[BLDG-SIM] dew point and moisture control in walls

[Alpana Jain]

Thomas, Esiyok, Vaibhav,

 

Thanks so much for all the information. I think MOIST and WUFI, both are
going to be helpful for what I need.

 

Regards
Alpana

Alpana,

 

You might try MOIST, a free software program you can use to calculate
temperature profiles and dew point in wall assemblies. Check out this
URL for details:

 

www.bfrl.nist.gov/863/moist.html
<http://www.bfrl.nist.gov/863/moist.html> .  

 

MOIST is a one-dimensional, steady-state analysis, and there are other
considerations that have to be taken into account when analyzing dew
point. Among them are; seasonal and diurnal variation in wall
temperature and RH; the edge effects of studs, windows and framing; the
dynamics of wetting and drying in a cavity; and how a vapor barrier is
used.

Hi,

 

I was wondering if there is some way of modeling the effect and extent
of the vapor pressure, dew point and condensation within walls?
