Description	Energy consumption presents increasing trends during the last decades, presenting a great challenge. The building sector contributes to a high proportion of the energy consumed and therefore efforts should be focused to improve energy efﬁciency of buildings. For such purpose, the use of phase-change materials in building envelopes has been extensively studied and its beneﬁts were demonstrated. However, there is a lack of simple evaluation tools to assess these beneﬁts. In this article, a previously proposed methodology based on four indicators, which were tested through simulation only are experimentally validated using brick, concrete and timber constructions, incorporating phase change material (PCM). Results show that the methodology is successful for buildings with heat gains and having low thermal inertia or insulation. However, for highly insulated buildings with signiﬁcant inertia and low heat gains, the method fails to assess the potential beneﬁts of the PCM. Moreover, the ITD indicator is found to be the most accurate in assessing PCM beneﬁts compared to other parameters studied. In this article, the ITD indicator will be modiﬁed to consider upper and lower comfort temperature levels rather than single set temperature.
