Affordability in Passive Housing

In 1977 the Saskatchewan Conservation House was built in Regina as a demonstration project. According to the Canadian Passive House Institute, this (right here in Canada) was the birthplace of Passive House science. Yet it was not until 1986 that the Passivhaus movement began to gain momentum within Germany.

Since then, the German building community has honed its methods over time and, at this point, there are over 20,000 Passive Houses in the world (source: CanPHI).

In its 2010 economic analysis of Quebec’s Montebello Passive House, CanPHI reports that the total incremental costs required to reach the Passive House standard within a new 1550 sq. ft. single-storey detached house were $26,000. However, due to cost-savings resulting from its remarkable energy performance (80-90% more efficient that a home built to code), $26,000 was saved in heating costs within a mere 16.5 years (assuming a modest annual fuel price increase of 3%).
