Increased thermal comfort

Passive House offers the highest level of interior comfort of any building type today with comfortable temperatures, no drafts or cold spots, and no temperature swings.

Almost unbelievable energy efficiency

Passive House buildings consistently reduce energy for heating and cooling by 80 to 90% over typical construction. There is simply no need for a large, conventional, expensive, resource guzzling heating and cooling system.

Durability

Careful detailing, advanced design, better building components, and proven building science help to ensure there is no mold and no condensation inside the home or inside the walls of the home. Passive House buildings are designed to last a long time.

Resilience

Because a Passive House very seldom requires active systems for heating and cooling, comfortable indoor conditions are maintained even during power outages or in the face of fuel shortages.

Path to Net Zero

The low energy required by a Passive House for heating and cooling means that a small and affordable renewable energy system can turn a Passive House into a Net Zero (glossary link) energy building.

Superior sound insulation

Extraordinary airtightness levels, triple-pane glass, and thick insulation also provide superior sound insulation. Passive Houses are very quiet.

Much improved indoor air quality

We spend 90% of our time indoors where the air quality is typically 3 to 4 times worse than it is outside. In a Passive House, a continuous supply of filtered fresh air is provided by the ventilation unit which also transfers the thermal energy from the air leaving the house to the fresh air coming into the house, greatly reducing the need for heating and cooling. The result is comfortable, fresh indoor air with greatly reduced dust, pollen, and other pollutants.

Low maintenance

With simple mechanical systems and high quality care-free building components, Passive House buildings are simple to operate and inexpensive to maintain.

Affordability

The initial cost of a Passive House building is approximately 0% to 10% more than typical construction. However, the high quality construction reduces monthly heating and cooling costs by 80% to 90%.

Measured and verified performance

Computer energy modeling of a home’s energy consumption during the design stage and third party verification during the construction stage provide assurance of a superior building.
