Passivhaus design takes the fresh air, natural light, and peace and quiet of nature and brings it inside.

Health & Happiness

Natural daylighting reduces the need for artificial lighting. Heat from the sun reduces the need for active heating. Filtered fresh air ventilation, combined with an advanced building envelope free of air leaks, creates healthy indoor air quality that is proven to improve the respiratory health of building occupants.

According to the US Department of Energy, Passivhaus buildings are dramatically superior to both ENERGY STAR® and conventional buildings in measures of health, comfort, energy efficiency, and durability.

The comfort of Passivhaus buildings is both thermal and acoustic, delivered by the same robust insulation and high-performance windows that make them so energy efficient. Because the human body is such a sensitive sensor of radiant temperature, the uneven surface temperatures found inside conventional buildings–even when air temperature is at 72°– make occupants either too cold or too hot. The thick and uninterrupted thermal blanket of Passivhaus buildings guarantees even surface and air temperatures. It also creates an unbroken barrier to outside noise, reducing that noise by half or more for building occupants.

Filtered fresh air, comfort, and quiet all appeal to urban buyers and tenants.

The air inside the house feels so fresh, you can almost taste its sweetness.”

Passivhaus

Passivhaus design optimizes the light, air, and thermal energy of a building, reducing building energy use by as much as 75%. It’s the world’s most rigorous building energy standard, charting a straight path to zero carbon building. The result is a better way to design and build, with revolutionary performance and predictable results.
