WUFI

Never mind, my bad, I forgot to make inch-pounds my default when I upgraded to 6.6

I've noticed that the old perm/in line item has disappeared in WUFI 6.6 and now has "water vapor diffusion resistance factor" in its place - is there a calculation that we can use to convert a manufacturer's perm ratings to this new resistance factor? I read the help article on this and do...

Sorry for the second post on this but haven't received a response to my first post. My company is providing me a new laptop so I need to understand how to move my user created database info from the old computer to the new - in addition, they will be upgrading me from Pro 6.1 to whatever the newest ...

I have the same issue, I'm moving 6.1 to a new computer, have both user defined materials and example cases. Will also be updating to latest version of Pro. thanks!

I will use the pure gypsum one and then switch to the one with organic matter to see how sensitive the construction is, if that makes sense.

Thanks Thomas. In addition, when I think about this more clearly, for the condition I have, there will be a waterproofing behind the tiles that is virtually impermeable also, so the tile and its joints are really not a factor in my mind.

I've been trying to track down information on the perm ratings for ceramic and porcelain tiles, anyone have a general range or any information at all? I'm trying to run a wall that in certain rooms has a shower against the exterior wall.

Manfred, thanks much, I appreciate being able to bounce these situations off you guys!

Manfred, I only used the term "brightness" because you did. You are correct the balances are thrown off on the south and west elevations, but not on the North and South - I am just floored that a .01 difference in absorptivity can create results that are so varied. If I select red brick ab...

So, If I select two different materials with two nearly identical "brightness" numbers, I should expect to get two nearly identical results - which did not happen in my case. This makes me wonder if something is incorrect with the red brick selection within the program itself. I say this b...

I'm seeing some odd results when selecting red brick for Short wave radiation absorptivity. I can select another color/product with similar numbers (red tiles for instance) that differs by only .01 in absorptivity, yet will produce a completely different result. This leads me to believe that the sho...

Is there a way I can model short term changes in Indoor climate/HVAC setting in WUFI? First example: I have a project where there is a workout room in the facility, for 2 hours a day they host a "hot" yoga class which involves temps up to 105 degrees Fahrenheit and 60% RH. Second example w...

Many of the product/material selections within the WUFI mold index tool are named for, what I assume, is the European market - for instance, what does the product "Pure gypsum or lime render" refer to? - what is the equivalent product in the USA? Would a gyp board product that has been tre...

I continue to have issues with the new air layers in my calculations where use of ATSC does not resolve, adjusting the steps & stage does not seem to work, adjusting the grids does not work, etc. Several times I have had to revert back to the old air layers to get anything that resembles calcula...

Well you can send an invoice, but whether or not I pay it is another matter! As always, thanks!
