I’m using your model in the framework of my PhD to produce air temperature maps and aim to compare the simulated maps with measurements made by ground stations. To be sure to use the model properly, I have few questions.
First question: I would like to know if the calculus I made for the parameter VerToHor is correct.
I referred to the definition “verToHor: Vertical-to-horizontal urban area ratio (facade area/urban area). The resolution of the urban area that I am working on is 200 by 200m.
1) I calculated the total length of facades within my area
2) I calculated the total facade area = total length of facades x average building height (for the same area)
3) I calculated verToHor by dividing the facade area by the area of my zone, which is 200x200m
Second question: in the epw file, I set the dates in UTC and in the header I defined the UTC zone as +0. This choice was made to avoid problems with the daylight saving time change. Does it seem correct to you?

Here : https://urbanmicroclimate.scripts.mit.edu/uwg_parameters.php#urbanArea , they talk about a weighted average building height. Thus, I was wondering if this ponderation step should be added in my verTohor computation.
Second question: in the epw file, I set the dates in UTC and in the header I defined the UTC zone as +0. This choice was made to avoid problems with the daylight saving time change. Does it seem correct to you?
Thank you in advance for your help with this.
