[Greenbuilding] state of the art stove/bathroom exhaust fans?

[Alan Abrams]

more generally, what about the role of any exhaust system? how does
depressurization affect other conditions and systems? is there an ERV, and
if so, is it balanced to admit compensatory make-up air? are there any
combustion systems, or fireplaces with imperfect flue dampers?

is it possible to reduce the number of exhaust openings, by collecting air
from individual spaces with a central fan? What about the routing of the
exhaust line; given it will tend to be at ambient conditions, how is the
line insulated, and how well does the damper work? How does the new
requirement for make-up air for range hoods greater than 400cfm come into
play?

these factors may have as much as--or more significance than--the fan unit
itself.

No answers tonight, we've already opened a bottle of Cab.

Merry Christmas to all, and to all, good-night!
