The Benefits of a Passive House
Passive House is not just a building standard — it is a fundamental rethinking of how a home should work.
Up to 90% Energy Savings
1. Up to 90% Energy Savings
The Passive House standard is the most rigorous energy-efficiency building standard in the world. By combining super-insulation, elimination of thermal bridging, and a near-airtight envelope, a certified Passive House uses up to 90% less heating and cooling energy than a conventionally built home.
Exceptional Year-Round Comfort
2. Exceptional Year-Round Comfort
Traditional homes have hot spots near windows, cold drafts along exterior walls, and temperature swings between floors. A Passive House eliminates all of that. Its continuous insulation layer and triple-pane windows keep every surface uniformly warm in winter and cool in summer.
Superior Indoor Air Quality
3. Superior Indoor Air Quality
A Passive House is not just sealed — it breathes deliberately. The Energy Recovery Ventilator (ERV) continuously exchanges stale, CO₂-rich indoor air with fresh outdoor air, recovering over 80% of the heat in the process.
Drastically Reduced Carbon Footprint
4. Drastically Reduced Carbon Footprint
Buildings are responsible for nearly 40% of global CO₂ emissions. A Passive House's minimal energy demand means it produces a fraction of the operational carbon of a standard home.
Built to Last — Exceptional Durability
5. Built to Last — Exceptional Durability
The meticulous construction quality demanded by Passive House certification produces a structurally superior building. Continuous vapor management prevents the moisture accumulation that leads to rot and mold in conventional homes.
Acoustic Comfort
6. Acoustic Comfort
The same thick insulation envelope and triple-pane windows that keep heat in also block sound out. Street noise, aircraft, and neighbors are muffled to near-silence inside a Passive House.
Resilience During Power Outages
7. Resilience During Power Outages
Because a Passive House retains heat so effectively, its interior temperature changes only very slowly when the power goes out — typically less than 1–2°F over a 24-hour period.
The Perfect Foundation for Electrification
8. The Perfect Foundation for Electrification
Passive House is the ideal starting point for a fully electrified, sustainable lifestyle. Because the heating and cooling load is reduced by up to 90%, a small, affordable air-source heat pump can handle all space conditioning.
What Does Passive House Certification Mean?
- Heating & Cooling Demand: No more than 15 kWh/m²/year.
- Airtightness: No more than 0.6 ACH50, verified by a blower door test.
- Primary Energy: Total primary energy use capped at 120 kWh/m²/year (PHIUS).
- Thermal Comfort: No more than 10% of occupied hours may exceed 77°F (25°C) in summer.
