[Bldg-sim] Fwd: Re: Cost of climate file

Mon Nov 14 12:47:07 PST 2016

It seems like this topic comes up on here nearly every week.

There are many sources of weather/climate data.  Some free, some not.  Some are very questionable in their accuracy, others are not.

As a very wise man once said, “Just because you can get something for free on the internet doesn’t mean it’s worth it”.

Can we create a mailing list rule that any time this topic comes up the server just automatically replies with a series of links about where you can get weather data?  I’d be happy to work with everyone on this list to compile the links and put together the requisite disclaimers about knowing where the data comes from and ensuring you’ve analysed it to ensure its validity prior to using it.

In other words, haven’t we reached the point where weather/climate data ought to be a “sticky” at the top of the mailing list?

As far as sources go, IES have compiled (an incomplete) listing of both free and for-purchase sources of weather data.  For those interested, here it is: http://www.iesve.com/support/weatherfiles

Kind regards,

Nathan

Hi Nick,

Weather analytics do still provide weather files for the industry and Sefaira uses their epw files for our EnergyPlus analysis where other information is not available.

That said I echo your sentiments that Joe is great at responding to questions on this forum and it's greatly appreciated by the industry.

Best,

Andrew

As someone with zero financial interests in any of the mentioned weather service companies, and as a consumer who has used these services (and also practiced a fair bit of composing/vetting my own weather files from raw data):

I think it speaks volumes and is worth highlighting that one of the owners of these service companies seems to contribute to/answer 99% of the questions posed about weather data sources and how to manipulate them, both this in forum and elsewhere.

Thanks Joe, for your pro bono services to our community, as well as the paid ones!

I’m also comfortable recommending WBT’s services to new and experienced simulators alike.

I should also insert Weather Analytics (a service I used to frequently recommend) shifted into new management/markets in the last year or so, and I don’t believe they service the “building energy simulation sector” any more in the way they used to.  If anyone has experience to the contrary and has been able to do business with them in recent months I’d be keen to hear about it!

There are two IWEC2 weather file for Zurich (CHE_ZUERICH-METEOSCHWEI_066600_IW2 and CHE_ZURICH-KLOTEN_066700_IW2).

IWEC2 (International Weather for Energy Calculations) weather files were developed in a 4-year ASHRAE project utilizing actual weather reports from thousands of stations

throughout the world going back 25 years, and covers locations outside of the United States and Canada. The entire set of 3,012 IWEC2 weather files is

available on a DVD from ASHRAE (see link here<https://www.ashrae.org/resources--publications/bookstore/iwec2> )

Individual IWEC2 weather files are available online from White BoxTechnologies, Inc. in various formats (BINM for DOE-2, EPW for EnergyPlus,

etc.), as well as country sets or even the entire IWEC2 collection. For a complete list of all IWEC2 stations, see here<http://www.whiteboxtechnologies.com/IWEC2_locations.txt>. For a map view of the IWEC2 stations in Google Maps,

see here<http://weather.whiteboxtechnologies.com/map-IWEC2>

Hi,
I am looking for an EPW climate file for Zurich Switzerland. I also find that every now and then we have the need for simulation climate files that aren’t readily available in EPW format

I know there have been a few discussions on this site about services/software programs that do this for you.

What does it cost? And what is the process for creating one of these files?

Thanks in advance
