Impact of the relaxation on sales and energy efficiency
The proposed relaxation means that homes with fossil-free heating could meet label C, entailing lower renovation costs for sellers. According to energy specialist Ruben Baetens of the Institute for Energy & Society at KU Leuven, a house can even achieve label C just by installing solar panels and a heat pump, with no insulation required. This may seem advantageous for owners who want to sell their homes, as these houses would have to meet fewer renovation obligations, increasing their value. However, the relaxation also carries risks: homes may appear more energy efficient on paper, while in reality they continue to generate high heating costs due to lack of insulation.
