Brief simple intro to Passivhaus

1. Passivhaus building technology for a sustainable future

2. 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

3. 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

8. Passivhaus and . . .

9. Passivhaus basics Insulation optimization with air-tight construction & no thermal bridges Balanced - constant, low velocity, 100% fresh air, with high efficiency heat exchange passive heating in heating season, with heat gain controlled by shading in cooling season Balanced Integrated design and PHPP: the passive house planning process passive,

10. Passivhaus basics If it’s not certified, it’s not a Passive House Building design planned with a Certified Passive House Consultant Design verified by PHIUS Construction air-tightness verified Post occupancy verification

11. Passivhaus costs It depends!

12. Passivhaus why ?

13. 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.
