1 ENERGY STAR Qualified Homes 2011 Specifications Overview

2 ENERGY STAR FOR HOMES GROWTH THE ROAD TO ONE MILLION HOMES Number Labeled Homes Year , , , ,000 1,000,000 0 Cumulative Annual

3 ENERGY STAR FOR HOMES GROWTH ONE IN FIVE HOMES IN 2009 % Market Penetration Year

4 ENERGY STAR FOR HOMES GROWTH NEW BUILDER PARTNERS PER MONTH Before Soft MarketAfter Soft Market ~1,000% Growth!

5 CONTEXT: ENERGY STAR vs. GREEN ENERGY STAR for Homes Green Programs for Homes Voluntary Recognizes Builders Label Web Site, Marketing, Awards

6 CONTEXT: ENERGY STAR vs. GREEN ENERGY STAR for Homes Green Programs for Homes Voluntary Recognizes Builders Label Web Site, Marketing, Awards Defines Efficient Rigorous Specifications Third-Party Verified Offers Flexibility Points Multiple Tiers

7 ‘GREEN’ BEGINS WITH ‘BLUE’ Energy Efficiency Air Flow Thermal Flow Moisture Flow Equipment Indoor Environment Source Control Ventilation Filtration Resource Efficiency Water Materials Waste Recycling Land Renewables

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

HVAC System Quality Installation: Efficient Equipment Right-Sizing Air Distribution Refrigerant Charge Duct Installation Pressure Balancing Ventilation Filtration

86 Answer… Yes… if making 90% of competition obsolete is good for business…

87 But…better is not good enough!!! You have to back up and sell compelling value propositions.

88 Better is Not Good Enough… You Have to Sell ENERGY STAR  Label Every Home  Train Sales Agents  Hold Agents Accountable  Create ‘Value’ Experiences And Remember…  Design & Location Trump
