Case Study: Limbach achieves $1,500/month energy savings and extended chiller life with JadeTrack real-time monitoring

Real-time Data Optimizes Building Automation System for Energy Savings

Limbach Engineering Services worked with a school district that owned about 20 buildings and had one persistent poor performer — a 140,000 sq ft school with typical HVAC tied to a building automation system (BAS). Using JadeTrack real-time monitoring, Limbach sought to find the root cause of higher-than-normal energy use when the district couldn’t pinpoint the problem from existing controls and reports.

JadeTrack’s live, whole-building energy data let Limbach identify a chiller short‑cycling caused by faulty BAS logic and implement a corrected control sequence, which immediately smoothed chiller operation, reduced undue wear, and saved about $1,500 per month. JadeTrack data also revealed large air handlers left running; after fixes the building’s ENERGY STAR score rose 19 points and its performance aligned with other district buildings.
