What would the "insulation rating" cover? E.g. the R-value of the stuff inside walls, which wouldn't cover windows or gaps or lots of other things, or do they somehow measure the R-value of the house as a whole?
Every house and rental I've encountered so far has given me the monthly heating/cooling cost up-front, which has so far been fairly accurate, assuming you hold at an area-normal temperature indoors. And they've all been able to tell me the R-value of the insulation in the walls and roof or attic. If ever it's more than like $100 for a single-family home, you pretty much know the insulation is bad or terrible.

- Groxx 6y agoAh. So basically a multi-tier building code that builders/etc certify during their work? Makes sense - I'm not sure if there's an equivalent in USA or not. There are certainly minimums in most/all? places, but I have no idea how much consistency there is. The bigger problem is probably that there are a bunch of old, cheap buildings in places that experienced major housing booms during lax requirements, and those still exist :|
- londons_explore 6y agoIn England at least, energy performance certificates are widely faked. Anything the inspector can't verify they are allowed to estimate. So you get things like "I'm afraid the curtains are closed now, so we can't see the windows, but I estimate they're double glazed".
