Field evaluation of performance of HVAC optimization system in commercial buildings

Energy savings analysis was conducted based on pre/post submetered energy use. Across the cohort of evaluation sites, HVAC savings following the implementation of the optimization system were mixed, ranging from 0-9%. Analysis of site operational data showed that occupant comfort was neither positively nor negatively impacted. Key technology adoption considerations and recommendations are summarized in the paper. The technology performs best when HVAC systems are in good working condition, and can be exercised to achieve the full range of its optimized setpoints-however it may not provide extensive additional savings over cases where best practice sequences of operation and reset strategies are already comprehensively implemented.
