Overview

Passive House

Passive House is the world’s most rigorous standard for building energy efficiency, comfort and air quality. Building to this standard can slash energy consumption by as much as 90%. Widespread implementation would make a significant contribution to the fight against global climate change.

 

NOFOSSILFUELSWhat Makes a Building a “Passive House”?

  • It is Super-Insulated. This reduces heating and cooling demand and eliminates the cold surfaces where moisture condenses and mold flourishes.
  • It is Virtually Air-Tight. This reduces drafts and energy consumption; it also prevents moist indoor air from penetrating the building envelope, which can cause premature decay and mold growth.
  • It is “Thermal Bridge” Free. Thermal bridges are pathways for energy loss created by conductive materials in the building envelope. Eliminating thermal bridges saves energy and inhibits mold growth.
  • It is Heated Mainly by the Sun & Building Occupants & Equipment. Technologically advanced windows allow the sun’s heat (and light) in, while the insulation keeps it there.
  • It has a Continuous Supply of Fresh Air. A high-efficiency heat recovery ventilator replaces stale indoor air with fresh outside air, with minimal effect on the interior temperature.

Why Build a Passive House?

  • Sustainable. Reduced consumption of fossil fuels means fewer greenhouse gases.Passive House vs Typical
  • Comfortable. Superior indoor air quality – no cold spots or drafts.
  • Affordable. Dramatically reduced heating and cooling costs.
  • Versatile. Any building type; new or retrofit; modern or traditional.
