In 2016, Mark Rosen, an Ottawa architect and Certified Energy Advisor/Passive House Designer, and Meghan Rosen, a graphic designer, designed and built their home following the principles of the international Passivhaus/Passive House building standard. The most fundamental elements of the standard are super-insulation, extreme air tightness, and very high-efficiency ventilation.
Built on an infill lot in Hintonburg, the house is a single family home that uses roughly 85% less energy for heating than a standard new home. It is built with super-insulated walls, ceilings and floors, and is extremely air-tight (0.46 ACH). It showcases a shallow geo-thermal ground loop, grey-water ready plumbing system, high efficiency ventilation system, and heat pump hot water tank. The Wander House is one of only a handful of houses in Canada to target the rigorous international PassivHaus standard.
