Neighbor Jeff Cole (Silver Peasant Productions) will be producing video vignettes on the TrekHaus project.  Jeff's first segment is on phase change material (PCM).  Check out the "rough cut" at

BioPCM, a soy-based phase change material, is an easy way to increase thermal mass and improve thermal comfort by minimizing indoor temperature fluctuations.  When the house gets hot (above 76 degrees F), BioPCM stores heat by changing from solid to liquid.  As the house cools down (below 76 degrees F), BioPCM changes from liquid to solid and releases heat.  The thermal mass of one sheet of BioPCM (about half inch thick) is like adding 12 inches of concrete!  BioPCM can be installed in walls, floors, ceilings, and attics of new builds as well as retrofits.
