EPA Announces Top 10 Cities for Energy Star Buildings
Stumble it!
Many people think of energy-efficient appliances when they hear Energy Star, but they also rate buildings. The EPA today is announcing the top 10 US cities with the most Energy Star-rated commercial buildings.
Why is this important? Well energy use in commercial buildings and plants accounts for nearly half of the total U.S. greenhouse gas emissions and nearly 50 percent of energy consumption nationwide. In 2008 alone, more than 3,300 commercial buildings and manufacturing plants earned the Energy Star rating for excellent energy performance. These energy-efficient buildings saved more than $1.1 billion in energy costs and reduced more than 7 million metric tons of greenhouse gas emissions in 2008, which is a savings equal to the emissions from electricity use of more than 1 million homes for a year.
The Top 10 cities announced today are, not surprisingly, led by two California cities– Los Angeles at number 1 and San Francisco at number 2. Los Angeles weighs in with around 250 Energy Star buildings, and San Francisco has around 200. Quite surprisingly Houston, Texas is number 3, with 150 buildings. (They prove once again, Don’t Mess with Texas.) Also on the list are Chicago, Dallas, Seattle, and Washington DC. You can see the full list of the Top 10 and learn more about their green buildings here.
What makes a building an Energy Star building? To qualify for EPA’s ENERGY STAR, a building or manufacturing plant must score in the top 25 percent using EPA’s National Energy Performance Rating System. Buildings can be rated on an energy performance on a scale of 1-100 relative to similar buildings nationwide using the EPA’s Portfolio Manager tool. Buildings that earn a rating of 75 or greater may qualify for the Energy Star designation. Buildings are rated on such factors size, location, number of occupants, number of PCs, heating and cooling systems, etc. You can learn more about the Energy Star building system here.
