This case study provides a close-up view of the first six
months of using EnergyWitness™—from installation and initial data
collection to discovering, fixing, and validating a variety of
issues. It takes place at a large hospital in the southern U.S.,
and addresses operational problems, comfort, and engineering design.
There are inefficiencies found throughout the system, including the chiller plant, distribution system, air handlers, and
terminal boxes. In all, we’ll see more than
$265,000 of annual cost savings quantified and verified through
the data, as summarized in this table.
