Arden Realty Alliance with Siemens Saves $650,000 a Year in Energy
To date, Arden, Southern California's largest commercial office landlord with over 20 million square feet in 253 buildings, is saving $3,500,000 annually in energy costs across its portfolio. The savings derive from a combination of energy saving initiatives and operating efficiencies designed to reduce energy consumption. The energy program was designed and directed by Arden's own staff, including Robert C. Accomando PE, first vice president, asset management, Greg Husebye, vice president of engineering, Duane Lappinga, senior project manager and James Bryan, regional engineer. Implementation was made possible by the contributions of 124 regional, chief, and building engineers.
A strategic alliance with Siemens Building Technologies, which included the installation of energy management systems in many of Arden Realty's buildings, played an important part in the savings achieved. The combined initiatives, says Accomando, have provided the firm with a sizable return on its investment. "The measures we have implemented," he says, "have reduced our net operating expenses significantly, while arming us with powerful information about the way we operate our facilities. The lighting control measures alone, Accomando says, "are showing a drop in lighting costs of 65% when and where they are applied. As a result, we've strengthened our competitive edge and widened the distance from our competitors."
