Greenbuild, the world’s largest conference and expo dedicated to green building, takes place November 18-23 in Philadelphia. This year’s huge Passive House presence is a reflection of the growth of the Passive House standard in the US.

GREENBUILD 2013 is to feature six presentations that focus on Passive House building, three building tours, and on the GREENBUILD EXPO floor there will be a PASSIVE HOUSE ZONE organized by the North American Passive House Network (, featuring manufacturers and service providers that specialize in Passive House building.  

Passive House thermal comfort is achieved to a maximum extent through passive measures such as insulation, heat recovery, passive use of solar energy and internal heat sources.  Passive Houses can affordably reduce heating energy demand by up to 90%, while providing the most comfortable and healthy indoor environments.  These features also form a safety measure in extreme weather events and power outages by making indefinite sheltering in-place without heating possible.

From the growing necessity to reduce carbon emissions, to the Post Hurricane Sandy demand for “passive survivability” there is growing acceptance of Passive House buildings which will be demonstrated on the national stage of GREENBUILD 2013.
