dc.descriptionThe suggested O&Ms include optimizing the HVAC operation schedule, calibrating and relocating of some of the cold deck temperature sensors. The optimized schedule was determined using an analysis involving a simplified HVAC model, which was calibrated against daily data measured by the LoanSTAR program. It is estimated that annual savings of $174,000 can be realized by changing the EMCS control program and calibrating the temperature sensors of the cold deck. The majority of energy savings occur because the optimized operation schedule reduces reheat substantially. Our analysis indicates that the indoor comfort level will not be degraded by this measure. The lighting levels in the corridor and nurses station areas are currently substantially higher than Illuminating Engineering Society (IES) suggested values. The suggested delamping can reduce annual electricity energy costs by $46,000. These two measures can reduce the building's annual energy costs by $220,000, or 22% of the annual building energy cost.en
dc.description.abstractThe LoanSTAR Monitoring and Analysis Group was requested by UTMB to investigate O&M measures in their five LoanSTAR program buildings. This report describes the suggested O&M measures in John Sealy South Building, an out-patient building of 373,000 ft2, currently costs $990,000 per year on electricity, steam and chilled water.en
