A passive house is an extremely energy-efficient building designed to minimize heat loss and achieve a comfortable indoor temperature throughout the year with minimal energy consumption.
This is achieved through a combination of architectural elements, efficient heating and cooling systems, and high-performance construction materials.
Principles of a Passive House:
Extremely good insulation: Walls, ceilings, floors, and windows are very well insulated to reduce heat loss in winter and heat gain in summer.
Windows with thermal glazing: Windows are large and allow natural light to penetrate the interior, but they are equipped with glass with very good thermal performance.
Optimal orientation: The house is oriented to maximize solar gain in winter and be protected from the sun in summer.
Mechanical ventilation with heat recovery: A ventilation system ensures fresh air indoors while simultaneously recovering heat from the exhaust air.
Airtightness: The house is very well sealed to prevent air infiltration and reduce heat loss.
Benefits of a Passive House:
High thermal comfort: The indoor temperature is constant and pleasant throughout the year.
Significant savings on energy bills: Energy consumption for heating and cooling is reduced by up to 90% compared to a conventional building.
Improved indoor air quality: The ventilation system ensures fresh and healthy air indoors.
