In the old archived Emails I ran across a message saying Attic fans are
not economically warranted.
No electrical $/ KWH was mentioned, nor was the location, or the
choice of blowing or suction operation. Combinations of location and
operation have produced measureable differences in the Sterling.tmy
climate.... On a gable roof house facing 150 to 210 deg mounting the
fan on the East gable and blowing in works best. As a second tier
effect a suction fan used in a house with an interior heated space attic
access can have increased air infiltration if the hatch is not well
sealed - and that is probably the warmest air in the house.
Has anyone studied the effects of running an attic fan operated B or S
on attic located flex return air ducts during air conditioning season ???
Has anyone studied the changes in air infiltration from using foil
backed sheet rock in the upstairs ceiling only.......
Any information or pointers would be appreciated.
Thanks,
John R Ross P.E.
