WUFI

Hi All,

I am trying to model and reproduce the roof systems as simulated in an article titled "Compact Asphalt Shingle Roof Systems: Should They be Vented?" by Nelson and der Ananian.

The authors have discussed the model construction but there are a few things which are not clear to me.

1) The ...

I want to model a leak in the roof (conventional roof with asphalt shingles, underlayment and OSB sheathing) to simulate wind driven rain.
For this purpose, I am using an external Moisture Source with multiple leak events (1 hr duration) every alternate day for 3 months.
For experimental testing, we ...

I am doing the analysis of a roof model in WUFI 1D.

In the results, under "Quick Graph", we can see the "Water Content in Layer". The primary Y-axis shows the water content in kg/m3 while the secondary axis shows water content in M-%.

I just wanted to confirm if M-% on the secondary Y axis is the ...

ccSPF has already been installed in a test house. The test house is an occupied residential 1 story house in Gainesville, FL with a vented attic.
We are monitoring the temperature and relative humidity both in exterior and interior of the house and attic.
Based on how good we are able to model and ...

Hi

I am trying to model a vented attic of the roof in Florida. The attic has been retrofitted with ccSPF for strength and insulation. I want to model the vented condition in the attic.
The exterior is the roof surface which is exposed to atmosphere and interior surface is in the attic which is ...

I am simulating a vented residential attic with closed cell foam insulation sprayed on the OSB sheathing. How and where should I simulate the attic ventilation?
I have used an Air Layer (50 mm) and applied a constant ACH of 5 to it. Is this the right way to do this?
Where should this Air Layer be ...

What should I use for modeling Asphalt Shingles? Is the Asphalt impregnated paper equivalent to Shingles?

How can I get the Temp/RH values at monitored locations in my model in a Tabular format?
Is there a way to export it from the Animation file or results file?
I exported the data in ASCII format but is there any way in WUFI to convert it back in the number format?

I wanted to know how to model asphalt shingles and felt underlayment for a roof. Is it included in the Material Database (Asphalt impregnated paper/Building paper/Bituminous Paper).

I wanted to model Leakage in the Roof due to Rainfall. Can anyone please help me how to do this.

Will I have to include a new material file for that?
