Re: Ventilation
John S gave the example a while back of the exhaust fan is his
workshop. My polling place the other day had an elaborate exhaust system
that seemed extra to me, since the room was full of windows and it was a
pleasant day. Maybe they are practicing for November, when people will be
less happy about cold air. There is this article fro NPR this week that
boils down to "it depends" about small room air filters, which is not what
you're discussing but is ventilation-related
https://www.npr.org/sections/goatsandsoda/2020/09/04/908896132/coronavirus-faq-is-it-a-good-idea-to-buy-an-air-cleaner-for-my-home
I feel that the current system (short duration, masks, open windows)
is the best combination. For my two shifts at the Advent, I have double
masked (4 fabric layers total). I was interested to read that buildings
(in NYC) built in or just past 1918 had such excessive steam heat systems
because they expected people would leave windows open year-round, but
still want to be warm. I am hoping for open windows in public places this
winter, too.

I recently installed an exhaust fan in my house. I'm wondering if we
should consider installing a permanent fan in the belfry to pull air up
from the ringing room, with baffles to minimize bell sound coming through.
Should I work on designing such?
