Cammeby’s International achieves 15.8% reduction in HVAC energy use and costs

Situated in New York City’s bustling financial district, Cammeby’s International 32-storey office property showcases how an older building can adapt to modern challenges. Faced with rising energy costs and regulations, the real estate investment company’s team sought an innovative solution to comply with regulations, optimize energy, and target savings — particularly in its chilled water loop. Cammeby’s International identified BrainBox AI’s AI HVAC Optimization offering as the ideal solution. Process BrainBox AI worked closely with the building’s controls contractor and internal team to program customized graphics for the existing Building Management System (BMS). This allowed the facility team to use their existing tool set and systems to observe the AI in use throughout their building. BrainBox AI HVAC Optimization solution was deployed through our edge device, communicating through BACnet IP. The roll-out was executed floor by floor, in close cooperation with the building’s Chief Engineer, ensuring that tenants remained comfortable and disruption-free throughout. This collaborative effort was key to the customer’s positive experience and the project’s long-term success. Computer rooms at the building require condenser water at all times. BrainBox AI used the design criteria in the centrifugal pump schedule to develop a system curve and determined the minimum flow rate. This data was used as another input for our AI to consider, continuously optimizing valve positions while satisfying the required thermal demand of the server zones. esults Over an 11-month period in 2023, Cammeby’s International realized substantial electricity, emissions, and cost savings. Our AI HVAC Optimization solution drove a 15.8% reduction in HVAC-related electricity consumption, saving $42,951, and mitigating 37.14 tCO2eq. These remarkable results were achieved seamlessly, with the facility engineers noting no disruptions to daily operations — another key objective of the project.
