Sentence 5.2.11.2.(2)

Intent 1:

To limit the probability that air distribution systems will serve an excessively large area, which could lead to a lack of aircontrol, which could lead to

• excessive air supply to areas whose instantaneous load can be satisfied with less air,

• excessive air exhausted from those areas, or

• load demand from areas not served by the zoned airflow.

This is to limit the probability of unnecessary fan energy usage and excessive thermal energy transfer, which could lead to unnecessary consumption or demand of energy for heating and cooling, which could lead to excessive use of energy, which could lead to an unacceptable effect on the environment.
