The zHome project was an overall success. Its educational campaign reached more than 13,000 people and its unprecedented standards led to the development of the Built Green Emerald Star external link certification level. Most importantly, it demonstrated that zero net energy homes are achievable, attractive, and livable.

zHome was a pioneering project. It was the first net zero energy townhome complex in the United States. It was built to rigorous environmental benchmarks and aimed to demonstrate that deep green housing could be realistic for the average person.
Several years after the zHome units sold and homeowners moved in, the team returned to the project to assess the outcomes and found that zHome reached the benchmarks that had been set for its development. The assessment included both the quantitative performance measures and qualitative homeowner satisfaction measures. The zHome white paper external link provides in depth insights into how the homes are performing and the lessons learned from the project.
