The Rideau Residence did not set out to be the First Residential Certified Passive House in Canada back in 2010 (a year after the Austria Haus in Whistler). The intention was simply to design and build the best house for the site using as much local material and mechanical equipment as possible. It wasn’t until the impressive 0.57 ACH air test that the idea of Passive House certification for this LEED Platinum home came to the fore. The result, as they say, is history.
