This is the data repository for the scientific database EUBUCCO v0.1 (EUropean BUilding stock Characteristics in a Common and Open database for 206 million individual buildings). Introduction: EUBUCCO is a scientific database of individual building footprints for ~206 million buildings across the 27 European Union countries and Switzerland, together with three main attributes -- building type, height and construction year -- included for respectively 45%, 74%, 24% of the buildings. EUBUCCO is composed of 50 open government datasets and OpenStreetMap that have been collected, harmonized and partly validated. EUBUCCO provides the basis for high-resolution urban sustainability studies across scales -- continental, comparative or local studies -- using a centralized source and is relevant for a variety of use cases, e.g. for energy system analysis or natural hazard risk assessments. Data: The data of EUBUCCO v0.1 (and of all future versions) can be found at eubucco.com/data Version history: EUBUCCO is currently available under its first, beta version (v0.1). The first stable version (v1.0) is planned to be released later in 2022. This database is associated with a Data Descriptor paper. This version corresponds to the first journal submission.
