NYC buildings now have an "efficiency" rating they're required to post on the front of their building. Doesn't give you a $, but maybe a gist of what your energy bill might be like.

In Germany (and I believe the entire EU?) we now have a "building energy passport" that summarizes information like this, broken down into simple numbers and rating scales. It has to be provided when selling or renting a place, and definitely influences behavior.

In theory, perhaps.

But how many people truly have the capability to choose where to live? Most are happy enough to find somewhere they could afford, let alone afford near enough to where they work, and they can't just go find new work to find better (more efficient, in this case) living conditions so easily.

Given the other answers I got shows that this is something that is done and people have found solutions too.

Many people look at multiple places when they are looking for a place to live.

Its unrealistic to think that for most people there is only a single possible place they can live.

So as soon as you have two places you are considering, having information about what future cost will be, will make you help prioritize one over the other.
