Since 2015, all construction and renovation projects in the Brussels-Capital Region must comply with passive standards. Passive buildings are energy-efficient and comfortable: a first step towards the city of the future.
Passive construction
In financial terms, you will have to dig a little deeper into your pockets during the construction work, although energy subsidies are available.
A passive house costs around 10% more than a traditional house. However, it is an investment that more than pays for itself in the long run.
- The energy bill is much lower: a passive building requires 5 to 8 times less energy for heating than a conventional home.
- Comfort is increased.
- The sale value increases.
Passive renovation
Renovating an existing home to passive standards is possible, but it is complex.
It is, of course, possible to apply the same principles (insulation, airtightness, ventilation) throughout, but a good plan is an absolute must, especially for those renovating in phases. Therefore, seek guidance from an advisor, such as an architect.
Even if you opt for passive renovation, the investment is definitely worthwhile.
Did you know that the power of an iron - around 2000 W - is enough to heat a passive house in Doornsee on cold days? A small radiator in the living room or bathroom is sufficient. For the rest of the year, such a house requires hardly any heating.
