Ciao all,
I setup a couple of emonTH to measure temperature and humidity inside and outside home.
Now I wish to represent thermal comfort with a synthetic visualization like "standard" comfort representation of relative room humidity vs room air temperature:
Any idea on how I could create similar visualization with emoncms ?
Thanks in advance !
Regards,
Emiliano.
Re: Thermal Comfort Visualization ?
Hi,
Great idea !
I think it is not possible now to draw such a XY graph using the available visualization in EmonCMS.
I think it is worth developping a specific EmonCMS module to draw that kind of graph and also a graph about the adaptative comfort, also known as Brager's graph .
I'm busy now, but I can do it in November as I have already done similar modules.

Re: Thermal Comfort Visualization ?
+1 Great idea
Re: Thermal Comfort Visualization ?
+1 really good idea. nice one!
Re: Thermal Comfort Visualization ?
Great idea, thanks Eric.

Hi,
Thermal comfort is a very subjective concept and it is not related only to humidity and air temperature. So, I suggest to put several configurable thermal zone on the XY graph. I would rather do a XY graph with themp and humidity than a psychrometric graph which is harder to read ( and to code ...)
I will start that dev beginning of November.
Any idea welcomed !

Some literature about thermal comfort zone :

Thanks Eric !
Do you think it would be possibile to include a background image To the XY graph ?
By default it could be the following:

Re: Thermal Comfort Visualization ?
Hi,
I will include several thermal zones. Some default zones like the one you mentioned and also a custom zone defined by the user. For each, a tick box will show/hide the zone on the graph.

Re: Thermal Comfort Visualization ?
Wonderful Eric ! Really thanks.
Re: Thermal Comfort Visualization ?
Ciao Eric,
just curious if you started development.
Thanks,
Emiliano.

Hi,
Attached is a first draft.
I named it "comfort module" but keep in mind that the internal temperature and the relative humidity are only two of the six parameter involved in the thermal comfort : air temperature, mean radiant temperature, air speed, humidity, metabolic rate, and clothing level.
When using those XY graphs that only deals with temp and humidity, you must choose a comfort zone that take into account the others 4 parameters. I put 3 pre-defined comfort zones that corresponds to some standards : ASHRAE (US) and COSTIC (FR). One can see that there are really different ... Thermal comfort is also a very subjective/cultural matter. So, I also added two custom zones that you can define using the CBE thermal comfort tool.
Let me know.
Eric
EDIT : to install this module :
1. unzip the attached archive into the driectory xxx/emoncms/Modules
2. Log in your emoncms server as admin.
3. Go in the admin section (top right corner)
4. Click on the "Update and check" button.
Re: Thermal Comfort Visualization ?
I didn't implement the adaptive comfort graph as it take into account the operative temperature which is not possible to evaluate easily.

Re: Thermal Comfort Visualization ?
Thanks, wonderful !
How can I sue it on emoncms.org ? Any plans of deployment on it ?
Thanks again !
Re: Thermal Comfort Visualization ?
Hi,
You can install this module on your own EmonCMS server :
1. unzip the attached archive into the directory xxx/emoncms/Modules
2. Log in your emoncms server as admin.
3. Go in the admin section (top right corner)
4. Click on the "Update and check" button.
Alternatively, I guess you must ask Trystan to install it on emoncms.org.
