    • Project Rating Systems 12/02/08 INHS’s Experience with LEED
    • What We’ll Cover Today
      • Overview of Project Rating Systems
      • Details on LEED for Homes
      • A LEED Example - 301 Madison St
      • Final Advice
      • Overview of
      • Project Rating Systems
    • “ Green” Project Rating
      • What is it?
      • Why do it?
      • What are some ways of doing it
      • How much does it cost?
      • Why did INHS Pick LEED for Homes?
    • What is “Green” Project Rating?
      • 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
      • It’s a big world - Where to begin
      • How to weigh all the factors
      Green project rating is a system that helps you quantify the effect of your choices - Scott
    • Why Rate Your Project?
      • Makes the choices simpler
      • Contractors may make mistakes
        • Many eyes and verification help catch the errors
        • Having a written standard reduces questions
      • Keeps everyone honest – reduces “green washing”
    • Why Rate Your Project Yourself
      • Homeowners can
        • see what the issues and opportunities are
        • make informed decisions
      • Easier to build “inside the box”
      • Doesn’t require paying someone to do it for you
      • But experienced builders and architects know much more about the pros and cons of the choices you make
    • Some Project Rating Systems
    • Getting it Rated – What Does it Cost?
      • Paying for the Rating
        • LEED is $2-3,000 a building (INHS’s cost)
        • Energy Star = no net cost to INHS
      • Paying for the Upgrades You Want
        • Some techniques and materials are easy to do, effective, and free
        • More sustainable materials frequently cost more
      There are two costs
    • Getting it Rated – What Does it Cost?
      • Voluntary Systems – free
        • Any checklist you can download
      • Certified Systems - $$$
        • Architect or design professional
        • Energy Star
        • NAHB
        • LEED
      Verification takes time and time is money
    • Why Did INHS Choose LEED for HOMES?
      • Wanted to get credit for what we were already doing
      • Wanted to advance development of a sustainable building standard
      • Wanted a system that had verification
      • Wanted to show affordable housing can be built sustainably
      • Only real standard available at the time
      • So INHS joined the pilot phase of LEED for Homes
      • and
      • Found a grant to help fund it
      • Details on
      • LEED for Homes
    • Disclaimer
      • INHS currently uses LEED for HOMES. It suits our needs. We don’t advocate using it or not using it.
      • LEED for Homes is just one way of looking at your project.
    • What is LEED for HOMES
      • USGBC leading the way in sustainable building
      • “ Official” system for commercial and industrial ratings
      • Different types of buildings require different systems
      • USGBC wanted a national, certifiable standard for residential buildings
    • How does LEED for HOMES Work
      • Innovation and Design Process – special credits for unusual things
      • Location and Linkages – how does it relate to the area around it
      • Sustainable Sites – measures project impact on the site
      • Water Efficiency – measures water efficiency
      • Energy and Atmosphere – energy efficiency
      • Materials and Resources – how does it relate to the area around it
      • Indoor Environmental Quality – reducing pollutant exposure it
      • Awareness and Education – are the occupants aware of the features
      Projects are Broken Down into Categories
    • How does LEED for HOMES Work Projects get points for reaching certain objectives The points are tallied on a checklist
    • 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!
    • LEED - Pros and Cons
      • Pros
        • Certifiable (costs extra)
        • National
        • Repetitive, 2 nd time is easy
        • Looks at many facets – contractors are usually focused
      • Cons
        • It’s not cheap and INHS is getting a volume deal
        • The first time is harder
        • Too much paper and tracking for many people
        • Doesn’t reward good design
      • A LEED for Homes Example
      • 301 Madison St
      • 301 Madison St
      • 301 Madison St
      • Innovation and Design Process 5 pts. attained 9 possible
        • LEED representatives actually inspect the house to ensure compliance
      • Location and Linkages 10 pts. attained 10 possible
        • Site is on a previously developed site with full utilities
        • Site is not environmentally sensitive or farmland
        • Over ½ acre of green space is within ¼ mile
        • An outstanding number of community resources are within ¼ mile
      • Sustainable Sites 10 pts. attained 22 possible
        • Minimized disturbed area of the site
        • Very little impervious surfaces so water drains into the ground
        • Landscaping is drought tolerant and integrated with the house
        • Amount of lawn is minimized
        • Site is small allowing for dense development
        • Anti pest measures in place – termite shield and screening
      • 301 Madison St
      • Water Efficiency 4 pts. attained 15 possible
        • Very high efficiency faucets and shower
      • Energy and Atmosphere 20 pts. attained 38 possible
        • House is much more efficient than even Energy Star minimum. Reached the 5 Star level.
        • House is inspected and tested to ensure compliance
      • 301 Madison St
      • Materials and Resources 3 pts. attained 16 possible
        • Advanced framing techniques reduce waste
        • No tropical woods used
        • Waste generated was 50% below average for a new house – very hard to do in a small house
        • Environmentally products used – no carpet, linoleum, recycled porch decking, low VOC paint, recycled insulation
        • No refrigerants
      • Indoor Environmental Quality 16 pts. attained 20 possible
        • Follows the EPA Indoor Air Quality Package ( 75 pt checklist) including
          • Passive radon system
          • Special attention to water management
          • Heating systems carefully sized
          • No forced air ducting
          • All exterior materials finished all sides
          • Special air sealing and ventilation
      • Awareness and Education 1 pts. attained 3 possible
        • Home owner manual and walkthrough
      • 301 Madison St
      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
    • What Can You Learn from INHS’s Example?
      • Knowing what you want helps
        • Being the client and developer makes it easier
      • Go with people who know how to build sustainably
        • Remember, everyone has their own point of view
      • Some sort of verification is really worth it
      • The low hanging fruit is not very exciting
    • Big Lessons
      • A modest, well designed house can reach the Gold or high Silver level without spending extra money on “exotic” materials or techniques.
      • More efficient, higher quality, and more sustainable buildings do cost more than run-of-the-mill buildings.
    • The Bottom Line for You When You Build
      • Pick a System (or Systems)
      • Check Your Project Against Your System
      • Make a Checklist of Things to Verify during Building
      • Find a Way to Stay Honest
      • Don’t Chase Points
        • Do it Because It Works for You
        • If It Doesn’t Work for You, It Won’t Last or People won’t use it
    • The End
