Asia Pacific at Johnson Controls. “In this project, we joined hands with Microsoft to raise the bar on what is possible for energy-efficient buildings, and its faith in Johnson Controls AI-enabled OpenBlue Net Zero Buildings solution has been proven out. The energy and emissions savings on the Beijing Campus project help Microsoft and us to highlight what is now possible sustainability-wise for retrofit buildings programmes in China.” The Microsoft campus also uses Johnson Controls Metasys Building Automation System (BAS), a solution which connects heating, ventilation and air conditioning with lighting, security and fire protection systems on a single platform to provide better data visibility and inform decision-making. In monitoring the campus’s cooling and heating equipment, Metasys directs large amounts of data into OBEM for analysis. During Johnson Controls’ retrofit of the campus, it upgraded Metasys and integrated it with the campus’s legacy BAS. With more sub-systems connected into Metasys, Microsoft was able to reduce field operations risk and improve workplace comfort for employees. The implemented solutions have also increased equipment uptime at the Microsoft Beijing Campus by more than 98 per cent and have improved the level of operational automation. The improvements add to the sustainability work that Johnson Controls has been supporting Microsoft Beijing Campus with since 2010. The earlier collaboration saw the campus reduce its power consumption by more than 30 million kilowatt-hours between 2011 and 2020. This long-term project with Microsoft adds to a growing portfolio of projects that demonstrate the potential of the Johnson Control OpenBlue platform to cost-effectively use advanced technology to reduce emissions. 65
