This paper discusses the question of what content – in form of use cases - a Digital Building Product Passport (DBPP) should cover in order to meet the different information requirements of stakeholders along the value chain of cross-laminated timber (CLT). The aim of this case study in connection with the TimberConnect research project is therefore to use workshops, expert interviews and a qualitative content analysis to show which use cases are relevant for the value chain of CLT elements in order to increase the willingness to voluntarily introduce a digital building product passport. The forecasts for 2030 and 2040 show that, on average, the use cases AI-supported analyses, Digitalization of reporting obligations and Material recovery are identified as the three most relevant use cases in the value chain of CLT elements. The relevance of CO2-balancing will increase by 2030, but may decrease by 2040 in certain sectors. Meanwhile, Process optimization and Production optimization will maintain their pertinence, particularly within the manufacturing and construction sectors. Overall, sustainability and digital transformation are accelerating, though their adoption varies by industry. From the authors' point of view, the patterns provide a solid basis for the development of a digital building product passport for timber components.
