Earning the ENERGY STAR Label for High Performance Buildings

Buildings earn the ENERGY STAR by achieving a score of 75 or higher on EPA's energy performance rating system and meeting relevant requirements for indoor air quality.


More than 6,200 top performing buildings earned the ENERGY STAR rating through 2008 for being energy all-stars. Total labeled floor space topped over 1 billion square feet for the first time, an increase of more than 55% over 2007.

Industrial Sector:  45 plants have also qualified for the ENERGY STAR since that recognition became available in 2006. They include

• 15 auto assembly plants,
• 19 cement plants,
• 3 wet corn milling plants, and
• 8 oil refineries.

According to Energy Star calculations, the 2008 achievements in Energy Star labeled buildings and plants reflected an overall annual utility savings of more than $1.7 billion and prevented greenhouse gas emissions equivalent to those of more than 2 million cars a year.
