The impact of policy instruments on the first generation of tall wood buildings

In a context of environmental concern and limited urban land, the construction industry faces the challenge of providing solutions for the increasing urban population both efficiently and sustainably. Numerous innovations on engineered wood products for multistorey buildings arise as one of the most promising solutions. In this context, various policies have facilitated the development of Tall Wood Buildings (TWBs). Yet, few publications analyse these policies and their influence on specific projects. This research aims to examine the impact of Policy Instruments (PIs) on individual TWBs qualitatively. Data collection is based on documentary review and semi-structured interviews with policymakers and professionals involved in 37 projects across eight countries. This study reveals that numerous TWBs have been facilitated by policies, acting through diverse PIs applied combined or in isolation. Notably, while Regulatory Instruments allowed TWBs in the first place, Research and Development Tools supported their development and approval process. Often, Research and Development Tools subsidised demonstration projects through Economic Instruments, after competitions or applications (Voluntary Policy Tools). Moreover, many Information Tools (e.g. campaigns, technical assessments) complemented other PIs. Remarkably, while some TWBs have become legal and technological precedents, technical information resulting from their development has influenced proposed changes in building codes.
