WHAT IS A “PASSIVE HOUSE”?
A certified “passive” house is a house is a house that has been certified as a “passive house” and 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 house built 10 years ago.
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.
IS A PASSIVE RENOVATION ALWAYS POSSIBLE?
Unfortunately, no! For various reasons, some houses or apartments cannot achieve the passive label. However, most energy renovations manage to meet the PEB requirements planned for 2045 (in Brussels, PEB C+ max 130 kWh/m²/year).
