Arden's 625 The City located at 625 The City Drive in the city of Orange, California is a 139,806 rentable square foot, four story office building that is 94% occupied. As part of the company's ongoing energy efficiency program, 625 The City, constructed in 1985, was chosen as a candidate for the installation of a new Energy Management System to control the 90 water source heat pumps that provide the air conditioning at the property. In addition, the system controls the operation of the hot water boiler, circulating pumps, and fluid cooler variable frequency drive. Until the installation of this system, the heat pumps operated via tenant controlled by-pass timer switches. Often, the miss-use of these switches caused the heat pumps to operate well beyond the hours required to provide tenant comfort.

The installation of the Energy Management System allowed the building personnel to set the start/stop schedule to normal business hours of operation. Tenants can get after hours air conditioning via a telephone modem. This installation has significantly reduced electrical consumption at the property.

Arden Realty, Inc., with over 240 buildings in seven markets, is currently the largest commercial office landlord in Southern California, operating over 18 million rentable square feet with an additional 285,000 square feet under development. We have completed 32 HVAC plant retrofits, 47 EMS systems, 20 carbon monoxide sensor projects and 117 individual building lighting retrofits, including occupancy sensor installation. Arden Realty has also completed seven cogeneration plants and one solar photovoltaic array with a total capacity of three megawatts.
