Mass Voodoo - Debunking Passive Solar at NAPHN15

The North American Passive House community gathered in Vancouver this October at NAPHN15 to celebrate a number of recent successes.  A significant number of new projects have been built across North America and many more, particularly large one's, are in the planning stages.  Allen Gilliland delivered a jury-selected presentation on the use, and mis-use, of thermal mass in buildings, specifically in the California Bay Area.  He sticks a pin directly into the heart of the passive solar 'mass and glass' Voodoo Doll.
