Energy Performance

It is important that we all strive to cut our carbon dioxide emissions but I am taking the recommendations in the Energy Performance Certificate (EPC) that I received when purchasing my house (below) with a pinch of salt. Unfortunately, they are less than helpful and bear out concerns expressed by the SPAB (Society for the Protection of Ancient Buildings) when EPCs were introduced as part of Home Information Packs (HIPs) in 2007.

No previous experience is necessary to train as a domestic energy assessor to produce EPCs and those who qualify frequently display a worrying lack of understanding when dealing with old buildings. This is compounded by the fact that the software used can discriminate against older, more complex properties. Consequently, the recommendations given in EPCs are too often for work that would not only be damaging to historic fabric but result in little, if any, environmental benefit.

Even so, I was aghast at the assessor’s recommendation that the thermal efficiency of one of my two cottages could be improved by applying external wall insulation and the claim that this “might improve the look of the house”. So much for the building’s grade I listing and the national significance of its pargeting! Fortunately, there are many other, more appropriate ways in which I could cut my energy use and I plan to incorporate a range of these into the forthcoming project.

Good advice on reducing energy consumption in old buildings can be found at www.climatechangeandyourhouse.org.uk and www.historic-scotland.gov.uk.
