How a Hospital Cut OR Complaints and Energy Waste with Simple Wireless Monitoring

This NexusCon 2025 session features Conor Cleary of Tefiki tackling one of the hardest problems in smart buildings: how to drive real energy and comfort improvements in the 87% of buildings that lack modern controls. Conor walks through a live hospital case study—an aging, 1970s-era facility with 800 beds, overstretched maintenance staff, and zero tolerance for downtime—where traditional BMS upgrades weren’t an option.

Instead of ripping and replacing, the team focused on a small, high-impact area: four AHUs serving eight operating theaters. The result was a simple, low-disruption approach that delivered visibility, stability, and fast ROI without adding complexity.

Inside the recording, you’ll hear why starting small beat trying to “fix everything,” and how wireless sensors and a cloud overlay exposed issues the legacy BMS completely missed. Conor shares what surprised them most—how quickly surgeon complaints dropped once staff had real-time alerts—and what they deliberately didn’t touch (no AHU reprogramming, no controls overhaul).

You’ll also get concrete numbers, including sub-12-month ROI and estimated 10–15% HVAC savings from eliminating 24/7 runtime. If you’re responsible for older hospitals, schools, clinics, or small commercial buildings with limited staff and capital, this session shows exactly how to unlock savings without overengineering the solution.
