Innovative solar envelope technologies face multiple barriers, which prevent some of these innovations from contributing significantly against climate change. This report presents the barriers that the experts of Task 56 are aware of. The aim is to provide a comprehensive view (as much as possible) that developers of new integrated solar envelope systems could benefit of, at an early stage of their planning phase.enThermische Systeme und Gebäudetechnikbuilding-integrated solar systems (BISS)solar architecturesolar building envelopessolar facadesPhotovoltaikSolarthermieGebäudeenergietechnikPhotovoltaische Module und KraftwerkeThermische Kollektoren und KomponentenGebäudehülle690621697report
