cycle of the production process is illustrated in Fig. 3.1. Also, in Table 3.1 short
descriptions and lists of tools for different tasks are given. Some of the tools are
already in use, even if some of them are still missing from the engineer's tool case.
It is important to understand that the results of the design process are
what mainly determine the ventilation system performance with all its conse-
quences. Thus, it is necessary to build all the life cycle targets into plans. In or-
der to ensure the transfer of these targets from the plan to the actual product,
commissioning, operations, and maintenance plans should always be included
in the design work. The value of proper design and commissioning will be
paid back when process modifications are made during the operation period.
One essential item in efforts toward optimal industrial ventilation is a com-
mon understanding of the design: design methodology.
The design methodology is a description of a technical design process that
covers the whole lifetime of the production process. Most decisions concern-
ing industrial ventilation are made at the design stage, and are reflected in
construction, operation, maintenance, service, etc.
