Detailed Edit mode, you can specify the ratio of equipment sizing that you want
for both heating and cooling. So to specify the Appendix G baseline model, you
would oversize cooling by a factor of 1.15 and heating by a factor of 1.25.
Take care to check what the system sizing ratio is set at as well so you don’t
add safety factor upon safety factor. Good luck.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hello,<br>
<br>
As I mentioned previously, I am creating an energy model for a LEED
project. In "baselining" the building, one of the stipulations
of ASHRAE 90.1 2004 is:<br>
"G3.1.2.2 Equipment Capacities. The equipment capacities for the
baseline building design shall be based on sizing runs for each orientation and
shall be oversized by 15% for cooling and 25% for heating" <br>
<br>
I think that means I use "auto-size", but then how do I capture what
that size is and oversize it accordingly? I am guessing that the results
may be in the SIM file. Can anyone provide tips for executing this?
Is there a better way to do that auto-sizing for each orientation? <br>
<br>
Thanks,<br>
Andrew McNamara<o:p></o:p></span></font></p>
