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…
Answer…Low Cost Infrared Cameras
OBSOLETE COMPETITIONOBSOLETE COMPETITION
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
BUILDING SCIENCE
FIBROUS NSULATION = AIR BARRIER
Resists Heat Flow
Air Flow…need Air Barrier…(any solid material that blocks air flowincluding sealing at edges and seams)…on all six sides……in direct contact with insulation (alignment)
BUILDING SCIENCE INSULATION IS NOT AN AIR BARRIER

- min. 24” (Zones 4 and 5); 48” (Zones 6, 7, and 8)

Now it’s time for 2011 spec…
What value proposition will make used and minimum code homes
even more obsolete?

QUESTION: ARE COMPLETE SYSTEMS BETTER FOR BUSINESS?
HVAC SystemQuality Installation:•Efficient Equipment•Right-Sizing•Air Distribution•Refrigerant Charge•Duct Installation•Pressure Balancing•Ventilation•Filtration
Answer…
Yes… if making 90% of competition
obsolete is good for business…
But…better is not good enough!!!
You have to back up
and sell compelling
value propositions.
Better is Not Good Enough… You Have to Sell ENERGY STAR
