PulteGroup, the third largest builder in the country, unveiled their zero net energy (ZNE) prototype in a ceremony on June 16, 2016. This ZNE prototype was developed as part of PG&E’s ZNE Production Builder Demonstration, which provides design consultation, construction visits, and a year of performance monitoring to select builders.

Resource Refocus provided general project oversight and data analysis on behalf of PG&E, BIRAenergy provided design consulting, and Davis Energy Group is conducting the performance monitoring.

Habitat for Humanity of San Joaquin County

For Habitat for Humanity San Joaquin Valley, the ZNE measures, in aggregate, reduced the net cost of the home by nearly $3,000 as a result of a holistic, highly integrated approach. For example, moving from 2x4 16” o.c. wall construction to 2x6 24” o.c. saved money on lumber and improved the thermal envelope, which allowed the HVAC system to be downsized. The full design and construction report can be found here.
