The document describes the Green Building Index (GBI), Malaysia's first comprehensive rating system for evaluating the environmental design and performance of buildings. The GBI measures energy efficiency, indoor environmental quality, sustainable site planning/management, materials/resources, water efficiency, and innovation. It aims to promote sustainable and green building practices in Malaysia by establishing standards, recognizing environmental leadership, and transforming the built environment to reduce impacts. The GBI rating tool can be used by project teams, owners, developers and other parties to assess and improve the environmental attributes of new buildings.

2. INTRODUCTION

3. WHAT?
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).
Its develop specifically for the Malaysian Tropical Weather, environmental
and environmental context, cultural and social needs.
Malaysia’s first comprehensive rating system for evaluating the
environmental design and performance of Malaysian buildings based on
 Energy Efficiency,
 Indoor Environment Quality,
 Sustainable Site Planning & Management
 Materials & Resources
 Water Efficiency
 Innovation.

4. • Improve energy consumption by
• – building orientation
ENERGY • -minimizing solar heat gain through the building envelope
EFFICIENCY (EE) • -harvesting natural light
• -use renewable energy
• Achieve good quality performance of indoor air quality,
INDOOR acoustic, visual and thermal comfort.
ENVIRONMENTAL • Use of volatile organic compound materials
• Application of quality air filtration
QUALITY (EQ) • Proper control of air temperature, movement and humidity
SUSTAINABLE
SITE PLANNING • Pr oper site with planned acces to public transportation,
community services, open spaces and landscaping.
AND • Implementing proper construction management, storm
MANAGEMENT water management

5. • Promote the use of eco friendly materials sourced from
sustainable sources and recycling.
MATERIALS AND • Implement proper construction waste management with –
RESOURCES (MR) storage-collection
• Reuse of recycables and construction formwork and waste.
• Rainwater harvesting
WATER EFFICIENCY • Water recycling
(WE) • Water saving fittings
INNOVATION (IN) • Innovative design that meets the objectives of the GBI.

6. GBI IS CREATED TO?
• Define green buildings by establishing a common language and
standard of
measurement;
• Promote integrated, whole-building design;
• Recognise and reward environmental leadership;
• Transform the built environment to reduce it’s environmental impact;
and
• Ensure new buildings remain relevant in the future and existing
buildings are
refurbished and upgraded properly to remain relevant.
 The developers will be able to plan more sustainable and green
projects.
 Allow us to undertake development in a more environmental –friendly
way
 To get better siting, design, construction, operation, maintenance and
removal

8. WHO CAN USE THE GBI?
All members of Project Teams, Building owners, Developers and other
interested
parties (including Contractors, Government and Design & Build
Contractors)
 To validate environmental initiatives at the design phase of new
construction
 encouraged on all such projects to assess and improve their
environmental attributes.

12. •For this residential new construction, it includes
linked houses, apartments, condominiums,
townhouses, semi-detached and bungalow.
•It more emphasis on sustainable site planning and
management, followed by energy efficiency.
GBI RATING TOOL •Will reduce the negatice impact to the
environment
•And create better and safe place for the
community as a whole.
