2.1 MAIN DEFINITIONS

Figures 1.1, 2.1, 2.2, and 2.3 will explain the main terminology. These tech-
nologies and systems are described in technical details in Chapters 7 and 8.

2.1.1 Zones
Typically, industrial premises have, in one space, zones with different ac-
tivities, which require different target levels for the indoor environment
and its control. These target levels may be determined for the whole area
or locally. Also, often only a part of the space needs to be controlled. In
addition to the main controlled zone, there may be one or more local con-
trolled zones with targets different from those in the main controlled zone.
For example, machines equipped with electrical components require a very
clean and accurately controlled indoor environment, while the unoccupied
zone near the ceiling needs only roughly controlled protection against
structural damages.
In industrial premises the target levels of indoor air quality, as well as
other targets (e.g. emissions), shall be specified zone by zone.
