Water features in Outdoor thermal Comfort

Is there a way to check the effect of having water bodies and fountains on the outdoor thermal comfort?

I wrote my thesis (partly) on that.

Short answer: Not really. Maybe Envi-Met can do that?
The physical principle is quite simple: the water evaporates -> relative humidity increases -> temperature decreases. That process is well described, but I guess you wasnâ€™t just looking for some formulas.

First you need to calculate evaporation from your water body, which is manageable. Or you need to guesstimate it. I used a CMF for that.
Then you need to translate the evaporation into a change in temperature and relative humidity. As I said, that is in theory quite easy, but it gets complicated when you take into account wind flows and so on. I came up with a method for calculating it for still standing air. If you want high accuracy and a coupling to a CFD simulation, current research points towards transient CFD analyses, which in my opinion is not feasible.

I implemented my work in Grasshopper under the name Livestock. It is possible to download and try out. There is currently no tutorials as Iâ€™m rewriting the plugin to make it more simple and user friendly.

Cheers

Interesting! Thanks for sharing you work @ChristianKongsgaard! Will surely go through it. I somewhat expected this answer.

Thank you for sharing @ChristianKongsgaard.

I am studying the water cycle of a douzain farms in France and was trying to create a ETP soil model as well as a precipitation model. So I am delighted to discover your work on livestock ! Thank you so much for sharing this.

Looking forward for tutorials and userfriendly plugin.
I am going through it !

Hi! @ChristianKongsgaard, thanks for sharing
Iâ€™m new to Python scripting, and i usually only use the â€śgraphicalâ€ť scripting method from GH. I managed to install Livestock reading your instruction here https://kongsgaard.eu/install-livestock.html , and i can actually use Livestock components in GH, but none seems to work. Probably itâ€™s because iâ€™m using Rhino 6.0, while your plug-in is made for the previous version i think. During the installation, i put the downloaded files in %appdata%â€¦Rhino 6.0, and not in the 5.0 folder that you indicated in your guide.
Is it possible to use Livestock in Rhino 6.0 somehow?
Iâ€™m getting into climate simulation and i need a realistic reconstruction of the evapotranspiration effort, so, from what i have read on this forum, it would be great.
Thank you!

Hi @sipicco
I unfortunately havenâ€™t had the time to look at or work on Livestock since the end of 2018. So I donâ€™t really know if it works with R6 or not.
Have you tried this https://kongsgaard.eu/hill-slope-tutorial.html ?
If it doesnâ€™t work, then it might be that you didnâ€™t install Livestock correctly but it could also be that I broke something while updating something else.

Yes, i gave a look at that, but every Livestock component i drop in the canvas gives me this error:

1. Solution exception:Part of the path is impossible to find [â€¦]\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\livestock\components\component_list.txtâ€™

I think itâ€™s eĂ¬because of the rhino version

Yeah that is a Rhino 5 specific path.
Can you hack it by copying the `component_list.txt` to `AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\livestock\components` ?

Hi, Iâ€™m trying to study the effects of plants on Microclimate Simulation, so Iâ€™m very interested in your research. But I couldnâ€™t open your home page link to get â€ślivestockâ€ť. I donâ€™t know if itâ€™s my network restrictions. If you can give me a new link, I will be grateful!

I used to be able to run slope tutorials 2 years ago, but I tried again last week, and I cannot run it anymore. I am not sure of the reason why, but I guess something in the installation process goes wrong. How can we work on that topic to make CMF available in GH ? I really need that stuff for permaculture, flood, and overflow studies, and I am ready to spend time this year to come in developing this kind of tools, but I am not able to manage it all by myself. Can you help us in any manner ?
Thanks

I really wonder what you have shared that but I guess link is broken. Would you check the link that goes to your thesis please?

Hi everyone, I have the same problem. The site is probably compromised.
