A mixed-use NYC high-rise was built in 2000 with advanced technology. An energy audit revealed that the BMS had unsupported controllers, an inadequate graphics card, sensors out of calibration and settings errors. Benchmarking confirmed that O&M was inadequate and equipment was not operating as designed. Additionally, staff were not adequately trained in the use of the equipment or the BMS. As a result, the building's energy performance was worse than that of many 100-year-old steam-heated buildings. This presentation will cover the lessons learned from this case study. Moving forward, what options are the most cost-effective way to achieve the intended performance of this building?
