We are planning on installing a whole house fan on a three story brownstone. As several previous posters have observed, almost all whole house fans are designed to vent into the attic. However, given the nature of Bklyn brownstones (flat roofs, no attic), we need a fan that mounts on the roof.

What have people trying to install whole house fans on brownstones found out? We have 3600 sq ft of space we are trying to ventilate, so it needs to be a powerful fan. I don’t think other solutions previously mentioned such as turbines would work in this case.

Can anyone recommend an HVAC engineer that might be able to consult on this?

Thanks for any advice.
