You’re probably on our website for one reason and one reason only — to learn how to get your new build (or maybe your extension) to pass its SAP calculation or airtightness test. The regulations can be confusing and the calculations even more so, but we can guide you through the process so your build passes and can go on the market (or be lived in). But did you ever stop to think about why SAP calculations exist? Why are they a must-have, rather than a nice-to-have? How much damage can an inefficient building actually cause? Read on.
Airtightness tests exist because of the extreme tightening of CO2 emissions targets, driven by UK and EU climate policies. These are also the policies which are making SAP calculations harder and harder to pass as time goes on, and why articles like this can be so helpful. Such policies exist for the sake of our ozone layer, our polar ice-caps and our species.
It might be hard to conceptualise how air leaking from gaps in the walls or dwellings from Darren’s house can have an effect on warming the whole planet, but it does. There are lots of Darrens out there, and billions more inefficient houses. Put them together and the effect is more-than-considerable.
It’s a bitterly cold winter’s day and you’ve cracked the heating on. Unfortunately for you, there are also plenty of cracks in your building envelope, most of which you can’t even see.
It’s roasting. It’s the middle of summer and the humidity is through the roof. So, you crack the air-con on. Unfortunately for you, there are also plenty of cracks in your building envelope, most of which you can’t even see.
Both of these situations have the same result: you lose money — a lot faster than you might think.
Setting an Example
So, being environmentally and economically sensible goes hand in hand with efficient houses and is why the tests exist. To reiterate the importance of all of this, it’s good to look into the future and think about our grandchildren, their children, and their children’s children. Setting an example for them on how to be so sensible, with the environment particularly, is crucial. We’re the first generation or two that has had to deal with these tests and regulations. While they might be a pain and an extra headache you didn’t need, they’re here for a reason and it’s our responsibility to do them properly. If we do, our descendants will. If the chain keeps going, it will be for everyone’s benefit
