HAMSTAD project

HAMSTAD PROJECT - Heat, Air and Moisture STAndards Development


HAMSTAD project (2000-2002) was an EU fininced project whose aim was to propose a better HAM-modeling methodology than the traditional Glaser method. The project consisted of two parts: Work package 1 (WP1), which focused on standards and methodologies for determination of moisture transfer coefficients and moisture properties of building materials, and Work package 2 (WP2), which dealt with HAM modeling methodologies and assessment methods for the development and evaluation of one-dimensional transient softwares for hygrothermal simulations. Reports of WP2 can be downloaded here:
