* Estimated savings compare Passivhaus standard (15 kWh/m²/year) against the EU new-build average (112 kWh/m²/year). Calculation uses €0.40/kWh average EU energy price with a 25 percent conservative real-world adjustment. Actual savings vary by climate, glazing ratio, energy prices, and occupant behavior.

How this calculator works
Methodology
This tool compares Passivhaus standard (15 kWh/m² per year for heating and cooling, per Passive House Institute) against the EU new-build average (112 kWh/m² per year, per Building Stock Observatory). Energy price uses the EU average of €0.40/kWh. A 25% conservative real-world adjustment is applied to account for occupant behavior and climate variance.
What affects your results
Every building is unique. Actual savings depend on your local climate, building orientation, glazing ratio, occupant lifestyle, and local energy tariffs. Treat the output as a planning-grade estimate, not a binding figure.
Recommended use
Use this calculator to compare construction options, evaluate Passivhaus payback, and benchmark the operational cost difference between a conventional build and a certified Passivhaus. The output is informational and does not constitute a financial guarantee.
Questions about Passivhaus ROI
ENERGY & COSTS
A Passivhaus certified building uses approximately 15 kWh/m² per year for heating and cooling, compared to 112 kWh/m² for the average EU new build (Building Stock Observatory 2023). That is an 87 percent reduction in operational heating and cooling energy.
Over 30 years and based on €0.40/kWh average EU energy price, a 150 m² Passivhaus saves roughly €130,000 in heating and cooling costs versus an equivalent conventional new build.
Read the Passivhaus standard explained.Passivhaus construction typically adds 5 to 15 percent to upfront build cost compared to a conventional EU new build, driven by triple glazing, MVHR ventilation, airtightness work, and continuous insulation.
Modular and prefab construction methods can offset much of this premium through factory efficiency, often making certified Passivhaus comparable to a conventional onsite build of the same size.
Compare construction options.INVESTMENT & PAYBACK
Many European countries offer incentives for energy-efficient construction, including reduced VAT, green mortgage rates, direct subsidies, and tax deductions. Passivhaus certification typically qualifies for the highest tier of these incentives.
Incentive value commonly reduces the effective construction cost by 10 to 30 percent. Specifics depend on country and year, contact a local Passivhaus consultant for current figures.
