Arden's 70 South Lake property located at 70 S. Lake, Pasadena, California is a 100,133 rentable square foot building that is 97% occupied. As part of the company's ongoing energy  efficiency program, 70 South Lake, constructed in 1982, was chosen as a candidate for a lighting retrofit. This addition was conceived as part of the overall efficiency enhancement at the property. In addition to the lighting retrofit the building also received a seimens energy Management system. These upgrades were 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 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:


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.

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.
