N2 - The overarching objective of this study is to develop the numerical model based on reaction-diffusion model that predict colony forming by taking into account the influence of nutriments, moisture, temperature and surface characteristics of building materials for various fungi. Toward this end, this paper provides two results. The first topic is the results of fundamental experiment which measure the growth responses of colony size on culture media under various environmental conditions. The second topic is concerning the mathematical models that reproduce the colony formation on the PDA medium and numerical simulation intended for the experimental conditions. As results by the execution of the sensitivity analysis, we did the fitting of the model coefficient by using the experiment data. The mathematical models proposes by this research received a strong influence to the nourishment concentration on the surface of construction materials, and were in reasonable agreement with the experimental data.
