Re: [EnergyPlus_Support] Autosizing HVAC and peak load



You could lower the outdoor temperature in the design day object. Keep 
in mind that it is OK to not reach the peak load on a few days of the 
year so that the HVAC system does not need to be sized larger than 
needed for most of the year. You can also look at the number of heating 
hours not met to get an indication of how often this is a problem. 
Meeting 95% of the load on the peak day sounds reasonable and only a few 
10s or low 100s of heating hours not met also seems reasonable.
