Commissioning
All of our design efforts are of no value if the IAQ system is not con-
structed and commissioned as designed. See the section on commis-
sioning in Chap. 14. This must include training of maintenance per-

sonnel in the maintenance and operation of equipment which, since
these are new concepts, may be considered unusual or even exotic.
21.5.2
Maintenance and use
Even though the IAQ system is properly designed and installed, and
is functioning, it is essential that it be competently maintained and
operated. This should result from the training at commissioning. One
of the designer’s duties is to convince the owner of the necessity and
value of these things. It is not always an easy task. One valuable
argument is the research data which show that the cost of sick, un-
well, or unhappy workers is much greater than the cost of doing the
proper maintenance and operation. The owner should also be re-
minded that poorly maintained equipment will not provide the ex-
pected environment.
