Artificial intelligence is beginning to monitor building performance in real time. Taken together, these advances are challenging the long-held assumption that better buildings inevitably cost more. “The best square footage is the square footage you didn’t build,” Eighmy says. He also emphasizes the implementation of smart controls that continuously optimize building performance, and AI platforms capable of detecting mechanical failures before occupants notice a problem. “AI is helping us build better energy databases, review drawings for conflicts, and optimize buildings continuously instead of waiting until something breaks,” Barna notes.
