1 LEED, Green Mark, Green Building Index By: Regina Ng, IEN Consultants Presentation for Veritas 8 October 2009 Outline of Presentation Background Assessment Categories Scoring Certification Level Criteria 1

2 The Big Picture: Energy Impact per Person Please guess the top energy consumptions? Source: Sustainable Buildings without the hot air by David MacKay, Cambridge University, 2009 Benefits of Labelling Buildings Provides an objective framework to assess buildings on the same platform Differentiate one building from another in the market Inform the tenants and public on the environmental benefits of the building Discloses the additional effort and investment made by the developer to achieve a green and high performance building Reduce risk of green-washing 2

3 Background LEED Green Mark GBI Launched by US Green Building Council in 1998 Private driven Voluntary rating system but in some states, they have rating of public buildings compulsory Launched by Building Construction Authority (BCA) in 2005 Public driven with industry support Mandatory rating system Launched by PAM and ACEM in 2009 Private driven Voluntary rating system Suite of Schemes Building Life Cycle DESIGN CONSTRUCTION OPERATIONS LEED Homes Neighbourhood Development (in pilot) Commercial Interiors Core and Shell New Construction Schools, Healthcare and Retail Green Mark Residential Non residential Office Interior Landed Houses Infrastructure Existing Buildings Operations & Maintenance Existing Buildings Green Building Index Residential Non residential 3

For LEED and GBI, emphasis on site selection to minimise automobile emissions For LEED and GBI, most criteria overlap except for Workers Site Amenities for GBI 6

7 Criteria- Water Water Efficiency (LEED) Water Efficiency(GBI) Water Efficiency (Green Mark) For LEED and GBI, more performance based approach towards total volume of potable water reduced For Green Mark, more feature based. More emphasis on water conservation in Green Mark, also including non-process water (cooling tower) But in Green Mark and GBI, emphasis on monitoring for leakage but not in LEED. Criteria- Energy Energy & Atmosphere (LEED) Energy & Efficiency(GBI) Energy Efficiency (Green Mark) Cumulative percentile 100% 90% 80% 70% 60% Malaysia 50% (41 office 40% buildings) 30% Singapore 20% (95 office 10% buildings) 0% Energy Efficiency Index (kwh/m2/year) For LEED and GBI, looks at overall energy reduction as a indicator and award points for it Green Mark focuses more on reducing energy consumption for the various systems In Green Mark, there are pre-requisites of achieving certain energy reduction to obtain the higher rating GBI places more emphasis on commissioning and maintenance All 3 systems now require measurement & verification of energy performance after occupancy 7

8 Criteria- Materials & Resources Materials & resources (LEED) Materials & Resources(GBI) Environmental Protection (Green Mark) All 3 systems look into reducing waste during construction and reducing waste after occupancy GBI and Green Mark looks into sustainable construction methods explicitly but not LEED. LEED and GBI have most of the criteria overlapping each other There is focus on certified wood and regional materials for LEED and GBI Criteria- Indoor Environmental Quality IEQ(LEED) IEQ(GBI) IEQ (Green Mark) All 3 systems look into reducing indoor air pollutants at source Greater emphasis on IEQ both during construction and after occupancy by LEED and GBI LEED and GBI also recognizes the value of individual controllability, daylight and views to outside Only LEED does not cover internal noise level 8
