EXHAUST FANS
Does anyone know about installing a roof exhauset fan to draw out the heat. You see it in the suburbs, it would have to be on a flat roof but is it done here ?

Vinca –
How would you adapt this for use on a flat roof?
Whole house fans and/or attic fans can be found in many older peaked roof houses in Brooklyn. I’ve given some thought to these myself for a building with flat roof, but only begun to look around and research whether feasible. Here’s one product that seemed promising: http://www.airscapefans.com/collections/whole-house-fans
see them often done here in commercial buildings as a smoke evacuation system to be used by the building’s fire safety staff after a small fire. Same principle as what you see elsewhere. Heating, ventilation, air conditioning folks can help.
I am not sure I would install one in areas where there may be a lot of automobile traffic. If I remember, these things I’d seen in residential areas in the ‘burbs, pulled air in from the (unfiltered) windows and here in the city that might include a lot of auto exhaust and the dust from brake linings, etc.

People have posted about this before. If you search in the archives you should be able to find some recs for HVAC people that had installed such units. I grew up in MD, and my parents had set this up, but it seems to be less common here. Lack of attics and flat roofs are one reason, but it apparently does work well.
Knock yourself out. They’re everywhere. HVAC guys.
