Synopsis

GBI is developed specifically for the Malaysian-tropical climate, environment and development context, cultural and social needs.

Apart from being tailored to reflect the hot and humid climatic requirements, it also addresses notoriously neglected issues such as commissioning, retro-commissioning, post commissioning and sustainable maintenance.

It includes the benchmarking of enhanced energy efficiency performance by means of Building Energy Intensity (BEI).

What is Green/Sustainability?

“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Brundtland Commission report of 1987

What are Green or Sustainable buildings ?

1. Green buildings are designed to save energy and resources, recycle materials and minimise the emission of toxic substances throughout its life cycle,

2. They harmonise with the local climate, traditions, culture and the surrounding environment, and

3. 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

4. Green buildings have many benefits, such as better use of building resources, significant operational savings, and increased workplace productivity

5. Building green sends the right message about a company or organization – that it is well run, responsible, and committed to the future

Why a MALAYSIAN Green Rating Tool ?

• Most available tools are for temperate climates. Apart

from Green Mark this will be the FIRST TROPICAL

GREEN TOOL

• Harmonise with the LOCAL PRACTICES,

CULTURE and the local environment, and

• Reflect LOCAL PRIORITIES, availability of LOCAL

RESOURCES and LOCAL CHALLENGES and yet

• Incorporate HIGH PRIORITY GLOBAL

CHALLENGES whilst accommodating the capacity

of the ecosystem at local levels

Owners of buildings awarded the Green Building Index (GBI)

certificate be given tax exemption equivalent to 100% of the

additional capital expenditure incurred to obtain the GBI

certificate which can be set-off against 100% of the

statutory income for each year of assessment. The incentive

is applicable for new buildings and upgrading of existing

buildings. The incentive is given only for the first GBI

certificate issued in respect of the building.
