  3. 3. 11 Dec 2012 ASHRAE Illinois Chapter Background
  4. 4. 11 Dec 2012 ASHRAE Illinois ChapterLabeling = Energy Certification • Description of energy use characteristics • Information for prospective users concerning efficiency • Options for improvement L. Pérez-Lombard, et al. 2009. Energy and Buildings 41: 272-278.
  5. 5. 11 Dec 2012 ASHRAE Illinois ChapterObjectives/Benefits of Labeling• Promote energy efficiency in real estate market• Identify buildings with good performance for potential tenants/buyers• Identify energy efficiency measures• Support regulation of building efficiency• Add to building performance database
  6. 6. 11 Dec 2012 ASHRAE Illinois ChapterWhy is ASHRAE getting involved?• Technical capability• Experience as a consensus standards developer• Growing emphasis on building performance• Energy certification is being implemented worldwide— ASHRAE’s global influence supports consistent standards
  7. 7. 11 Dec 2012 ASHRAE Illinois ChapterOther Building Rating Efforts• International - EU, Singapore, Canada…• U.S.: • EPA ENERGY STAR • DOE asset rating (under development) • USGBC LEED • GBI Green Globes – Sustainability rating • BOMA 360 – Energy is one of six O&M-focused criteria • State disclosure programs– California, New York, DC…

  10. 10. 11 Dec 2012 ASHRAE Illinois ChapterWhy Should Professionals & Owners Care?• Professionals • An additional service for consulting firms and others • Required certifications demonstrate competency• Owners • Benchmarking • Participation enhances a company’s image reputation • Economic benefit of improving design and operation • Potential for mandatory labeling and related requirements in future
  11. 11. 11 Dec 2012 ASHRAE Illinois ChapterKey Issues• Modeled or measured (new/existing)• Performance index• Energy labeling scale• Energy modeling/measurement method• Information gathering requirements (what, by whom)• Identification of energy efficiency measures• Communication: (label, dashboard, certificate, workbook)• Implementation: voluntary vs. mandatory
  12. 12. 11 Dec 2012 ASHRAE Illinois Chapter ASHRAE’s Labeling Program - Overview
  13. 13. 11 Dec 2012 ASHRAE Illinois Chapter“Building Energy Quotient” (bEQ)• “As Designed” rating • New or existing building • Based on components specified in design • Rates quality of building design • Based on energy model by certified modeler (BEMP)• “In Operation” rating • Existing buildings • Based on measured energy use • Rates combined effect of design and operation • Requires 12-18 months of operation for new buildings • Includes ASHRAE Level 1 audit by certified assessor (BEAP)
  14. 14. 11 Dec 2012 ASHRAE Illinois ChapterPerformance Index• What is measured? • Site energy • Source energy • On-site renewables • Emissions• What is the reference case? • Occupancy • Climate zone • ???
  15. 15. 11 Dec 2012 ASHRAE Illinois ChapterASHRAE’s Index• Normalized Source Energy Use Intensity • Modeled (As Designed) or measured (In Operation) energy per unit of area • Represent as % of modeled or calculated reference value
  16. 16. 11 Dec 2012 ASHRAE Illinois ChapterAs Designed bEQ• EUIAs-Built • Source energy use of actual building design computed using standard occupancy and operational schedules • Site-source conversion based on typical conversion factors• EUIStandard • Representative middle-of-distribution performance EUI As − Built = bEQAs Designed ⋅100 EUI Standard
  17. 17. 11 Dec 2012 ASHRAE Illinois ChapterIn Operation bEQ• EUIMeasured • Measured energy use intensity• EUIMedian • Median measured energy use for similar type, climate EUI Measured = bEQIn Operation ⋅100 EUI Median
  18. 18. 11 Dec 2012 ASHRAE Illinois ChapterAs Designed & In Operation RatingCoordination?• Ideally, could compare asset and operational rating• However... • Modeling for asset rating based on standardized assumptions • In Operation rating reflects behavior of real occupants, may included loads not modeled in asset rating• Modeling rules need to achieve ~ median EUI for real buildings
  19. 19. 11 Dec 2012 ASHRAE Illinois Chapter Rating Scale Approaches Statistical Technical PotentialCompare value to mean of actual distribution Compare to what is possible, practical, typical as defined by codes Technical potential scales can rate performance that falls outside the current distribution, like net zero or net positive buildings

  47. 47. 11 Dec 2012 ASHRAE Illinois ChapterLEED (USGBC)• 110 point scale covering site, water, energy/atmosphere, materials/resources, IEQ, innovation/design process• 40 points for minimum “certified” rating, 50/60/80 for silver/gold/platinum• New Construction • Prerequisite 10% better than ASHRAE 90.1-2007 • Energy efficiency: 1 – 19 points for exceeding ASHRAE 90.1 by 12 to 48% • “technical potential” basis• Existing Buildings • Prerequisite 69 ENERGY STAR equivalent • Energy efficiency 1 – 18 points for ENERGY STAR equivalent 71 – 95 • “statistical” basis• bEQ could serve as a consistent energy rating method for both
  48. 48. 11 Dec 2012 ASHRAE Illinois ChapterUS Department of Energy Asset Rating• “Asset” rating = as-designed• In development - source energy calculated from national conversion factors like Portfolio Manager• Technical performance scale• Asset rating tool • User enters data, does not perform simulation • Multiple levels of input detail • Simulation and report generated without user intervention• Free/cheap – two levels of rating• Too early to judge impact on bEQ – early discussions about complementary relationship…we’ll see• Soliciting partners for pilot, ASHRAE is enrolled

  53. 53. 11 Dec 2012 ASHRAE Illinois ChapterIn Operation Pilot• Rated 21high profile buildings around the U.S.–from some of the largest private and public landlords• Building characteristics • Mostly office buildings, pre-1900 to post-2005, median 1985 • <100,000 sf to >1,000,000 sf • DOE climate zones 2 – 6 • Most ENERGY STAR rated• Provisional assessors (pre-BEAP)
  54. 54. 11 Dec 2012 ASHRAE Illinois ChapterMajor Participants
  55. 55. 11 Dec 2012 ASHRAE Illinois ChapterIn Operation Pilot Findings• Most good buildings will get a grade of “B” – some better, some worse (Pilot: 5 A-, 14 B, 2 C using adjusted scale)• Energy savings opportunities seen as most beneficial aspect of program• Occupant surveys were not accepted in the marketplace• Typical professional hours 35-40 for ratings• Building personnel need to be engaged
  56. 56. 11 Dec 2012 ASHRAE Illinois ChapterIssues from In Operation Rating Pilot• Need to maintain differentiation from ENERGY STAR and other alternative programs to secure marketplace niche• Costs for obtaining labels• Extending rating normalization to additional building types• Reaction of owners to less than stellar ratings? • Scale was adjusted based on pilot results • Nine of twenty-one pilot buildings requested labels: 4 A- rated buildings and 5 B rated buildings
  57. 57. 11 Dec 2012 ASHRAE Illinois Chapter As Designed Rating Pilot
  58. 58. 11 Dec 2012 ASHRAE Illinois ChapterIssues/Approach• Compare model of actual building with reference building • Modeling rules for schedules, plug loads, etc.? • What is the baseline? • What is the significance of modeler effect?• To maximize ability to compare with operational rating (CBECS-based for US) use DOE Benchmark Building models for small, medium, large office buildings with ASHRAE Standard 90.1-1989 equipment efficiencies• To investigate modeler effect, each pilot building will be modeled by 2-3 BEMPs
