Howard Hughes Tower
6701 Center Drive West
Los Angeles, CA 90045
Arden's Howard Hughes Tower property located at 6701 Center Drive West, Los Angeles, California is a 329,228 rentable square foot building that is 97% occupied. As part of the company's ongoing energy efficiency program, Howard Hughes Center, constructed in 1986, was chosen as a candidate for the installation of a building wide retrofit. This addition was 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. Electronic ballasts were also installed. The incandescent and fluorescent exit signs were replaced with LED exit signs using only 2 watts per fixture. Also installed were occupancy sensors throughout the building to reduce unoccupied lighting energy. The Siemens Management System installed variable speed drives on all fans, load shedding, start/stop timing, and condenser water temperature. We control and reset the supply air temperature as well as the static pressure. 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 operations towards peak demands 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 occupancy comfort.
The payback for these initiatives is approximately three and a half years with a marked increase in tenant satisfaction and comfort.
