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)

Insulation can be run:- vertical; horizontally under the slab; or out from building

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?


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
