Learn how to create an energy-efficient passive house by following key principles and practical steps for design and construction.

How to Build A Passive House Building a passive house means creating an energy-efficient home that requires minimal heating and cooling. It’s based on five key principles: airtight construction, superior insulation, thermal bridge-free design, high-performance windows, and balanced ventilation with heat recovery. This approach, originating in Germany, reduces energy use by up to 90% compared to standard homes. Key Benefits: - Energy Savings: Annual heating costs as low as $100–$300 for a 2,000 sq. ft. home. - Comfort: Consistent indoor temperatures with no drafts or hotspots. - Healthier Air: Continuous ventilation filters out pollutants and allergens. - Eco-Friendly: Cuts carbon emissions by 60–80%. Building Essentials: 1. Airtight Envelope: Prevents air leaks (0.6 ACH50 standard). 2. High Insulation: Walls (R-40 to R-60), roofs (R-60 to R-80). 3. Triple-Pane Windows: U-value ≤ 0.15 Btu/hr-ft²-°F. 4. Ventilation: HRVs or ERVs ensure fresh, clean air while conserving heat. 5. Thermal B...
