The Environmental Protection Agency is calling it the "Battle of the Buildings". The teams will be working to see who can improve energy efficiency and reduce energy use the most. EPA Deputy Administrator Bob Perciasepe says this is not being done for fun. Buildings use a lot of energy.
"Energy use in commercial buildings account for about 20% of the total U.S. greenhouse gas emissions and energy use, at a cost of more than 100-billion dollars a year."
He says achieving Energy Star status isn't just for bragging rights, it's good on several levels.
"Retail stores, office buildings, and schools that have earned the Energy Star use 35 percent less energy, emit 35 percent less greenhouse gasses, and are protecting the health of our families and the environment."
Two of the Houston buildings taking part are Lakewood Church and Wells Fargo Plaza.
Competitors will measure and track their building's monthly energy consumption using an EPA Energy Star online energy tracking tool. A group of finalists will be selected in July with the winner announced in November.
