  2. 2. Agenda: • 10:30 – 10:35 introduction • 10:35 – 11:00 Overview of LEED for Homes • 11:00 – 11:25 Green Building Strategies • 11:25 – 11:35 Break • 11:35 – 12:15 ENERGY STAR & LEED • 12:15 – 12:30 Q&A • Adjourn
  3. 3. What is Green Design? To significantly reduce or eliminate the negative impact of buildings on the environment and on the building occupants, green building design and construction practices address: sustainable site planning, safeguarding water and water efficiency, energy efficiency, conservation of materials and resources, and indoor environmental quality. -USGBC
  4. 4. What is Green Design? How do we love all children of all species for all time? -William McDonough
  5. 5. What is LEED? Leadership in Energy and Environmental Design The LEED Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings.
  6. 6. CATEGORIES OF LEED new LEED-NC construction existing LEED-EB buildings Commercial commercial Buildings LEED-CI interiors core & LEED-CS shell LEED for Homes Residential neighborhood LEED-ND development
  7. 7. • In pilot since late 2005, due to launch later this year – Green Build • Open to any qualifying projects • Follows residential code – 3-stories and below • Concurrent pilots for mid-rise (4-6) and high-rise (7 and up) residential buildings running now • Differs from other LEED products in delivery system – administered locally by ‘Providers’
  8. 8. LEED for Homes Categories Innovation & Design Process (ID) Integrated project team, plan for durability, allow for innovation Location & Linkages (LL) Locate homes efficiently, link to existing infrastructure Sustainable Sites (SS) Preserve natural ecosystem on the building lot Water Efficiency (WE) Reduce potable water usage, use rainwater/grey water Energy & Atmosphere (EA) Reduce emissions caused by energy use, ENERGY STAR Materials & Resources (MR) Reduce environmental impact of building materials Indoor Environmental Quality (IEQ) Provide a comfortable and healthful indoor environment Awareness & Education (AE) Educate homeowners (operators) about green building
  9. 9. LEED for Homes Checklist • 130 potential credits • 18 prerequisites • 16 required credits • 4 Certification levels 1. Certified 2. Silver 3. Gold 4. Platinum • Flexible • Evolving
  10. 10. LEED for Homes Rating Guide www.usgbc.org/LEED/Homes/LEED for Homes Pilot Rating System v1.11a (PDF) (http://www.usgbc.org/DisplayPage.aspx?CMSPageID=147 184 page companion to the checklist. For every credit: • Intent • Requirements • Verifications/Submittals • Synergies/Tradeoffs • Additional Information
  11. 11. Mandatory Measures • Integrated design process • Durability plan • Site protection • Energy Star Home • Reduced construction waste • Tropical hardwood restriction (FSC, no lauan) • Health and safety measures • Owners manual
  12. 12. Mandatory Measures and Points Category Mandatory Points Points Measures Required Available Innovation & Design 4 0 9 Location & Linkages 0 0 10 Sustainable Sites 2 5 21 Water Efficiency 0 3 15 Energy & Atmosphere 1 0 38 Materials & Resources 3 2 14 Indoor Environmental Quality 7 6 20 Awareness & Education 1 0 3
  13. 13. Accountability Form

  16. 16. Integrated Project Planning – Engage key members of project team • Pre-construction meeting – Goals, timetables, responsibilities ID 1.2 Integrated Project Team 1pt. ID 1.3 Design Charrette 1pt.
  17. 17. Durability Plan ID 2.1 Detailed Durability Plan; (Pre-Construction) Mandatory ID 2.2 Third-party verification of Durability Plan 3 pts
  18. 18. CIR’s and ID’s Credit Interpretation Request— an alternative way of achieving the same intent as an existing LEED credit. It is achieved by requesting permission to meet the “intent” of a credit using an approach that is different from the stated “requirements,” or simply a clarifying question not addressed in the rating guide. Innovative Design (ID) — a way of earning one or more LEED points for technologies or strategies that are not included in the Rating System but offers substantial environmental benefits. It is achieved by requesting permission for a credit / measure that is not included in the current rating system or going above and beyond an existing credit.
  19. 19. What is LEED-ND? A LEED rating system being developed through a partnership with – Natural Resources Defense Council (Smart Growth) – Congress for the New Urbanism A rating system that combines elements of smart growth, urbanism, and green building LL 1 LEED-ND Neighborhood 10 pts
