About This Item
Full Description
Points out that in most chiller and boiler central plants the energy management and control systems (EMCS) continuously monitor and record key operation parameters and energy production. Describes a method developed to identify potential operations and maintenance (O&M) savings by using the EMCS-recorded data. Reports the method was applied to a central plant that supplied heating and cooling to a university campus with a total building floor area of 3.5 million ft2 (325,000 m2). Finds the potential savings from improved O&M were $2,651,000 per year. Improved air handling units operation was fully or partially implemented in a number of buildings. The measured O&M savings of $610,000 per year or 22.5% were consistent with predicted savings.
