Passive House

 

PRINCIPLES OF PASSIVE HOUSE

Solar Orientation

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.

Insulation

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.

Benefits of Passive house includes:

  • Better indoor air quality
  • Increased thermal comfort
  • Superior sound insulation
  • Highest level of energy efficiency
  • Reduced energy bills
  • Reduce carbon footprint
