Rehabilitation of Secondary Heating and Cooling Systems - Case Study
Abstract
Continuous Commissioning (CCSM) was performed
on the Texas A&M Large Animal Hospital in
October 1996 and as a result, significant savings were
achieved. Subsequently, the building chilled water
and hot water energy consumption increased, and the
occupants complained about discomfort problems
due to later building operational changes. Most of
these problems were caused by control systems in
individual areas that were improperly maintained so
that coils or other components were operating wildly.
When optimal building operations are changed or
degrade over time, follow-up CC measures must
adapt the systems to maintain efficiency. This
degradation may be due to changes in building use,
control programming changes, component/sensor
failure, or system controls by-pass or override. This
paper intends to present the circumstances
surrounding this investigation and the subsequent
measures taken to correct the problems.
