[Bldg-sim] Different versions of eQuest produce different results?

[David Eldridge]

What percent of the energy is for cooling in the before and after, and which one makes more sense?

First though is maybe an error in the earlier version. The magnitude change you are talking about sounds like the original version may have had a small packaged unit running, but not your central chillers.

Hi all,

Is anyone aware of any bugs in eQuest that modify specifically the space cooling energy results? A LEED model was originally produced in version 3.64 build 7130, and when I run it in my later 3.65 build 7154 (without making any changes) version the space cooling increases from 60,000 kWh to 2,300,000 kWh! Note the heat pump supplementary variable also changes, but not by 3,000%.

I noticed that in the PS-H report my chillers are working (in the later version) and in the previous version they are all in 0s. Note nothing was changed, just re-ran in different versions.

I have searched, but haven't found any bugs related to these specific versions. Any thoughts would be much appreciated.

Thanks in advance,
