Abstract: This paper tends to give a general overview regarding the situation of energy efficiency for public building in Albania. As first attempt, will be their classification based on energetic viewpoint. Classification is based in many factors like: destination, users, time of operations, thermal comfort, etc. Based on this analysis 6 type of public buildings are distinguished: hospitals, kindergarten, schools, universities, dormitories, institutions of central and local government. Also an analysis of their energy behaviors is made in order to highlight their weaknesses. Analysis put in evidence that due to the design and construction the existing building stock is not in compliance with the laws and their regulatory, regarding energy performance. Electricity represent the main primary energy source since this sector has a highest electricity dependence and consumption. Other identified primary energy sources are: diesel oil, pellet and natural gas, used mostly for heating during winter season or domestic hot water production. Most of buildings do not meet minimal thermal comfort standards and suffer from a poor thermal insulation, so most of energy is consumed for heating or cooling. Another problematics was building operation and management, which is poor or inexistent. Due to this heat loses from air infiltration represent 20÷40% of total heat loses in the building. At the end some conclusions and recommendation are given in order to improve energy efficiency and thermal comfort in public building.
