This WUI guideline is a result of the TREEADS project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101036926. The development of the guideline is led by RISE Fire Research in Norway, with valuable input from the partners in the Norwegian pilot in TREEADS, Jotne Connect AS, Woodify AS, Vipo AS, Backegårds List AB, and RISE Research Institutes of Sweden. We would like to extend our gratitude also to all involved stakeholders in the project, for their contribution to the guideline and for ensuring that the guideline is relevant for Norwegian conditions. We are particularly grateful for the collaboration with the Directorate for Civil Protection (DSB) on the development and final publication of the guideline.
