Arden's Havengate property located at 10350 Commerce Center Drive in the city of Rancho Cucamonga, California is a 80,557 rentable square foot, three story office building that is 84% occupied. This building was constructed in 1985. Havengate has been equipped with an Alerton Energy Management System to control the building's HVAC system. Air conditioning is provided by twelve Carrier Heating/Cooling package units with a total capacity of 180 tons. Each unit has an outside air economizer. The building has a Carrier VVT air distribution system that is electonically controlled. The operation of the Carrier package units is controlled by the Alerton Energy Management System. The system controls start/stop, compressor loading, temperature control, outside air economizer and static pressure. It also controls the reset program for the heating system.

As part of the Arden's on-going energy efficiency program, Havengate was chosen to have a lighting retrofit. The retrofit consisted of modifying the existing three tube fixtures by adding reflectors, reducing the number of lamps from three to two, and replacing the standard F-40 lamps with energy efficient T-8 lamps. Furthermore, new occupancy sensors were added to the system.

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.
