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• Discloses the additional effort and investment made by the developer to achieve a green and high performance building

• Reduce risk of green-washing

Environmental Protection (Green Mark)

• For all 3 systems, there is emphasis on public transport access and provision of greenery/landscaping to improve micro-climate comfort.

• 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

Criteria- WaterWater 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)g p ( g )

• But in Green Mark and GBI, emphasis on monitoring for leakage but not in LEED.

• 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

Criteria- Materials & ResourcesMaterials & 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 QualityIEQ(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 outsidecontrollability, daylight and views to outside

• Only LEED does not cover internal noise level
