What is a Passive House?

A Passive House is a comprehensive design and construction system which lowers energy consumption by up to 85%. “Passive House” refers to the extremely energy efficient nature of the homes and its minimal impact on the environment. It is currently the highest performance standard for homes in the world. Here are some of the many features that make a Passive House:

  • Virtually air-tight construction and superior insulation maintain habitable interior temperatures in freezing or very hot weather, even without power, for long periods of time.
  • Shading and window orientation, and with high performance windows, avoids excessive heat gains and losses, and further limits cooling.
  • An integrated design and energy modeling approach, provides predictability—an essential tool in optimizing mechanical system performance and providing more comfort.
  • Advanced air filtration and exhaust systems removes indoor air contaminants and maintain fresh interior air 24 hrs a day.
  • High performance construction materials reduce the need for a large HVAC system, thereby reducing your “active” energy consumption and lowering your monthly energy bills.
  • Net-Zero is a simple upgrade with rooftop photovoltaic solar panels, because of the already low energy loads.
