ZETA Communities Zero Energy Modular Home in Oakland, CA

ZETA Communities is a startup company that has a mission of building energy efficient and/or net zero modular houses at costs competitive with local construction. They recently completed their first prototype, the live-work townhome: an infill project located in a mixed industrial/artist/residential urban neighborhood, within walking distance of a mass transit station. The plan provides a ground floor work studio, 2 bedrooms, light-filled great rooms, decks, and sustainable landscaping, in addition to a one-car parking garage. BSC worked with ZETA and Daniel Smith & Associates (DSA), the architects who were previously associated with the project, and have extensive experience in sustainable design and passive solar projects. Energy analysis showed a 45% savings with respect to the Benchmark when not including the photovoltaic system; inclusion of the 5.4 kW PV system showed a savings of 95%. The analysis also showed nearnet zero performance, assuming Building America operating conditions; prudent operation by a homeowner will likely result in net zero performance. The project has received a LEED-H Platinum rating, 217 Green Point Rating, and EPA’s highest indoor air rating, Indoor airPLUS. The house is currently under contract, and the owner is scheduled to take occupancy in March 2010.
