A/C Area 1

[Pavilon]

I have a dispute with our client regarding what will be included within A/C area of apartment's units when calculating loads. I'm using HAP and I considered living area(including study and dining) + wet area (laundry, en-suite,wc,...)
Is there any written code to demonstrate and prove that or that's all is based on engineering judgment?

Thanks

how would you calculate loads for conditioned room which is next to non-conditioned one? you have to calculate or estimate design balance temperature of non-conditioned spaces to have calculations correct.

If your client wants to tell the Engineer how to do the cooling load, have him stamp the drawings.

I said it here in teh past and I will say it again. HAP or Trace are not good software for residential single family type homes calculations (excluding high rise apartments).
You should use manual J calcs fore residential, which substantially under-size equipment for residential (the way it should be).
Hint: If your loads are coming at less than 700 SF/Ton, you are likely oversizing.
