Finished Passive House in Toronto

A building standard that is truly energy efficient, comfortable, affordable and ecological at the same time.
Passive House is not a brand name, but a construction concept that can be applied by anyone and that has stood the test of practice.

Yet, a Passive House is more than just a low-energy building.

  • Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new builds. In terms of heating oil, Passive House buildings use less than 1.5 litres per square meter of living space per year – far less than typical low-energy buildings. Similar energy savings have been demonstrated in warm climates where buildings require more energy for cooling than for heating.
  • Passive House buildings are also praised for their high level of comfort. They use energy sources inside the building such as the body heat from the residents or solar heat entering the building – making heating a lot easier.
  • Appropriate windows with good insulation and a building shell consisting of good insulated exterior walls, roof and floor slab keep the heat during winter in the house – and keep it out during summer.
  • A ventilation system consistently supplies fresh air making for superior air quality without causing any unpleasant draughts. This is e.g. a guarantee for low Radon levels and improves the health conditions. A highly efficient heat recovery unit allows for the heat contained in the exhaust air to be re-used.

*Dependent on lifestyle and energy consumption.

Windows and Doors:

Passive House certified three pane windows.

50% more energy efficient than standard two pane windows

Airtight Building Envelope

Passive House requirement for airtightness: 0.05 per 50 pascals (ACH50), 41 Northcote achieved a level of 0.0495 per pascals, Ontario Building Code requires 3.5 per pascals.

Thermal Insulation

Total R-52 for Walls, Ontario building code requires an R-24. See diagram below.

Continuous 6” Insulation around building structure greatly reduced thermal bridging, except for north wall.

Roof Insulation is: R-60, Ontario building code requires an R-31.

HFO Honeywell spray foam insulation. Offers a Global Warming Potential of 1-year vs standard 100—years of current spray foam options – 99.9% lower!

Thermal Bridging

Due to 6” continuous insulation we have very minimal thermal bridging.

Ventilation and Heat Recovery

Whole house ventilation HRV, offers fresh outdoor air, while removing stale indoor air.

Heat Source

Heat pumps are ranked among the most energy-efficient and cost-effective ways of heating and cooling your home, and Mitsubishi Zuba High Efficiency ducted heat pump systems provide unmatched heating and cooling capabilities.

The Mitsubishi Zuba System keeps your home consistently cool during blistering hot summer days and toasty warm during those bitter cold winter nights, even if the temperature hits -30°C and below.

Heat Pump Hot Water Tank

Heat Pump Water Heather (HPWH) technology does not generate heat directly. It moves heat from one place to another. Heat is taken from the air in the basement or utility (or sometimes from outside) and transferred to a tank of water.
