Projects Updates/The Results
Progress has been slow in 2020 due to COVID-19 which delayed construction of the two ZNE homes. Progress in 2020 includes finishing installation of HVAC, water heating, and drywall at both homes. The team is aiming to complete construction and collect performance data in 2021.The project team also finalized an eBook which details the innovative energy efficient construction practices being utilized in the ZNE homes and conducted builder training seminars. The recipient offered a series of training webinars on building affordable zero net energy homes in November 2020. Additional seminars will be held in the future. These webinars were a direct result of the research project.
The project implements lessons learned from previous high performance housing research and measures the results in two new homes being built in partnership with Habitat for Humanity. Both houses include advanced architectural design features, high performance enclosures, advanced heating, ventilating and air conditioning systems, and low-cost water heating systems. One all-electric home and one mixed fuel (combined electric and natural gas) home will demonstrate the respective cost-effectiveness of each set of features. In addition to measuring results from actual occupancy, the project is developing a guide to affordable residential zero net energy design and construction, a training curriculum, and offers training opportunities based on project efforts. The houses are in a disadvantaged community in Stockton.
The advanced integrated energy efficiency packages included in this project could reduce annual energy costs for homeowners by up to 50 percent.
