Centerpointe La Palma is a mixed-use office complex comprising three multi-tenant office buildings constructed between 1986 and 1990, with a parking lot exceeding 250,000 SF located next to the buildings.
All of the property’s energy consuming systems were inventoried and evaluated for proper operation. The data collected during the on-site visit included equipment nameplate information, building occupancy schedules, equipment-operating times, and utility bills. Partner Energy used the information obtained during the on-site visit to develop a comprehensive computer model of the facility’s energy use. Based on the model of present energy usage, we developed a list of potential Energy Efficiency Measures (EEMs). Each EEM was evaluated and prioritized based on estimated energy operating cost savings, estimated installation cost, projected Simple Payback Period, and anticipated incentive or rebate amount.
The recommended EEMs included upgrades and retrofits to lighting and HVAC systems such as adding and/or replacing motion detectors, lamps and ballasts, garage lighting and installing high-efficiency air conditioning units, chillers and cooling fans in place of older systems. These recommendations, if implemented, were estimated to save 1,294,034 KWh and $190,702 per year, and provide a simple payback period of 6.55 years.
