Potential Operation and Maintenance (O&M) Savings in the Clinical Science Building at UTMB
MetadataShow full item record
This report presents the results of a study of the potential energy savings due to optimizing the Heating, Ventilation and Air Conditioning (HVAC) operation schedule in the Clinical Science Building at University of Texas Medical Brach (UTMB) Galveston, Texas.
DescriptionAn optimized HVAC operation schedule has been developed using the simplified model analysis with the LoanSTAR measured hourly data and the EMCS measured operation parameters at UTMB. An annual savings of $73,700 can be realized by implementing this optimized schedule by changing the EMCS control program. The majority of the energy savings are due to the reduction in chilled water consumption and the substantial reduction of reheat. Our analysis indicates that the indoor comfort level will not be degraded by this measure. It can reduce the building's current annual energy costs by $73,700 or 21%. This report discusses a simplified model analysis and the methodology of identifying one type of O&M improvement and summarizes the potential savings from this measure.
