CCHRC continues to raise the bar for energy efficient, affordable housing in the North. The building addition will go entirely off fossil fuels for heating with about 12 solar thermal collectors and a pellet boiler to heat 10,000 gallons of seasonal storage. Thermal storage offers a way to use renewable energy and bridge months without much solar gain. This technology is tailored to cold climates, where heating demand is highest and solar is not always available. The research will be shared with the building, energy, homeowner and policy communities to make sure everyone benefits from what we’re learning. As you’ll see on the following page, CCHRC is working with partners around the state to study durable foundation designs, technologies like air source heat pumps, and healthy building principles used to develop sustainable, affordable housing in a variety of climates. In the Sustainable Village chapter, we share costs from the various building systems used so you can compare different foundation, insulation, and mechanical systems. Thank you for being part of our mission.
