Abstract
Energy performance certificates (EPC) are obligatory for new and existing buildings in all European Union (EU) Member states, and provide not only the characteristics of individual buildings but are also useful for energy management and planning. However, despite the current widespread of EPC analyses in other European countries, the information of national EPC cadastre in Lithuania is hardly adapted in research studies. This paper presents an overview of the energy performance of Lithuanian residential building stock using data from the national EPC register. The results determine the current situation in Lithuanian residential buildings emphasizing CO2 emissions and their dependencies on different heating systems during latter 5 years. The findings of this research could be used as guidance for management of CO2 emissions in order to comply with the EU requirements by 2050. Moreover, the recommendations for the extended scope of national EPC content are also proposed.
