Abstract (EN):
The thermal performance evaluation of buildings relies on the European Directives on Energy Performance of
Buildings, providing the framework on which all member states should improve their buildings ‘energy
efficiency’. However, it is established in several literature, there is an important gap between normative
calculations and measured consumptions. In Portugal, this is explained by a mild climate and a high fuel poverty
phenomena. Thus, for low heating countries, the thermal performance should rely on the discomfort
minimization. It was performed the comfort assessment of dwellings located in the typical building with massive
walls and wooden pavements and roof, with or without insulation on walls, for different orientations. The
numerical model was validated with experimental data. The comfort was assessed considering the adaptive
approach of the European Norm 15 251, for free running conditions, or with low heating profiles. Results show
the insulation introduction has a very small impact on discomfort minimization, for low heating profiles in mild
climates, what shall be considered, bearing in mind it presents many times technical difficulties in historical
buildings.
