The Zero Net Energy Production Builder Demonstration project provides guidance to five residential home builders on building to specifications that enable a home to achieve ZNE, including assistance with design options, building practices and modeling analysis.

The first report (attached below) details the design and construction process of a ZNE home built by Habitat for Humanity of San Joaquin County. Key features of interest are integrated design solutions, a ¾  ton mini-split heat pump, and extensive advanced framing with a very low framing factor, which contributed to a ZNE package that saved money relative to the builder’s standard practice.

A second pdf attachment is an eight page case study that summarizes the above report's findings.

The third pdf attachment is a report that details the findings from a full year of monitoring the energy consumption by end use of the home.
