Transcript

  1. Welcome to Green Framing Options <br />Presenter: Wally Geer<br />go2wallyworld@hotmail.com<br />
  2. Some Sincere Thanks to:<br />The Center for Sustainable Energy<br />U.S. Green Building Council, C4 Chapter<br />National Association of Home Builder’s Research Center<br />University College of Dublin<br />MosArt Architects, Dublin<br />Laura’s Painting, Ojai, CA.<br />Greymar Associates, Ventura, CA.<br />Sonoma State University<br />
  3. In Defense of Wood<br />There is an abundant supply of vendors and subcontractors <br />It has relatively few design & structural constraints <br />It’s cost effective<br />It’s beautiful<br />
  4. Why Chose an AlternativeFraming System ?<br />Site & Structural Constraints<br />Health Related Issues<br />Environmental Concerns<br />Energy Efficiency<br />Life Cycle Value<br />Fire Safety<br />Competitive Advantage<br />
  5. Site & Structural Constraints<br />Lack of Staging Area<br />Complex topography that will not allow conventional movement of building materials<br />Unique Soils of Geological Conditions<br />Short Building Season<br />
  6. Health Related Issues<br />Mold<br />Building Material Toxins<br />Specific Health Issues of the Occupants<br />Healthier Families & Higher Workplace Productivity<br />
  7. Environmental Concerns<br />Concerns over renewable resources<br />Concerns over “Cradle to Cradle” <br /> or “Cradle to Grave” issues<br />Concerns related <br /> to “Carbon Footprint”<br />Concerns over material <br /> waste and Land Fill waste<br />
  8. Energy Efficiency<br />“Tight” Building Envelope<br />Passive Solar Design Benefits<br />Life Cycle Energy Savings<br />High Performance Building Assemblies <br />
  9. Life Cycle Value<br />“Life Cycle Value” <br />is the total Cost of INITIAL CONSTUCTION + <br />ENERGY CONSUMPTION COSTS over the <br />functional life of a building<br />
  10. Cost Comparison Construction Costs of a 50% ZEB Office Building, Kiel, Germany(Building Shell + Tenant Improvements - Converted to U.S. Dollars)<br />Conventional Sustainable Difference<br />Frame 48.28 53.82 11.46%<br />Envelope 83.65 101.27 21.06%<br />Roof 15.20 15.11 -0.58%<br />Walls/Doors 12.78 12.90 0.95%<br />Finishes 33.48 32.24 -3.70%<br />Services 92.18 86.64 -6.01%<br />Site works 7.04 7.02 -0.37%<br />TOTALS 292.62 309.00 5.60%<br />
  11. Energy Savings<br />Office Building Type Energy<br />Conventional 25 KWH/ft2/year<br />Sustainable 10 KWH/ft2/year<br />Savings 15 KWH/ft2/year<br />For a 250,000 Office Building, that’s a Savings of over $350,000 per year<br />
  12. Fire Safety<br />Desire to have a “Fire Safe” home<br />Lower Insurance Rates<br />Higher resale value in “Fire Country”<br />
  13. Competitive Advantage<br />
  14. Why NOT to chose an Alternative Framing System <br />Lower Initial Cost of Structural Shell Construction<br />Because you can gain “LEED Credits”<br />If there are limited options in your market area of suppliers or qualified subcontractors <br />Because your flaky unlicensed Brother-in-Law claims he is knowledgeable of straw bale construction <br />
  15. DON’T think “Framing Systems”,THINK “Building Envelope Assemblies”<br />
  16. When evaluating Building Envelope Assemblies, consider:<br />Structural System<br />Adaptability of Floor & Roof Diaphragms<br />Exterior Building Skin<br />Interior Building Skin<br />Insulation<br />Adaptability of Plumbing & Electrical within the system <br />Design & Structural Constraints of the Assembly<br />
  17. When comparing Options, consider<br />Design & Structural Constraints<br />Energy Efficiency<br />Environmental Attributes<br />Initial Construction Cost<br />Life Cycle Value<br />Fire Safety<br />Adaptability of Building Skin Options<br />Adaptability of Electrical & Plumbing<br />Availability of Raw Materials<br />Availability of Qualified Labor & Subcontractors <br />
  18. What are the Options<br />Conventional Wood Framing<br />FSC Certified Wood Framing<br />Light Gauge Steel Framing<br />Red Iron Steel Framing<br />Structurally Insulated Panels (aka “SIPs”)<br />Insulated Concrete Forms (aka “ICFs”)<br />Timber Frame Structural Systems<br />Straw Bale Construction<br />
