"...very instructive to see how issues in one part of the system
create problems in another. This is the clearest and best
documented description I’ve seen of a problem migrating through
the ENTIRE system."
– comment from peer review
When commissioning buildings, it is
important to extend the scope of ongoing analysis to understand
the interrelationship among central plant, secondary system, and
terminal system operations. Commissioning isolated components of
the overall system can lead to compensating for poor operations
elsewhere, masking the real root problems. It is very easy for plant operations to impact AHU performance, or VAV controls to ultimately affect the
central plant. In the worst cases, efforts to reduce energy can
lead to a net increase in consumption and cost due to the impact
on related systems.
This paper was presented at the
13th National Conference on Building Commissioning
in May 2005, and is published in its proceedings. It examines how to use operational and cost
data to analyze a complex series of interactions involving the
chiller plant, secondary pumping, air handler, and VAVs. The
examples use case study data from a large hospital in the
southeastern U.S.
