Passive House Institute US (PHIUS)


Available in Oregon, Washington, Idaho, Montana

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. Despite its name, PHIUS standards are not limited to houses but can be applied to buildings of all use types. Buildings designed and built to the PHIUS+ 2015 Standard consume 86% less energy for heating and 46% less energy for cooling (depending on climate zone and building type) when compared to a code-compliant building (International Energy Conservation Code IECC 2009).
