Análise paramétrica das propriedades higrotérmicas da taipa de pilão para uso na simulação termoenergética

Abstract

Traditional structures such as rammed earth constitute an alternative that incorporates local principles and materials to promote both the sustainability of the building and the comfort of users. In this context, the objective of this work was to parameterize the hygrothermal properties of rammed earth through different computer simulation processes for application in the evaluation of thermoenergetic performance of earth constructions. The methodology consisted of modeling and computer simulation of a building with mud walls, using the software EnergyPlus (version 9.4) and Jeplus (version 2.1.0). Two thermoenergetic models were considered: CTF (conduction transfer function) and EMPD (effective moisture penetration depth). Furthermore, the variables studied were the thickness of the walls (12, 20 and 30 cm), the hygrothermal properties of the rammed earth based on a bibliographical review and the routine use and occupation of the building. The results indicated that there was no significant difference between the CTF and EMPD methods for evaluating the thermoenergetic performance and thermal comfort of users in the rammed earth environment. It was observed that both the routine of use and occupation and the thickness of the rammed earth walls have a significant influence on the building's energy consumption. As a final product, a confidence interval was defined for the values of the hygrothermal properties of the rammed earth, in addition to presenting recommendations for the application of the results as design guidelines. This contributes to advances in the standardization of the specificities and replicability of earthen construction systems in civil construction.
