Retro-commissioning is the
missing link for improving
HVAC plant performance.
Commissioning plant systems–such as boilers,
chillers, towers and pumps––used to be a one-
time event. But in the quest for ways to keep
building performance high and operational
costs low, on-going and retro-commissioning
maintenance is becoming part of a best-
practices regimen. Modern Building
Automation Systems (BAS) can provide some
of the benefits of on-going commissioning.
The self-tuning controls of BAS systems often
cover up poorly operating buildings, however.
So both buildings with and without BAS need
regular inspections and calibrations. If the
building equipment was never properly
commissioned in the first place, a retro-
commissioning is important to evaluate,
baseline and make changes to maximize
system efficiency. Older buildings with fewer
or older controls require more footwork,
measurement, analysis and often upgrades.

Calibrate critical sensors wired to building
automation controls. Sensors that are even a
few units out of calibration will cause systems
to consume excessive energy.
Log temperature, pressure and humidity
values and compare to ASHAE or other com-
fort standards.
Check air, water, and steam flow rates
with data loggers or field calibrators. Change
in flow rates could indicate a fouled heat
exchanger, piping or pumping problem.
Check air, water and steam pressures
and compare to BAS equipment readings and
design values to identify efficiency loss.
