MATCH
Moisture and Temperature Calculations for
Constructions of Hygroscopic Materials
MATCH (Moisture and Temperature Calculations for Constructions of Hygroscopic Materials)
is a computer program developed by Carsten Rode Pedersen in his study for the Danish Ph.D.
degree "Licentiatus Technices" at the Thermal Insulation Laboratory at the Technical University
of Denmark. His study included a six-month visit to ORNL in 1989. The theory used by MOIST
for the combined heat and moisture transport needed for calculations of the hygrothermal
behavior of composite building construction takes advantage of the similarities between the
governing equations for transient transfer of heat, vapor and liquid moisture.
MATCH is a one-dimensional model that accounts for moisture transport by diffusion and liquid
suction. The moisture retention properties have also been accounted for. The program runs on a
PC. The user interface is made easily accessible by supplying a small preprocessor and by
presenting results graphically as the calculations proceed. The intention with MATCH is that it
and similar models may one day be regular items in the toolbox of the building designer.
