What is a Passive Home?

More than just a home with energy efficient products and solar panels, a Passive House is actually the world’s leading standard in energy efficient construction—providing up to 80% savings on energy compared to standard new builds! Passive Houses have become popular in Europe over the past 25 years and are a growing concept for construction in the U.S. A Passive House is a cost-efficient, high quality, healthy, and sustainable option for new homes. In a nutshell, building a Passive House can give you comfort, healthy indoor air quality, and reduced energy costs. To top it off, they are also affordable to build.

Passive Houses feature the following superior design components:

  • Energy reduction
  • Insulation
  • Air tightness
  • Ventilation with heat recovery
  • Design avoiding thermal bridges
  • Highly efficient windows
  • Innovative heating technology
  • Energy balance
  • Solar orientation
  • Mold reduction

With rising energy costs and a growing awareness of indoor pollutants and environmental hazards, the time for Passive Home builds to be considered has come.
