ABSTRACT
Mass timber construction systems, such as cross-laminated timber (CLT), which originated in Europe, are gaining acceptance within North America as a viable alternative to multi-story steel-frame or concrete structures. The purpose of this study is to analyze types of innovation in the design of the building enclosure precipitated by the introduction of CLT in the North American market. Additionally, knowledge management and transfer mechanisms supporting the use of CLT in the field are investigated through the analysis of case examples. A number of factors are identified that characterize the implementation of innovation in mass timber building enclosure, among which is the interplay of structural and enclosure design in those elements at higher risk of moisture intrusion. These system innovations required concurrent design collaboration dynamics and effective knowledge management among the different project’s stakeholders and partners. This analysis can contribute to a better understanding of the current state of practice in architectural design, as well as in the mechanisms supporting knowledge management and R&D initiative in an emerging construction market.
