Thermal performance of different masonry wall composition. Case study: Polis University, Tirana, Albania

Abstract

Albania is part of the emerging economies of the Western Balkan region. Polis University is one of the pioneering institutions in the field of architecture, built environment, and city sciences that represents innovative methodologies and concepts for educational and scientific purposes. Nowadays, many constructions in Albania involve a wide range of different materials. The building envelope is one of the main elements that provide protection from the outside environment but also the required thermal comfort for the inhabitants. The necessary balance must be archived between energy efficiency and the durability of buildings. This paper will focus on the thermal performance and materials composition of two different types of masonry walls, a constituent part of Polis University’s main building. The study will be based on an experiment using specific instruments to diagnose these typologies of wall composition. The results are further analyzed and compared. Specific instruments such as the thermal camera (Testo 882), U-value (Testo 435-2), and “Silverline Digital Moisture Meter” (from POLIS Energy lab) are engaged. The collected data are further interpreted through graphs, tables, and diagrams for both cases. It is observed that ventilated facades perform much better than standard facades, therefore their usage is strongly recommended.
