The Portuguese housing park, especially in what concerns to older buildings, is very degraded due to the lack of maintenance over the years, resulting in the depopulation of many historical centres of the country. The specialists usually characterize the housing park in different construction times, being based on the regulation and the implementation of different trends and technological evolutions in construction. In Portugal, the 60's decade of the twentieth century stands out by the construction of a significant number of multifamily residential buildings with a resistant reticulated structure and without concerns from the point of view of thermal behaviour. In this work, the case study of a multifamily building of the construction period mentioned previously, located in the city of Covilhã, in central Portugal, is presented. The analysis of the case study is divided into two main stages: technical inspection of the building and identification of intervention proposals based on the analysis of detected constructive fragilities. In the first phase of the study a technical inspection sheet adapted to multifamily buildings was created and applied, accompanied by a survey of the residents, in order to know the occupancy conditions, the sensitivity and the expectations about intervention. In addition, a thermal analysis was carried out with the support of thermography, data analysis of temperature and relative humidity measurements performed at certain periods of time and thermal quality evaluation based on the calculation methodologies for the energy certification of fractions. After analysing all the elements registered in the first phase of the case study, it was possible to propose duly substantiated intervention measures with the main concern of creating better access, use and comfort conditions.
