| Abstract: |
| When many of the current moisture control design guidelines for buildings were developed 50 years ago, they were consistent with analytical approaches and test methods. This consistency deteriorated when the importance of air convection was recognized. Although considerable research on moisture problems in buildings is available, there is no g~neral.., -con-sensuqs aimed at prevention. Sophisticated analytical moisture models have been developed,-but they are not eiisily available or are too complex to use as analytical or,desi.gn iool~.-C-u-rrent

Practical analytical tools need to be developed and test methods need to be expanded or developed to yield data appropriate for ' these models. Finally, more detailed information about airflow patterns in building com-ponents needs to be obtained.
