How all of these assemblies work in all the climate zones? How these assemblies can transition to one another?

The evening between the two days will feature a game first made popular with architects and contractors called “I never…”

The way this game works is that someone will say something like “I never installed a vapor barrier in this wall"…those in the group that have installed a vapor barrier in such a wall will need to have a drink… The evening event will be held at Dr. Lstiburek’s home. Dr. Lstiburek is known for a well stocked bar. Transportation to and from this event will be provided…as drinking and driving in Massachusetts is not legal - and besides, you spill too much. Non alcoholic beverages will be available for those that prefer them. Food will also be provided. It will be tasty and unhealthy.
