The biggest single energy use for most people is space heating. For a new build this means working to Passive House standards. These should be mandatory in the building regs but the housebuilding lobby has too much influence for that and they have to be dragged kicking and screaming all the way. Another problem is that for both homes and offices the people who commission the building are not usually those who pay the bills.

Upgrading an older house is more difficult and expensive. After easy wins like loft insulation and draught elimination it's harder. Good quality double glazing isn't cheap. For solid walls, internal insulation loses space while external is very expensive. It's also unfortunate that some previous schemes have been badly thought out. A lot of cavity wall insulation has been badly done and has caused damp. A house with no draughts and minimal air exchange will get horribly damp unless correct ventilation is used. For the average hosueholder this all needs to be as automatic and hassle free as possible.
