Adjusting HVAC in rooms with a lot of people is very difficult...

Each person puts off around 600 BTU's of heat! So if you fill a room with
people in the dead of winter, you may actually need a bit of cooling, not
heating!

They have the same problem in large computer rooms filled with electronic
equipment. It may be 20 degrees outside, but in the computer room they have
the A/C going full blast keeping the room cool.

The twenty year old building I attend services. Cinder block
walls, flat roof. The heat is natural gas, 80 percenters
(induced flue draft). The building has seven zones. Plus,
three offices have a mini split.

The problem is that three rooms are too hot. The primary
(kids class room) is in zone 6. Sometimes it's too cold, so
they push the thermostat to occupied. And much of the time
it's too hot, and so they open the windows.

The library with the copier is too hot. And a computer, both
of them throwing heat. I don't think they have a laminator,
or other heater. Could be in zone 5 or 4, not sure. If it's
zone 5, the thermostat is down the hall and around the
corner. If it's zone four, the thermostat is around the
other corner and down the other hall.

The nursery is probably in zone 4. They have two windows.
They typically open the windows to let the heat out.
Thermostat is around the corner in another room (the other
room has a copier right under the thermostat).

I havn't found any dampers, yet.

Any ideas how to keep everyone comfortable? Windows open is
a security problem because the teachers usually forget to
reclose them.
