The EQWIN-P project aims to create a seamless process chain from planning, targeted sampling, and procurement to the industrial production of façade components and their ultimate implementation, maintenance, and operation as the building’s envelope. An API and metadata schema will be developed to facilitate information flow between stakeholders and eliminate media interruptions, forming the foundation of the EQWIN-P network. The project is supported by a consortium of component manufacturers, software companies, and planners and will make data and calculations publicly accessible through a common API. The results of EQWIN-P will make it easier for component manufacturers to share their product data and make energy-efficient buildings more economical.
