This document defines the concepts and definitions and is the first part of a set of standards to define the framework for digital twins in the built environment. It includes the terms and definitions, the relation with building information modelling and addresses the lack of standards for the qualitative specification of a digital twin, which can include geometric, attributive, structural and infrastructural quality, as applicable. This document is based on the experiences obtained in use cases [1] and documents from other technical committees, including ISO/IEC 30173. This document can be used in the development of other standards and in support of communications among diverse, interested parties or stakeholders. This initiative aims to define an ecosystem of digital twins opening the opportunity to release even greater value, using data for the public good.
