WHAT IS THE GREEN BUILDING INDEX?
The Green Building Index (GBI) is Malaysia’s industry recognised green rating tool for buildings to
promote sustainability in the built environment and raise awareness among Developers, Architects,
Engineers, Planners, Designers, Contractors and the Public about environmental issues and ourresponsibility to the future generations.
The GBI rating tool provides an opportunity for developers and building owners to design and construct
green, sustainable buildings that can provide energy savings, water savings, a healthier indoor
environment, better connectivity to public transport and the adoption of recycling and greenery for their
projects and reduce our impact on the environment.
GBI is developed specifically for the Malaysian-tropical climate, environmental and developmental
context, cultural and social needs and is created to:
• Define green buildings by establishing a common language and standard of measurement;
• Promote integrated, whole-building designs that provides a better environment for all;
• Recognise and reward environmental leadership;
• Transform the built environment to reduce its negative environmental impact; and
• Ensure new buildings remain relevant in the future and existing buildings are refurbishedand upgraded to improve the overall quality of our building stock.

WHAT IS A GREEN BUILDING?
A Green building focuses on increasing the efficiency of resource use – energy, water, and materials –
while reducing building impact on human health and the environment during the building’s lifecycle,through better sitting, design, construction, operation, maintenance, and removal. Green Buildings
should be designed and operated to reduce the overall impact of the built environment on itssurroundings.

WHY GREEN BUILDINGS?
A Green building focuses on increasing the efficiency of resource use – energy, water, and materials –
while reducing building impact on human health and the environment during the building’s lifecycle,through better sitting, design, construction, operation, maintenance, and removal. Green Buildings
should be designed and operated to reduce the overall impact of the built environment on itssurroundings.
Green buildings are designed to save energyand resources, recycle materials and
minimise the emission of toxic substancesthroughout its life cycle.
Green buildings harmonise with the localclimate, traditions, culture and the
surrounding environment.
Green buildings are able to sustain andimprove the quality of human life whilst
maintaining the capacity of the ecosystem atlocal and global levels.
Green buildings make efficient use of resources, have significant operational
savings and increases workplaceproductivity.
Building green sends the right messageabout a company or organisation – that it is
well run, responsible, and committed to thefuture.
THE GBI ASSESSMENT PROCESS

STAGE 1Application & Registration
Complete and submit the GBI
Application Form with the
Applicant’s contact details, projectinformation and supporting
documents to Greenbuildingindex
Sdn Bhd (GSB). The Registration
Fee will be set depending on the
size of the project. Upon payment
of the fees, a GBI registration
number will be given and the GBI
Terms and Conditions will be
signed between the Applicant and
GSB. A GBI Certifier will then be
appointed for the project.

STAGE 2Design Assessment (DA)
When the Applicant is ready he
may then submit the project for
GBI Design Assessment (DA)either directly or through an
appointed GBI Facilitator.
Submission should be done when
all key criteria of the design are
finalised and preferably before the
commencement of construction so
as to enable the project to be
monitored and assessed in its
entirety. The GBI Certifier will
then undertake the Design
Assessment for GSB. This may
involve a presentation by the
Applicant and their Project Design
Team or by the GBI Facilitator.The GBI Certifier will upon
completion, table the assessment
report to the GBIAP to register
and award the certification. The
provisional GBI Design
Assessment certification will then
be issued with the accompanying
GBI score sheet to show the
scores achieved.

STAGE 3Completion & Verification
Assessment (CVA)
Upon completion of the project,
the Applicant should submit forthe Completion and Verification
Assessment (CVA). This is to be
done within 12 months after the
completion of the building or
when the building becomes 50
percent occupied, whichever is the
earlier. The final GBI award will be
issued by the GBIAP upon
completion of this CVA
assessment. Buildings are
awarded GBI - Platinum, Gold,
Silver or Certified ratings
depending on the scores
achieved. Buildings will have to bere-assessed every three years in
order to maintain their GBI rating
to ensure that the buildings are
well-maintained.

THE GBI RATING SYSTEM
8/6/2019 What is the Green Building Index
http://slidepdf.com/reader/full/what-is-the-green-building-index 9/11
BUILDINGS WILL BE AWARDED THE GBI RATING BASED ON6 KEY CRITERIA:
1 Energy Efficiency (EE)
2 Indoor Environmental Quality (EQ)
3 Sustainable Site Planning & Management (SM)
4 Material and Resources (MR)
5 Water Efficiency (WE)
6 Innovation (IN)
1) Energy Efficiency (EE)
Improve energy consumption by optimising building orientation, minimizing solar heat gain through the buildingenvelope, harvesting natural lighting, adopting the best practices in building services including use of renewable
energy, and ensuring proper testing, commissioning and regular maintenance.
2) Indoor Environment Quality (EQ)Achieve good quality performance in indoor air quality, acoustics, visual and thermal comfort. These will involve
the use of low volatile organic compound materials, application of quality air filtration, proper control of air
temperature, movement and humidity.
3) Sustainable Site Planning & Management (SM)Selecting appropriate sites with planned access to public transportation, community services, open spaces and
landscaping. Avoiding and conserving environmentally sensitive areas through the redevelopment of existing sites
and brownfields. Implementing proper construction management, storm water management and reducing the
strain on existing infrastructure capacity.
4) Materials & Resources (MR)Promote the use of environment-friendly materials sourced from sustainable sources and recycling. Implement
proper construction waste management with storage, collection and re-use of recyclables and construction
formwork and waste.
5) Water Efficiency (WE)Rainwater harvesting, water recycling and water-saving fittings.
6) Innovation (IN)Innovative design and initiatives that meet the objectives of the GBI.
Achieving points in these targeted areas will mean that the building will likely be more environment-friendly than
those that do not address the issues. Under the GBI assessment framework, points will also be awarded forachieving and incorporating environment-friendly features which are above current industry practice.
THE GBI RATING TOOLS

NON-RESIDENTIAL
The GBI Non-Residential Rating tool evaluates thesustainable aspects of buildings that are
commercial, institutional and industrial in nature.
This includes factories, offices, hospitals,universities, colleges, hotels and shopping
complexes.
Of the six criteria that make up the GBI rating,
emphasis is placed on energy efficiency and indoor
environmental quality as these have the greatest
impact in the areas of energy use and well-being of
the occupants and users of the building.
By improving on the efficiency of active (mechanical
and electrical) systems as well as incorporating
good passive designs together with proper
sustainable maintenance regimes, significantreductions in consumed energy can be realised. This
can lead to a reduced carbon footprint and also
offers long-term savings for the building owners.
