Green Building Index

Negative Impact of Built Environment• Construction industry is a major consumer of non-renewable resources and a

massive producer of waste, and the operation of buildings is responsible for around half of the total CO2 emissions.

• 30-40% of natural resources were exploited by the building industry.• 50% of energy used for heating and cooling in buildings.• 40% of world consumption of materials converts to building environment.• 40% of waste sent to landfill.• 12% of water consumption in building industry.

Social Benefits• Enhance occupant comfort and

health• Heighten aesthetic qualities• Minimize strain on local

infrastructure• Improve overall quality of life

Economic Benefits• Reduce operating

costs• Create, expand and

shape markets for green product and services

• Improve occupant productivity

• Optimize life-cycle economic performance

Environmental Benefits• Enhance and protect

biodiversity and ecosystems

• Improve air and water quality

• Reduce waste streams

• Conserve and restore natural resources

General Benefits of Green Buildings

Source: Green Building US (2016)

Upfront investment in green building makes properties more valuable, with an average expected increase in value of 4%.

In January 2017, LEED reported that LEED-certified buildings have • 34% lower CO2 emissions• consume 25% less

energy• 11% less water • diverted more than 80

million tons of waste from landfills.Green buildings reduce day-to-day costs

year-over-year. LEED buildings report almost 20% lower maintenance costs than typical commercial buildings and green building retrofit projects typically decrease operation costs by 10% in just 1 year.

Between 2015 and 2018, LEED certified buildings are estimated to save• $1.2 billion in energy

savings• $149.5 million in water

savings• $715.2 million in

maintenance savings• $54.2 million in waste

What is Green Building Index (GBI)?Green Building Index (GBI) which is Malaysia’s first Comprehensive green rating tool was launched on May 21 2009 at Kuala Lumpur Convention Centre.

GBI is an environmental rating system for buildings developed by PAM (Pertubuhan Arkitek Malaysia / Malaysian Institute of Architects) and ACEM (the Association of Consulting Engineers Malaysia).

It is fundamentally derived from certain existing green rating tools, including:• Green Mark (Singapore)• Green Star System (Australia)

However, it had been extensively modified to cope with Malaysian tropical weather, environmental context, cultural and social needs.

Why Green

Buildings?

Green Buildings are designed to save energy and

resources, recycle materials and minimize the emission of toxic substances throughout

its life cycle.

Green buildings harmonize with the

local climate, traditions, culture and

the surrounding environment.

Green buildings are able to sustain and improve the

quality of human life whilst maintaining the capacity of the ecosystem at local and

global levels.

Green buildings make different use of resources, have significant operational savings and increases

workplace productivity.

Building green send the right message about a company or organization-that it is well run, responsible, and committed

to the future.

Energy Efficiency

Indoor Environment

Quality

Improve energy consumption by:I. Optimizing building orientation.II. Minimizing solar heat gain through building envelope.III. Harvesting natural lighting.IV. Adopting the best practices in building services

unclosing use of renewable energy, ensuring proper testing, commissioning and regular maintenance.

Good indoor air quality, acoustics, visual and thermal comfort can be achieved by:I. using low volatile organic compound materials.II. application of quality air filtration.III. proper control of air temperature , movement and

humidity.

Sustainable Site Planning

& Management

Material & Resources

Selected sites must with planned access to:I. Public transportationII. Community servicesIII. Open space and landscapingEnvironmentally sensitive areas are avoided and conserved through redevelopment of existing sites and brown fields.Proper construction management and storm water management is practiced. The strain on existing infrastructure capacity is reduced.

The use of environment-friendly materials sourced from sustainable sources and recycling is encouraged.Proper construction waste management with storage, collection and re-use of recyclables and construction formwork and waste is implemented.

Water Efficiency

Innovation Innovative design and initiatives that meet the objectives of the GBI.

Implementation of certain water efficiency methods:I. Rainwater harvestingII. Water recyclingIII. Water-saving fittings

What GBI is Created to

??

Promote integrated, whole building design.

Transform the built environment to

reduce the environmental

impact of development

Ensure new buildings remain relevant in the

future and existing buildings are refurbished and thereafter sustained

properly to remain relevant.

Define green building by establishing a

common language and standard of measurement.

Recognize and reward environmental

leadership.

Who Can Use The Green Building Index (GBI)?I. All member of Project Teams, Building Owners, Developers and other

interested parties such as Contractors, Government and Design and Build Contractors are encouraged to use GBI.

II. GBI is used to validate environmental initiatives of the design phase of new construction.

III. Encouraged the usage of GBI on such projects to assess and improve their environmental attributes.

IV. The usage of GBI (non residential) tool without formal certification by an independent accredited GBI certifier does not entitle the user to achieve Green Building Index rating.

V. Moreover, no fee is payable to Greenbuildingindex Sdn Bhd (GSB) under such use.

VI. However, a formal certification of the Green Building Index rating requires fee and formal process offered by (GSB).
