Most facilities personnel do not know what is
really happening with their building operations. They can’t
because they see only a tiny fraction of the operational
information that would give them real insights. Today,
optimization happens at a component or sub-system level with
little or no information on how the parts work together. Actual
hourly operating cost data, and any ability to see how control
changes, weather, occupancy, etc. affect costs is simply beyond
most organizations.
This paper was presented at the
2005 World Energy Engineering Congress and was also published in
the June-July 2006 issue of
Energy Engineering Journal. It examines how to use operational and cost
data to optimize HVAC performance. The examples use case study
data from a large hospital in the southeastern U.S. that started
collecting operational data 18 months ago and the impact to
operations has been substantial, to say the least.
