The Huff-Collins residence in Ironto, Virginia harnesses the revolutionary building performance of Passivhaus construction to deliver 70% savings in energy use at a tiny increase in construction cost, easily recouped by reduced utility bills. Passivhaus was the perfect solution for the clients, with its win-win for the environment and the pocketbook. She’s a biology professor concerned about the future of the planet. He’s concerned about conserving household financial resources.
The project applies the standard Passivhaus suite of building techniques: super-insulated, airtight building envelope, high performance windows and doors, constant fresh air provided by an energy recovery ventilation system, and smart siting and solar design. A passive ground loop pre-heats and pre-cools intake air, and solar thermal systems boost energy performance.
