<div>Hi Bill,</div>
<div> </div>
<div>I don't recommend using design days instead of the weather file at this time. I have heard in the past that the HDD and CDD schedules that are automatically generated don't actually work for sizing if you don't live in California. I can't remember the exact details of that rumor but perhaps someone else will. I also have heard in the past that it is better to use the weather files as using the design day method tends to underpredict the size of the systems. That's all we need! More hours loads not met, yikes!!</div>
<div> </div>
<div>So it would be a significant amount of extra work for no real gain. </div>
<div> </div>
<div>Cheers,</div>
<div> </div>
<div>Carol<br><br></div>

<p class="MsoNormal"><font size="2" face="Arial"><span style="FONT-FAMILY: Arial; FONT-SIZE: 10pt">I have been letting eQUEST determine baseline equipment capacities using the weather files selected by the wizard, rather than creating 99.6%/1% design days as allowed by G3.1.2.2.1. Does anyone recommend using design days for LEED/Appendix G baselines? If so, how do you determine DRYBULB-RANGE, or do you set it to zero to run the same DRYBULB-HIGH temperature 24/7/365? Does the design day method typically maximize baseline energy consumption compared to TMY/TMY2 weather files?</span></font></p>
