| Sumario: | To assess the thermal transmittance of facades is one of the most important steps in energy audit work. For this, there is a wide variety of experimental methods. One of the most widely used methods is the thermometric method. However, there is a knowledge gap in relation to the data analysis approach. For this reason, in this study the feasibility of using different approaches to the method was analyzed. To do this, 20 façades were analyzed and 9 different formulations were proposed using approximations for the total heat transfer coefficient of the scientific literature. Likewise, two approaches to data analysis were evaluated (arithmetic mean of the instantaneous measurements, and the sum of the numerator and the denominator), as well as the data filtering necessary to apply. The results allowed determining the most suitable analysis configuration to apply the method. © 2021. CSIC. All Rights Reserved. |
