Demonstration of Advanced Building Operation Management Using AI Constellation® Validates Effectiveness in Event Planning and Signage Optimization

NTT Urban Solutions, Inc., NTT docomo Solutions, Inc., and NTT docomo Business, Inc. (formerly NTT Communications Corporation) announced a joint demonstration utilizing "AI Constellation®," a large-scale AI collaboration technology. The project aimed to enhance and streamline building operation management by having multiple specialized AIs, fed with district data, interact and collaborate to generate optimal solutions from diverse perspectives. The demonstration focused on two tasks: 1) developing event proposals and 2) optimizing content display on digital signage. The results confirmed a reduction in planning time and improved quality from multiple viewpoints for event planning, and a positive effect on behavioral changes after viewing the optimized signage content. This release outlines the demonstration's background, an overview of AI Constellation®, and the detailed results. For event planning, using the system led to a roughly 50% reduction in work hours, equivalent to saving about 30 person-days annually. For signage optimization, there was a 4% increase in average views per person and a 6% increase in movement from the signage floor to the tenant floor, with this rate jumping by over 30% during the pre-lunch hours. Moving forward, the companies will consider practical implementation, expand AI's role in building management to create replicable operational models, and explore broader applications in smart city projects, including the NTT Hibiya Tower scheduled for completion in 2031.
