DOE Updates High-Efficiency Parking Structure Lighting Specification

Dept. of EnergyA CBEA Project Team has updated the High-Efficiency Parking Structure Lighting Specification. First released in 2009, version 1.1, released on February 15, 2012, has updates related to IES TM-21 and anticipated RP-20 requirements. In addition to focusing on the efficiency of each of these technologies, the Project Team investigated how the role of controls and the specific use of each technology can lead to even greater energy savings. The maximum allowed installed power density within the specification is 40% below ASHRAE/IES Standard 90.1-2007. Additional energy savings are possible from the use of lighting controls and daylighting.

Questions on this specification should be sent to the Pacific Northwest National Laboratory (PNNL) at
