  6. Green Building 25% Accredited #of Buildings The Majority Standards-Regulations-Codes Silver Gold Platinum Green Standards It is about a Market Shift

  7. Why do we do it? Yes Buildings consume: • 40% of total energy • 65% of total electricity • 30% of raw materials • 12% of potable water • Contaminants indoors can be two to five times worse than those outdoors • Asthma increased in young children by 160% since 1980 but,

  8. Lets face it If you can not sell it, it is worthless. http://www.youtube.com/watch?v=OaiSHcHM0PA So to be viable you have to “Show me the Money!”

  9. How do you define GREEN? • Energy Efficient • Health & Safety Builder B Builder C • Energy Efficient • Health & Safety • Durable • Water Efficient • Environmentally Responsible • Sustainable Community Builder A • Energy Efficient • Health & Safety • Durable • Water Efficient

  10. Factors in Choosing a Program • What level of performance is desired? • What shade of Green is desired? • Do the measures deliver value to the builder and new homeowner? • Is the program clear, consistent, reliable, and reproducible? • Does the program provide market viability and name recognition? http://www.realestateiii.com/new_construction/druid_ave.php?

  11. Components Addressed in a Green Building Program • Energy Efficiency • Water Use • Indoor Air Quality • Materials • Waste • Local Building Codes • Site Selection

  12. EPA’s ENERGY STAR • Government-backed well recognized National program with more then 850,000 built so far • Focus is on the energy efficiency, and baseline for most other rating systems • Has water, indoor air, and advance building packages available to make it a comprehensive Green Building program • Program is changing in 2010 to raise the bar and be more inclusive • Advance New Home Construction Program in Pilot stage • Basic Costs ~$2,700 (85) • ANHC ~$25,000 (60)

  13. Built off the HERS Index • Scale provided by RESNET • Index score of 100 represents a house build according to the 2004 IECC • Index 0 represents a net zero home • Each 1-point decrease corresponds to ~ a 1% reduction in energy consumption

  14. EPA’s ENERGY STAR • Pros: • Baseline for most of the other certifications • Many builders are currently building to minimum ENERGY STAR standards (85) without certification • Has additional modules to customize the ‘Greeness’ • Simple certification process with independent oversight • Brand recognition, online resources and marketing tools • Cons : • Additional modules needed to be a complete green building program until 2010 • Energy Based until 2010 (Light Green) • Not designed specifically for mixed climates

  15. DOE’s Builders Challenge • Government-backed National program working on building 220,000 HP homes by 2012 and Net Zero by 2030 • Focus on the energy efficiency and comfort by addressing the building systems and envelope • Houses must achieve < 71 in the E-scale • Certification through partners (NAHB Emerald or EarthCraft Gold), prescriptive or performance • Costs ~$18,000 (70)

  16. Builders Challenge • Pros: • Sets a true standard for real Energy Efficiency • Based in Building Science and regionally proven techniques to improve energy consumption • Simple certification process with independent oversight • Good online resources and marketing tools • Cons: • No additional modules available to be a complete green building program as a stand alone (NHBA Compatible) • No brand recognition in our market • Light Green (Energy Based) • Bar for Challenge changes frequently based on achieving net zero by 2030

  17. Florida based National Green Building program launched in 2003 • Builds from the Build America Program and mainly focuses energy and comfort issues • Advance certifications take into account combustion safety and CO • Uses a checklist administered by contractor with limited verification QA/QC • Three tiers of certification with guarantee • Cost ~ $6,000

  18. Pros: • National comprehensive green building program with focus on energy consumption • Designed to be builder friendly without policing by a independent third party organization or energy rater • Brand well recognized in hot climate states • Cons: • Has not had much market penetration in VA • Administered by MASCO to promote their product line • Not specifically designed for mixed climates • No independent QA/QC • No additional modules to address IAQ, Water, Etc. (Light Green)

  20. NAHB: National Green Building Program Pros: National comprehensive green building program Acceptable standards meant to complement code Good online resources and streamlined processes Adopted by NVBIA (HBA) Cons: First developed in Canada by the forestry council to compete directly with USGBC’s LEED Program New system not yet vetted by builders and officials Not specifically designed for mixed climates Multiple certifications ranging from Light Green to Dark Green create a confusion for buyers

  23. LEED for Homes (not LEEDs) • USGBC residential program designed by architects and engineers • Considered for code adoption in several progressive localities including Arlington, VA • Rating system with 4 tiers • Launched in 2005 and will be released in Jan of 2009 for open certification (1,041 certified homes during the pilot) • It is certified though Providers with Green Rater inspections • Cost ~ $15,000

  25. At a Glance

  26. Recommendations Do ENERGY STAR as a standard Affordable home builders should consider offering packages for IAQ, Water, Lighting and advanced certifications Custom home builders should consider specializing in an advance building practice (i.e. ICF, SIP, etc.) and stick with a certification program that fits their style Meet with a third party verifier to discuss your project list to see what program is right for your business plan
