Madrona Passive House

Net Energy Positive

Designed by SHED Architecture & Design

Built by Hammer & Hand

 

Madrona Passive House, a new Seattle home designed by SHED Architecture & Design and built by Hammer & Hand, combines contemporary design with high performance building to create an environmentally responsive and resource-efficient house.

The home’s airtight, super-insulated building envelope and passive design minimize energy consumption while providing superior thermal comfort to occupants. A heat recovery ventilator supplies constant fresh air to the home’s interior while recovering 90% of thermal energy from exhaust air for reuse inside. A 9.8 kW rooftop solar photovoltaic array will provide enough energy to offset most, perhaps all, of the home’s energy consumption on a net annual basis. To manage stormwater the project employs permeable pavers for site hardscape and two cisterns to capture and control rainwater from the home’s roof and the green roof on the garage.

By investing in sustainable site development strategies, efficient building systems and an advanced envelope, the project aims to respect the home’s environmentally critical site and achieve one of the world’s most demanding building energy standards: Passive House.
