And the Winners Are…

TPP-2015-12-And the Winners Are...By Michael Myer and Marye Hefty

In 2015, 18 organizations won Phase II Lighting Energy Efficiency in Parking (LEEP) Campaign awards by saving an average 60 percent in parking lighting energy. Since LEEP was launched in 2012, award winners have achieved 200 million square feet of high-efficiency-lighting parking for combined energy savings of 69 million kilowatt-hours nationally, which is equivalent to roughly the same amount of energy used annually by 6,400 homes. (Other laudable participants contributed to even greater savings nationally.)

IPI will present the next round of LEEP Awards at its Conference & Expo in May 2016 (see details at the end of this article).

How Can LEEP Help Parking?
Advances in lighting technology, lighting controls, and design practices since 2010 have created ample opportunities for energy savings for parking facilities. Realizing this, in 2012 the Building Owners and Managers Association (BOMA), Department of Energy (DOE), Green Parking Council (GPC, an affiliate of IPI), and International Facility Management Association (IFMA) started the LEEP Campaign; IPI was then invited to join as an organizer as the largest and leading association of parking professionals. LEEP’s overarching goal is to reduce the energy consumed by parking facilities through the installation of high-efficiency lighting.

LEEP makes energy-use data accessible, recognizes positive accomplishments, and facilitates ­energy-saving actions among multiple stakeholders. The LEEP website has calculators to help determine the economics of a possible lighting change and lists lighting incentives and performance specifications for high-efficiency lighting for parking lots and structures.

Finally, the LEEP Campaign offers limited technical assistance via independent third-party entities that can provide lighting recommendations to sites, answer questions about technology, make suggestions about equipment and layout, and provide other recommendations (technical assistance is barred from doing actual lighting designs).
Of the 21 individual parking facilities considered in Phase I and 23 in Phase II, the average payback was less than six years. A few factors are important to consider:

The cost of electricity can vary significantly across the U.S. Site managers need to research electricity costs for specific sites when considering different lighting installations.

To stay competitive with LEDs, virtually all light sources now offer long-life options with manufacturers claiming lives of their products at 40,000; 60,000; or even 100,000 hours. By upgrading the light equipment to longer-life equipment, annual maintenance costs are reduced.

Many regional energy organizations offer rebates for installing high-efficiency equipment and controls for parking facilities. The LEEP website includes a list by state and by application (structure vs. lot) of incentives from across the country.
