The Walmart Supercenter in Leavenworth, Kansas, offered a test case to determine whether an LED system could meet the CBEA specification and be competitive with conventional systems when maintenance and energy costs were factored in. The LED system was compared to two systems: a 1,000-watt (W) pulse-start metal halide (PMH) and a 400-W PMH. This case study provides initial results and results after two years.

This document provides a framework for standard measurement and verification (M&V) of lighting retrofit and replacement projects. It was developed to provide site owners, contractors, and other involved organizations with the essential elements of a robust M&V plan for lighting projects. It includes details on all aspects of effectively measuring light levels of existing and post-retrofit projects, conducting power measurement, and developing cost-effectiveness analysis. This framework M&V plan also enables consistent comparison among similar lighting projects, and may be used to develop M&V plans for non-lighting-technology retrofits and new installations.
The Federal Energy Management Program (FEMP) Outdoor SSL Initiative encourages the federal sector to lead a large-scale implementation effort focused on Solid State Lighting (SSL) application. This fact sheet provides an overview of existing outdoor SSL resources developed by the U.S. Department of Energy’s SSL Program and other federal initiatives, as well as general SSL resources.
The Commercial Building Energy Alliance (CBEA) Lighting and Electrical Project Team developed a performance specification to help building owners and operators maximize the benefits of converting to solid-state lighting (SSL) technology from traditional high-intensity discharge technology. This specification provides information about both the luminaire and how the site should be lighted. It can be customized as building owners work with lighting designers, engineers, or SSL manufacturers to provide lighting solutions for different locations.
The Commercial Building Energy Alliance (CBEA) Lighting and Electrical Project Team developed a High-Efficiency Troffer Lighting Specification that sets performance requirements for high-efficiency LED and fluorescent troffer products in 2x4, 2x2, and 1x4 configurations. While LEDs have a strong potential to meet this specification, the specification is technology neutral.
The Commercial Building Energy Alliance (CBEA) Lighting and Electrical Project Team developed this performance specification to help commercial building owners and operators maximize the benefits of converting from traditional HID technology to high-efficiency alternatives. This specification provides information about both the luminaire and how the site should be lighted. Owners and operators should work with lighting designers, engineers, and luminaire manufacturers to create lighting solutions for specific locations.
This case study details Cleveland Clinic’s conversion to LED lighting in its six-story, 3,000-space 100th Street parking garage, using the Commercial Building Energy Alliances (CBEA) High-Efficiency Parking Structure Lighting specification. Cleveland Clinic used the specification to prepare its request for proposals, which was sent to six manufacturers, with five submitting bids. The case study details the criteria used to evaluate the bids and illustrates a comparison between the existing 200-watt high-pressure sodium (HPS) system and the LED replacement system.
This brochure provides information on High-Efficiency Troffer Lighting Specification Benefits and Energy Savings. High efficiency troffers that meet the specification are up to 45% more efficient on a one-for-one basis compared to traditional fluorescent troffers.
