Barton Healthcare conducted an ASHRAE Level II Energy Audit of the entire hospital, benchmarking performance using the Energy Star database. The audit identified several areas of concern relating to air handler operation –economizer mode control, simultaneous heating and cooling and damper positioning. Retrocommissioning was indicated. The subsequent retrocommissioning study identified the cause of the simultaneous heating and cooling and proposed revisions to economizer sequences. Once completed, the revisions are anticipated to save over $50,000 per year in energy costs while improving occupant comfort.
