A house in Bellingham, Washington, demonstrates innovative water and energy systems that meet the standards of the Living Building Challenge.

THE BIRCH CASE STUDY HOUSE was developed using the Living Building Challenge as a guide. The primary goal of this project was to implement numerous sustainable strategies, highlighting the successes and failures when designing, permitting and constructing Living Buildings.

To help realize the project, [bundle] design studio partnered with non-profits and building product manufacturers. Throughout construction, [bundle] hosted a workshop series with Sustainable Connections to present green materials and strategies to the local building community. [bundle] also partnered with Northwest Energy Efficiency Alliance (NEEA) for the NextStep Homes program and with WSU to field test a CO2 heat pump that is used for domestic hot water and radiant floor heating.
