Passive House Savings Calculator

Find the heating demand of a passive house compared with a standard one.

Floor area (m2)

Standard heating demand (kWh/m2)

Passive house demand (kWh/m2)

Energy price ($/kWh)

Annual savings 1,890

Energy reduction (%) 87.5

Formula: savings = area * (standard - passive) * price

Step-by-step with your numbers:

1. Values used:

2. Floor area = 120 m2

3. Standard heating demand = 120 kWh/m2

4. Passive house demand = 15 kWh/m2

5. Energy price = 0.15 $/kWh

7. Annual savings = 1,890

8. Energy reduction = 87.5%

Did we solve your problem today?

Passive houses need dramatically less energy for heating than standard buildings.

The math behind it

savings = floor area x (standard - passive demand) x energy price.

A 120 m2 passive house at 15 kWh/m2 saves about $1890/year vs 120 kWh/m2 (87% reduction).

What is the passive house standard?

A design that keeps heating demand below 15 kWh/m^2/year through super-insulation and airtightness.
