onent are experiential or location specific. For example: humidex has been derived and widely used in Canada.Also both humidex and discomfort index should be used in in-shade conditions.For universal applications and locations, you should concentrate on either PET or UTCI (this is what "Outdoor Comfort Calculator" component is based on).
I have found out, that for instance - OutdoorComfortCalculator - which considers temperatures of 9-26 and other factors, gives the % of comfortable time outdoor for instance in Kenya in Africa (high temperatures and humidity) 55%, whereas within the same .epw data and some additional factors added to the Thermal Indices component, the "humidex" or "Discomfort index" give a result drastically lower, I think it was even 1-5% comfortable.How is that?
Yes, this is one of the issues that I have with UTCI index: the authors wanted to make it as an index applicable in any type of climate. To create the UTCI comfort categories a number of data has been collected from different locations (for hot humid climate, it was the data from Madagascar. I may be wrong on this). This resulted in universal comfortable range of 9 to 26 C which you mentioned. How would the people in Madagascar perceive the feel like temperature of 9 degrees as comfortable is beyond my understanding.Thermophysiology of a human in Madagascar, and in Poland is the same. However their acclimatization is quite different, which raises the issue with the upper universal comfortable range. In general people who live in hotter climates have a bit higher tolerance to high temperature than those living in continental climates. And vice-versa: their tolerance to lower temperatures is lower than the tolerance of the people from the continental climates. Here is a comparison of the UTCI - PET stress categories:
UTCI
all climates stress category
above +46 extreme heat stress+38 to +46 very strong heat stress+32 to +38 strong heat stress+26 to +32 moderate heat stress+9 to +26 no thermal stress+9 to 0 slight cold stress0 to -13 moderate cold stress-13 to -27 strong cold stress-27 to -40 very strong cold stressbelow -40 extreme cold stress
PET
(sub)tropical humid climate temperate climate stress categoryabove +42 above +41 extreme heat stress+38 to +42 +35 to +41 strong heat stress+34 to +38 +29 to +35 moderate heat stress+30 to +34 +23 to +29 slight heat stress+26 to +30 +18 to +23 no thermal stress+22 to +26 +13 to +18 slight cold stress+18 to +22 +8 to +13 moderate cold stress+14 to +18 +4 to +8 strong cold stressbelow +14 below +4 extreme cold stress
I attached below an example of PET humid climate comparison with UTCI, for in-shade and out-shade conditions.As it can be seen UTCI shows the percent of time comfortable: two times higher than PET.
Thank you Pin, for the useful comment, on usage of "Analysis period" component.…
ll these 12500 points.
Group 1 would represent the point located at 0, 5, 10, 15, 20 etc.
Group 2 - 1, 6, 11, 16, 21 etc.
Group 3 - 2, 7, 12, 17, 22 etc.
Group 4 - 3, 8, 13, 18, 23 etc.
Group 5 - 4, 9, 14, 19, 24 etc.
I can create the pattern but the selection of points are all the points in row 0 and then all the points in row 5 and so on.
I would like the selection of points to start at the bottom left, and sequentially continue to the right and then continue on the 2nd row (left to right & bottom to top). i am hoping the pattern i am trying to achieve is more understood with the quick screen capture I uploaded.
the end goal is to be able to select all the points in the grid that are in each pattern.
Thanks in advance for any guidance with this. …

i mean, i want a slider that can do 3 sides, 4 sides, 5, 6, 7, 8, 9 and 10. for the grids because I dont want to use a fixed grid shape such as square grid (4 sides only).
e

8. True <-- this one

Any idea how I can solve this?
Thanks!…
en 3 of them, and one poolyline between two of them.
It would also be very nice if i could control it so that only the successive ones can be connected
so if {0:0:0} has 8 points and {0:0:1} has 8, as do {0:0:5} and {0:0:6} i would like to have this as two polylines, not one continoous that would in this case jump three branches (or curves that are shorter).
Does this make any sense?…

ndomly select a list of 16 points, a list of 22 points and a list of 4 points which would then represent the three separate sized squares. Can anyone help? Much appreciated for your time.…
