  1. I've had my as designed SAP report done and I'm wondering whether it's worth querying the figures or whether it doesn't matter in the slightest. The house isn't designed to PHPP but is an energy efficient build with passive slab; it has lots of glazing. The as designed score is coming in at 84. From what I can see, the chap doesn't understand that I have a pcm thermal store; in fact, he has assumed no thermal store whatsoever as I told him that I wouldn't have a hot water cylinder and sent him info on the sunamp instead. From looking at the figures, it assumes that all heating is electric (correct) and when not powered by PV, will be at a standard electricity day time tariff. The figures also appear to include a whole host of thermal bridges, including sills, lintels and the intermediate floor. Am I making a fuss about nothing?
