What is a passive house?

Passive House (PH) is a European concept and performance based building standard that focuses on dramatically reducing or eliminating the need for an active heating or cooling system to maintain a comfortable interior climate. This is achieved through efficient design that utilizes passive heating and cooling techniques and an optimized building envelope that is airtight, super insulated and fitted with super energy efficient windows and a heat recovery ventilation system (HRV).

The annual energy use for heating and cooling of a Passive House cannot exceed 15 kWH(m²a) and the total energy use cannot exceed 120 kWH(m²a). To put that into perspective, this is approximately 10% of the energy required to heat and cool a conventionally built home in Canada.


Why Build to the Passive House Standard:

  • Energy Efficiency: Up to 90% savings for heating and cooling compared to current code construction.
  • Healthy Buildings: Constant circulation of fresh, filtered air, excellent noise control and comfortable, consistent temperatures.
  • Sustainable Development: Building to the PH Standard offers a construction solution that dramatically increases building efficiency, thus reducing energy dependence, making PH a great starting point for achieving Net Zero, LEED, The Living Building Challenge and other CO2 initiatives.
  • It Works: There are approximately 30,000 PH structures world-wide that have proven time and time again the accuracy of PH building requirements and the PH design software.
