Help me, O'bewon, you're my only hope.
I'm just a reasonably competent bystander, hence my
call out to the experts.
The situation I'm facing is that my apartment complex has
an enclosed, large (100 or so) car garage with a "lift door"
at one end. (It's also got an upper level with a separate
roadway entrance, and that one uses a remote controlled door).
The garage is heated to a nominal 60 or so degrees, using
low pressure steam from the main powerhouse that's fed
into a half dozen or so blowers. We're in NYC so this
means heating is needed a decent portion of the year.
My question, and I'm hoping you'll treat me gently, is
that the garage door is generally left open full time.
(There's a staffed attendant room just inside, which has its
own walls, heating, and a door into the main garage).
There's got to be a huge heat loss issue here, but I'll be
honest and admit I don't have the slightest clue as to
how to calculate it. (I'd have no problem with working out
the numbers for a wall, but I can't even guess at how to
handle an opening like this).
Could anyone give me a pointer to what the figures would be?
I'm just looking for a rough enough number so that I can
tell the management to get a "real" one - which I'm 99 percent
sure will come to teh conclusion that we'd be better off
keeping the door closed, giving everyone remote controls,
and even adding some more windows and tv monitors to the
The opening is about ten feet wide by eight feet high. There
are walls extending out another fifteen or so feet on each
side, and the garage itself is loosely sealed masonry (cinderblock)
with a bunch of vents scattered around.
In other words, there's no major breeze going through that
doorway, but clearly there's lots of mixing.
(Of course when there's a big wind, etc., etc.)
Thanks for your help.
