What is a “Passive House”?

A certified “passive” house is a house complying with four specific criteria:

  • heating requirement ≤ 15kWh/m².yr
  • airtightness ≤ 0,6 h-1
  • over-heating percentage ≤ 5%
  • primary energy consumption ≤ 45 kWh/m².yr

More simply said…

A passive house requires approx. 1/4 the energy necessary to heat a standard new building.
Due to state-of-the-art airtightness and insulation level, the energy requirement for the heating system is approx. 1.5 liters of fuel per square meter with no overheating in the summer period.
A mechanical ventilation system with heating recovery ensures the intake of fresh air.
