In partnership with an energy performance contractor, Bergmann completed a comprehensive retro-commissioning study at four sites operated by Genesee County in New York. Field work consisted of physical evaluation of each component, as well as functional testing performed in the field and on the building management system simultaneously.
A deficiency list was developed based on the thorough analysis of the buildings and equipment. Deficiencies included failed reheat valves, lock-out of economizer cooling and modulating outside air dampers that would not respond to direct adjustments made in the control system. A total projected savings of $31,769 could be achieved with the implementation of the necessary improvement measures identified in the survey.
