This year-end report for the continuing project “Decision Aids for Durable Wood Construction” focuses on international activity in building envelope research. One of the major task areas within Decision Aids is knowledge maintenance about related work elsewhere; 2004/2005 was a particularly active year for building science conferences, which are the primary venue for research reporting in this field. Short summaries of current work are provided, organized by institution. In addition, the other activities under Decision Aids are also reported, including an expansion of the durability web site and an update on the proposal for an outdoor test facility in Vancouver.
