Published on

This workshop will summarize the alternative building structural systems available for energy-efficient and sustainable building projects. Wally Geer of Greymar Associates along with a panel of industry experts will talk about the benefits of building with green framing products such as structural insulated panels, recycled steel framing,Insulated Concrete Forms and other alternative building methodologies including straw bale and ram earth structures.

Green Framing Options

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