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





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.

Hello Group,
I'm not sure how to run both a Summer and a Winter DesignDay simulation.

If the idf specifies x2 SizingPeriods, i.e.
SizingPeriod:DesignDay, Winter,  !- Design Day Name

AND

SizingPeriod:DesignDay, Summer,  !- Design Day Name

BUT without a RunPeriod or RunPeriodControl object specified

What is actually getting simulated.

When I comment out the one SizingPeriod:DesignDay, the other gets simulated. It's
a) used in sizing
b) for warming up
c) simulated run

Q1) How do I best simulate both days seperately? Can I run x2 run periods (one for each design day) and will they be seperately warmed up?
