European energy policies introduced nearly zero energy building (NZEB) design to stimulate the energy transition in buildings, and EU programmes promote the evolution towards positive energy buildings (PEB). Most studies into NZEBs are based on simulations, and not on real monitoring data. This paper presents the real performance data of the Zero building, an NZEB office building with Leed Gold and Breeam Excellent environmental design certifications located in a neighbourhood that shares a zero-emission district heating–cooling facility relying only on 100% renewable energy sources. The current performance of the building and its neighbourhood is assessed to identify the existing gap to reach the goals of positive energy buildings (PEB). A study showed that it achieved a degree of self-sufficiency of 74.3% for the operational electric energy and that its carbon footprint is only 3.35 kgCO₂/m²y, 92% lower than in a typical office building in locations with the same climate.

欧洲能源政策引入了近零能耗建筑 (NZEB) 设计以刺激建筑能源转型，欧盟计划促进向正能源建筑 (PEB) 发展。大多数对 NZEB 的研究都是基于模拟，而不是基于真实的监测数据。本文介绍了 Zero 大楼的真实性能数据，这是一座获得 Leed Gold 和 Breeam 优秀环境设计认证的 NZEB 办公大楼，位于一个共享零排放区域供暖制冷设施的社区，仅依赖100% 可再生能源。评估建筑物及其社区的当前性能，以确定实现正能量建筑 (PEB) 目标的现有差距。一项研究表明，它实现了74.3%的运营电能自给率，其碳足迹仅为3.35 kgCO ₂ /m ² y，比相同气候地区的典型办公楼低92% .
