The steam investigation.

A Fifth Avenue boutique hotel saw steam up 80% and electricity up 66% year over year. We traced it to a simultaneous heating-and-cooling fault, a steam-to-hot-water heat exchanger running through summer while chillers fought it, confirmed with segregated steam meters, IR readings, and four years of verified data. Full remediation modeled at $3M+ in cumulative savings and avoided penalties through 2034.
