Early Performance Results From A Zero Net Energy Community

摘要

West Village, a multi-use project at the University of California Davis, represents arnground-breaking sustainable community incorporating energy efficiency measures and on-siternrenewable generation to achieve community-level Zero Net Energy (ZNE) goals. Sited on overrn200 acres, when complete the community will provide housing for almost 2,000 students, 343rnhomes for faculty and staff, mixed-use buildings, and other amenities. The project’s vision is tornmaximize the community’s sustainability by reducing building energy use, utilizing renewablerngeneration, and encouraging alternative forms of transportation. The project has completedrnconstruction of 683 student apartments over a three year period. Data collection efforts to daterninclude ongoing logging of PV generation and apartment level utility consumption, detailedrnmonitoring of innovative systems, and occupant behavioral surveys. This paper will discussrnresults from Phase I student housing (192 apartments), including:rn1.How successful the student housing segment is in reaching the zero net energy goals;rn2.What role occupants play in achieving community goals;rn3.What role central heat pump water heating plays, and performance results; andrn4.Lessons learned in shifting from building to community level zero net energy goals.
