Gunnar Hubbard- LEED vs Three Star Green Building Rating Systems

  1. 1. GREEN BUILDING RATING SYSTEMS: A COMPARISON OF LEED AND CHINA’S 3 STAR Presented by Gunnar Hubbard, AIA, LEED AP Fore Solutions Consultants for High Performance Green Buildings Portland, Maine USA www.fore-solutions.com March 24, 2009 1
  2. 2. Why Use Green Rating Systems? “Green Design” is a temporary term. It’s not an END, it’s a MEANS. . . a transition to a higher level of design – integrated design Rating Systems function as the “training wheels” for market transformation -to help support us in a fundamental shift of thinking Credit: US Green Building Council 2

  7. 7. Value of Green Building Rating Systems •  Indicates Efficiency and Effectiveness •  Demonstrates Environmental Commitment •  Promotes Market Transformation 7
  8. 8. Value of Green Building Rating Systems •  Formal Recognition •  Prevents “greenwashing” •  Third Party Verification/ Certification of Performance •  Tool for Governments 8
  9. 9. Value of Green Building Rating Systems •  Provide a consistent “meterstick” for evaluation •  Benchmark & Comparison Across Buildings •  Quantifiable goals & achievements •  Defines “Green/High Performance Buildings” 9

  23. 23. Three Star - CHINA (Ministry of Construction Green Building Evaluation Standards) “Purpose is to create a voluntary rating system that will encourage green development.” 23
  24. 24. Three Star •  Like LEED: Credit based •  Developers can choose which standards to pursue •  2 tracks: •  Residential Buildings, •  Public Buildings •  Rating happens after one year of occupancy •  Developed in 2006, Implemented 2007, First Buildings Received Rating in 2008. •  Run by MoC (now MOHURD) 24
  25. 25. Three Star •  Prerequisites = “Control Items” •  Credits = “General Items” •  Six thematic categories •  “Preference Items” are strategic, harder to reach targets •  Three levels of rating = One, Two and Three Stars 25
  26. 26. Three Star Green Building Rating Systems (as of early 2009) •  Three Star •  Many registered •  8 certified •  4 at Three Star level •  LEED •  161 registered •  12 certified 26

  32. 32. Three Star /LEED - WATER Water Efficiency (LEED) Water Saving and Water Resource Utilization (Three Star) • All LEED areas covered by Three Star • Three Star also includes credits for: •  Including water systems planning in early design •  Avoiding pipe leakage •  Monitoring safety of nontraditional water sources •  Efficient use of reclaimed water 32
  33. 33. Three Star /LEED - ENERGY Energy and Atmosphere (LEED) Energy Saving and Energy Utilization (Three Star) • LEED credits not in Three Star : •  Commissioning •  Refrigerant Management • Three Star credits not in LEED: •  No use of electric boiler/water heater for heating or cooling •  Standard for air tightness of windows 33
  34. 34. Three Star /LEED - MATERIALS Materials & Resources (LEED) Material Saving and Material Resource Utilization (Three Star) •  LEED credits not in Three Star • Collection and storage of recyclables • Rapidly renewable materials • Certified wood • Three Star credits not in LEED • Methods for increasing efficiency in concrete • Adopting an efficient structural system • Specific thresholds for harmful substances in materials • Encourages use of flexible partitions 34
  35. 35. Three Star /LEED – INDOOR ENVIRONMENT Indoor Environmental Quality (LEED) Quality of Indoor Environment (Three Star) •  LEED credits not in Three Star • Environmental Tobacco Smoke Control • Low-Emitting Materials • Thermal Comfort - Verification • Three Star credits not in LEED (partial) • Noise reduction measures • Air contaminant concentration standard • Max. temperature of room allowed under natural ventilation • Sound insulation requirements 35
  36. 36. Three Star /LEED – Operations Management Not included in LEED NC, closest to LEED EB:OM •  Goals: • Establish and implement energy savings, water savings, and other energy saving policies as well as green management policies • Relate improved performance to resource savings and economic benefits 36
  37. 37. WHO ADMINISTERS EACH RATING SYSTEM?   LEED –  LEED ACCREDITED PROFESSIONALS HELP ADMINISTER THE DESIGN AND CONSTRUCTION SUBMITTAL –  A “UNKNOWN” 3RD PARTY EVALUATES THE LEED DOCUMENTATION   3 STAR –  MOHURD IN EACH PROVINCE CERTIFIES FOR 1 STAR AND 2 STAR –  BEIJING OFFICE OF MOHURD ONLY GIVES 3 STAR. 37 37
  38. 38. Closing Discussion Point “The path to finding solutions is to bring together the finest, most passionate minds to work on the problem in a coordinated effort.” - Steve Chu, Secretary of Energy 38 38
