Each Passive home built utilizes site specific annual weather data in orienting the home for maximum solar heat gain in Winter and solar shading in Summer.
Wall assemblies are designed to be air tight and have high insulation values to keep the conditioned air from leaking. But, beyond air movement, Passive home wall, roof, and foundation assemblies are designed to manage moisture levels for building longevity and durability.
High Performance Windows
Windows and doors are often the area in which we feel the most draft and are the weakest link in energy efficiency. Passive design specifies super high performance windows that must meet strict standards for component insulation, air tightness installation, and solar heat gain values.
Balanced Ventilation & Heat Recovery
Passive House mechanics include an energy recovery ventilator or the “lungs” of the house, that provides a constant supply of tempered, filtered, fresh air 24/7 and saves money by recycling the indoor energy. The heat from outgoing stale air is transferred to the unconditioned incoming fresh air. Filtering adds an extra layer of comfort, particularly for those with allergies.
