I hate it when I see energy diagrams like this and it reads in the red, so I thought I'd explain How To Read an Energy Efficiency Diagram. The truth is though, most people haven’t a clue what this diagram means. They all assume G is bad, but they don’t actually know why it’s bad. Starting simply, this is an Energy Efficiency Diagram. The higher the ratings on this graph, the lower fuel bills are likely to be. Your homes energy rating is measured in SAP points (it’s all to do with the amount of carbon dioxide your home produces). The more SAP points you have, the better your efficiency. There’s a few appliances that can have dramatic improvements on your SAP score, and they’re easy to come about if you talk to the experts. Condensing boilers boost your SAP points by 47, Cavity Insulation by 13 and Roof Insulation by 10 points. The average energy efficiency rating for homes in Britain is actually ‘D’. And that, my friends, is How To Read an Energy Efficiency Diagram.
