'Energy Score' worries for America's houses?

Pilot program will rate real estate based on energy use

When Shaun Donovan first mentioned the idea to me shortly after taking over as Obama’s housing secretary, it sounded completely commonsense and reasonable.

"When you buy a car," he said, leaning across the table for emphasis, "you know very clearly what the energy efficiency of the vehicle is because there’s a number on the window. It says, ‘Here’s the gas mileage.’ But we don’t know that" when we buy a house, even though it’s a much larger expenditure.

Most houses come with no stickers, no ratings and no disclosures about how big a fuel guzzler the property is, and how that might compare with other houses on a rating scale.
