Delta/JLL decided to cut out reactive “go in the room and check X” rounds—data layer deployment enabled consistent alarms and checks across concourses and building systems
Delta Air Lines and JLL made a deliberate call at LaGuardia Terminal C: stop relying on engineers to walk rooms multiple times a day just to confirm conditions were still acceptable—and replace those rounds with standardized, proactive alerting. At the core was a data layer built on ICONICS, which the team treated as an operational “information broker” rather than another dashboard.
For temperature monitoring, engineers had been doing frequent manual checks. “We were just being very reactive in nature,” said Kate Stelzel, Technology Operations Manager at JLL. The team configured two alarms—75°F and 85°F—so that missing the first alert wouldn’t become a missed incident.
They didn’t implement this directly in the BMS, even though it was technically possible. Different concourses were governed by different contracts, which meant different BMS implementations and alarm behaviors. “We would have had two different workflows, and it was just going to confuse the team,” Stelzel said.
The data layer became the standard interface that made one process possible across fragmented systems.
A similar pattern showed up in fuel monitoring. Previously, the HSE team walked the airport twice a week, checking fuel tanks and ordering deliveries when levels crossed a threshold. “It worked,” Stelzel said, “but it was reactive and labor-heavy.”
Because ICONICS interfaced directly with the fuel system vendor, the team pulled raw tank-height data that wasn’t exposed through the BMS and created a custom “percent full” alarm at 65%. That replaced rounds with virtual tracking, freeing up labor and reducing the risk of running low on fuel.
The takeaway wasn’t about a “single pane of glass.” It was about using a data layer to enforce one operating process—even when ownership and systems were fragmented.

This is a great piece!
I agree.
