Here’s a snapshot of progress on the new Passive House. The DC region has sustained unprecedented rainfall over the past four days. By the luck of the draw, Janet and I were on vacation, at a beach in South Carolina–where the weather was sublime. While there, we went kayaking on a backwater that flows into the Story River. There we saw an osprey, up in a tree–which in form bore a remarkable resemblance to these naked rafters. The weather is clearing now. Soon the air barrier surfaces will be complete, enabling us to do a preliminary air barrier test.
