Yes! Passivhaus principles can be applied to both contemporary and traditional architectural styles, ensuring that your home blends seamlessly with its surroundings or suits your aesthetic preferences.
While initial costs can be higher, the long term savings on energy bills and the reduced environmental impact make it a worthwhile investment. The design has to be meticulous and the construction high quality – combined, creating a more resilient building. If you are keen on the Passivhaus methodology, but the cost becomes problematic, the AECB offer an excellent alternative standard. We are also AECB certifiers and would be pleased to discuss this alternative!
