475 High Performance Building Supply provides essential building knowledge and components to building professionals. 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 e-commerce-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.

A Yard & A Half Landscaping Cooperative was formed in 2013 to preserve and continue to develop a locally-owned, safe, just, and democratic workplace in an industry where workers often face exploitation, wage theft, and hazardous working conditions. Participation in the cooperative is a financial and career investment for members, not just a job. Worker-owners participate in professional development, learning transferable skills and creating economic growth and self-sufficiency. We also share in the profits of our labor, allowing us to reinvest in our own local economy, communities, and families.

At Ace Energy Services, Inc. we apply our knowledge of building science by focusing on two of the most important components in meeting state energy codes—the building enclosure and mechanicals. We advise on how to make tight building enclosures often assisting with effective air sealing measures. We design and install the most advanced air-source heat pump systems. This combined with implementing a practical ventilation strategy creates some of the most energy efficient and comfortable homes. We don’t just test and consult, we implement measures all the way through to satisfactory system operation including homeowner or occupant education and training.
