Frequently Asked Questions
What is the typical cost premium for a Passive House?
In experienced markets, the premium for a new Passive House build is typically 5-15% above standard construction. Retrofits carry higher premiums due to the complexity of airtightness upgrades.
How does Passive House compare to LEED or ENERGY STAR?
Passive House is an outcome-based standard with mandatory energy intensity limits verified by independent certification. For occupants concerned with operating costs and comfort, it is generally a stronger predictor of real-world energy performance.
Are there health benefits beyond energy savings?
Yes. Occupants consistently report more stable temperatures, no cold drafts, quieter interiors, and better indoor air quality from continuous filtered ventilation.
Can an existing home be retrofitted to Passive House standard?
Yes, though it is more complex and costly than building new. EnerPHit is a slightly relaxed standard specifically designed for existing building retrofits.
