The federal government is the nation’s largest property owner, maintaining a portfolio of nearly 9,600 buildings that span over 375 million square feet. It’s the nation’s largest energy consumer, as well. The GSA’s 2024 P100 Facilities Standards for the Public Buildings Service — a key document guiding building design and the purchase of products for federal and other public entities — now points project actors to the DLC’s LUNA Technical Requirements and Qualified Projects List for certain types of outdoor lighting at public facilities. Specifiers, designers and installers wishing to identify outdoor lighting products for use in federal and other public buildings can find and compare LUNA-listed luminaires by creating a free myDLC account and then searching the LUNA QPL.  Federal Government Now Requires Energy Efficient Outdoor Lighting Products that Reduce Light Pollution at Thousands of Government Sites and Facilities | EC&M
