Arden's 120 Spalding property, located at 120 Spalding Drive, Beverly Hills, California is a 60,656 rentable square foot building that is 98% occupied. As part of the company's ongoing energy efficiency program, 120 Spalding, constructed in 1984, was chosen as a candidate for the installation of a new Energy Management System. Other upgrades include a building-wide lighting retrofit, Carbon Monoxide monitoring System and the installation of Variable Frequency Drives on various pumps and fans. These additions were conceived as part of the overall efficiency enhancement at the property. A typical Arden lighting retrofit was accomplished by replacing T-12 light tubes with T-8 light tubes and installing electronic ballasts. The incandescent and fluorescent exit signs were replaced with LED exit signs using only two watts per fixture. Also installed were occupancy sensors throughout the building to reduce unoccupied lighting energy.

The Siemens DDC Energy Management System controls refrigeration compressors, all fans, cooling tower, boiler, load shedding, start/stop timing,  supply and condenser water temperature control. The carbon monoxide monitoring systems provide the fan systems with better control allowing them to provide better ventilation in the parking garage while reducing excess energy consumption.

In addition to all the lighting and mechanical upgrades, many no cost / low cost measures were taken that reduced energy consumption. These included:

Arden's engineering department recognizes the financial impact of electrical demand charges and, as such, targets their operation towards peak demand reduction. By monitoring electrical demand levels and establishing a peak target, the energy management systems are programmed to selectively reset equipment to keep the demand within defined limits while never compromising occupant comfort.  

The payback for these initiatives is approximately three and a half years with a marked increase in tenant satisfaction and comfort.

In a continuing effort to reduce operating costs, optimum start and stop times have resulted in a further reduction of energy.

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.
