On the other hand, under the technical commissioning model, the CxA not only prepares the the functional performance
tests, but either performs or helps the installing contractors
perform the tests—and then documents all test results that do
not conform to the OPR document. The technical commissioning process also requires the CxA to assign responsibility
for corrective action, provide practical recommendations to
help resolve issues, and follow all issues until they are either
corrected or accepted by the owner.
Process completion. When process commissioning is complete, the CxA presents a report to the owner and says, “This
report verifies that the building has been commissioned.” But
this type of reporting does not ensure a fully functional facility;
it only verifies that known deficiencies have been documented.
On the other hand, technical commissioning process enables
the CxA to look the owner in the eye and say, “Your building
is complete and it functions as designed. We have personally
verified the design and construction process through a stringent testing process of every building system. We have proven
to ourselves and to your staff that all of the building’s components and controls function as intended.
“In addition, we have verified that that all controllers react to
setpoint adjustments in a timely manner, produce the desired
results, and are stable. Finally, we have collaborated with the
construction team to resolve any issues that emerged during
testing. Here is our report, which clearly documents our tests
and the building’s full conformance with the OPR document.”
Technical Commissioning Model
ASHRAE, NEBB, and other associations are in the process of
developing improved guidelines and standards that more closely
match the technical commissioning model. And at the core of
these new standards is a comprehensive, hands-on approach to
testing and verifying the proper operation of a new building.
It’s the unswerving commitment to real-world testing and
verification that enables the technical commissioning process to produce buildings that truly meet owner expectations.
When properly implemented, the technical commissioning
process represents a major step toward ending the problem of
under-performing buildings once and for all.
