$this->bbcode_second_pass_quote('emersonbiggins', 'T')here is a system in place to demonstrate how 'green' a building is, which (of course) includes per capita energy usage.
It is known as LEED (Leadership in Energy and Environmental Design), which covers most construction types nowadays. It is an initiative of the U.S. Green Building Council and is highly respected in both green and architectural circles.
Buildings are rated ("silver", "gold", etc.) according to a punchlist of design items integrated within the design of that building.

That's a start, but something quantitative like MPG for cars would make it easier to compare two buildings. Something like the EnergyGuide for appliances (which estimates annual energy usage in kWh and shows a range scale indicating where the appliance fits). An EnergyGuide for a building could take into account the energy costs of the appliances within it, which are the direct energy consumers (a/c, water heater, range, fridge, washer, dryer, etc). Unfurnished homes could use the average energy value of the appliance needed to fit their given size (or (L + H) / 2 method).
Seems like that would produce more meaningful numbers than just a rating. Of course there is the problem of taking the buildings intrinsic energy saving qualities (insulation, windows, size, etc) into account which this scheme doesn't address...
