Estimating Values for the Moisture Sources and Buffering Capacities from Indoor Climate Measurements

The objective of the paper is to investigate the potentials of estimating values for the total human induced moisture source and the total buffering capacity of the interior objects with the use of relatively simple measurements and the use of HAM models. The paper presents the related modeling approaches, the implementation in the MatLab/SimuLink environment, a verification study and evaluation of the models using indoor climate measurements of a Dutch museum. It is concluded that the modeling approach may be useful for estimating the human induced heat & moisture sources. The case study was not usable for estimating the buffering capacity of the interior objects due to the minor dependency on the amount of moisture storage material. More case studies are required to evaluate our approach for the determination of such moisture capacities. However, our approach has the side effect that it might be usable to indicate the effect of wet clothing. Our study showed that the moisture source of wet clothing per person could be of the same order as the breath induced moisture source. Further research is needed if we want to quantify the effect of wet clothing more accurately.
