SMUD House of the Future Demonstration

La Valentina North Affordable Townhomes Near zero energy building report SMUD’s Home of the Future Demonstration Program Prepared by Mike Keesee, Project Manager Energy Research and Development Sacramento Municipal Utility District September, 2012 Revised by TRC Energy Services to include post construction performance monitoring November, 2014

In 2009, SMUD partnered with owner/developer Domus Development LLC on the La Valentina North, an 18-unit affordable townhouse, Home of the Future (HOF) project. La Valentina was a research and demonstration project that combined advanced construction techniques with high efficiency building features and equipment and a virtual net metered solar photovoltaic (PV) system. Project goals included: 1. Operate as closely as possible to a zero net use of energy, including cutting annual source energy use by 80% and achieving zero net peak demand during SMUD’s 4 to 7 p.m. summertime peak period. 2. Incorporate advanced framing techniques and HVAC design.

As part of La Valentina’s design, project team members met with Domus and its design team to review design strategies and to develop a list of efficiency features to be included to achieve La Valentina’s energy performance goals. The National Renewable Energy Laboratory (NREL) provided critical technical assistance in developing the project’s energy efficiency measures. The project team conducted energy analysis using EnergyPro software, which models energy use for Title 24-regulated loads. The analysis showed La Valentina units on average would use 54.4% less TDV energy than a project built to the California 2008 Title- 24 Standards, including 63% less electricity and 48% less natural gas (
