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

The objective of the present study is to experimentally investigate the thermal comfort inside a car cabin. During the experimental campaign the occupants filled out questionnaires on the thermal sensation vote. The questionnaire contained questions about the local and global state of comfort and were performed according to ISO 14505-3 / 2006 and ISO 10551 / 2001. Each experimental session lasted 30 minutes and each occupant completed four questionnaires as follows: a questionnaire at the entrance in the car cabin, and afterwards one questionnaire every 10 minutes.
