Description

A detailed, three-dimensional finite element model called Moisture Absorption and Desorption Analysis Method (MADAM) has been developed at the Florida Solar Energy Center (FSEC) to evaluate the moisture absorption and desorption rates of building envelopes and internal furnishings. The model has been validated against measured laboratory and field data.

Moisture absorption and desorption correlations obtained through MADAM are then incorporated as a subprogram of Thermal Analysis Research Program (TARP). Mechanical system performance and building zone conditions are then evaluated on an hourly basis. MADAM/TARP analysis of residential. cooling loads in humid climates shows that moisture absorption and desorption can have a significant effect on air-conditioning loads and on indoor relative humidities. These effects are more pronounced when energy conservation strategies such as ventilation are used.
