A considerable part of Southern European countries building stock was constructed before the implementation of national thermal regulations, and as such, it is currently exposed to challenges such as energy poverty and climate change. Portuguese public social housing presents a significant variety of construction systems and applied typologies. Among them, the “Novobra NK1”, a precast concrete construction system that exploits some innovative features in envelope components, has been used in several projects. Considering the importance of retrofitting to improve and adapt the thermal behaviors of buildings to face the aforementioned challenges, this article aims to provide an understanding of the behavior of a NK1 thermal envelope of a dwelling located in Covilhã, Portugal, and the impact of some constructive envelope retrofit measures applied. Results show that existing opaque envelope elements and glazed areas present characteristics that are no longer able to provide proper responses to contemporary building constructive requirements. External insulation was identified as a key retrofit measure, window replacement also being an advised solution for rigorous heating seasons. Improvements from the internal side of windows, such as roller shades, may provide few benefits during cooling seasons, and applying solar films is not advised without a proper thermal repercussion analysis.

An important part of the Portuguese social housing building stock is unappropriated regarding the actual regulation and resident’s comfort requirements, which are expected to increase due to the impact of climate change. Beira Interior region in Portugal is one of the fewest Portuguese zones that presents both winter and summer most severe scenarios in many places. Future climate scenario projections for this region indicate more aggressive summer seasons, with the occurrence of heat waves becoming more significant, while winter seasons are expected to maintain a rigorous profile. The present article, which reflects the work still in progress, presents the development of a proper methodology for social housing retrofit in Beira Interior region for present and projected climate scenarios under Portuguese realistic cooling/heating habits of occupants. It focuses on monitoring internal temperatures in order to understand actual dwellings performance considering occupant behaviour, along with the construction of a dynamical multi-zone model for dynamical thermal simulations. Comparing the results with appropriate thermal comfort standards, proper retrofit measures will be identified and tested. Therefore, it is aimed the accomplishment of constructive retrofit guidelines, which are expected to be valuable tools for stakeholders interested in the retrofit of the Portuguese social housing stock.
