  • 1. Relevant ASHRAE Standards For Energy Efficiency in Buildings Prof. Walid Chakroun, DRC, RAL ASHRAE Engineering the World We Live In Roundtable on Ozone- and Climate Friendly Technologies in RAC, 10 May 2011
  • 2. Today’s building designs mortgage our energy future.
  • 3. Why Are Buildings So Important?• World total energy consumption is expected 40% of U.S. Primary Energy Consumption to increase as high as 50 percent in less than a decade.• Buildings are responsible for 38% of total energy use – that figure increases to up to 70% in Source: 2007 Buildings Energy Data Book. Tables 1.1.3, 1.2.3, 1.3.3 some countries. 3
  • 4. Fastest Growing Energy Sector 45 Industrial 40 Transportation Buildings Total 35 30 25 Quads 20 15 10 5 0 1980 1985 1990 1995 2000 2005 Year Source: EIA Annual Energy Review, Tables 2.1b-2.1f., June 2007Buildings sector energy consumption growing faster than any other sector.
  • 5. Building Energy Efficiency“…is the single most important opportunity for reducing greenhouse gas emissions” “…is the “fastest-growing (2007-2008 ASHRAE President Kent Peterson) success story of the last 50 years” (American Council for an Energy Efficient Economy)
  • 6. What is ASHRAE Doing to Help
  • 7. Standard 90.1 • Standard 90.1-2010 was published last Fall • Celebrating 35th anniversary of publication of Standard 90.1 • Developed in response to U.S. energy crisis of 1970s • ry
  • 8. Standard 90.1• 2007 standard is the reference standard for the International Energy Conservation Code• Adopted by National Fire Protection Association• Adopted by many countries around the globe
  • 9. Standard 90.1• Provides minimum requirements for the energy- efficient design of buildings except low-rise residential buildings• Covers – New buildings and their systems – Additions – alterations
  • 10. Standard 90.1 Sections• Section 1 – purpose• Section 2 – scope• Section 3 – definitions, abbreviations and acronyms• Section 4 – administration and enforcement• Section 5 – building envelope• Section 6 – heating, ventilating and air conditioning
  • 11. Standard 90.1 Sections• Section 7 – service water heating• Section 8 – power• Section 9 – lighting• Section 10 – other equipment• Section 11 – energy cost budget method• Section 12 – normative references
  • 12. Standard 90.2The purpose of this standard is toprovide minimum requirements for theenergy-efficient design of residentialbuildings. 12
  • 13. Standard 90.2– This standard provides minimum energy-efficiency requirements for the design and construction of new residential dwelling unitsIt covers:– New residential buildings and their systems– Additions 13
  • 14. Green Building Standard • Published in January 2010 • Serves as benchmark for sustainable green buildings – does not apply to all buildings • Addresses energy, impact on the atmosphere, sustainable sites, water use, materials and resources and IEQ
  • 15. What is Standard 189.1?• ANSI standard developed in model code language• Provides minimum requirements for high-performance, green buildings• Applies to all buildings intended as high performance except low-rise residential buildings (same as ASHRAE/IESNA Std 90.1)• Not a design guide, not a rating system• Jurisdictional compliance option to the International Green Construction Code published by the International Code Council and cooperating sponsors, American Institute of Architects and ASTM International
  • 16. Standard 189.1Building Blocks
  • 17. Compliance PathsMandatory + Prescriptive Path (simple option, very few calculations)Mandatory + Performance Path (more options, but more effort)
  • 18. Standard 189.1 Topic AreasSS Sustainable SitesWE Water Use EfficiencyEE Energy EfficiencyIEQ Indoor Environmental Quality Building’s Impact on the Atmosphere, Materials &MR ResourcesCO Construction and Operations Plans
  • 19. In a global marketplace, the objective of the standards development process must be a single, internationally recognized, technically valid standard that allows products to be distributed for commerce worldwide with minimal change or modification.One Global Standard Accepted by All
  • 20. What’s Your Building EQ?• In Operation Pilot completed in June 2010• 23 buildings from 10 owners/operators• 17 Provisional Assessors• Assessments include: - Building characteristics - Building Energy Quotient - IEQ Assessment• As Designed rating was also followed in second half of 2010
  • 21. Building Energy Labels Provide. . . • Information on the potential and measured energy use of buildings • Feedback to building owners and operators on how their building is performing • Insight into the value and potential of investments for long-term energy costs • Opportunity to differentiate buildings in a technically sound and consistent manner
  • 22. Advanced Energy Guidance • Over 250,000 guides in circulation – 80 percent US, 8 percent Canada, 12 percent ROW • DOE recently approved AEDG 50% Funding – First Guide to be Small-Med Office • Available for free download
