Key Principles of Passive House

Passive House 101

Efficiency at its best

No matter the climate or region, Passive Houses stay at a comfortable temperature year-round with minimal energy input. These buildings make efficient use of the sun, internal heat sources and heat recovery for their heat, rendering conventional heating systems unnecessary throughout even the coldest of winters.

Sustainability: A Passive House uses up to 90% less energy than a typical US building

Affordability: As seen from the entire building lifecycle, Passive Houses save money and are surprisingly affordable to build

Comfort: Passive houses pair pleasant temperatures with extremely low energy use.

Sustainable Affordability

Passive Houses do not require conventional heating or cooling units, meaning that investment can instead be channeled toward higher-quality components. This, in addition to vast, long-term energy savings make Passive House an excellent investment. Especially in the face of dwindling energy resources and rising energy costs, the Passive House Standard exemplifies sustainable affordability.

1. Thermal Insulation

A well-insulated building envelope keeps warmth in during the cold months and heat out during the warmer months.

2. Passive House Windows

Strategically positioned, highly insulated windows do their part to make optimal use of the sun's energy

3. Ventilation with Heat Recovery

Passive House ventilation systems provide plentiful fresh, pollen and dust-free air with maximum energy efficiency through heat recovery.

4. Air Tightness

Passive Houses are designed to avoid leakages in the building envelope, thus boosting energy efficiency while preventing drafts and moisture damage.

5. Thermal Bridge-Free Design

Avoidance of thermal bridges (weak points in the building envelope) contributes to pleasant, even temperatures while eliminating moisture damage and improving energy efficiency.
