This social housing project comprises 54 units built around a landscaped central courtyard in Griffintown. The project has been selected by the SHQ as a Demonstration Project for the implementation of new approaches to the construction of healthy, resilient housing adapted to climate change. A monitoring programme will also begin to measure levels of energy consumption and comfort after occupation, and the homes are always walk-through, thus benefiting from double exposure and natural ventilation. A resilient building envelope ensures energy efficiency through thick and continuous insulation, air tightness, elimination of thermal bridges and high performance windows and doors. The thermal mass in the floor system also contributes to passive heating in winter and temperature modulation in summer. These passive systems are complemented by an efficient centralised HVAC system.
