Mosaïq is a six-storey, 108-unit affordable housing building for families, seniors and couples at 811 Gladstone Avenue in the heart of downtown. The building is fully accessible and 15 percent of the units are for those with reduced mobility.
The largest Passive House residential building in Canada
While designing Mosaïq, Ottawa Community Housing collaborated with sustainable building experts from the Savings by Design program to optimize energy performance, build better than code and earn financial incentives.
The project was designed to Passive House Standard, which makes it highly energy efficient. Key priorities in developing the project included airtightness of the building envelope, triple-glazed windows and doors, and a ventilation system that recovers up to 85 percent of the heat from outgoing air to heat incoming air.
Sustainable communities for future generations
“Ottawa Community Housing is committed to sustainable design practices that reduce our carbon footprint and help us build communities that preserve the earth for future generations,” said Cliff Youdale, Chief Development Officer, Ottawa Community Housing. “To do that, we engage partners early in the process to ensure we leverage all available tools and resources.”
“Thanks to the Enbridge Gas Savings By Design program, we worked together to reduce greenhouse gas emissions and support our goals.”
