DOE Zero Energy Ready Home Case Study: Green Extreme Homes & Carl Franklin Homes, Garland, TX

Case study of a DOE Zero Energy Ready affordable home in Garland, TX, that was the first retrofit home certified to the DOE Zero Energy Ready home requirements. The construction team achieved a HERS score of 59 without PV by gutting the home to the 2x4 studs, then filling the walls with R-22 of closed-cell spray foam, covering the attic floor with R-39 of closed-cell spray foam, covering the underside of the floor deck with R-39 of closed-cell spray foam and installing new high-performance windows, appliances, and lighting. A minisplit heat pump with 5 indoor heads heats and cools the home.
