University Hospital is a 1,400,000 square-foot healthcare facility in Augusta, Georgia. It has undergone a number of expansions, most recently a heart center currently being commissioned. Due to a need to reduce operating costs, the Hospital engaged American Energy Assets to reduce the Hospital’s energy consumption.
The Hospital’s cooling system is served by two interconnected chiller plants, a waterside economizer heat exchanger, and a new additional chiller being brought on-line with the Heart Center expansion. A major factor in overall efficiency is the proper staging of the various chilled water systems. The hospital also has a number of very old air handlers, along with some brand new equipment.
AEA implemented its On-Track Program on January 1, 2009 to diagnose and correct inefficiencies within the facility. During initial energy assessments, AEA identified the following opportunities for improvement:
Based on engineering surveys and in-depth analysis of data gathered from the Building Automation System, AEA and University Hospital have made the following modifications through the first year of the program:
Through the first 13 months of the program, AEA and University Hospital have generated almost $430,000 in energy cost savings, without any major capital expenditures. On top of this, their energy usage index has decreased from 240 to 210 kBTU/SF. The buildings Energy Star profile also improved from a baseline rating
