what recommendations should i give to client?
(OP)
i did some heat load calc for a structure that is 100x50
it was a warehouse converted into night club with 284 occupant load.
bare walls, regular doors.
the existing ac system is two 7.5ton units.
this is the calc results:
220k btuh heating
636k btuh cooling

RE: what recommendations should i give to client?
If the client doesn't want to replace the HVAC system, gently tell him that his club will quickly gain a reputation as being hot and stuffy and it won't be long before his clients go elsewhere.
RE: what recommendations should i give to client?
i think anyone could figure that one out.
I suppose this question is better suited for someone local who knows what would be a better design (since the HVAC unit isn't the only thing that needs updating.)
RE: what recommendations should i give to client?
I don't know the background of your client or his experience with property development.
Since you will need to replace the HVAC system in its entirety, you can go with just about anything you want.
I'd hesitate to go packaged RTUs, not without a thorough review of the structure. (maybe a bunch of small ones; I can almost guarantee 2 big RTUs will be too heavy for the roof).
Lots of outside air means lots of exhaust; this will make it a good project for energy recovery.
A separate system for the administration area/offices is recommended.
I'm kinda shooting in the dark here. You haven't really given us a lot of information about the project or asked a very clear question. It almost sounds like you need to hire a local consultant to help you out.

The HVAC system needs total upgrade and re-design.

284 heads at 150W/head --> 12 tons
5000 SF at 1 ton/500 SF --> 10 tons
so more like 22 tons.

RE: what recommendations should i give to client?
i wanna say yes. more people require more cooling.
that's basically the issue to which i was getting. which is why i asked for recommendations that could be given, not to detail out specifications for this project.
i'm looking for general information, not anything specific
RE: what recommendations should i give to client?
thanks for the link.
Yea, i thought 53tons seemed pretty high. Even after adding insulation for compliance with code, i still need 45 ton.
I'm using manual M calcs, not a rule of thumb tho, so the 1 ton per 500sqft would be way off.
With this load i see that there really is no way around keeping the current system. I suppose it's really a question for the client now. does he want a whole bunch of units or swap for really big ones (and potentially require more roof support due to much large unit).
RE: what recommendations should i give to client?
I'm confused by you - your post history makes you look like an electrical engineer, but you're down as structural and now verging into HVAC design??
A couple of tips here...
Add more information. I mean you ask for recommendations with:
No data
No background to the issue
No breakdown of your calculation
No thoughts of your own
So you can't really expect too much here.
As you say the answer is pretty clear - the HVAC system there isn't big enough. Get a bigger one. What else is there to say??
"Night club" is very vague - does it serve food, does it have a load of hot and sweaty ravers, what's the outside temperature etc etc The post referred to gives some idea of the considerations and variance in the answers.
Good luck in your design and if you follow the tips above, eng tips can give you lots of useful information.
The quality of the answer is normally directly proportional to the quality of the question / OP.

There are lots of things to consider when designing an HVAC system not just capacity; from OA requirements to system type to air distribution to sound levels to costs to name a few.
There is a reason we are advocating you hire a local mechanical engineer. You need a proper survey of the existing building. Then coordinate a meeting between yourself, the client and your mechanical engineer to discuss options.
