Passivhaus building technology for a sustainable future
Passivhaus Defined Passivhaus is an integrated design system. Defined and verifiable parameters Passive House Requirements: Annual Heating/Cooling Energy Demand (per net floor area): ≤ 15 kWh/(m2a) - ≤4750 Btu/ft2 Annual Total Primary Energy Demand (per net floor area): ≤ 120 kWh/m2 - ≤11.1 kWh/ft2 Air Leakage @ 50 Pa n50≤0.6 ACH - n50≤0.1 CFM
Passivhaus Advantages 100% outside air with MERV13 filtration min 64°F surface temp = comfort Thermal bridge free construction eliminates condensation No MOLD! Bathed in natural light Quantum leap in energy efficiency Rigorous quality control and verification Zero energy achieved with minimal expense

Building energy use is a major contributor to the climate change energy emergency. Passive House is the most rigorous approach tackling this predicament and certifying it.
