• Buildings at the leading edge of sustainability

Extraordinary performance, affordable cost.

A Passive House 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.  In fact, Passive House buildings' beauty rival that of any other project: see the Karuna House.

Passive House buildings offer practical, local  solutions to big, global energy problems.  But even more important, they're the most comfortable, peaceful, and healthy living spaces available anywhere.

To achieve this, the Passive House building standard employs 7 principles:
  
   1. superinsulate.
   2. eliminate "thermal bridges".
   3. build airtight.
   4. ventilate with energy recovery.
   5. use good windows & doors.
   6. optimize solar & heat gains.
   7. model with advanced software.

The result?  All heating needs in a typical Passive House can be met by a single 1000-watt heater.  Heat from people, lights, appliances and the sun does the rest.  Our Certified Passive House Consultants can optimize the right design for you.
