Not necessarily. It’s important to understand that ‘Passive House’ is a concept rather than a construction method, which means it can be adapted to any type of building. As long as the project is thought out from the beginning in a holistic way, building a Passive House can have a similar or even lower cost than a conventional building. It’s essential to consider all the calculations… Passive House buildings require about 90% less heating energy than conventional buildings, which means significant annual savings. So, don’t forget to do all the calculations, both for construction and maintenance costs.
