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

The moisture sub-zones are significant, e.g. see section 6.5.1 in 90.1-2004.

Actually based on ASHRAE 90.1-2004 or 2007, Phoenix and New Orleans are in the same climate zone. They are in different sub-climate zones. 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.
