Procedures in the construction of a test reference year for Porto-Portugal and implications for hygrothermal simulation

The results were statistically compared and they showed the reference years presented differences, although only three months are actually different. The outputs of the hygrothermal simulations are similar in some periods and different in the periods of time close to the months that are different in the reference years. Although these dissimilarities are highlighted by statistical differences they are not relevant enough to result in a significant difference in the durability of the materials.
