hi many thanks for the video! I was wondering if I can use the hb utci confort map component to make an estimation for temperature levels and so efficiencies of the PV panels that are located at a certain level?
The comfort map is the perceived temperature. But for PV panels the most important aspect is the exposure to the sun. Not the temperature. But you should be able to calculate a heat map just from the surface temperature only. It's an interesting topic.i might make a video.on this.
Difficult to answer this. To a certain degree only, this is because E-Plus does not count things like evaporative cooling or the opposite like heat stress because of increased humidity.... it uses a rather simple way to estimate an influence.

Hi Philip, I've been trying to recreate the results of your tutorial but my final mesh seems to show inverted colors (areas near a building are hotter than the rest of the site). Do you know why this might be happening? Thanks.
Not sure if I understand correctly. That could definitely be true that areas are hotter next to buildings, material, reflection, less wind etc... So they are showing hotter or colder next to buildings in your script...
@@PhilippGalvanDesign Sorry, let me clarify: The shaded areas where the building is casting shadows on should be cooler but they are appearing hotter. Also, I've applied different materials to my HB model but the temperature results for each "room" look the same across all of them even though a grassy lawn should be cooler than asphalt or concrete paving.
Hi Philipp, thanks for these amazing videos! I was looking for something like that since a lot of time. It's great!! Anyway, I'd like to report an error it occurs to me: "1. Solution exception:Number of _values (2490) must match the number of mesh faces (415) or the number of mesh vertices (415)" in the LB Mesh Thershold Selector. I have tried to flatten values/meshes but I can't solve the issue. Do you maybe know how to help me? Thanks!
Hello! I'm having the same problem with you. I'm wondering how you solved it. What's the Graft? and how do you remove it? Thanks..!!!@@alessandrogrossi1568
What is your profession, that you are able to get into this topics quite well? I hope you can use this knowledge for yourself as well. Thanks for your videos.
Hi Martin, I'm a Landscape Designer. I work on Architecture and Landscape Projects at Heatherwick Studio in London. So yes I need that stuff but mainly for early design stages. Normally we collaborate with engineers so they take on this role. However they mostly focus on the Architecture and less on Landscape. That's why my interest in the topic. How about yourself? Hope you're doing well.
@@PhilippGalvanDesign Thanks, interesting. Although climate protection and adaptation are present in every planning hierarchy, I see it as undervalued in many new single family home development designs. Existing knowledge is not converted into action. Density and land value are often not managed sustainably. So far, your videos have given me more of an idea of what's possible than a guide for my own projects. Anyway thanks again for your valuable inputs.
@@martinmuller3250 Very good comment. Yes it's tricky, every project has its own set of problems. I'm still searching for the right idea/project to show how the tools can influence design decisions. There are a few ideas on how but difficult and time consuming because I would need to somehow script a whole series... It's something this channel will evolve to...
please how ti fix this error .....1. Solution exception:Your Model units system is: Millimeters. Is this correct? There must be at least 3 vertices for a Polyface3D. Got 0
I would strongly advise to use meters as unit system. All calculations are done in meter. Regarding the polyface I'm not sure. Seems a problem with the model.
Hi Phillip, your videos are of great help! I was wondering how can we define legend with uneven ranges in this script (as per UTCI comfort ranges). Please let me know if you have a solution. Thanks!
Hi, you can set specific ranges with the legend parameters. There you can set range steps and minimum and maximum value. Check Ladybug extract tool section for the Legend Parameters.
It is difficult to simulate the effect of water on outdoor thermal environment. The present study also shows that the influence of small scale water bodies on thermal environment is very weak. Therefore, for architectural design, the influence of water on thermal environment can be ignored.
Good idea, I will keep it in mind. It could have a tremendous effect. Water absorbs a lot of energy and can have a positive cooling effect. But yes it is tricky to calculate because of humidity. High humidity has a negative effect on thermal comfort. In case the water is very shallow and evaporation is high, it might have a negative effect...(probably in rare cases)
@@kevinyan3208 do you know a tool with wich we could do simulations including the effect of evapotranspiration? I have come over ENVI_MET, looks capable of these things but is quite expensive for students experimenting
Can i check the urban thermal comfort for various scenerios, Like i will change the building height, street width , Can i compare the scenerios afterwards
Hey Phillip, it would be interesting to for you to make a series where you develop your own project and delve deeper in internal and external comfort of the project. You could explain what would be your proposed solutions in order to make the spaces desirable then compare the results in Ladybug/Honeybee/Butterfly.
Yes, that's the ultimate goal. I still need to find the right opportunity. But yes totally agreed. Which project typology do you think would be the most interesting for you?
Hi Phillip, thank you very much for making the video for this specific issue. Following a quick test everything seems to be working fine. I'll perform detailed testing during this week and will report back. Meanwhile, take care & thanks again
@@PhilippGalvanDesign Hi again Phillip. The script works exactly as anticipated. Great, thank you very much for your support on this. Now, I can set up a point of interest (i.e. under a shading structure or a tree) and compare the UTCI temporal profile for this point against a control scenario. Just to expand a bit on my intention with the HB Threshold selector, since I probably wasn't clear on what I am trying to achieve here - similarly to the above, my vision is to have a basic control scenario, then apply a measure to improve the comfort (i.e. position a tree) and then quantify the UTCI improvement. In this case, I am aiming for a summer peak hour. Using the threshold selector, now I can not only see what is the UTCI reduction under the tree, but I can also say what is the area with the reduced temperature at this point in time. Apologies for not being clear on this and that you had to come up with your own ways how to employ the component. Having said that, I think you did a great job - especially by including the averaging over a time series. This way, you added the possibility to evaluate not only for the peak hour, but also for a (lets say) peak day if one chooses so. In any case, now I understand the logic behind the component. Fabulous Generally, I think that the model with the ability to characterize material properties in combination with the annual profile and the threshold selector is a good basis for a powerful tool (I understand that it still has limitations as it makes gross assumptions on wind speed (no CFD) and does not take to account evapotranspirative cooling by trees or water bodies as discussed below. Nevertheless, it still shows trends). I can now compare and quantify variety of scenarios, which I think is very important part of the design process - while some decisions can be based on experience and intuition, others are much harder to characterize. Also, easy comparison of potential solutions (such as optimal placement of trees, species selection, combination with shrubs etc..) makes it much easier to communicate design choices to others. So, thanks a lot again Phillip for the support while developing the script up to this point. I really appreciate the time and energy you have invested into creating the video
My further steps will focus on inclusion of trees in the model, I am hoping to get it working including canopy transparency and summer/winter profile for deciduous trees.. Will report back

I did a video where I combined UTCI with Butterfly CFD, although with Ladybug not HB.
But the method would be almost the same.
Yes please do. Always curious...
