Arden's World Savings Center located at 11601 Wilshire Boulevard, Los Angeles, California is a 469,155 rentable square foot building that is 95% occupied. As part of the company's ongoing energy efficiency program, World Savings Center, constructed in 1983, was chosen as a candidate for the installation of a new Energy Management System (EMS). Other upgrades include a building wide lighting retrofit, carbon monoxide monitoring system and the installation of Variable Frequency Drives (VFD) on various pumps and fans. A typical Arden lighting retrofit was accomplished by replacing T-12 light tubes with T-8 light tubes and installing electronic ballasts. Also installed were occupancy sensors throughout the building to reduce unoccupied lighting energy. The Siemens DDC Energy Management System controls all heat pumps, lighting, cooling towers, load shedding, start/stop timing, and condenser water temperature control. The carbon monoxide monitoring system provides 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.
