Abstract

The Davis “Future Renewable Energy and Efficiency” (DavisFREE) project developed detailed and comprehensive integrated renewable energy and enhanced residential energy efficiency plans to guide the City of Davis in achieving climate action and energy reduction goals related to building energy usage.

The benefits to California ratepayers include contribution to the State of California’s goals for greenhouse gas reduction, renewable portfolio standards, and localized renewable energy production. The research provides new information and marketing approaches for the state’s interest in zero net energy building design and construction. The research also provides new information for California’s Integrated Energy Policy Report updates, cost of generation supply curve modeling, and approaches for development of databases and tools to guide other communities in analyzing the potential for locally-owned renewable energy generation systems.

The primary research tasks for DavisFREE included:

  1. Database development using data extracted from the city’s Geographic Information System (GIS) specific to building-related energy usage; and integration with the PG&E Green Communities community-wide energy usage database and customer target marketing tools.
  2. Analysis of locally-available renewable energy resources, including regional availability of direct solar, wind, biomass, geothermal, and micro-hydro for potential community-scale electricity generation.
  3. Cost of generation modeling for locally-available renewable energy resources.
  4. Development of zero net energy guidelines for existing residential buildings.
  5. Development of a solar thermal water heating deployment plan and marketing materials.
  6. Community engagement activity planning to deliver the results of the research.

DavisFREE concluded that locally-owned community-scale renewable energy development is viable for Davis, and that zero net energy conversion for existing residential buildings is feasible and cost effective. The results and products of this work are expected to be delivered to Davis residents through multiple implementation strategies.
