Hi, Jie & everyone:

Thank you so much about your suggestion. You make it more clear. 

Do you have any suggestion about the additional system referred below? 

Exceptions:

a. Use additional system type(s) for nonpredominant

conditions (i.e., residential/nonresidential or heating

source) if those conditions apply to more than

20,000 ft2 of conditioned floor area.

And I heard that the consumption of the garage ventilation system power should be seems as the process load. So it should be the same between the purposed and baseline model, no matter if the garage with heating. Is that right? 

Thanks again.

 

Joey

Is the garage with air conditioning system? I mean heating and cooling. If the garage is just with mechanical ventilation, you should model it as design in the baseline model. If the garage is with air conditioning system(and the heating source is also same), however it still in an office building, I think the baseline system type is the same as the office baseline.

The 3.1.1 is applied to only conditioning system.

Hi, everyone:

I have a question about the system type of  APPENDIX G3.1.1.

As the below requirement. Is that means for an office building with a garage, the garage system in the baseline building can be the same system type with the purposed building . if not, what’s the list for the additional system?

Any suggestion should be appreciated .

Exceptions:

a. Use additional system type(s) for nonpredominant

conditions (i.e., residential/nonresidential or heating

source) if those conditions apply to more than

20,000 ft2 of conditioned floor area.

 

 

Thank you 

 

Joey
