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.

摘要

能源绩效证书（EPC）对于所有欧盟（EU）成员国的新建筑物和现有建筑物都是必需的，并且不仅提供单个建筑物的特征，而且对能源管理和规划也很有用。但是，尽管当前EPC分析在其他欧洲国家中非常普遍，但立陶宛国家EPC地籍的信息却很少用于研究。本文使用国家EPC登记簿中的数据，对立陶宛住宅建筑的能源性能进行了概述。结果确定了立陶宛民用住宅的现状，强调了未来5年的CO2排放及其对不同供暖系统的依赖性。
