autosizing HVAC in baseline model

Dear Sirs,

I model the baseline case of a project and I need to calculate the capacity
and the other parameters of the HVAC (system 6). If I am not wrong I can
do this by autosizing but I am in DD mode and so I do not have this option.
Do I have to do parametric runs in order to calculate the required values?
Any information regarding this procedure is going to be very useful.
Thank you for the help.

Regards,
Eva

Eva,

I think what you want is to, in DD mode, put the cooling capacity at 0 and the
cool sizing ratio at 1.15 (I think that's what Appendix G specifies). See the
screen shot.

Does that answer your question?

Hi,
thank you for your response. Could you please send the screen shot because
it wasn't attached in the previous email. I know that I have to put 0
capacity for both heating and cooling and 1.25 and 1.15 sizing ratio
respectively but the next steps are not clear to me. Thank you.

Regards,
Eva
