Yes, it's a way to make it more realistic. It's what I did, for now. Thank you!

I have seen this sentence. I don't think it's saying COP is 1. I think it's talking about something like mechanical eff

Sure, Thanks. I think it would be better if it's clearly explained in the documents.

Hi, So I used "ZoneHVAC:IdealLoadsAirSystem" in one simulation case. I have the cooling and heating energy consumption. Just wondering, what's the COP/EER of this ideal air conditioning system? Thank you very much！

Thank you very much. This is really, wow, an air conditioning system with COP of 1, in my opinion, i will consider the e

If COP of the ideal loads air system is really 1, it's unreasonable. In fact, air conditioning system's COP/EER is alway

But the energy consumption is a little different from what comes out of IDF2.

yes, it does have outputs

Are you sure, Mr Horowitz? Can you please double check?

sorry, hang on, I will upload the weather file I used. And yes, the problem didn't show up all the time, like this same

converging problem caused by 'zone group' object Hi, there. I’ve met a problem when I try to simulate a seven-story buil

Well, I compare this failed .idf file with earlier version files of this very same building. I found this error is cause

ah, thank you very much!

total energy consumption by zone I hope this is not a silly question. I'm working on a building model which includes man

Thank you so much! I did check Input and Output Reference, didn't find it. Thanks for your help, very specific and clear

Hi, I wanna ask where can I find specific explanations of variables. I wanna output this variable named "Zone Thermal Comfort ASHRAE 55 Adaptive Model 90% Acceptability Status" The results show three numbers: 0, 1, -1 to represent the status.But I have no clue what does it mean. Where can I find the explanations? Thanks!

What does the numbers mean in Zone Thermal Comfort ASHRAE 55 Adaptive Model 90% Acceptability Status Hi, I wanna ask whe

What does the numbers mean in Zone Thermal Comfort ASHRAE 55 Adaptive Model 90% Acceptability Status Hi, I wanna ask whe

yeah, i didn't set those. Must be the humidity. Thank you so much

Ideal Loads Air System doesn't meet thermal comfort requirement Hi, I'm having this problem with Ideal Loads Air System.

@anchapin yes, I checked,it is what I'm trying to do, thank you for your very valuable suggestion.

Thank you very much, this answer is very clear and specific, I think my problem can be solved then. Thanks again!

Thanks a lot. Do you mean first I need to know the specific dates, then I set the heating and cooling schedule? In this
