Explore the principles of Passive House design for energy-efficient homes that offer comfort, lower utility bills, and improved air quality.
Passive House Design Explained Passive House design is a way to build homes that use much less energy while staying comfortable all year. It focuses on five key principles: - Superinsulation: Thick insulation keeps homes warm in winter and cool in summer. - Airtight Construction: Sealing gaps and cracks prevents energy loss. - High-Performance Windows/Doors: Advanced materials reduce heat loss and drafts. - Thermal Bridge-Free Design: Eliminates weak spots where heat escapes. - Ventilation with Heat Recovery (HRV/ERV): Maintains fresh air while saving energy. These homes lower utility bills, improve air quality, and reduce reliance on heating and cooling systems.
