Remove humidity comfort band or add reference #271

Closed

Description

@mairaUSYD

Is your feature request related to a problem? Please describe.
Humidity limits have been removed from ASHRE 55 as there isn't an stablished limit for it, allowing thermal comfort to occur even under high humidity. Maybe there is evidence to define a lower limit, which involves direct health risks. The documentation does not provide reference for the proposed limits.

Describe the solution you'd like
My suggestion is to either remove this comfort range for humidity or include references in the documentation to justify the indicated values.

Describe alternatives you've considered
I consider either applicable, but otherwise more information or reference studies should be provided in the documentation to justify these limits.

Additional context
Students use the platform a lot and reach very misleading conclusions about their climates by analysing this graph out of context. The UTCI is a better way to assess the effect of humidity combined with other variables. My role is to further explain but having appropriate references and models make it much easier.

    @t-kramer @giobetti @stefanoschiavon what do you think we should do? Below is a image showing the relative humidity comfort band but in my opinion this should be removed.

    @FedericoTartarini and @mairaUSYD, it is based on ANSI/ASHRAE Standard 160 Criteria for Moisture Control Design Analysis in Buildings. It is not for comfort. It is not for thermal comfort, but for other reasons (mold, static electricity, skin comfort, etc). I do not have a strong opinion on this. I would be okay with adding a reference to the standard 160.

    Thank you Stefano for the clarification. Yes, I think we need to add the reference to the standard.

    So, I guess two changes are needed:

    1. Adding the standard reference to the documentation and eddition the text
    2. Changing the name of the grey area in the graph to Humidity limits for moisture control or something like it

    @t-kramer could you implement the following change:

    1. Adding the ASHRAE standard reference to the documentation
    2. Change the name from "Humidity comfort band" to "ASHRAE 160 humidity range"

    @stefanoschiavon @FedericoTartarini @mairaUSYD This has been taken care of as an update to PR #273 (see screenshot). I also adjusted the documentation text accordingly. Everything will be deployed with the next merge of development into main.
