The idea of a national building code is gaining momentum, having been included in a climate-change bill that was passed in the U.S. House of Representatives in June and forming part of a climate proposal currently being worked out by Sen. Richard Lugar (R., Ind.).
Having a one-size-fits-all minimum standard of how efficiently buildings should use energy, among other things, would force the hand of builders, who currently operate under a patchwork of state and local rules and voluntary standards. But the idea of forcing that change is controversial.
