Throughout the NAPHN 17 Conference in Oakland California visitors will be able to take part in the live public experiment pitting two approaches to construction against one another: Contemporary California vs Passive House.
The contest will follow on the popular ‘Plus/Minus Box’ challenge from the 20th annual Passive House Conference in Darmstadt Germany in 2016. Two boxes are built, same size, two windows each. The envelope (insulation, air-tightness, insulation levels) of the first box meets the current California energy code while the other is constructed to meet the rigorous Passive House Standard. Each box will begin the competition with large blocks of ice that will slowly melt throughout the week of the conference. Will the box built to Passive House standard end up with more or less ice than the code-built box? Does the Title 24 (part 6) compliant box have a chance? Can insulation and airtightness really make a difference in the California climate?
