  3. 3. <ul><li>Overview of </li></ul><ul><li>Project Rating Systems </li></ul>
  4. 4. “ Green” Project Rating <ul><li>What is it? </li></ul><ul><li>Why do it? </li></ul><ul><li>What are some ways of doing it </li></ul><ul><li>How much does it cost? </li></ul><ul><li>Why did INHS Pick LEED for Homes? </li></ul>
  5. 5. What is “Green” Project Rating? <ul><li>Green building is the practice of increasing the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment during the building's lifecycle, through better siting, design, construction, operation, maintenance, and removal - Wikipedia </li></ul><ul><li>It’s a big world - Where to begin </li></ul><ul><li>How to weigh all the factors </li></ul>Green project rating is a system that helps you quantify the effect of your choices - Scott
  6. 6. Why Rate Your Project? <ul><li>Makes the choices simpler </li></ul><ul><li>Contractors may make mistakes </li></ul><ul><ul><li>Many eyes and verification help catch the errors </li></ul></ul><ul><ul><li>Having a written standard reduces questions </li></ul></ul><ul><li>Keeps everyone honest – reduces “green washing” </li></ul>
  7. 7. Why Rate Your Project Yourself <ul><li>Homeowners can </li></ul><ul><ul><li>see what the issues and opportunities are </li></ul></ul><ul><ul><li>make informed decisions </li></ul></ul><ul><li>Easier to build “inside the box” </li></ul><ul><li>Doesn’t require paying someone to do it for you </li></ul><ul><li>But experienced builders and architects know much more about the pros and cons of the choices you make </li></ul>
  8. 8. Some Project Rating Systems
  9. 9. Getting it Rated – What Does it Cost? <ul><li>Paying for the Rating </li></ul><ul><ul><li>LEED is $2-3,000 a building (INHS’s cost) </li></ul></ul><ul><ul><li>Energy Star = no net cost to INHS </li></ul></ul><ul><li>Paying for the Upgrades You Want </li></ul><ul><ul><li>Some techniques and materials are easy to do, effective, and free </li></ul></ul><ul><ul><li>More sustainable materials frequently cost more </li></ul></ul>There are two costs
  10. 10. Getting it Rated – What Does it Cost? <ul><li>Voluntary Systems – free </li></ul><ul><ul><li>Any checklist you can download </li></ul></ul><ul><li>Certified Systems - $$$ </li></ul><ul><ul><li>Architect or design professional </li></ul></ul><ul><ul><li>Energy Star </li></ul></ul><ul><ul><li>NAHB </li></ul></ul><ul><ul><li>LEED </li></ul></ul>Verification takes time and time is money
  11. 11. Why Did INHS Choose LEED for HOMES? <ul><li>Wanted to get credit for what we were already doing </li></ul><ul><li>Wanted to advance development of a sustainable building standard </li></ul><ul><li>Wanted a system that had verification </li></ul><ul><li>Wanted to show affordable housing can be built sustainably </li></ul><ul><li>Only real standard available at the time </li></ul><ul><li>So INHS joined the pilot phase of LEED for Homes </li></ul><ul><li>and </li></ul><ul><li>Found a grant to help fund it </li></ul>

How does LEED for HOMES Work <ul><li>Innovation and Design Process – special credits for unusual things </li></ul><ul><li>Location and Linkages – how does it relate to the area around it </li></ul><ul><li>Sustainable Sites – measures project impact on the site </li></ul><ul><li>Water Efficiency – measures water efficiency </li></ul><ul><li>Energy and Atmosphere – energy efficiency </li></ul><ul><li>Materials and Resources – how does it relate to the area around it </li></ul><ul><li>Indoor Environmental Quality – reducing pollutant exposure it </li></ul><ul><li>Awareness and Education – are the occupants aware of the features </li></ul>Projects are Broken Down into Categories
  16. 16. How does LEED for HOMES Work Projects get points for reaching certain objectives The points are tallied on a checklist
  17. 17. How does LEED for HOMES Work Total Number of Points is compared to a standard Certified – 45 points Silver – 60 points Gold – 75 points Platinum – 90 points For LEED, the points needed to reach a standard depends on the size of the house!

  24. 24. <ul><li>301 Madison St </li></ul>Larger homes are more wasteful to build and to live in: this 2 BR home is ~1200 sq ft, 30% smaller than the national average, so we needed 5 fewer points to achieve our rating. LEED for Homes Rating Levels Certified 40 points Silver 55 Gold 70 Platinum 85 301 Madison St received a Gold rating with 73 points
  25. 25. What Can You Learn from INHS’s Example? <ul><li>Knowing what you want helps </li></ul><ul><ul><li>Being the client and developer makes it easier </li></ul></ul><ul><li>Go with people who know how to build sustainably </li></ul><ul><ul><li>Remember, everyone has their own point of view </li></ul></ul><ul><li>Some sort of verification is really worth it </li></ul><ul><li>The low hanging fruit is not very exciting </li></ul>
