[Build] Ventilated area at NB?

   i recall a couple of issues re the plan for venting 
the entire noisebridge space: 
* the plan was to draw in from the eastern windows 
despite the idea that the wind blows from the west and 
creates a low-pressure area at the eastern surface of 
the building exterior. 
   note that airflow in the space comes from the western 
windows and up the stairs from mission street, sometimes 
quite strongly. i'm not aware of any time that air has 
naturally came in from the eastern windows and out the 
western windows. 
* the motor that was suggested to drive the venting 
system was powerful, sufficient to do the job, but at 
the cost of a lot of electrical power, i.e. potentially 
raising our PG&E bill significantly. 

   currently it seems that the little fans for the bath 
and toilet rooms and the darkroom will draw out of those 
areas and vent to the eastern windows. 
   if, for example, the "dj booth" can be used as a 
"stinky fumes booth" for coating projects and other, a 
small local fan that draws out of that room and vents 
out the eastern windows would probably be sufficient.
