California Twin Towers
4900 California Ave.
Bakersfield, CA 93309
Arden's California Twin Towers property located at 4900 California Avenue, Bakersfield, California is a 155,189 rentable square foot building that is 82% occupied. As part of the company's ongoing energy efficiency program, California Twin Towers, constructed in 1983, was chosen as a candidate for the installation of a new Energy Management System and a building wide lighting retrofit. 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.
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.
