Arden's 100 Broadway property located at 100 West Broadway, Long Beach, California, is a 193,390 rentable square foot building that is 94% occupied.

As part of the company's ongoing energy efficiency program, 100 Broadway constructed in 1985, was chosen as a candidate for the installation of a new Energy Management System (EMS). A building wide lighting retrofit was also performed. These additions were conceived as part of the overall efficiency enhancement at the property.

The Siemens Energy Management System controls fan coil operation, chiller staging, load shedding, start/stop timing, and condenser water temperature. We control reset on supply air temperature.

A typical Arden lighting retrofit was accomplished by replacing T-12 light tubes with T-8 light tubes and installing electronic ballasts. All 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.

In addition to all the lighting and mechanical upgrades, many no cost / low cost measures were taken that reduced energy consumption. These included:  Demand side management programs including EMS control to monitor the kW peak demand and monthly review of peak demand. Reducing simultaneous heating and cooling to a minimum. This due to the operator spreading the load over time, via optimal start strategy and using the EMS.

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 3.5 years with a marked increase in tenant satisfaction and comfort.  Arden Realty, Inc. with over 240 properties, is currently the largest commercial office landlord in Southern California, operating over 18.5 million rentable square feet. We are currently planning or constructing 20 HVAC plant retrofits, 30 EMS systems, 15 carbon monoxide sensor projects, and 100 whole building lighting retrofits, including occupancy sensor installation.
