475 helps make more durable, resilient, ecological, and energy-efficient buildings that optimize occupant comfort and health. We enable the building improvements required to dramatically reduce our energy demand and address our climate crisis. We are an eCommerce-based catalyst in the transformation of US construction to high-performance, low-energy and Passive House buildings. The name "475" is a reference to the heat demand requirement of the Passive House Standard, 4.75 kilo BTUs per square foot per year. Passive House is the gold standard for high-performance construction today.
