  1. During my presentation at the conference I highlighted that maintenance is also an energy efficiency measure. I pointed out that the new British Standard BS7913: Guide to the Conservation of Historic Buildings, also makes this point. It states that walls could be some 30% less energy
    efficient if damp and this all point towards keeping buildings in good repair to save energy. I highlighted that research by the Society for the Protection of Ancient Buildings and by Cadw (Welsh Government) had also highlighted this factor. Unfortunately this isn’t considered in any current official form of energy assessment. The key message is to think about proper maintenance before any ‘measures’!
