EnVision, a new zero net energy (ZNE) community in Clovis, California, broke ground August 2017 and is expected be one of the largest to date in the Golden State. The development will be California’s largest detached, single-family ZNE community to date with 36 homes.
“We know that at some point the state will require everyone to do this. Why not learn it ahead of time, get used to it, and figure out how to bring costs down earlier?” said Brandon De Young, executive vice president for the development company.
The EnVision community will feature eight floor plans ranging from 1,690 to 3,820 square feet with prices starting in the $300,000s. Cost-effective energy efficiency measures to be installed include:
- Airtight construction for a superior thermal envelope
- 2×6 advanced framed walls
- Dense insulation
- Dual pane windows with solar control
- High-efficiency air construction system
- Heat pump water heaters
- Smart controls with smart phone application
The project is part of Pacific Gas and Electric Company’s (PG&E) Zero Net Energy Production Builder Demonstration program that supports California’s ZNE construction goals. Through the program, PG&E provides design consultation before, during and after construction of the home. Once homeowners move in, PG&E will monitor the house for 12 months to evaluate energy performance as well as identify opportunities for future enhancements to design, construction or occupant considerations for ZNE homes. Energy consumption and production data will also be analyzed to assess broader impact of the development’s photovoltaic (PV) systems on the electric grid.
Homeowners will have the option to purchase a solar array as an upgrade or lease a PVs from Tesla. The cost of the EnVision homes is estimated to be about an $8 per square foot more than a conventional home. Accounting for reduced or negative energy bills, the residents will save more money than they spend, according to DeYoung Properties.
