If you are writing about venting roof attic areas then powered fans usually are not needed. Heat rises and those spinning ridge "chimney" type vents (sometimes called barn vents)are spinning by the action of warm air rising.
I have a well insulated roof and no ceiling fans. Very comfortable all the time.

Assume the best and ask questions.
