The Most Awarded ENERGY STAR Building in the U.S.

Recently, the U.S. Environmental Protection Agency (EPA) recognized the only building in the United States to achieve a remarkable 15 consecutive ENERGY STAR certification labels: the U.S. Airways/American Airlines headquarters building in Tempe, AZ. Since the ENERGY STAR certification for buildings began in 1999, the building has met strict energy-efficiency standards set forth by the EPA.

This nine-story, 218,000-square-foot office tower was named as the 2000 Building of the Year by the Arizona Chapter of the National Association of Industrial and Office Properties (NAIOP) right after it was built in 1999. Since then, it has benchmarked its energy usage and received an ENERGY STAR rating every year (and its score has increased almost every year). The building also earned LEED-EB Gold certification in 2009, with a recent LEED-EB re-certification in 2014.

The U.S. Airways/American Airlines building’s very first ENERGY STAR rating was 75. Today, the building’s current ENERGY STAR rating is 96. As compared to the average U.S. office building, it is 52% more energy efficient; according to Hines, the building’s property manager, this means that the building saves $1.53 per square footin energy costs. The building also uses 31% less water than comparable U.S. office buildings.

A few of the energy conservation measures being implemented at the U.S. Airways/American Airlines building include:

  • Energy-efficient lighting in the building and parking garage
  • High-efficiency air filtration and air-handling systems
  • Demand limiting program that monitors electricity demand on each floor and resets interior temperatures accordingly

The building also incorporates several water conservation methods, such as:

  • Xeriscape desert landscaping that requires little or no irrigation in order to survive
  • Low-flow aerators at each lavatory
  • Dual-flush valves on all toilets in restrooms

The building also practices high-performance green cleaning and recycles as much paper and waste as possible.

What is your building’s ENERGY STAR rating? How many years have you been benchmarking your facility’s energy use?
