Investment Grade Audit from The Retrofit Companies: 

  • In-depth details on your existing lighting system
  • Existing energy cost benchmarking
  • In-depth details on the proposed (new) lighting system
  • Proposed system operating costs & annual savings
  • Line by line cost-benefit analysis
  • Operational and Maintenance savings comparisons
  • Fixture cut sheets for proposed equipment
  • Photometric layouts for existing and proposed
  • Rebate studies & submittal forms

Case Study: Hallway Lighting Retrofit

led hallway retrofit case study

Not every lighting retrofit project we do takes on an entire facility all at once. Sometimes, clients decide to address major areas of concern first, or because their budgets necessitate it, they simply do several smaller projects over time. Whether the project is exterior parking lot lights, a gymnasium, or simply common areas like hallways, every reduction in usage can help. This case study shows how one school converted T8 fixtures to a slimmer, lower maintenance cost LED fixture to achieve better aesthetics, more energy savings, and reduced maintenance.

Deciding to take control of their maintenance costs by upgrading their hallways was a pretty simple decision for this school. An area with aging fixtures and astronomical replacement costs was a great target to start saving. The major problem? Fixture lenses were brittle, easily broken, and no longer manufactured meaning they cost a ton to replace.

Projects like this prove you don’t have to bite off more than you can chew by retrofitting your entire facility at once. Selecting high-traffic corridors with high maintenance costs or long burn hours can make a significant savings impact. Take a look how this institution is using LED updates to control costs, mitigate maintenance expenses, AND save energy! Their new fixtures are even network ready if the building moves toward a facility-wide control system.

PROJECT GOALS & SUCCESSES

  • Inefficient T8 fixtures retired & recycled
  • 114 unnecessary fixtures removed from use!
  • New lighting layout for maximum efficiency
  • Decreased kW& kWh by 60% overall
  • Project rebate over $1700
  • Annual savings over $1100 / nearly $100 a month!
  • New system connects to building controls
  • Cut maintenace costs, new fixtures have 5 yr warranty!
  • New fixtures contain no hazardous materials

EQUIPMENT FACTS

  • Sustainable, Energy Saving LED
  • 2 inch fixture profile
  • Rated 100K hours, L70
  • Dimming and Network ready
  • Even Light Distribution, >80CRI

9 Signs You Should Invest in LED Lighting

signs you should invest in led

Deciding to invest in energy-efficiency is a decision that every company or business must come by on their own. Oftentimes, an investment in energy-efficiency will yield more than a return on investment. Let’s look at 9 signs that could be telling you it’s time to consider investing in LED Lighting:

 

1) You pay too much in utility costs every month. We have said it over and over, but cutting the watts you use can cut the amount it costs you to light your facility. This being said, your utility bill will always reflect your usage and if you start saving energy today by updating your lighting system you’ll be saving already when utility costs inevitably rise.

 

2) Your business is looking for instant ways to reduce overhead. It’s not quite as simple as flipping a switch, you have to plan your project, but every day after that when you turn on the lights and get to work you’ll be saving energy!

 

3) Your maintenance budget is out of whack. Does your facility have dozens of different bulb-types throughout? Do you have parking lot, auditorium, or atrium areas that are difficult to reach without a lift, increasing your maintenance spending every time one lamp needs to be replaced? Maybe your maintenance staff spends an inordinate amount of time attending to burned out lamps or failing ballasts. You can streamline the products used in your facility, schedule regular re-lamps, and dramatically improve your maintenance budget with a lighting upgrade.

 

4) If you’re honest, your lighting looks ugly or outdated. Mis-matched bulbs in the same room, or fixture, making those handful of yellowish lights look bad when the rest are bright white. Maybe your parking lot or exterior lighting uses high pressure sodium lamps. Those are the lamps that give off orangish light. Both of these scenarios mean you could be more efficient.

 

5) Someone from a lighting/electrical/utility company stopped by and said they could save you money. These statements aren’t always a scam, and sometimes a simple visual inspection by a lighting professional can let them know you have room to improve, efficiency-wise. Not sure how to tell what’s-what? You can read our guide: “11 Questions to Ask an Electrical Contractor” and be sure you're asking all the right questions!

 

6) Your local utility company is offering a rebate for LED lighting upgrades. The utility company wants you to save energy. No kidding. This blog post touches on some of the reasons: http://blog.retrofitcompanies.com/blog/bid/367133/How-do-I-get-a-rebate-for-my-lighting-project

 

7) You don’t want to touch your lighting system again for 10 years. We’re not saying you’ll absolutely never have to touch your lighting system, and we’re not saying it’s 100% maintenance-free, but we ARE saying that a lot of quality LED products – bulbs and fixtures – are coming to market with warranties of five or even 10 years. That says something about the anticipated longevity of these products. How much would you save if you didn’t have to replace a bulb or fixture for 5 years or longer?

 

8) Your business process changes frequently and you need a nimble system. Are you a property manager with a lot of turn-over, or a manufacturing facility that has to re-organize your space with some frequency? Good lighting design can promote job safety and help reduce inefficiencies in your production. And property managers, quality lighting design and efficiency can help you lease your spaces and keep tenants longer.

 

9) You’re building a new facility. This is a perfect time to evaluate your business needs and consider investing in energy-efficiency from the top down. Lighting can be a simple and cost effective way to trim your environmental impact, and ‘going LED’ might be the solution that makes the most sense for you and your business by keeping your overhead costs lower from the start.

You've Identified Some Efficiency Deficits - Now What?

energy deficits in lighting

You've identified some efficiency deficits in your lighting system when you completed the "Common Lighting Problems" checklist. Now what solutions are available to you? Let's review some of the common ways your energy-efficiency is being compromised and a few steps you can take to fix the problem.

Problem 1: Your Lighting Technology is Behind the Times

Whether you have discontinued T12 lamps operating in your facility, are using incandescent lamps, or you notice many different colors of light when looking up at the lights overhead, there is a good chance your lighting technology is behind the times. This aging technology is almost certainly costing you more money than it needs to.

Consider addressing the biggest offenders in your facility first by finding areas that waste the most energy:

+ Do you have any affected areas that operate 24/7 or that are on a majority of the time? These are prime retrofit targets. Upgrading outdated, inefficient lighting that is always on can make a definite impact on your bottom line.

+ Look for areas that are easy to retrofit like any accessible area with inefficient screw-in lamps. Replacing incandescents with LED's, or even CFL's can make a dramatic reduction when done en masse.

+ Do you have strange, mis-matched colors of lighting in your facility? This is commonly seen in HID applications like the orange-hued sodium lights common in parking ramps or metal halide lamps in warehouses and gymnasiums. Aside from being energy hogs and taking a long time to fire up, these lamps degrade over time giving less light, but still using their maximum amount of energy. Replacing them is a no-brainer and many utility companies will offer rebates when you install energy-saving solutions instead.

Problem 2: Things Aren't Working Correctly

It seems like something is always slightly wrong with your lighting. Maybe lights stay on when they don't need to be, your lamps are flickering, or they warm up slowly before coming on to full brightness. These are signals that you could be saving more energy with better lighting and cutting your maintenance costs. Not to mention, your facility is going to look a lot nicer without burned out or flickering lamps. 

Solutions here are three-fold:

+ If your lights are on when they don't need to be, you have serious savings potential. There's more to this than just turning lights off when not in use. There are many ways to reduce light output and energy consumption that makes sense for the way you work. Some easy solutions for you to save could be daylight harvesting, occupancy sensors, or high-end tuning.

+ Flickering lamps can be caused by a few things, the simplest fix is just to be sure that the lamp is firmly in place. A loose connection can cause flickering. On a more serious note, you may be seeing flickering as a result of voltage fluctuation. This can cause lamps to burn more or less brightly than intended, and can cause more frequent burn-outs. If you suspect this issue, contact an electrician.

+ We mentioned earlier that lamps that warm up slowly to full brightness could be HID lamps, or they could be some older CFL technology. Either way, more efficient lighting options exist today and you don't have to spend time waiting around for quality light. 

Problem 3: Maintenance is a Real Hassle

Replacing lamps and ballasts or repairing a failing lighting system seems like it's become a full time job for you, or for the maintenance crew at your facility. Perhaps you have a bulb or two that failed ages ago and still haven't been replaced because they are so difficult to access. This includes areas with very high ceilings, outdoor fixtures, exterior signage, auditoriums, churches and other environments where specialty equipment - more than a ladder - might be needed to change a lamp. 

Let's look at some immediate benefits that a lighting upgrade can have on these situations:

+ If you are frequently replacing many lamps and ballasts and maintenance is a regular routine, it might benefit you to consider a group relamp. When lamps are all replaced at one time and you have a good idea of their usage and  the next group relamp date can be easily calculated. Changing all the lamps at once, at the end of their useful life, for example three years after a lighting retrofit, can again dramatically decrease the regular maintenance costs associated with reactionary spot relamping, or replacing lamps as they fail.

+ If the lamps you are replacing are hard to reach, consider using lighting technology with a very long life. For example, did you know that LED lamp life for certain applications is as great as 100,000 hours? That's more than 11 years of diminished maintenance costs! Another quick LED fact is that they work great in cold environments. Imagine how nice it would be not to have to be outside in the winter performing maintenance on your failing exterior lights.

These are just a few ways you can begin so compensate for energy deficits and work toward a more efficient lighting system in your facility. Have you already completed any of these projects? Tell us about them.

Lighting Before and After // Manufacturing Facility

Northern Iron & Machine, a state-of-the-art manufacturing, casting, machining, and finishing company located on St. Paul, Minnesota’s east side, is updating the inefficient lighting in their 107 year old facility this year with The Retrofit Companies [TRC] as their lighting expert.

Due to the nature of their business, Northern Iron & Machine required a fixture that would handle a more than 100 degree Fahrenheit ambient temperature. They wanted to redesign their lighting system with a long-term solution for optimum efficiency and minimal maintenance. The Electrical Maintenance Supervisor at Northern Iron, Tom Zarnke, had spent several years testing many lighting technologies and fixture configurations on his own, looking for the perfect lighting solution. He thought he had it until TRC lighting specialist, Allison Akre, presented him with an LED solution that met all of the project requirements, and included integrated lighting controls.

hid low bay fixture retrofit


LED Aisle Retrofit

LED LOW BAY AISLE RETROFIT

In these low bay areas, the facility had inconsistent color temperature and shadows as seen in the before photo above. Traditional T8 or T5 vapor tight fixtures would suffer in the facility's 100-degree environment, and open fixtures would get dirty too quickly, requiring too much maintenance.

In the after photo, shadows are lessened, the color of the lighting is consistent, and the new LED vapor tight fixtures stay clean, cool, and consume just 50 watts each.


400 Watt Metal Halide Retrofit


LED HIGH BAY RETROFIT

 

LED HIGH BAY RETROFIT

In these high bay areas, the facility had 30-plus-year-old HID fixtures. Many were severely degraded, giving minimal light while other were completely failed and gave no light. These HID fixtures also consumed 454 watts per fixture. The new LED fixtures in the After photo offer integrated controls, daylight sensors for daylight harvesting, dimming capabilities, and they consume just 190 watts each.

LED RETROFIT CONCLUSION

  • The project is estimated to be complete by mid-April 2014.
  • Projected kWh reduction is 79%
  • kW savings 70%
  • The new lighting solution will save nearly 80% in utility costs annually

With TRC’s design capabilities, Akre was able to secure $12,500 in study fee reimbursement from Xcel Energy. That reimbursement, in conjunction with the project rebate of $31,000 (also from Xcel Energy) means Northern Iron & Machine qualified for a total of $43,500 in incentives.

How Much Does A Retrofit Cost? Part 4

retrofit cost part 4

In our last blog post "How Much Does A Retrofit Cost? Part 3" we discussed five points like Sustainability, Environmental, Financial and Business goals concerning your specific business objectives.

Today's article discusses various topics that can impact the final price of your lighting retrofit project.

FACTOR 4: OTHER PROJECT VARIABLES

Your facility, your existing lighting system, your needs, and your project goals are all factors in the cost of a lighting retrofit; a few more tangible factors also come into play. Our best advice to anyone comparing multiple lighting project quotes from multiple vendors is to be sure you are comparing apples to apples, in all aspects of the project: Service, Product and Extras. Here are the most easily identifiable variables you should be aware of when you consider the cost of a lighting retrofit or upgrade.

What products are to be installed? Which brands of lamps, ballasts and fixtures are being used in your project? Are the names national brands or a fly-by-night manufacturer using untested, sub-par materials? Be sure you understand the quality of the products you are buying, the warranty that is issued with them and that they are fully tested for dependability and safety. Additionally, if your lighting application is very specific or rare (explosion proof, underwater, etc.) the fixtures required will likely be more expensive. Some lighting types lend themselves to energy-efficient, cost-conscious options, but highly specialized products are an exception.  Keep in mind that quality, tested products from respected brands will likely cost a premium, but an experienced lighting contractor will also know that those products work reliably and that is why they spec them.

What Lighting Technology is being used for your retrofit or upgrade? Some types might include: Fluorescent T8, Fluorescent T5, LED, Induction, or others. Be aware that the type of lighting you choose, or require, can profoundly impact the success and the cost of your lighting project. Newer technology like LED is more expensive and more efficient, generally, than older technologies like linear fluorescents like T8 or T5 lamps. Some of the newest LED technology may not be as tried and market tested as linear fluorescent or induction technology, but based on your needs and goals, your lighting contractor will find a solution to make your project a success. (Also note that LED third party testing entities exist to protect consumers, and offer certifications on qualifying LED products that pass their tests for lamp life, performance and efficiency.)

What is the location and length of your project? These are both labor factors to take into account for your lighting project. Will the electricians doing the work have to travel to you? If so, there is a chance your project price includes drive time, per diem and lodging expenses.

Recycling Costs (have they been included in your quote?)  All of the items that are taken out of your existing lighting system should be responsibly disposed of after the completion of your job. These items include: universal waste lamps, ballasts, fixture housings, wiring, packaging, transportation to the recycling facility and actual recycling fees. (learn more about Universal Waste Recycling [link to other blog post])

Are you paying an engineer or lighting designer for a Lighting Study? Every quality project needs to be designed, more or less, from the ground up by taking an inventory (auditing) the existing lighting system, along with hours of operation and utility costs and calculating those factors against a proposed, new, energy-efficient lighting system based on your needs and goals. Depending on the size of your facility and how intricate your system is, this study can cost thousands of dollars. Be sure you are spending your money wisely. If you are hiring an engineer or architect to build this study, there is a chance your one-time fee will be sizeable and non-reimbursable. If you hire a lighting company to do this study, find out if this fee is reimbursable. Ask if the cost of the study will be applied to the total cost of your lighting project, if the project is signed with the firm that completes your lighting study. Knowing this information before you engage in a lighting project is crucial. Understanding this single, powerful point could save you thousands of dollars.

Rebates & Incentives for your lighting project (Are you getting a utility rebate for your project?) Finally, one of the most exciting aspects of any lighting project is the potential for utility rebates or incentives. These funds, commonly provided through money contributed to a utility’s Conservation Improvement Program by fees on every monthly utility invoice, are re-distributed as incentives for individuals and businesses that invest in energy-efficient or energy saving equipment. Essentially, utility companies want to reward smart energy consumers that make steps to improve efficiencies. Lighting project incentives are usually based on watts saved by replacing your existing lighting system with a new, energy-efficient one. Two kinds of rebates exist: Prescriptive and Custom. Prescriptive rebate amounts are based on pre-determined scenarios. [Replace Existing Fixture A with New Fixture Y and you will receive X dollars rebate].  Custom Rebates are just that, custom. Often lighting designers will submit retrofit project plans, with watts saved, to the utility company and try to achieve a greater rebate. This method is also used for facilities and lighting types that may not be exceedingly common. All utilities require a fair amount of paperwork and documentation to issue these rebates. The amount available in rebate funds is usually maxed out each year, so applying early for your project dollars is important. Additionally, most utilities max out individual rebate amounts at a certain percentage of total project cost.  In a nutshell: Rebate dollars are limited, You must submit proper Prescriptive or Custom rebate paperwork to achieve maximum savings, and you must provide appropriate documentation to have money issued to your project. A reputable lighting contractor is able to assist their clients with all of these items, and many times you only need to provide them with a couple of your previous utility invoices and access to your facility for a lighting study so they can get started.

How Much Does a Retrofit Cost? Part 3

what does a retrofit cost part 3

In our last blog post "How Much Does a Retrofit Cost? Part 2" we discussed the second cost factor in a lighting retrofit project: Your Existing Lighting System and Operational Requirements. The variables here include the condition of your current fixtures, the quality of light you experience now, future upgrade plans other then retrofitting your lighting system.

Today's article discusses five major points of cost factor #3 that can impact the final price of your lighting retrofit project.

FACTOR 3: YOUR GOALS

Your goals should be the project priority, whether you were approached by a lighting consultant, were given a directive to do a lighting project from up the ladder, or researched energy-efficiency and learned that upgraded lighting can be a simple, immediate way to reduce operating costs and have a positive environmental impact. If your scenario is similar to these, or something completely different, you have goals in mind for a successful lighting project. We will discuss come common goals that our customers have looked to achieve by implementing energy-efficient lighting. Each is an important factor in the success of a lighting project. Consider which are most important to you.

Are you looking to make an investment in your facility? Property management companies or building owners can increase the value of their buildings, potentially increasing lease revenues, by improving the facility’s lighting system.

Do you have to meet corporate Sustainability or Environmental Goals? An obvious byproduct of using less energy is the preservation of natural resources (coal, oil, etc.) that are used to create electricity. One way to reduce the amount of energy your facility uses is to reduce the overall wattage of its lighting system.

Are you financial goals long term or short term? Consider whether ROI or Payback data make the most sense for how your company does business. A reputable lighting contractor should be able to show you how your project makes financial sense for you.

The US Small Business Administration says, “Depending on the type of business you operate, lighting accounts for 20% to 50% of electricity consumption. This means that significant cost savings can be achieved with energy-efficiency improvements, and due to continually improving equipment, lighting usually provides the highest return-on-investment of major upgrades”

Maintenance savings can reduce the overall perceived cost of a lighting project, especially for large buildings without a full time maintenance staff that must hire out all the work to a maintenance firm. If your building has high cost maintenance areas that require special lifts or scaffolding to reach, or if changing bulbs is a full time job, many lighting contractors should be able to account for those expenses before a lighting project and subsequent savings upon completion of an energy-efficient, long life lighting system.

Achieving reduced overhead (lowered monthly, ongoing utility expenses) through energy savings is a primary goal for many lighting projects. The actual kilowatt or kilowatt hour savings, including savings achieved by employing control systems like sensors, day lighting, dimming, time clocks, and more will be crucial information included on any project quote you receive. Whether or not reduced overhead is your primary goal, it is a major benefit of upgrading your lighting system.  These savings could help off-set the cost of the project, as well. 

You cannot escape the cost of lighting, it is an unavoidable expense of operating your business so consider if you can afford to remain inefficient. With future utility cost projections showing increasing prices, look for ways to minimize the impact of this expensive overhead cost. Specifically, imagine cutting your utility bill now AND paying less-than-you-would-be later. Can you afford to remain inefficient?

Check back next Monday for part 4 which discusses remaining cost factors that can impact the cost of your lighting project.

How Much Does A Retrofit Cost? Part 2

What is the cost of a lighting project


In our last blog post "How Much Does a Retrofit Cost? Part 1" we discussed the first cost factor in a lighting retrofit project: Your Facility. Factors of your facility that influence the price of a lighting project include: the size of your facility, the current electrical service installed, hours of operation or occupation, and general accessibility to the existing lighting system.

Today's article discusses the three important points of cost factor #2 that can impact the final price of your lighting retrofit project.

FACTOR 2: YOUR LIGHTING SYSTEM & OPERATIONAL REQUIREMENTS

The second factor in building your new lighting system is your existing lighting system and your operational requirements. What does this mean? Let’s go through the three main points about your current lighting system that can impact the cost of a lighting retrofit. You will see how the condition of your current fixtures, the amount of light you want and your future business processes can impact the cost of your lighting project.

What is the condition of your current light fixtures? Will you retrofit them (replace only lamps and ballasts, while keeping the same light fixture in place) or will you replace the entire fixture for a complete upgrade? Maybe your building is relatively new, or maybe it’s an historical setting that needs to be preserved. Perhaps the fixture is outdated, dirty, and worn, or the technology you are upgrading to requires a new style of fixture. These scenarios begin to address part of the decision between Retrofitting and Upgrading. So, consider the condition of your existing lighting fixtures at the start of a lighting project to determine if your costs will fall into the retrofit or complete upgrade category. 

Does your current lighting system give you enough quality light for the tasks at hand? How much light do you need? Are you over-lighting or under-lighting for your application? Industry standards exist for recommended amount of foot candles for all types of specific lighting applications, ranging from surgical suites to parking ramps. For example, you may not need ten foot candles of light in your parking ramp, when the specified range is 1-5 foot candles based on the application. Keep in mind that you may not need more light; you may need a better quality of light.

In the near future, are you planning to upgrade, remodel or change processes in the space you plan to do your retrofit? Upgrading your lighting fixtures could be a complete waste if in the near future your facility will be going through a complete overhaul. Perhaps a change in manufacturing processes or tasks performed in a space will be changing. This could impact your operational requirements for a lighting project. Feasibly you could plan your project in stages to recoup the most from your energy-efficiency investment. The most benefit may be achieved by planning a full lighting re-design, giving you the exact lighting system that is best for your facility, your operational requirements and your goals. Be sure the current uses of the space and any future uses are considered when planning to re-light and upgrade or retrofit your building.

How Much Does A Retrofit Cost? Part 1

how much does a retrofit cost

How much does a lighting retrofit project cost? Or “How much is my lighting project going to cost?” is the question we hear first and most often, and it is truly the most difficult to answer of all the things our clients ask when we propose projects. Sometimes lighting professionals and energy-efficient lighting project designers can tell you the costs of fixtures, lamps, labor, and a whole host of other items that go into a lighting retrofit project; however, it is really very difficult to give an ‘average price’ or a ballpark price because the factors vary so widely from project to project. So, today we’re going to tell you all the cost factors that go into building your lighting project from the ground up. We are going to give you all the nitty gritty details and examples that can heavily affect not only the cost of your lighting retrofit, but the overall success of your project. We want to tell you how to go in armed with knowledge when you are ready to take on a lighting upgrade or retrofit project. Our first bit of advice is to read this article before you sign on any lighting project quote. Here is part one of our four part series:

FACTOR 1: YOUR FACILITY

Your building size, structure, hours of operation, your existing electrical service and even your industry can impact the cost of a lighting project. A reputable contractor isn’t going to give you a cookie cutter “One Size Fits All,” energy efficient fixture as the answer to the complex equation that is your lighting project. When you engage with the person that will be doing the lighting survey (auditing) your facility, be prepared to answer a lot of questions about your building and your existing lighting system. In order to put together the best project, they will spend a fair amount of time taking into consideration your entire facility, how it is currently working and how you need it to work in the future

How big is your building, or the area you want to include in the project? Oftentimes bigger spaces require more fixtures for more light, or those will taller ceilings will need to beef up fixtures; however, the greater the project cost, the greater the potential for savings opportunities.

What is your current electrical service? 120 volt system? 277 volts or 480?  This will affect the fixture configuration and in some cases the lighting technology available for your application.

What are your hours of operation?  How much energy you use on average can dramatically affect your rebate, energy costs and payback calculations.

Are you a candidate for daylight harvesting? Do you have many windows? What about sky lights? Perhaps it is dark outside or you have no windows.

General accessibility to the light fixtures will impact the cost of your project. Factors here include more than ceiling height and ceiling type. Project planners must also consider any equipment in the way of accessing the light fixtures such as: machinery, desks, furniture, displays, racking, or any items that may be stationary or immovable during the project.  Additionally, there may be objects that are light spread barriers, meaning to achieve your lighting needs, fixtures would be added. Another part of the general accessibility also includes the current schedule at your facility. How often are your spaces occupied? Are you open 24/7? Do you have special security clearance needs?

What is the working environment in your facility? The needs of a health care facility (open 24/7, with patients present) are going to vary from the needs of a retail store (open regular business hours, empty when closed). Even more dramatically different can be the environments in various manufacturing facilities, with a spectrum from food production, to light manufacturing to heavy industrial operations like a foundry, which is hot, dirty and can be very dangerous for anyone not trained to work in one.

How can I reduce operating costs at work?

It’s a common question and a concern for every business as modern times dictate we do more with less to achieve better results. In manufacturing, schools, retail businesses and other industries, the question, “How can I reduce operating costs at work?” and “What are the ways I can save money for my company?” are very, very common.  

There are many solutions out there to achieve savings at work, to help your company run more efficiently in these lean times. But one solution can be simple, direct, measurable and achievable. Today we are going to outline the ways a lighting retrofit can help advance your career and better your business.  

DIRECT IMPACT TO THE BOTTOM LINE  

It’s a fact that every business has lights turned on during business hours, and that light costs money. Retrofitting directly impacts your bottom line. Economic and environmental savings are measurable.  With a successful lighting upgrade you will be able to:

  • Reduce energy costs by reducing the number of watts used per lighting fixture
  • Reduce maintenance costs with longer life lamps such as T8 and LED technology
  • Streamline purchasing by reducing the types and quantities of lamps in your building
  • Build property value by updating the lighting system

IMPROVE APPEARANCES

Perhaps a part of your company’s success is directly related to its image and customer perception. Making a good first impression starts from the top down. For example, if the lighting is bad in a retail store, things are going to feel wrong. Most people won’t directly attribute this to the lighting, but by providing better light the products on the shelves and in displays will look inherently better. This could result in increased sales. We all know looks are everything. Here’s what improved lighting will get you:

  • Better color recognition, helps displays or products pop and gain attention
  • Upgraded lighting fixtures look clean and modern, or can be integrated more fully into building design
  • Areas with too little or too much light can be corrected for maximum effect
  • Interior and exterior lighting can affect the way clients or visitors perceive your building
  • Better light can mean better safety, security and building recognition

   
BE SEEN AS AN INNOVATOR & BUILD FOR THE FUTURE

As a part of making operations leaner, lots of employees these days are asked to wear many hats at work. If you can offer up a solution to help your company operate more efficiently or give insight to streamline future growth, do you think it could advance your career or help make your company more profitable? Here are a few reasons that suggesting a lighting improvement could help you be seen as an innovator:

  • This type of project can help attain larger company goals of sustainability and ‘being greener’
  • Suggesting a simple energy-efficiency measure for consideration could get you recognition
  • Quality lighting can positively impact productivity and is proven to have a measurable impact
  • Plan to ‘build for the future’ and reduce circuit load to allow for future expansion and additions
  • Design lighting projects can be planned in phases to help bridge gaps in innovation (HID to T5 to LED)
  • Add  occupancy or vacancy sensors and other wireless controls that can incorporate later into bigger building automation plans

Parking Ramp Lighting Retrofit Case Study

parking garage lighting ret

You can see this dramatic before and after, side by side while this lighting retrofit project is taking place. This client qualified for more than $23,000 in utility rebate incentive when they upgraded. They now have better light quality in their facility, increased safety for their patrons, and they are saving money and resources at the same time!

Facility Statistics: The Benefits of a Lighting Upgrade

Common lighting issues in parking garages include dark, shadowy areas and poor light quality. By replacing the existing High Pressure Sodium lighting with energy efficient 2 Lamp Vapor Tight Fluorescent High Lumen Fixtures that consume only 74 watts each, this facility is taking advantage of major energy savings. At the end of this project the client was saving 114 watts per fixture, reducing energy usage by over 50%!

Cost Savings: Does is really add up?

Before completing this project, TRC performed a full facility audit. This means all of the existing fixtures were counted, along with their rate of energy consumption and hours of operation, and a cost of operating was established. The new, more energy-efficient system was also proposed in the same way. The difference in energy usage totaled nearly $20,000 in annual lighting cost savings. 

Carbon Savings: What does it mean? 

Based on Kwh reduction from our facility lighting audit and using a Greenhouse Gas Equivalencies Calculator, we can determine carbon savings of 380,740.7 pounds of CO2 for this energy efficiency project. This is equivalent to keeping 37.4 cars off the road for a year, 16,699 gallons of gasoline saved, or 58 tons of waste recycled instead of landfilled!

Safety & Savings: Parking Ramp Lighting Retrofits

Parking ramp lighting and other exterior lighting applications are the latest frontier for energy-efficiency projects, and a lot of savings opportunities exist for building owners and managers in these projects.  Utility companies are even offering rebates for exterior lighting improvements, in some cases. Additionally, long-life lighting technology, like LED’s, and rugged fixture designs that perform well in varying weather are now available, making the feasibility and return on investment of these outdoor lighting projects even more appealing.

The importance of lighting design should take into consideration the function of a space, and this is true for parking garages and ramps, as well. For the tasks of driving and navigating a ramp as a pedestrian, fixture choice will influence the spread of the light and therefore the safety and security of the facility. Generally, these applications will shy away from a “cut off” fixture, which results in a cave effect, or dark ceiling which can strain the eyes and make it difficult to distinguish objects and shadows in an area. Not a great choice for place where people will be driving.

Instead, a better option would be semi-cut off or refractor, which will brighten the entire driving area, parking area and walls. Most parking ramp applications will want 5 foot candles per square foot as an appropriate amount of light for the basic tasks required in that space. With the semi-cut off or refractor style fixture, especially now with directional LED options, light can be directed to the places it is needed, without glare and without ‘spilling’ light beyond the intended area to create light pollution.

The Department of Energy offers this checklist to guide decision making for parking garage lighting, and recommends the following steps for a successful project:

1)  Conduct a complete inventory, including information on every fixture: wattage, burn hours, and existing light level.

2)  Decide whether to retrofit or install new fixtures is the best option. Consider fixture condition, and whether or not new lamp replacement options would fit into the existing fixture.

3)  Consider light quality and quantity. Be sure to take into account the importance of lighting design and the function of a space. Ask “what task must be lit?” and “where is it taking place?” In the case of a parking ramp or garage, the tasks will be driving, walking and identifying people and vehicles.

4)  Consider controls for transition areas. “Lighting Controls” can include daylight harvesting and occupancy sensors for dimming during no or low-traffic times.

5)   Take time to investigate utility incentives or rebate programs to help buy down the initial cost of the lighting products used in your energy-efficient retrofit project.

6)  Determine specifications for replacement or retrofit of the existing lighting system.

7)  Solicit bids.

8)  Create your life-cycle cost analysis, include your energy savings, cost reduction, simple payback and return on investment. What is important to you? A lower up front fixture cost, or the best long-term investment? Consider these when you create your life-cycle analysis.

9)  Purchase and install the new lighting system.

This reads like nine concise steps, but keep in mind that an entire industry exists to address your lighting needs. There really should be a funnier punch line to the joke, “how many lighting contractors does it take to change a light bulb?” – But in all honesty, every single lighting contractor you talk to will likely have a different answer for how to save energy and reduce your overhead. Most of them will probably be able to do that for you, but be sure the lighting products and installation configuration you choose is one that has your needs and lighting requirements at the forefront. Arm yourself with knowledge and the ability to choose the best project for you. Read the full DOE check list here

5 Ways to Control Lighting for Maximum Energy Savings

As you continue research for your lighting retrofit project, you will find many energy-saving methods available to you aside from simply reducing watts and energy used by the lamps you choose to use to light your facility. The most direct savings does come from this wattage reduction, but adding lighting controls to your lighting retrofit project can dramatically impact energy savings. Lighting controls range from fully automated control systems managed by computer programs,  to less technological, manual methods, some are even as obvious as “good occupant habits,” like always turning lights off in an empty room. But occupant habits aren’t always good and fully automated systems might be overkill for the lighting management of smaller facilities. 

These five ways to control lighting for maximum energy savings are all relatively easy to implement alongside your lighting upgrade to increase savings, but most of them can also be installed or carried out after a lighting project is completed.

1) Dimming

All light sources use less energy when dimmed and two primary types of dimming can be used, depending on the lighting application. Continuous dimming brings light levels down incrementally; often on a sliding type switch or you may have seen them on a knob which turns light levels up and down. This type of dimming offers a smooth transition between light levels. Step dimming is a method of firing some or all of the lamps in a fixture, depending on the need for light. Commonly referred to as bi-level switching, in reference to fluorescent lamp systems, this dimming method can offer more than 2 levels of light. This method is seen in classrooms, where only the lights in the front near a projection screen are turned off or is used to turn off lamps near a bank of windows on the end of one large room where less light is required during bright times of day.

2) High End Tuning

Tuning down the high end of your lighting system means to slowly adjust from 100% of your lighting system’s capability down to the most appropriate amount of useable light required for an area’s needs.  Example: Recommended lighting level (range in foot candles) for kitchens in the food service industry is 50-100 foot candles. Your facility may be lit at 100 foot candles with the current system, but employees are still able to safely and comfortably perform all required tasks at 75 foot candles. Over a period of days, by trimming off the top using controls, and setting the new ‘maximum’ light level at 80 foot candles, reduces overall energy usage. Typical lighting energy savings from high end tuning can be 10-20%.

3) Occupancy sensors

Using passive infrared (PIR), ultrasonic or dual technology, these sensors respond by turning lights ON when the presence of a human is detected and then automatically turn lights off when the presence is no longer detected for a specified amount of time.  The use of sensors is most suited to areas where lights are commonly left on when not occupied including:

      • Offices
      • Classrooms
      • Bathrooms
      • Storage areas
      • Conference rooms
      • Warehouses
      • Hallways / Corridors

4) Vacancy sensors

Using the same technology as Occupancy Sensors, these devices only turn lights off when no occupant is detected. Someone must manually turn the lights on in a space where vacancy sensors are employed. This may seem counter intuitive to some, but consider spaces such as offices where someone enters for only a moment to retrieve an item and then leaves. In this scenario, an occupancy sensor would turn lights on, and leave them on for 10-30 minutes depending on how they were commissioned, wasting energy in an unoccupied room. Vacancy sensors grant the highest level of energy savings because lights cannot turn on automatically.

5) Personal lighting control

By providing individuals the option to control light levels which accommodate the tasks and activities in a specific area, some facilities could see a 20-60% lighting savings.  The ability to adjust light levels in their own workspace, gives occupants the exact light level for their eyes and the task they are performing. There has been some research to suggest that in addition to energy savings, personal lighting control also increases productivity
