We design ready-to-build zero energy homes and retrofits with readily available materials and tested, reproducible assemblies.  We make housing healthier and more resilient.

 

We provide curriculum development, education and workforce training, technical assistance and consulting. 

 

We offer scaled pricing to eliminate barriers to access. We work with homeowners, community organizations, and others invested in just housing.

As a public benefit corporation, we shape our work toward purpose, not profit:

• to enable and accelerate equitable and widespread adoption of sustainable solutions for housing; and

• remove barriers to individual and community needs for healthy, affordable, durable homes built to operate without burning fossil fuels.

​

Our mission is to provide sustainable housing solutions for a just transition to a resilient, clean-energy society. Our vision is an equitable transformation of housing and home building for the next generation.

A Zero Net Energy home uses renewable energy to produce as much energy each year as the house consumes each year. This means that over a year, your energy bills will total zero.

​

Our approach to zero net energy design:

• Optimize energy conservation with passive solar design, airtight construction and extra layers of insulation.

• Utilize super efficient mechanical systems, lighting and appliances.

• Operate with all-electric energy use, so no fossil fuels are burned on site.

• Size a solar array to meet the annual energy load of the house.
