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.…
am however having a problem with something simple - limiting a set of values between a fixed set that I need help with please?
For example, I'd like to transform this list . . .
(2, 16, 4, 65, 12, 41, 7, 1, 22)
into this one . . .
(5, 16, 5, 25, 12, 25, 7, 5, 22)
i.e. selecting all numbers below 5 and changing them to 5 and selecting all numbers above 25 and changing them to 25.
I know it's possible with a simple If, Not, Then series but I'm rubbish at code!
Also, is there a simple way to apply dimensions to rhino objects from within GH?
Thanks for your help!
Cheers

The type of recipe appears to be related to the problem, because de error desolves when I connect the component to a different recipe.
A screenshot of the complete error message is in the attachment.

Also if you are fabricating something with Ivy please share some images if you can. I would love to see what people are able to achieve using it.
Best,

can not open them, he says: "file read failed".
Is it possible that it is because I work with the updated version of Pachyderm in September 2017? (and not the last one I saw you put in December 2017?).
If not, what can it be?
Thank you again,
Kind regards

d period (from 18th to 31th July 2017), for example the 25th July 2017, I have all hourly data of the previous week so I can define the ruuning mean temperature. In this case it is not required the full annual data stream of outdoor temperature. It's correct?
2) if I use the "monthly average" option, in the case of a shorter period than one month, the average monthly value can be replaced by the average calculated on the basis of the available data. It's correct?
