Wilshire Brentwood Plaza
12400 Wilshire Boulevard
Los Angeles, CA 90025
Wilshire Brentwood Plaza consists of a 15-story high-rise, class "A" building with retail and restaurant space on the first floor and six levels of subterranean parking. The project consists of approximately 236,000 rentable square-feet with a maintained occupancy rate well over 90%.
Constructed in 1985 the project was a good candidate for mechanical and lighting retrofit, as well as no-cost/ low-cost operational strategies to enhance the energy efficiency of the building.
An upgrade of the Metasys System was the first logical step into a long-term solution to merge today's technology with the present mechanical system for this building. The process continued with the installation of 15 variable frequency drives (VFDs) on the air handlers, and the installation of Metasys controls to link the VFDs with the associated mechanical equipment. An after hours control system was installed which allowed occupants to activate after-hours lighting and HVAC in specific areas of demand via telephone. Fine-tuning of the control strategies then allowed for optimum system performance without compromising tenant comfort. The mechanical retrofit realized a simple payback of less than 18 months.
In 2001, a building wide lighting retrofit was completed which consisted of the replacement of T-12 lamps and magnetic ballasts with T-8 lamps and electronic ballasts in all office areas, common areas and parking garage. Incandescent exit signs were replaced with LED exit signs, and occupancy sensors were installed throughout to reduce unoccupied lighting energy. Incandescent lighting in selected areas was also replaced with compact fluorescent lamps. The lighting retrofit realized a simple payback of less than 11 months, with the Los Angeles DWP incentive program.
With the recent energy crisis, we seized the opportunity to involve the tenants in our continuing effort to conserve energy. An energy conservation forum was held to encourage tenants to participate in and implement simple energy conservation measures in their own premises. The implementation of a well-planned cleaning schedule by the janitorial company (Team Cleaning Program) also allowed utilities in an area to be turned off earlier without compromising work productivity and quality.
Since completed, these energy saving measures have resulted in over a 22% annual kWh reduction.
