* Estimated savings compare Passivhaus standard (15 kWh/m²/year) against a new conventional build (112 kWh/m²/year, EU average for new residential construction). Calculation uses €0.40/kWh average EU energy price with a 25% conservative adjustment for real-world conditions. Actual savings vary based on climate, energy prices, and usage patterns.

How this calculator works
How it works
This energy savings calculator uses data from European building performance studies, internal tests, Passivhaus Darmstadt simulations, and real-world projects to give you an approximation of what you could save. With the average expected energy demand for heating and cooling (which take up ~80% of energy demand) being ~90–96%, that is highly significant.
What affects your results
Every building is unique. Your specific savings will depend on factors like your local climate, how your house faces the sun, your family’s lifestyle, and local energy costs. Think of these numbers as a helpful starting point for understanding the difference between conventional and passive house performance.
Our recommendation
Use these estimates as a starting point to explore the potential of passive house design. This tool is designed for educational and planning purposes. While we’ve worked hard to make it as accurate and useful as possible, actual building performance varies, and these figures are not a guarantee of what your specific project will achieve. The final savings might be higher or lower.

COSTS & SAVINGS
A Passivhaus-certified home uses a maximum of 15 kWh/m² per year for heating, compared to 120-200 kWh/m² for a conventional home. This translates to energy bill reductions of up to 90-96%, depending on your climate zone and local energy prices.
Over 30 years, this can amount to tens of thousands of euros in savings, effectively paying for the home's premium many times over.
See how Passivhaus certification achieves this.A Passivhaus home typically costs around 20% more than a standard new build. However, BIOBUILDS modular construction brings this premium significantly lower through factory efficiency and EU-wide bulk material sourcing.
When you factor in the dramatically lower operating costs from day one, the total cost of ownership over 10-15 years is often lower than a conventional home.
Explore our catalog for current pricing.Most BIOBUILDS homeowners see a payback period of 5-8 years, depending on local energy prices and the size of their home. In countries with higher energy costs, the payback can be even faster.
After the payback period, the savings continue for the lifetime of the home, which is designed to last 80+ years with minimal maintenance.
Configure your home and see your projected savings.THE INVESTMENT
Typical heating and cooling costs for a BIOBUILDS home range from 100-300 euros per year, depending on the model size and your climate zone. Compare this to 2,000-4,000 euros per year for a conventional home of similar size.
These figures are based on real-world data from delivered BIOBUILDS projects and Passivhaus Institut simulations.
See real projects and their performance data.Many European countries offer significant incentives for energy-efficient construction, including reduced VAT, green mortgage rates, direct subsidies, and tax deductions. Passivhaus certification often qualifies for the highest tier of incentives.
BIOBUILDS can help you navigate the incentive landscape in your country. The savings from incentives can further reduce the effective cost of your home by 10-30%.
