Arden's property, located at 1370 Valley Vista Drive in the city of Diamond Bar, California is a 84,081 rentable square foot, two story office building that is 92% occupied. 1370 Valley Vista, constructed in 1988, is air conditioned by four Mammoth package units capable of producing 240 tons of refrigeration. A Siemens Energy Management System, installed early this year, controls the operation of the HVAC system. The air distribution system is variable volume with static pressure control via variable frequency drives. Heating is supplied to the perimeter zones only by a gas fired hot water boiler. As part of the company's on-going energy efficiency program, 1370 Valley Vista was chosen to have a lighting retrofit. The retrofit consisted of replacing the standard F-40 lamps with energy efficient T-8 lamps. Furthermore, new occupancy sensors were added to the system. This work was completed in 1999.

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.
