Transcript of "CIB TG66 North America Webinar 2010-10-12 5 Joshua Kneifel"

  1. 1. CIB Webinar: Implementation of Energy Efficient Buildings Policies in 5 Continents North AmericaBeyond the Code: Energy, Carbon, and CostSavings using Conventional Technologies Joshua Kneifel, PhD Engineering Laboratory National Institute of Standards and Technology (NIST) U.S. Department of Commerce
  2. 2. U.S. Goals Impacting BuildingsNew Energy for America Dramatically improve building energy efficiency Reduce greenhouse gas emissions 80% by 2050Federal R&D Agenda Integrated, Performance-Based Design and Operation Performance- Net- Net-Zero Energy Building Technologies and StrategiesHow do you reach these goals for buildings?What metrics do you use to measure accomplishments?
  3. 3. Policy Options and Metrics How to drastically increase building energy efficiency andreduce carbon emissions? Regulation – Building codes “Stick” Incentives – Tax credits “Carrot” Markets – Building performance labels Voluntary/Educational programs What metrics do you use to measure accomplishments? Energy Savings? Emissions Reductions? Costs? Baselines?
  4. 4. Current Research: Targeting Building CodesFocus on Commercial Building Codes Adoption of New CodesComplex No National Building Code State Codes Vary from No Code to Newest Code ASHRAE 90.1-2007 or 2009 IECC 90.1-
  5. 5. Commercial Building Codes As of September 14, 2010
  6. 6. Questions to AnswerWhy do states adopt new building energy codes? Energy savings? Economic reasoning? Environmental concerns?Are these energy code adoptions worth it? Energy savings? Economically viable? Over what time frame? Vary by building type? Environmentally beneficial?Does location matter? Climate/Region Energy Source and Costs Construction Costs
  7. 7. Metrics & Tools to answer these questions Metrics ToolsLife-Life-Cycle Costing Building for Environmental & Economic SustainabilityEnergy Savings (BEES) Product/component scaleLife-Life-Cycle Assessment BEES for Buildings System/building scale GIS Mapping
  8. 8. BEES for BuildingsBusiness Case for Sustainability Whole Building Integrated DesignCompare Energy Efficiency Alternatives (1) Life-cycle costing Life- First and Future Costs (2) Energy savings (3) Life-cycle assessment Life- Carbon footprintGIS Mapping
  9. 9. Building Prototypes12 Commercial Building Types Varying sizes and function Represents 29% of U.S. commercial building stock3 Energy Efficiency Alternatives ASHRAE 90.1-2004 - baseline 90.1- ASHRAE 90.1-2007 or “Low Energy Case” 90.1- Varying exterior envelope, lighting, and HVAC size228 Locations1, 10, 25, and 40-year study periods 10, 40-8,208 simulations
  10. 10. Energy savings (%) – 12 Building Types (10 Yr)90.1-2007 v 90.1-2004 Low Energy Case v. 90.1-2004
  11. 11. Energy savings (%) – 12 Building Types (10 Yr)90.1-2007 v 90.1-2004 Low Energy Case v. 90.1-2004
  12. 12. Energy savings map (%) –LEC for 3-Story Office Building 3-
  13. 13. Carbon Reduction (%) – 12 Building Types (10 Yr)90.1-2007 v 90.1-2004 Low Energy Case v. 90.1-2004
  14. 14. Carbon reduction map (%) –LEC for 3-Story Office Building 3-
  15. 15. Life- Life-cycle cost savings (%) – 12 Building Types (10 Yr)90.1-2007 v 90.1-2004 Low Energy Case v. 90.1-2004
  16. 16. Cost savings map (%) –LEC for 3-Story Office Building 3-
  17. 17. State Code AdoptionCompare adoption of ASHRAE 90.1-2007 from ASHRAE 90.1-2004 90.1- 90.1-Over all building types…Based on life-cycle cost savings? life- Top 20 – 30% adopted 90.1-2007 90.1- Bottom 20 – 46%Based on Energy Savings? Top 20 – 34% adopted 90.1-2007 90.1- Bottom 20 – 36%Based on Emissions Reductions? No correlation
  18. 18. SummaryEnergy efficient building designs are usually cost-effective over a cost-10+ year study periodLarge variation in benefits and costs across locations Climate, Code requirements, Energy costs, Construction costsStates are NOT adopting new building codes for economic,environmental, or energy-related reasons. energy-Gov. policies are necessary to improve nationwide energy efficiency Improve Education/Information Create Incentives Increase RequirementsEasy-to-Easy-to-understand metrics and tools are needed to inform andeducate the public and policymakers
