Climate Summary #104

Closed giobetti closed 2 years ago

giobetti commented 3 years ago

Hi Federico,

I am trying to put togrther a couple of more coherent thoughts than I have managed so far on the topic.

I believe a climate summary can be helpful and should be entirely contained in he tab with the same name.

It should contain the following:

Köppen–Geiger climate zone: Cfb. Marine west coast, warm summer. Average Yearly Temperature: XX degC (this can be useful to quicly understand how much yearly swing there is -i.e. difference between average and max and min or just get a sense of how "hot" or "cold" or as proxy for ground temperatures)

Coldest Week: x/x to y/y Typical Winter Week: x/x to y/y Coldest Yearly Temperature (01%): YY degC

Hottest Week: x/x to y/y Typical Summer Week: x/x to y/y Hottest Yearly Temperature (99%): YY degC

Yearly Cumulative Global Horizontal Solar Radiation: ZZZZZ Kwh/m2 of which diffuse: AA% (this value can be very different in a place like jerusalem and KL even if both have crazy high numbers of totoal solar radiation)

What do yu think?

Best,

G

I agree with you, I have added the following: image

To be honest I am not sure about the week info since they do not make much sense to me. Don't week always move around each year? What is a week, sometimes they consider it starting on Sunday or Monday? Why would this info be so relevant, what does it change if the coldest week is the first or second of Feb? How the user will benefit from that. Maybe we can report the coldest month then, or when the 99% and 1% temperatures were recorded.

Coldest Week: x/x to y/y Typical Winter Week: x/x to y/y Hottest Week: x/x to y/y Typical Summer Week: x/x to y/y

Climate.onebuilding.org classifies the seasons like this which is not very intuitive image

Some extra summary stats are summarized here: image

Or in this file

Hi Federico,

The idea with the week info is those are the typical or extreme weeks in the epw weather file. So you just look at those data to see what are the conditions. Sometimes you might want to run a thermal simulation just for one of those week to check peak or typical load. That’s why it is helpful information

FedericoTartarini commented 3 years ago

okay, that then makes sense, the only problem is that this info it is not included in the OneClimate files, it is only included in another supplementary file that is within the same Zip folder. Shall we calculate the hottest week by simply assuming that the year starts from a Monday and then calculate the week with the lowest and highest average tmp?

giobetti commented 3 years ago

I am not actually sure weeks need to start on Mondays... I always thought of it as a 7 day period, but I am not sure that's correct.

I got in contact with the One.Building guys that where interested and supportive of the project. I might need to gett back to them.

Regarding this summary: image

Would it be possible to express the diffuse horizontal radiation as a percentage of the global horizontal? I think understanding the split is more important than the absolute number

FedericoTartarini commented 3 years ago

Sure I can convert it into a percentage.
