Stars of Energy Efficiency

Energy audit, summer conservation mode earn EFH, TXU Energy and Luminant office buildings Energy Star recognition


Four company office buildings, including TXU Energy's headquarters in Irving, have received Energy Star recognition.

Four company office buildings, including TXU Energy’s headquarters in Irving, have received Energy Star recognition.

Though Energy Plaza, the downtown Dallas headquarters of EFH and Luminant, is consistently recognized for energy efficiency, we’re always looking to ensure energy-efficient practices are incorporated into all of the company’s building management programs.

Thanks to an energy audit, summer energy conservation mode and other measures conducted by our facilities team, Energy Plaza, two of TXU Energy’s buildings in Irving and our Mesquite Data Center have received the U.S. Environmental Protection Agency’s prestigious Energy Star recognition for 2014.

This is the seventh consecutive Energy Star for Energy Plaza – which was also just named the first Certified Sustainable Property in the U.S. – and the sixth consecutive award for TXU Energy’s headquarters. Both TXU Energy’s Customer Operations Facility and EFH’s Mesquite Data Center have been recognized four times.

The Energy Star designation is a national symbol for superior energy efficiency and environmental protection. Commercial buildings that earn the Energy Star use an average of 35 percent less energy than typical buildings and also release 35 percent less carbon dioxide into the atmosphere.

During the sweltering Texas summers, we’re reducing our electrical load by:

  • Turning off lobby lighting and all unnecessary lighting throughout our buildings
  • Raising the temperature inside buildings to 75 degrees
  • Adjusting building management systems to delay the startup of mechanical/HVAC equipment throughout the buildings where applicable
  • Lowering all shades to reduce evening heat load

At Energy Plaza and TXU Energy’s headquarters in Irving, lobby and atrium lighting are turned off each day at noon, while emergency lighting remains on, and the sky bridge and foyer temperature are increased to 78 degrees.

At the Mesquite Data Center, occupancy sensors have been added throughout the building and economizers have been installed on the rooftop units, which lower the building’s carbon footprint.

On a monthly basis, the facilities team tracks and records electricity usage at all buildings through its portfolio management tool.

“We’re committed to ensuring that our facilities exemplify environmental stewardship,” says Bob Keith, EFH senior director of facility and real estate services. “We strive for continuous improvement in our reliability and energy management and sustainability practices.”
