Abstract

The stock of Albania buildings dating between 1955 and 1985 during the communist period is a very powerful and important footprint not only in the city of Tirana, Albania, but all over the country. This category of buildings is positioned mostly in the center of the city, within the inner historical ring of the city of Tirana. They are designed considering the mottos: standardization and typification representing the standards of the time. In the city of Tirana almost in every neighborhood are located underground anti-bomb tunnels. Since the majority of them nowadays are out of functions, they are destroyed. Despite this fact, the specific neighborhood taken into consideration includes in the inner block area these shelters. The socialist regime and professionals of the time do not consider the orientation of the building toward sun in order to benefit from the solar radiation. Furthermore, the buildings are placed randomly in the urban structure of the city. Regardless to that fact the analysis of the WWR and WFR showed relatively good results compared to the international case studies. Building thermography and U-value measurements of the building showed poor results compared to international and national standards. Taking into consideration this fact, immediate improvements are needed in order to include the buildings within the comfort zone, enhancing its thermal potential category. The analysis of the existing building structures and their construction materials is crucial in order to have a better understanding of the thermal potential of them. The structures are measured and designed according to their actual physical conditions. The buildings require an immediate energetic requalification, avoiding at the maximum the thermal bridges as part of them.
