DescriptionThis report summarizes the results of a field trip by Aamer Athar, Dr. Mingsheng Liu of the Energy Systems Laboratory and Mr. Yorg Mager of the University of Florida for identification of O&M opportunities at the Neil Kirkman Buildings. Several O&M opportunities were investigated and savings were estimated. By locking in the fan operation with the chiller all the AHUs could be turned off during the unoccupied hours. The potential annual savings are $33,000 (only includes fan power savings). It does not include chiller and pump electricity savings. Chillers could be operated in an optimized mode where they could be also shut off during the unoccupied hours. Correcting the current air flow, based on the current load conditions, would remove most of the foot heaters. The potential savings are approximately $8,000/yr. Resetting the cold deck temperature based on outside air temperature and by keeping the chiller on during occupied hours would also save energy and cost.
