PG&E’s Almaden eight-story office building in San Jose, California contains a Phone Center and two support areas that operate 24 hours a day, seven days per week. FSI was hired to perform an energy audit then contracted to provide guaranteed energy savings based on the audit.

Prior to retrofit, the building was using 23.4 kWh and 7 therms per square foot per year. The audit identified $143,000/year in energy savings for a cost of $430,000 providing a three-year payback. PG&E received an award from Energy User News for the office facilities category in 2001.
