Performance: Certified Passive House Classic

Airtightness: 0.38

Heating demand: 13.9kWh/(m²a)

Cooling demand: 7.0kWh/(m²a)

Frequency of overheating: less than 11% (when not using AC for cooling).

Frequency of excessive humidity: 0%

The total solar energy required for the house is 8,300 kWh per year, which calculates to roughly 692 kWh per month. This is a calculated average based on assumed usage. The energy demand will be different in reality based on outside factors (temperature, daylight etc.) and indoor factors (electricity use of services, appliances, electronics etc.).

With a 12,175 kWh solar PV system the house will generate sufficient energy throughout the year to supply the required electricity demand, without the need for the grid or batteries (Passive House doesn’t account for battery storage yet). This translates to 25x 350W PV panels. The calculation doesn’t take into account Electrical Vehicle charging.
