Zeta-front-door Zeta-deck

Prefab multifamily is the new black these days, which is why we’ve been watching startup ZETA Communities with interest.  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.  The townhomes achieved LEED Platinum certification, a 240 green point rating, and an EPA Indoor airPLUS, the EPA’s highest indoor air rating.  Each home is 1,540 square feet with two bedrooms and a single-car garage.  And they’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.  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 doesn’t just sell to developers, they’ll work with colleges, cities, public agencies, and hospitals, etc.  We’ll keep our eyes on the company and see where new projects pop up.
