Parking Garage LED Lighting Retrofit Case Study

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!
