WASHINGTON - Today, the U.S. Environmental Protection Agency (EPA) released its seventh-annual list of the top 25 U.S. metropolitan areas with the most Energy Star certified buildings in 2014. This year, Los Angeles ranks second, San Diego ranks 17th and Riverside ranks 14th. EPA's Energy Star Top Cities list shows how cities across America, with help from Energy Star, are embracing energy efficiency as an effective way to save money and reduce greenhouse gas emissions that fuel climate change.

"Cities across Southern California have saved more than $196 million and reduced carbon dioxide emissions by 400,215 tons because of energy efficient buildings and upgrades," said Jared Blumenfeld, Regional Administrator for the EPA's Pacific Southwest office. "Nationwide, these efforts are essential to reduce greenhouse gas emissions and the negative effects of climate change."

More than 25,000 buildings across America have earned EPA's Energy Star certification since 1999. The buildings have saved nearly $3.4 billion on utility bills and prevented greenhouse gas emissions equal to the emissions from the annual electricity use of nearly 2.4 million homes. Los Angeles has reduced carbon emissions by 321,139 metric tons while San Diego and Riverside have reduced 48, 255 and 30,821, respectively.

Energy use in commercial buildings accounts for 17 percent of U.S. greenhouse gas emissions at a cost of more than $100 billion per year. Energy Star upgrades have saved Los Angeles over $155 million, San Diego over $22 million and Riverside over $19 million. Energy Star certified buildings are verified to perform better than 75 percent of similar buildings nationwide, and they use an average of 35 percent less energy and are responsible for 35 percent fewer emissions than typical buildings. Many common building types can earn the Energy Star, including office buildings, K-12 schools, hotels, and retail stores.

The program starts with tools to help building owners or managers understand how their buildings are currently performing and what to aim for in terms of improvements. A typical upgrade includes the following: tuning up the building systems; reducing lighting loads; reducing supplemental loads (e.g., equipment, wasteful behaviors, leaky windows, poor insulation, etc.); improving air distribution systems; and making upgrades to heating and cooling equipment. The stages, when followed in order, account for the interactions between different building systems. For example, replacing heat-producing incandescent bulbs with cool CFLs or LEDs will mean that a building's air conditioner won't have to work as hard in the summer months, so a building may be able to downsize its cooling system based on the new lighting's heat output. Another benefit of the five-stage approach is that it ensures the lowest-cost measures are tackled first. As organizations progress through the five stages, they can roll their cost savings into larger and larger investments, culminating in the last, most expensive stage. By the time organizations start making upgrades to heating and cooling equipment, they typically have already amassed substantial cost savings from previous lower-cost improvements.

To create the annual top cities list, EPA tallies the number of Energy Star certified buildings for that particular year within each metropolitan area, as defined by the U.S. Census. These areas include the city itself as well as surrounding towns and suburbs.

The top 25 cities are:

Rank Metro Area 2014 Building Count
1 Washington, DC 480
2 Los Angeles 475
3 Atlanta 328
4 New York 299
5 San Francisco 292
6 Chicago 251
7 Dallas-Fort Worth 248
8 Houston 235
9 Denver 195
10 Boston 176
11 Phoenix 165
12 Philadelphia 158
13 Seattle 149
14 Riverside, Calif. 127
15 Minneapolis-St. Paul 122
16 Charlotte 95
17 San Diego 92
18 Miami 90
19 Sacramento 89
20 Virginia Beach 81
21 Detroit 80
22 San Jose 70
23 Austin 65
23 Portland, Ore. 65
24 Louisville 59
24 Tampa 59
25 Salt Lake City 55

Energy Star is the simple choice for energy efficiency. For more than 20 years, people across America have looked to EPA's Energy Star program for guidance on how to save energy, save money, and protect the environment. Behind each blue label is a product, building, or home that is independently certified to use less energy and cause fewer of the emissions that contribute to climate change. Today, Energy Star is the most widely recognized symbol for energy efficiency in the world, helping families and businesses save $300 billion on utility bills, while reducing greenhouse gas emissions by two billion metric tons since 1992.
