[EnergyPlus_Support] Re: What will the weather file override?

Thanks. I see what you are talking about now. I failed to notice that economizers must change (although insulation and windows are the same). I will definitely need to take that into account. The EEFG gives the option of including an economizer. Does the standard override that choice? Are does my decision override the standard?

But that does not appear to impact the standard requirements. I ran both cities through EEFG and double checked by looking at the 2004 standard to make sure. But yes, different climate zones will make a huge difference. That is why I am running an EEFG for a city in each climate zone to get the correct building design for the zone and then changing the location within that zone. I am trying to find a faster and more reliable way to rerun each location because running it online takes a lot of time and is much easier to make a mistake.

I would like to change the location characteristics within that climate zone (e.g. Phoenix to New Orleans) to run the same simulation in a different city. What parameters in the IDF file will be overridden by the weather file and what will I need to change by hand? From what I can figure out, the weather file seems to only override the Site:Location but I still need to input SizingPeriod:DesignDay and Site: GroundTemperature for the simulation to run. Am I correct? Or is there an easier way to change the location characteristics? Also, are there other parameters that I need to change that I am forgetting? Thanks.
