An Engineer Builds the Net-Zero Passive House of His Dreams in West Vancouver, Dwell, April 2, 2020.
James Dean believes his 4,000 net-zero-energy home is the future of construction. Situated on the southern slope of the mountains along English Bay, with three stories of wall-to-wall glass, it gathers effusive sunlight during the cooler months, reducing the need for heating. Terraces flow from each level, blocking direct sun during the hot summer months.
Built of four-and-a-half-inch prefabricated cross-laminated timbers, the structure was erected in a few weeks rather than months, reducing construction costs and exposure to rain. And the volume is insulated by 17-inch walls, which retain heat and virtually eliminate thermal bridging—the conduction of heat through the building envelope—to maximize comfort.
