Solar energy has a great potential in Albania. The use of hybrid photovoltaic – thermal (PV/T) systems has shown an impressive progress in recent years. PV/T system can produce electricity and thermal energy simultaneously. In this paper, a 200 W PV/T system is introduced using water as cooling fluid, in order to regulate the temperature increase of the photovoltaic panels. The heat is collected via working fluid in a water tank. This study analyses the energy generation of this experimental setup, and aims to provide some accurate information in future developments and implementation of this technology in Albania. Coupling of PV/T system with heat pumps in buildings to meet the energy requirements could be of great interest for Albania’s energy consumers

During the last two decades the Heating Ventilation Air Condition (HVAC) systems have been used to enable heating, cooling and ventilation of buildings with the primary aim of meeting the requirements of thermal comfort and indoor air quality. In this research work, energy consumption in buildings has been analysed by using Hourly Analysis Program (HAP) software. The object of our research work was focused in the Polytechnic University of Tirana. Mathematical models of thermal calculations have been based on the international standard ISO 13790: 2008 on energy use and thermal performance of buildings.
