When floors, walls and installations are open anyway, making a home sustainable is relatively simple and cost-effective. The order matters.
The building envelope first
Insulating the roof, facade and floor and high-performance glazing reduce the heat demand. Only then can the installation be sized correctly.
Then the installation
A heat pump works best with low-temperature heating, such as underfloor heating. Good ventilation — for example balanced ventilation with heat recovery — belongs to a well-insulated home.
Subsidies and financing
There are schemes for insulation and heat pumps, among others. Conditions and amounts change regularly; always check the latest information with RVO.
Comfort as a result
Sustainability is not only about energy. An even temperature, no draughts and a healthy indoor climate make the difference in daily living.
