  1. Southface Energy Instituteresponsible solutions for environmental living • Education • Research • Policy • Technical Assistance-commercial-residential-communities • Greenprints March 12-14, 2008 www.southface.org

  2. Architect Lord, Aeck & Sargent, Inc. Contractor— Eco Office Contractors: A Consortium of Green Builders DPR Construction Hardin Construction Co., LLC Holder Construction Co. R. J. Griffin & Co. Skanska USA Building The Winter Construction Company Eco Office

  3. Eco Office • Off-the-shelf technology • Integration is key • ID and eliminate market barriers

  4. Buildings Have BIG Impact • Use 30-40% of total US energy • 60-70% of electricity • 35-40% of municipal solid waste • 25-30% of wood & raw materials use • 15-25% of water use

  5. “Unknowingly, the architecture and building community is responsible for almost half of all U.S. greenhouse gas emissions annually. Globally the percentage is even greater.”

  6. SoutheastFL,GA,SC,NC,TN,VA

  7. GHG Emissions in the Southeast are important globally

  8. Transportation 34% Electric Utilities 39% Industrial 10% Residential 3% Commercial 2% Fugitive Emissions 0.4% Industrial Processes 4% Waste 3% Agriculture 3% Southeast GHG Sources…

  9. Southeast has much room for improvement in energy efficiency ACEEE’s 2006 State Energy Efficiency Scorecard 29. Florida 30. North Carolina 30. South Carolina 38. Virginia 38. Georgia 43. Tennessee

  10. Electric Utility Spending on Energy Efficiency $/capita/yr New England $12.10 Northwest 4.00 Midwest 2.98 Southeast 0.67* *More than 50% is for Florida and mostly for peak reduction Southeast has the highest household electricity consumption

  11. Projected Population Increase

  12. Lots of New and Renovated Buildings For Atlanta, most buildings in the year 2025 have not yet been designed or constructed • 52% of residential • 71% of non-industrial • 62% of industrial 75% of US buildings by 2035

  13. California Proves Energy Efficiency Works • Saved 12,000 MW (~24 power plants) • Saved $875 to $1300 per person Sources: California Energy Commission and RAND United States California Source: California Energy Commission, 2005

  14. Water and Electricity • Potable water requires vast amounts of energy for purification and delivery; waste treatment requires energy • Power generation utilizes large quantities of fresh water creating thermal pollution and consumptive loss Water conservation = Energy conservation Energy conservation = Water conservation

  15. Electricity and Water 35 Mgal/d Eco Office Base Case Electricity =144,094 kWh → 432,282 gallons/year Design Case Electricity = 64,804kWh → 194,412 gallons/year 142 Mgal/d 662 Mgal/d 1,000 Mgal/d 3,310 Mgal/d 1,250 Mgal/d Georgia Total water use- 6,490 million gallons per day (Mgal/d)1.65 gallons per kilowatt-hour

  16. Projected energy bill savings with a national RPS $260 $130 $100 $160 Cumulative savings on electricity and natural gas bills (2020) with national RES in House energy bill (15% by 2020) 2005$ in millions $280 $490 US Total: $13 to $18+ billion saved by 2020

  17. U.S. Solar Resources Germany But same holds for NJ, MD, & GER where incentives are driving solar development Southeast capacity does not match Southwest

  18. The Eco Office Overview • 10,000 sf offices & training space • Green Building Showcase • 75% water use reduction • Capture 2-year storm • 60% energy use reduction • Tracking LEED-Platinum Image courtesy of Lord, Aeck, and Sargent Architects

  19. Designed Building Savings Successful Energy Efficiency Measures $2.00 $1.89 • Desiccant System • Energy Recovery • Daylighting • Lower LPD • Shading • Efficient Systems • Improved windows with Wood Frames • Polysteel ICFs $1.80 $1.60 $1.40 $1.04 $1.20 $/ft2 $1.00 $0.85 $0.80 $0.60 $0.40 $0.20 $0.00 Base Building
