Arden's 150 E. Colorado property, located at 150 E. Colorado St., Pasadena, California is a 61,168 rentable square foot building that is 90% occupied. As part of the company's ongoing energy efficiency program, 150 E. Colorado, constructed in 1979, was chosen as a candidate for a lighting retrofit. This addition was conceived as part of the overall efficiency enhancement at the property. The upgrade was specified to reduce wasted energy and reduce operating cost. A typical Arden lighting retrofit was accomplished by replacing approximately 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 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.

In a continuing effort to reduce operating costs, optimum start and stop times have resulted in a further reduction of energy.

Arden Realty, Inc., with over 240 buildings in seven markets, is currently the largest commercial office landlord in Southern California, operating over 18 million rentable square feet with an additional 285,000 square feet under development. We have completed 32 HVAC plant retrofits, 47 EMS systems, 20 carbon monoxide sensor projects and 117 individual building lighting retrofits, including occupancy sensor installation. Arden Realty has also completed seven cogeneration plants and one solar photovoltaic array with a total capacity of three megawatts.
