12. How we sold 2006 spec,first we asked a question… What technology will revolutionize the housing industry? Hint: it has nothing to do with construction…

13. Answer… Low Cost Infrared Cameras

14. OBSOLETE COMPETITION

15. BUILDING SCIENCE RULES TO LIVE BY • Driving Forces Move More to Less:- More Heat to Less Heat- More Pressure to Less Pressure- More Humidity to Less Humidity • Gravity Makes Things Fall

16. Resists Heat Flow Air Flow …need Air Barrier… (any solid material that blocks air flow including sealing at edges and seams) BUILDING SCIENCE FIBROUS NSULATION = AIR BARRIER …on all six sides… …in direct contact with insulation (alignment)
