Passive House Construction
Extraordinary performance.
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 rivals that of any other project: see the Karuna House and the Pumpkin Ridge Passive 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 or working spaces available anywhere. See the Glasswood Commercial Passive House Retrofit and Ballard Passive House.
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 heater the size of a hair dryer. Heat from people, lights, appliances and the sun does the rest. Our Certified Passive House Consultants can optimize the right design for you and your Portland or Seattle Passive House.
