Development and application of a methodological model that allows evaluate and compare the behaviour of external walls exposed to moisture phenomenons

The thesis has the objective of design a methodological model for evaluate and compare the behaviour of external walls exposed to moisture phenomena. The comparison is related to different variables us for example: thermal conductivity, thermal transmitance, moisture content in the element along the time, P.O. Fanger theory of comfort, risk grouwth of mould among the others parameters. The model is developed in function of two softwares that permit sensibilyze the performance of building elements in relation of the presence of different quantities of moisture inside of them along the year. In this case, the model is probe with the use of TRNSYS 15 and WUFI 3.2 Pro softwares. The results show that there are many differences in the analysis of the different parameters in the cases with the materials in dry and wet state. Also, is possible to realize that the improve of any constructive solutions they are amortized in periods of time that no exceed more than three years in relation to the save of energy for the improvement in the themal conductivity of the materials.(FSA 3)--UCL, 200
