WUFI

Many thanks

Dear Team, I am wondering what critical limit IBP use for RH at the IWI/masonry interface for a woodfibre based insulation like Steico, Pavatex, Gutex, Homotherm etc. The (presumed) absence of oxygen should mean that the limit is higher than 80%RH, but do you have a safe limit to work to when assess...

I think that is the problem with using try files, i'm looking at driving rain and not getting the results i was expecting.

Good luck

Dan

Could anyone please suggest which type of climate file to use for extreme events such as driving rain, .WET, .DAT, .WAC, .IWC? I have been using .TRY files.

Merry Christmas

I have quite a few TRY files for the UK. Meteonorm software will create them for you anywhere in the world or you can buy individual files from them. http://www.meteonorm.com/pages/en/meteonorm.php They come as a .TRY file (test reference year) which does not contain extreme conditions, good for som...

Hi Moritz, See AWK below. $ denotes which column of the ascii file to look at, in the example below I am looking for below zero events in column 3 coinciding with a water content above 208 in column 4. Change accordingly. If you need any help with it let me know Best Dan my AWK '208': { gsub(/E\+000...

Hi Joseph,

I have had the same problem with adding UK bricks, WUFI needs lots of values that are often not even tested for.

Have you spoken to Prof Tom Woolley? He is based in Ireland and is a hemp lime fanatic!

Hi Joseph,

excellent work!!!

I look forward to it. If you save a hemp/lime simulation without the film then it can be emailed easily, you might have to save it before running it, look at the file sizes.

I am also trying to simulate some UK bricks, any ideas??

Regards

Dan

Does anyone have any material values for UK bricks, I have tried to model a Stewartby Fletton but am not sure that I have all the data for it to be accurate.

I have written an AWK programme that scans my ascii outputs for specific events, in my case freeze/thaw damage. It can be easily rewritten to look for different events.

I am happy to share this with anyone that needs it.

Hi, I am having some trouble with an awk programme that i have co-written that scans my WUFI ascii output file. This is partly a problem with me not writing the perfect awk programm, partly because i'm doing it in terminal/darwin on my mac and also because the WUFI ascii outputs are so 'dirty' (sorr...

Hi The main person to contact at CAT regarding hemp lime is Ranyl Rhydwen, he wrote his PhD thesis on it and also has an interest in WUFI. Many of the students are researching it for their masters’ theses and he will be able to point you in the right direction. Mention my name, he knows me. : ranyl....

Hi Manfed, thanks for your reply.

Hi,

The .try dwd climate file I'm using has the altitude set to 0 masl. is this going to give unrealistic wind driven rain results?

Thanks

HI, I am studying on a masters course at the Centre for Alternative Technology in Wales UK, where many students are researching hemp/lime. If you would like i can put you in touch with some students/tutors that have been trying to define the values. Also Peter Walker at Bath University in England ha...
