WUFI

Hello All,

I am looking for the properties of icynene insulation.

Density and conductivity are readily available, however the manufacturers do not have the liquid Transport Coefficients and Moisture Storage Functions.

I would appreciate if anyone can forward me any sources for materials.
If you ...

Dear Manfred,

Is this feature the same as the air change feature included in the WUFI 4.2 version.

I have tried using the feature however the results look like the air change is still coming from exterior conditions and weather data rather than using interior conditions.

It would be beneficial to ...

Thanks Manfred. Just wanted to know if there were any precedents for it.

I am a new member of the forum and would like to say hello to everyone here.

I am working on a building assembly that has some thermal bridges.

Is there an approximate way to simulate a thermal bridge in WUFI using heat sources and sinks?

Finally, what would be the best location to place the heat ...

The set points will depend on your design. That info usually comes from the HVAC engineer.
ASHRAE 160P gives a good methodology you can follow when doing your analysis.
For ASHRAE 160P document go to:

and download the PDF.

The following link is a narrative ...

Thanks Manfred. Appreciate the prompt response.


Yes, but the growth of mould does also depend on the suface type (Aga-Aga, organic, or mineral)
I understand that the material is a factor. But if the organic matter is available such as dust, dirt, etc., and the moisture level and temperature is ...

I would like to create weather data for Dallas/Fort Worth in Texas.
The climate is not available in the WUFI Pro package.

I am planning to use TMY file and convert it for use in WUFI. However, I understand that the Typical Meteorological Year that is used for energy simulation is not the best for ...

Can similar criteria be applied to concrete?
For example to keep the moisture content below the storage capacity at RH=80%? Also to keep surface RH<80% for extended periods to prevent mold growth?
The storage capacity of the materials in the library is in units of kg/cu.m. The result graphs also ...
