East Bay General Contractor Mara Construction Partners with Net Zero Homes on ‘Passive Home’ Building Projects

Orinda, California (EastBayDaily) — Mara Construction, a general contractor in the East Bay, is partnering with architect, James P. Wright of Net Zero Homes on a new building project called “Passive Homes.”

Passive House is today’s leading standard for energy efficient construction with the promise of reducing the energy consumption of buildings by up to 85 percent while providing superior comfort and air quality–all at minimal additional upfront cost. When coupled with renewable energy systems, such as solar energy, a Passive Home puts true net-zero energy homes within reach.

The U.S. Department of Energy defines a Net-Zero energy home as one that uses about 60 to 70 percent less energy than a conventional home, with the balance of its energy needs supplied by renewable technologies. Essentially, it is a home that sustains itself.

A Passive Home is an ultra efficient building standard that saves up to 85 percent on space heating and cooling. It is fast becoming the leading energy efficiency and comfort standard for all building types across the world. This 20-year-old concept has been achieved in more than 20,000 projects, from multi-family units to assisted living facilities and low-income housing to condo developments and commercial properties to schools and houses.

Passive Home buildings offer practical, local solutions to big, global energy problems. But even more important, they're the most comfortable, peaceful and healthy living or working spaces available anywhere. It combines straight-forward building technologies with advanced building modeling to achieve revolutionary energy efficiency, and it does so without relying on expensive gadgetry or strange building design.

The structure is a super insulated, virtually air-tight building that is primarily heated by internal gains from people, electrical equipment and by passive solar gains through windows and doors. Any remaining heating and cooling demand is provided by an extremely small, split heat pump. Fresh air is provided by an ERV (energy recovery ventilator) system. ERVs provide fresh air while recovering the exiting conditioned air at approximately 85-percent efficiency. With the addition of a properly sized small solar array, the home can easily reach the level of net zero. The end result is a comfortable, energy bill free building that has excellent indoor air quality.

Passive House’ benefits include affordability, no energy bills/net zero, increased comfort, excellent air quality, less exterior noise, carbon neutral living and environmental friendliness.
