Passive House construction catching on in Portland

The Passive House building method uses an airtight building envelope and energy calculation software to reduce energy consumption compared to a standard home by 90 percent.

Nathalie Weinstein of the Daily Journal of Commerce reports that the Passive House concept was engineered in Germany in the 1970s, and is gaining momentum in Portland.

Current wind and solar technologies cannot meet the energy demands of buildings on their own, said Stephen Aiguier of Green Hammer Building Contractors. But Passive House, he added, could figure into pursuit of the 2030 Challenge, which seeks a 50 percent reduction in buildings’ energy consumption by 2030.

“Passive House allows you to get to that reduced energy consumption today rather than struggling to generate all of your power by on-site solar and wind,” Aiguier said. “When you look at emerging energy economies, Germany tops the list. We are massively behind the curve, and this is a well-vetted and engineered system.”

The passive house concept was first conceived in the late 1980s with the first house being built 1990. There was a smaller movement of building supper insulated homes in the 1970s in the US and Canada. This North American work is what gave the inspiration to develop the passive concept and criterion.
