In my experience, installation in rated wood assemblies are accomplished by using radiation dampers in lieu of fire dampers. Much less of a hassle installing them in thin assemblies.

I believe you have a fixable issue given the information you have provided. I also think it is can be achieved for very little cost to the owner - mostly just an O.A. balancing issue as I see it.
I calculate O.A. requirement per ASHRAE 60.1 to be roughly 1,750 CFM for the Dining...
I'm like you guys, never had to deal with something like this other than the normal venting of the shaft and addressing heat in the machine room.
Walkes, the exposure is east facing as is seven (7) levels of continuous glass.
I have an elevator shaft with en exterior wall that is entirely glass. It is in a parking deck of all things. I have never had this scenario before so looking for options on how to treat the shaft. The project is located in the deep south.
The senior dude in the office believes the shaft...
Automated Logic has an online control specification generator that covers a wide variety of system types. I use it quite often as a good starting point then editing it slightly for my particular need.

It will work on either side - but I was taught to place it on the return leg side as to "....always keep the coil flooded.." Whether there is a valid reason behind this, I haven't a clue.

Looks correct to me - just so happens the air flow numbers work out essentially the same (6,000 cfm) for both the radiator and heat rejection to the room. Have an intake louver @ 12,000 cfm with a fan @ 6,000 cfm and call it a day.

As a wise man once told me.... Don't sweat the petty stuff and don't pet the sweaty stuff... Sage advice.
Looking back on my career I do wish I had kept a journal of promises and incidences that were made/happened to me along the way. Memory is fleeting - especially with your direct superiors.
Your estimate sounds in line with the WAG I use - 3w/sf lights & 3w/sf misc. heat.
Good one!!! I follow the same practice! I specify an ion generator (Bio-Climatic is one) on the discharge side of the air handler. Even had a client request the same be installed on the exhaust system serving...
Yep, you are correct - been buried in the codes since I can remember - but rarely seen it enforced (I can only recall getting "hit" by it once in my career).
Here is IMC 2003 take on it:
I am not a big fan of this code requirement where general exhaust is concerned.

When I am making a quick estimate on CFM's required, I use 300 cfm/ft to get a ballpark number. 98% of the time I send the kitchen lay-out of equipment under the hood to trusted kitchen hood reps for recommendations. Keep in mind there are a number of "low flow" hoods available on the market...
As stated, I use ASHRAE guidelines to determine the heat generated by each specific piece of cooking equipment located not only under the hood, but ancillary equipment (such as refrigerators, ice machines, etc.) located in the kitchen. One I have tabulated the heat rejection numbers, I usually...
Wow - haven't visited the boards in a while and stumbled across this one. Read it from beginning to end.... Don't envy you Cass...not one bit. A slippery slope you have slid on.
From what I have garnered this is a condominium project some where in Cali. One that was started by one developer...
IMHO, option No. 1 would be a no go. 12 years on anticipated 15 life cycle doesn't make since to repair. Three reasons for me come to mind, age, R-22 and the third, its a RUUD (not a huge fan of theirs).
While a zoned 5-ton system looks good on paper and would be cool to show off to your...
