Which Cities Have the Most Efficient Buildings?
The Environmental Protection Agency released a list of the cities with the most Energy Star labeled buildings this week. Have a look:It's an interesting list, but showing the percentage of Energy Star buildings, or the number of Energy Star buildings per capita, would be better as a gauge of a city's overall building efficiency, of course. I quickly compared this list to the list of biggest U.S. cities and calculated that Washington, D.C. has 0.34 Energy Star buildings per 1,000 people. But Lakeland, Florida is the real winner with 1.34 Energy Star buildings per 1,000 people! And, in case you're wondering, the Energy Star label takes into account regional weather data, so California and Florida don't seem to have any unfair advantage.Anyway, we're all winners: The EPA says that the 3,900 buildings that won Energy Star ratings in 2009 cut carbon dioxide emissions by more than 4.7 million metric tons and saved $900 million.
