Studies such as the U.

It might sound too good to be true, but these pleasant conditions are the norm for people who live in a Passive House. A Passive House conserves energy by creating a virtually air-tight, super insulated, compact building enclosure that uses the sun and heat emanating from people and equipment to achieve a comfortable indoor environment.

A ventilation system including what is called a heat recovery ventilator or HRV is used to provide a continuous supply of filtered fresh air. Added all together, Passive House offers a triple bottom line: A Passive House project maximizes the energy efficiency of the basic components inherent in all buildings: Unlike any other structures, Passive House buildings maintain occupant comfort for more hours of the year without relying on active heating and air-conditioning equipment.

Interior View of the Keffer Passive House With a history of inexpensive fuel and undisciplined construction techniques, there has been little need to consider the impact of energy losses through poorly engineered building enclosure s.

Typical construction is plagued with low levels of insulation, high air infiltration, and thermal bridging between interior and exterior.

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. In a Passive Housea 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. There is simply no need for a large, conventional, expensive, resource guzzling heating and cooling system. Superior sound insulation Extraordinary airtightness levels, triple-pane glass, and thick insulation also provide superior sound insulation.

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

Resilient 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.In February , GSA announced its plan to renovate the 92 year-old Wayne Aspinall Federal Building and U.S.

Courthouse and make it the country's first Net Zero site energy historic building. Passive House is the most rigorous and effective energy standard in the world. We know how to do it. Design, construction, performance, and cost information on our Zero Energy House project in Auckland, New Zealand.
