* Estimated savings compare Passivhaus standard (15 kWh/m²/year) against the EU new-build average (~150 kWh/m²/year). Calculation uses €0.29/kWh EU household electricity (Eurostat H2 2025, published May 2026) with a 25 percent conservative real-world adjustment. Actual savings vary by climate, glazing ratio, energy prices, and occupant behavior. Sources: Passive House Institute, EU Building Stock Observatory, Eurostat.
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 (~150 kWh/m² per year, per Passive House Institute country surveys and EU Building Stock Observatory). Energy price uses the EU household electricity average of €0.29/kWh (Eurostat H2 2025, published May 2026). 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. Compare models in the catalog or price yours in the configurator.
Questions about Passivhaus ROI
ENERGY & COSTS
The Passivhaus heating-demand benchmark is 15 kWh/m² per year. Against the 150 kWh/m² annual heating-demand reference used in this comparison, that is a 90% reduction in heat needed for space heating.
Bill savings also depend on the heating system’s efficiency and energy tariff. The calculator shows an estimate for the assumptions selected; it is not a guaranteed saving.
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
Some countries offer loans, grants or tax measures for energy-efficient construction. Eligibility depends on the specific programme and project; Passivhaus certification alone does not secure funding.
For Germany’s KfW 297/298 programme, the highest loan ceiling requires QNG eligibility. An energy-efficiency expert must assess the project, and current programme conditions apply.
