HOW MUCH DOES A PASSIVE HOUSE COST? As expected, it is more expensive to build a passive house than a conventional house. Extra construction cost is likely to be 10% to 15% more, but savings on utility bills completely offset this after just few years.
How much does a Passive House cost per square foot?

How do you buy a Passive House?
These principles, which we’ll elaborate on shortly, include:
- An airtight building envelope.
- A ventilation system that balances heat and moisture management.
- High-performance windows and doors.
- Continuous insulation throughout the envelope, with no thermal bridging.
- A minimal space conditioning system.
What are the three requirements for a home to be Passive House certified?
The Passive House Standard stands for quality, comfort and energy efficiency.
Are passive homes worth it?
Ultimately it shows that the air in a Passive House is far fresher, drier and healthier, and the building is far more efficient.” Like airtightness, thermal bridging is to do with a building’s energy loss.
What qualifies as a passive house?
The exact definition is as follows: “A Passive House is a building, for which thermal comfort (ISO 7730) can be achieved solely by post-heating or post-cooling of the fresh air mass, which is required to achieve sufficient indoor air quality conditions – without the need for additional recirculation of air.”
Is Passive House expensive?
The study by Encraft’s Building Physics Team shows that whole life costs of houses built to Passivhaus standards can be 2-5% lower than traditional construction methods, even accounting for slightly higher build costs.
How much money do passive houses save?
Are Passive Houses a good investment? Absolutely, with an 80 – 90% reduction in annual heating/cooling fuel consumption the energy savings will cancel out much of the increased up-front investment cost of increased insulation, better-quality windows and ventilation systems.

- No thermal bridging.
- Superior windows.
- Mechanical ventilation with heat recovery.
- Quality insulation.
- Airtight construction.
What are the disadvantages of a Passive House?
The main disadvantage to building a passive house is the upfront cost. Industry leaders generally agree that the cost of building a passive house is ten percent higher than building a house that simply meets local code requirements.
