Back in November 2010, the Passive House Institute US held its annual North American Passive House Conference in Portland, Ore., bringing together experts with architects, builders, and consultants seeking to learn more about the super energy-efficient building method for two days of educational sessions. Now (most of) the presentations from those sessions are available for download on the PHIUS website, so even if you weren’t able to attend the conference you can still benefit from the knowledge shared by some of the top minds in the field.
