In this workshop we discussed the progress and results of six Horizon 2020 projects—INSTRUCT, BIMEET, The nZEB Roadshow, TRAIN4SUSTAIN, HP4All, and BUSLeague—about how to increase the number of skilled building professionals and/or blue-collar workers across the building design, operation, and maintenance value chain (designers, architects, engineers, building managers, technicians, installers, blue-collar workers including apprentices, and other building professionals), with a specific focus on the engagement of small and medium-sized enterprises (SMEs).
