Prefab multifamily is the new black these days, which is why weâ€™ve been watching startup ZETA Communities with interest.Â ZETA, which stands for Zero Energy Technology and Architecture, finished these live/work, net zero energy townhomes in Oakland and has a number of other projects in the works.Â The townhomes achieved LEED Platinum certification, a 240 green point rating, and an EPA Indoor airPLUS, the EPAâ€™s highest indoor air rating.Â Each home is 1,540 square feet with two bedrooms and a single-car garage.Â And theyâ€™re packed with some of the following green elements and strategies:
- Passive solar design;
- Sound attenuation;
- Ultra-efficient envelope/cellulose and spray foam insulation;
- R-5/R-7 Serious Materials Windows;
- Air-to-air heat exchanger;
- Heat recovery ventilator;
- Wastewater heat recovery system;
- Energy Star appliances;
- LED and CFL lighting;
- Natural ventilation and natural lighting;
- Low VOC finishes and zero VOC int/ext paints;
- Use of FSC certified lumber;
- Use of low cement, high flyash concrete;
- Use of sustainable and recycled content finishes;
- Low flow plumbing; and
- Drought-tolerant landscaping.
ZETA constructs their projects piece by piece in an off-site facility and delivers the modules to site at about 80% completion.Â After delivery, ZETA finishes the rest, and according to the San Francisco Chronicle, a two-bedroom townhome, including shipping, installation, mechanical systems, and appliances, could be sold to a developer for about $258,000 per unit.
ZETA doesnâ€™t just sell to developers, theyâ€™ll work with colleges, cities, public agencies, and hospitals, etc.Â Weâ€™ll keep our eyes on the company and see where new projects pop up.
