Building performance simulation of ‘t Centrum project in Westerlo, Belgium

This dataset represents a building energy model for carbon-neutral office buildings located in Belgium. EnergyPlus has been used to model energy use such as heating, cooling, ventilation, lighting, and process loads in buildings. Antwerp weather file was selected as the closest and data-rich airport weather file to Westerlo. Antwerp falls under the Köppen-Geiger classification of temperate oceanic climate with no dry season and warm summer. Offices are typically heating- and cooling-dominated with an average of 2300 Heating Degree Days (HDD) and 45 Cooling Degree Days (2016–2020, base temperature 15 C HDD and 24 C CDD). Antwerp meteorological weather data for 2016–2019 were requested from the Belgian Royal Meteorological Institute. The characterization of the building properties and occupant profiles was based on the input used for the Belgian EPB dynamic simulation model that has been used for energy simulation in this project. The energy performance assumptions comply with the Flemish energy performance regulations for 2019, including insulation, installation, ventilation, and overheating requirements. The building is an all-electric zero energy building with three glazed facades. The ground floor is glazed with vacuum glass, and the upper floors are triple glazed. The building relies on a mechanical ventilation system with heat recovery. Six boreholes are coupled to the heat pump to meet the heating and cooling demand.The heating and cooling system is coupled to a geothermal water loop with the air heat pump. VESTAD, the building services firm, provided their EPB report for the building envelope and installations, including the photovoltaic system.本数据集为面向比利时碳中和办公楼的建筑能耗模型。本研究采用EnergyPlus软件对建筑采暖、制冷、通风、照明及设备负荷等各类能耗进行建模。研究选取安特卫普（Antwerp）机场气象文件作为与韦斯特洛（Westerlo）最为匹配且数据详实的气象数据源。安特卫普属于柯本-盖格（Köppen-Geiger）气候分类体系下的温带海洋性气候，无明显旱季且夏季温暖。该类办公楼通常以采暖与制冷负荷为主要能耗组成，2016-2020年的平均采暖度日数（Heating Degree Days, HDD）为2300，制冷度日数（Cooling Degree Days, CDD）为45（其中采暖度日数基准温度为15℃，制冷度日数基准温度为24℃）。2016-2019年安特卫普气象数据来源于比利时皇家气象研究所。建筑属性与人员行为特征的参数设定参考了比利时EPB动态模拟模型的输入规范，该模型亦为本项目能耗模拟所采用的工具。本项目的能耗性能设定符合2019年弗拉芒大区建筑能耗性能法规要求，涵盖保温构造、机电安装、通风系统及过热防控等相关条款。该建筑为全电气化零能耗建筑，共设置三面玻璃幕墙；首层采用真空玻璃幕墙，上层楼层则采用三层中空玻璃幕墙。建筑配备带热回收功能的机械通风系统，共布设6个钻孔换热井与热泵系统相连，以满足建筑采暖与制冷需求。本项目的采暖制冷系统与搭载空气源热泵的地热水循环回路实现耦合连接。建筑服务企业VESTAD提供了该建筑围护结构与机电系统（含光伏发电系统）的EPB报告。
