This book presents the Proceedings of the International Conference on Sustainable and Digital Building, at Marinha Grande, Portugal held in October 2022. The Conference created a forum for discussion of a range topics on this broad area, including building materials, building processes, digital technologies, and building sustainability. A major focus of the collection is green building throughout a structure’s life-cycle—from planning to design, construction, operation, maintenance, renovation, and demolition. In addition, the Conference examined industry making the transition to digital transformation of buildings, a key benchmark to realizing European climate goals and achieving net-zero carbon buildings by 2050.
