The International Living Future Institute (ILFI) is a nonprofit working to build an ecologically-minded, restorative world for all people. Using principles of social and environmental justice, ILFI seeks to counter climate change by pushing for an urban environment free of fossil fuels. ILFI runs the Living Building Challenge, which is the world’s most rigorous green building standard, not to mention several other programs: the Living Product Challenge, the Living Community Challenge, and the Reveal, Declare and Just labels. These programs develop a green framework for living in a 21st-century world.
The PHIUS+2015 Passive Building Standard released by Passive House Institute US (PHIUS) in 2015 is the first and only passive building standard in the world based upon climate-specific comfort and performance criteria aimed at presenting an affordable solution to achieving the most durable, resilient, and energy-efficient building possible for a specific location.
