Los Angeles: Number one for Energy Star buildings

For the fourth year in a row, Los Angeles has been ranked the number one city with the most Energy Star certified buildings in the US. According to the list of 25 cities, Los Angeles boasts 659 certified buildings, putting it well ahead of Washington DC with 404 and Atlanta with 359. New York is placed sixth despite having added 50 certified buildings to its total in 2011. California has six cities on the 2011 list— more than any other state.

Launched in 1992 by the Environmental Protection Agency (EPA), Energy Star is a voluntary labeling program designed to identify and promote energy-efficient products. Energy Star for Buildings was introduced in 1999, and there are now almost 16,500 Energy Star certified buildings across the country.

Energy use in commercial buildings accounts for nearly 20% of US greenhouse gas emissions at a cost of more than $100 billion per year. Commercial buildings that earn EPA’s Energy Star must perform in the top 25% of similar buildings nationwide and must be independently verified by a licensed professional engineer or a registered architect. Energy Star certified buildings use an average of 35% less energy.
