Viewing data for USA climate files

Is there a way to export climate data for USA climate files? Specifically, I'm interested to know more about the hourly rain data for a certain city.

moisture source units

When inputting a moisture source as a fraction of driving rain, for 1%, do you input "1" or "0.01". I'm a bit confused what the units are b/c it's a fraction of driving rain, which would be 0.01, but the text box reads "Fraction [%]," which leads me to believe I should ...

ACH

I am modeling a wall with a rainscreen cladding system. I would like to simulate the vented cavity with the Air/Moisture Source. I can make the file with the air changes per hour, but I'm not sure what the appropriate ACH would be. Has there been any research done on this, and what do you feel is ap...

Concrete Block

What is the proper way to model CMU? Should I model the face shells and cells? Or should I use the "concrete brick" material for the 8 inch width of the unit. In other words, does the "concrete brick" material data account for the cells too?

Mon. Pos. Isopleths Quick Graph

When I go to the isopleths quick graph, the LIM B I and LIM B II limiting isopleths are only shown at the interior surface. Why don't I see them at all monitor positions? Thanks in advance!

ACH for a ventilated cavity

I'm modeling a wall system with a terra cotta rainscreen and would like to model the cavity behind the rainscreen with an Air Change Source. What is the appropriate way to approximate a ventilated cavity? (i.e.- accurate values for ACH) Also, does WUFI read excel files for the air change source?

temp/dew point quick graph

The temperature/dew point quick graph is new to WUFI 4.0. How do I interpret this data? When the temperature line and dew point temperature line overlap, there is a potential for condensation? If this is the case, it seems that in every model I run, to the exterior side of the vapor barrier, there i...
