[Bldg-sim] Cold Storage

[Jim Dirkes]

Dear Robert,

I am now preparing a model of a supermarket in E+ (for the first time J) and have most of the pieces in place.  So far, so good.

If you have not used E+ previously, you’ll be climbing a steep learning curve for the program itself in addition to using a fair number of the more sophisticated features – consider carefully whether your schedule and budget allow it!

I use DesignBuilder v2 for the building geometry and materials – and it works very well. The new version (v3) appears to be very powerful and may allow you to shorten that learning curve dramatically.  I don’t know if they’ve incorporated refrigerated casework…

 

p.s., Don’t underestimate the time and effort to corral all of the casework energy data.  In my 50,000 sq. ft. store there are over 50 pieces of casework on multiple refrigeration circuits, each of which has a unique COPs. Also, you must identify and quantify casework:

·         fan power

·         lighting power

·         anti-sweat heaters

·         sensible and latent case credits and 

·         defrost method, timing and energy source…. 

·         and if you are involved with a LEED project, the Proposed system will likely be different than Baseline.  

 

Whew!

I thin k E-plus is your best fit. I don't think E-quest can do it because the minimum indoor temp can not be set below 55F.  I have done something similar before in E-Plus and it worked fine.

This question has been asked before, but I can't actually find an answer 
anywhere.

The question is basically what simulation tool can be used to model cold 
storage?

A supermarket is a good example of cold storage.  I have read that 
EnergyPlus has numerous features to model supermarkets, including cold 
racks and lots more.  But I have also read that EnergyPlus is 
text-input-only and a graphical user interface is advisable.

I have never used EnergyPlus.  I have used EnergyPro and E-Quest.

Do any of you EnergyPlus gurus out there recommend EnergyPlus for 
supermarkets and further do you recommend a graphical interface?


Your thoughts are appreciated.
