color:#1F497D'>I’ve found it’s very difficult, if not impossible,
to control in the actual building, especially as your slab thickness increases.
The slab can’t cool at night and heat back up fast enough to get any
meaningful comfort control and energy savings. A controls contractor might try
it if there’s a secondary heat source (probably just an 80% efficient
furnace in situations like this), but normally they just get overwritten to a
constant temperature. If you have someone who can spend a good chunk of time
commissioning it, you might be more successful… Has anyone had better
luck with this than me? <o:p></o:p></span></p>

I’m not sure what the exhaust requirements are). You may even only need a
single CO<sub>2</sub> sensor, although it will make control system selection a
little more interesting. Avoid in-slab radiant – night setback will be
important. An energy recovery unit may work out as well (~5 year payback?),
considering the high occupant density, cold winters, and humid summers
(Michigan makes you appreciate the blue sky). <o:p></o:p></span></p>
