yes for the integrated WSE if the cooling tower doesn't have enough capacity OR the wet-bulb temperature you specified is exceeded you will see some chiller energy. If you have enough capacity in the cooling tower AND the wet-bulb temperature you specify is not exceed then there will be zero chiller energy. You will still have "heat rejection fans/pump energy" in both cases. Hope this helps.

I am pretty sure if you use the pre-cooling tab (not heat rejection), then the cooling towers take care of the load before the chillers. Careful with the outdoor wetbulb temperature input though. Emir

Ah thanks for the clarification.

Thanks David, looking forward to new features :)

David, if the zones didn't repeat and we actually end up with a 1200 zone model, would openstudio continue to be this slow in the future?

2014-10-17 15:10:26 -0500 commented answer why is the Data-Center energy so high in DOE energyplus large office prototype models?

Thanks @DancingDavidE, I guess the point I am trying to make is although 45W/ft2 could be the right value for the cooling load, it may not necessarily reflect the electricity usage of a Data Center. I am also thinking and typing out loud here :)

Thanks Andrew. Really useful documentation. The second part of the question is more on the UPS power. As this graph shows, although UPS equipment is ON all the time, their electricity usage drops significantly after they are charged. (yet still they give out heat). Do you know if UPS equipment is modeled as a plug-load or just a heat source?

Haha Thanks @Amir. @Julien They were added after 2004!

Are UPS rooms included in the Data-Center plug-loads? (whereas they should only be giving out heat, without drawing much electricity)
