Orientation is captured here too but that's not to say its going to capture actual energy performance. Two identical houses could have a different number of people living in them who use the house differently (e.g. WFH/not). But it wasn't supposed to. And it shouldn't have all policies based on it

It's a big plus that orientation is considered. I 'experted' in this stuff in the UK many years ago, now I'm (retired) in Italy and I sort of despair about the rather (IMO) 'accountancy' approach to energy efficiency. But it's what the mortgage offerers want to see.
