This CEN Workshop Agreement (CWA) provides orientation for the: – design process of an innovative and adaptable envelope over existing façades for building refurbishment, describing the possible different technologies and components, and providing guidelines on the selection criteria, limitations for the implementation, estimated costs and payback calculations. This information is intended to help building envelope designers to make informed decisions considering the building particularities. – production, transport, storage and installation aspects for each system component of an innovative and adaptable envelope for building refurbishment, providing advice for installers on the overall logistics for the real implementation. – assesment and evaluation of innovative and complex envelope system at building level that is not completely addressed by existing standards. Tests to be selected to feasibly asses an envelope system composed by different components. This CWA is not designed to support European legislative requirements, such as the Construction Products Regulation 305/2011, or to address issues with significant health and safety implications.
