Have you checked your
system’s health lately?
Even a district energy system needs a checkup now and then. Take, for instance, these
organizations that called in WM Group Engineers to bring their systems back up to par.
Louisville Medical Center Chilled Water Operating Data
2009: 71.92 million ton-hrs
Production (million ton-hours)
89/90: 21.57 million ton-hrs
Reduced chilled water unit cost by 60%, while tripling total campus production.
Pennsylvania State Capitol Complex Chilled Water System T Improvements
Chilled Water System T (F°)
Prior to improvements, the chilled water T was between 6° F and 7°F
Increased the chilled water delta T from between 6° F and 7° F to between 12° F and 19° F.
Plus, hydraulic modeling of the chilled water system at NYU Medical Center resulted in
the removal of nearly 1,300 horsepower of pumps and a demand reduction of almost a
megawatt. And at Memorial Sloan-Kettering Cancer Center, modifications to the pump
configuration and piping distribution reduced peak electrical demand by 1.2 MW.
