This project aims to stimulate the circular economy by introducing a Sustainability Enhanced Construction Information Classification System (CICS) to be used by Portuguese-speaking building designers, contractors and managers. It will allow the unification of terminology at all scales, facilitating communication between agents and supporting material and component selection and accurate assessment of the building's impacts over the life cycle in all dimensions. The ultimate goal is to improve buildings’ performance and to reduce waste through the use of digital tools that provide informed management and selection of construction materials and elements.
