Experimental Energy Performance Assessment of a Simplified Building: Study of Robustness of Different Analysis Approaches under Different Test Conditions.

This paper reports the study of different aspects of data based modelling, focusing on physical issues and considering a simplified case study. Different analysis approaches have been applied to several data series recorded in different test conditions. The results have been compared. The effect of solar radiation, and the relevance of non- constant surface effects have been evaluated through an exploratory mono-dimensional analysis. Afterwards tri- dimensional analysis has been applied, to estimate the overall UA and gA value of the simplified building. The robustness of the results is studied comparing results from data set recorded under different test conditions. [ABSTRACT FROM AUTHOR]
