Each home in the Rainbow Passive House Duplex is 1,500 square feet and comes with an unfinished basement, three bedrooms, and two bathrooms. The home achieves a 90 percent reduction in energy use because of its super-tight envelope, high performance cellulose insulation, a solar hot water system, high performance heat recovery ventilation system, and a subsoil heat exchanger.
The Rainbow Passive House Duplex was built using a prefab panelized system with local materials by BC Passivehouse, which is Canada’s first manufacturing plant prefabricating a panelized system that adheres to the PassivHaus standard. Marken Projects and Dürfeld Constructors handled the assembly and construction (see a time-lapse video here).
“Showcasing affordable high performance building design and construction was one of the main goals for this project,” says Alex Maurer, director of Marken Projects. “At the same time using regional products from sustainable sources where possible was as important.”
