UCLA has been conserving resources through energy efficiency for decades, including replacing over 600,000 light bulbs on campus with more energy efficient bulbs. Since the Climate Action Plan was launched in 2008, UCLA has invested $20 million in energy efficiency, with an overall project payback of 3.8 years, meaning the investment was returned in cost savings in 3.8 years. This includes around $3 million dollars of rebates from our utility, LADWP, and also includes any interest on the debt that funded the projects. These projects included lighting retrofits, heating and air conditioning retrofits, occupancy sensors and more.
This has resulted in a decrease in energy use per square foot, even as we have added over a million square feet of high intensity lab, medical and residential space. Progress is shown on the graph below. 2012 was higher in large part because of an unusually hot summer and increased cooling demand that resulted.
UCLA Energy Use versus Gross Square Footage 2008-2012
Currently UCLA is doing ASHRAE level II audits on 7-10 buildings per year to identify new energy conservation measures. In 2012 the following buildings were audited:
- Perloff Hall
- Kaufman Hall
- Haines Hall
- Bunche Hall
- Engineering IV
- Dodd Hall
- Powell Library
- Rolfe Hall
From these audits, we identified around $3.6 million dollars of projects and have funded close to three million dollars. On completion, these projects will save an estimated $890,000 every year and reduce UCLA’s greenhouse gas emissions footprint by 3,400 tons. The final three buildings, Dodd, Powell and Royce are awaiting funding. The projects identified in the first seven buildings include additional occupancy sensors and lighting retrofits, advanced lighting sensors and drives, as well as conservation measures such as delamping and occupant scheduling. The remaining projects will be completed by the end of 2013, and the next round of audits will begin.
