This data article includes a dataset developed between 2020 and 2022 to characterize and analyze the state of energy efficiency of nearly zero energy buildings in ten Eastern European countries. The data article refers to the paper' Overview and future challenges of nearly zero-energy building (nZEB) design in Eastern Europe' (Attia and Kosinski et al., 2022). The data provides an overview of the status of building energy use, energy savings, and regulations for the newly constructed building stock, including Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, and Slovakia. The importance of the dataset lies in its unique approach of data collection that provides detailed information on electricity, gas, oil, coal, and wood used in the investigated countries between 2015 and 2020. The methodology involves compiling and fusing data from national registries and depositories written in ten different national languages. Thus, the data is not available in Eurostat or any EU platform. The methodology followed to produce the data is mainly a literature review of restricted national publications and an extensive questionnaire with 14 national experts involved with the nZEB implementation plans and policies. The data include several parameters, including building energy efficiency thresholds expressed in the form of primary energy use intensity; primary energy conversion factors; renewable energy shares; building envelope performance requirements; mechanical ventilation performance requirements; thermal comfort requirements; construction rates of residential buildings; and heat pumps market penetration expressed as heat pump units per 100 households. The data paper is valuable for scientists to conduct future research to implement energy efficiency measures and renewables towards energy-neutral buildings.
本数据文章包含一个2020年至2022年间开发的数据集，用于描述和分析十个东欧国家近零能耗建筑的能源效率状况。该数据文章参考了论文《东欧近零能耗建筑（nZEB）设计的概述与未来挑战》（阿提亚和科辛斯基等人，2022年）。该数据提供了新建建筑存量的建筑能源使用、节能和法规状况的概述，涉及保加利亚、克罗地亚、捷克共和国、爱沙尼亚、匈牙利、拉脱维亚、立陶宛、波兰、罗马尼亚和斯洛伐克。该数据集的重要性在于其独特的数据收集方法，提供了2015年至2020年间被调查国家电力、天然气、石油、煤炭和木材使用的详细信息。该方法包括汇编和融合用十种不同国家语言编写的国家登记册和存放处的数据。因此该数据在欧盟统计局或任何欧盟平台上均不可用。生成该数据所采用的方法主要是对受限的国家出版物进行文献综述，以及对14位参与近零能耗建筑实施计划和政策的国家专家进行广泛问卷调查。该数据包括几个参数，包括以一次能源使用强度形式表示的建筑能源效率阈值；一次能源转换系数；可再生能源份额；建筑围护结构性能要求；机械通风性能要求；热舒适要求；住宅建筑建设率；以及以每100户家庭的热泵机组数量表示的热泵市场渗透率。该数据论文对于科学家开展未来研究以实施能源效率措施和向能源中性建筑推广可再生能源具有重要价值。
