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.
- 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.
- 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.
