Hello,
I am modeling a bulding where wine is made (don´t know how to say it in English, sorry),
the thing is that there are many spaces in the project that have AHU just to process or store the wine under certain conditions of temperature and humidity.
I have some doubts about how to model this spaces:
1. I assume they are process loads.
2. If this assumption is ok, I would need to include the AHUs power inpunt and it´s schedule both in the Baseline and the Project buildings.
3. On the same line of thinking, this will appear as a "Process Load #1".
4. If the previous assumption is wrong, I have to model de project building as it is projected and the baseline building with it´s corresponding air conditioning system, and it will be one more system, NOT A PROCESS LOAD.
I will appreciatte any dicsussion on this,
thank you,
Paula

A winery!
If these system are only used to condition the wine and not for any people in the spaces then they are process. However, if the conditioning also serves the people in these spaces then they are not. In this situation I think they are not exclusively process so model the Proposed as designed and The Baseline according to Appendix G.

Thank you for the data!!, now I know what I am simulating!,
Just one more comment, air consitioning conditions are not intended for the people there to be comfort, but for the wine to be maintained as it needs, temperature set point about 60 ºF and relative humidity about 70%.
Does it still apply as NO PROCESS?
Thank you,

Sounds like they need a basement (or cave) which is where I store my wine.
I will double check with the engineers in my office and get back to you.

Actually they bottled the wine and store the bottles in this place,
A very good one I have to say.

What is the wine?
Given the conditions you indicate we do agree that this is a process load. The conditions are clearly for the product and not the people who are periodically in the space. Sounds basically like a high temperature refrigerated warehouse.
If they only had a cave they could just get rid of this system and save energy!

Thank you Marcus,
We have every kind of space, we have a cave, we have above grade buildings where they bottled and store the grapes/wine, we have everything in there,
I will do as you say, and maybe I will ask you something again later, regarding this same issue.
Yes, the wine is very good.

Perhaps I was not clear - can you share the name of the winery? I like good wine and happily answer LEED User questions in exchange for good wine recommendations! :-)
Good luck with the project.

Hello,
Would it still be PROCESS LOAD if the items were art pieces (does it matter)?
I'm currently modelling a museum and there are several warehouses (I guess people occasionally go there, but I'm guessing that they aren't occupied spaces) that have strict temperature and humidity setpoints in order to maintain the adequate conditions for the art work.
In this case, maintaining temperature and humidity levels in the Proposed and Baseline for these spaces is likely to consume diferente amounts of energy (due to different envelope and lighting levels). Wouldn't this cause different process energy consumptions in the Proposed and Baseline buildings?
Sorry for the "intrusion", but the theme seemed adequate for my question.
Thank you all in advance!

In your case I am not sure you can make the case that this is a process load. It is not about what the space contains. It is about the temperature and humidity settings. If they are significantly different than the setting for space conditioning for humans then it may be considered process. Sometimes you can get some savings related to a space conditioning process load due to its interactions with the other building systems.

Hi Marcus, thanks for your response!
I can understand that this won't apply to exhibition rooms (regardless of the art in exhibition). But this applys to warehouses to?
The temperature setpoints of the warehouses are around 23ºC, except one of them that is for 18ºC. Would you still advise me to model as REGULATED?
Another important question that came up: some toilets / locker rooms are served by 100% outdoor air handling units. The 100% OA AHU's aren't controled by space temperature setpoint , but by a supply air setpoint (air supplied at a minimum temperature of 20ºC and a maximum of 25ºC).
How should I model this in the Baseline building?
Thank you all in advance!

Yes it is probably still regulated, especially the higher temperature one. As I understand the storage of art they also usually have strict humidity requirements too. I don't see an advantage to treating it as process so I probably would not do so.
With identical set points.
