[Equest-users] Simulation with Baseline model, Thanks for Your Advice. I am unable to figure it out.

[Guoguang Le]

Thanks to all who participat the forum and to this forum itself. How great it is. It gethers such smart and hard working people in one place. I appreciate your time.
I will practice this weekend. I am sure that I will make great progress.
 
Best regards,
 
James

The problem is that the difference between the baseline and the proposed isn’t just a difference in system types, there are other factors involved such as minimum flow rates, pump power, fan power, etc. Read appendix G, all of those criteria need to be implemented in the baseline. The proposed model should match your own design. I don’t think all of these changes could be done within the same model.

Yes, and my experiment didn’t work by the way – must be why no comments were made.  I thought it was working but alas the GSHP plant equipment button is greyed after going back into the wizard. so I suppose there is no way to compare LEED baseline with proposed in one eQuest model?
 
It did “appear” to work.  The geothermal had a higher electric usage and way lower gas consumption – this made sense to me since the geothermal would have pumps & more intricate controls and the PSZ would eat up the gas in winter.
 
Anyway, now I am planning to have 2 model files and use the EEM wizard to rename the runs appropriately.  I will then have to generate my own comparison reports if I want them I suppose.  Had to find percent improvement on my own anyway.  Attached is a simple spreadsheet showing the comparison.  There may be a template for this, I’m just wandering through the energy simulation forest for the first time so any thoughts/feedback would be appreciated.
 
Maybe I need some training…

eQuest uses “Baseline” to refer to your base model, with EEMs in mind. The word has actually nothing to do with either 90.1 or T24. 
 
For example, if you are doing a LEED model and create two models: one proposed and one LEED baseline. Both will be called “Baseline” by eQuest.

To eQuest Expert,

 

I have a question to beg your answer. For an equest model, after I input some data and then run simulation, the report showed "baseline". What does this "baseline" mean? Is it meaning min requirement by Ashrae 90.1, T24,  based on what I just input data or something else? In other words, how to run baseline model by using eQuest? 

I appreciate your time very much! Thanks Lot !!!

Best regards,

 

James Le
