Research Gap Analysis for Zero-Net Energy Building

California has adopted numerous policies to reduce energy use from the building sector including the California Public Utilities Commission (CPUC)’s Long-Term Energy Efficiency Strategic Plan, which calls for all new residential construction and all new commercial construction in California to be zero-net energy (ZNE) by 2020 and 2030, respectively. This project identified high potential technologies along with their research, development, demonstration, and deployment challenges to achieving these ZNE goals with a focus on the commercial and multifamily residential market sector. The team also developed a prioritization framework based on objective factors and weights that help define ZNE scenarios to provide context for assessing technologies. The resulting work includes technology details with research gaps and the prioritization frame, as well as the background of literature reviewed and stakeholder input through surveys and interviews.
