VAV Induction

Hello everyone!

I have an inquiry regarding VAV Induction Systems. In Architecture Studio Companion (3rd Edition - pg 149), it mentions VAV Induction systems are used to maintain a sufficient level of air movement in spaces that do NOT have a high demand for heating and cooling. Additional sources mention using VAV Induction when there are extreme heat load variations. The damper helps control this and stops cold dumping in a space.

Perhaps I'm reading this wrong, but I'm a bit confused if you use a VAV induction when you don't have a high demand for heating and cooling OR use it when there are head load variations.

Any feedback would be greatly appreciated.

Thank you,
Ashley
