Does it cost more to build a Passivhaus?
Building to the Passivhaus energy efficiency standard enables you to create a cosy and comfortable home, while cutting heating bills by around 76%, compared to current building standards. This figure is based on the Passivhaus standard space heating requirement of 15kWh/m²/a, compared with current UK Building Regulations which are modelled as delivering 63kWh/m²/a (factoring in a conservative estimate of a 40% performance gap).
