Benefits of Passive House Buildings

"Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input" – International Energy Agency

Passive House buildings are designed and constructed to be highly energy efficient, they have the potential to use up to 90% less energy than the current building stock, whilst performing the same (if not better) functions as traditional buildings. A Passive House window for example can reduce heat losses by more than 70% compared to existing double glazed windows. High quality external insulation added to a wall can reduce heat losses by 90% and an efficient heat recovery system can reduce ventilation heat losses by up to 90%. This means very little additional heating/cooling will be required to maintain comfortable indoor temperatures. What’s more, the vigourous planning procedures and calculations performed by the Passive House Planning Package (PHPP) ensures there is no performance gap between the expected and actual building performance.

So what does this mean for the end user? Simply put, fuel bills will be significantly lower because of the reduced energy consumption, saving residents money, helping to alleviate fuel poverty and improving peoples lives. In addition, with space heating/cooling of buildings responsible for almost half of all fuel consumption, large scale application of the Passive House Standard is a huge opportunity to reduce CO2 emissions, create new jobs and boost the economy. The more buildings retrofitted or constructed to the Passive House Standard, the more significant the savings.
