Re: [EnergyPlus_Support] How to run DesignDay simulations - Summer and Winter

[Linda Lawrie <linda@xxxxxxxxxxxxxx>]

How ever many design days are in your input file get
simulated (used for sizing at least) with each getting the warmup
performed.

If you only do sizing and not "perform sizing periods", then
both are used to determine the sizing and neither get actually
simulated.

You can have as many Sizing:DesignDay objects as you want.
