Systems info: General disappointment with efficiencies of Geothermal from many attendees – too expensive and output not worth it. Air to air heat-pumps (by Japanese) have lowest energy cost but are hard to learn about (poor translations) Book recommendation: ‘Solar Hot Water Systems’ by Tom Lane Most architects recommended using the OSB layer as the air barrier layer, primarily on the inside. (Marc Rosenbaum made a case for using it on the outside, but this was considered a bit risky.) www.quantumbuilder.com

Cool ideas… PV panels should be installed to run the car, not the house! Check ‘sleep mode’ energy consumption for all appliances when purchasing Houses from 1800’s have correct window ratio’s for heat and natural lighting requirements Use SketchUp to model a house in 3-D and then model can be inserted on site with GoogleEarth to check solar shading www.quantumbuilder.com
