LOW CARBON BUILDING
INITIATIVES IN MALAYSIA Affordable and practical way to reduce carbon in building sector
GLOBAL PROBLEM - CLIMATE CHANGE,
GHG
PROBLEM!
CLIMATE CHANGE IS THE PROBLEM [MAINLY CAUSED BY GREEN HOUSE
GASES (GHG)]
SOLUTION!
GREEN TECHNOLOGY AND
GREEN LIVING IS THE SOLUTION
GHG : Carbon dioxide, Methane, NOx, SOx, CFC, etc
Low Carbon Development in Malaysia
2009 : COP 15 in Copenhagen
2015 : COP 21 in Paris “… Malaysia intends to reduce its greenhouse gas (GHG) emissions intensity of GDP by 45% by 2030 relative to the emissions intensity of GDP in 2005.”
2010 : Green Technology Policy to support
green and low carbon development
Green technology is the development and application of products,
equipment, and systems used to conserve the natural environment and
resources, which minimises and reduces the negative impact of human
activities
Minimises the degradation of the environment.
It has zero or low green house (GHG) emission.
It safe for use and promotes healthy and improved
environment for all forms of life
It conserves the uses of energy and natural
resources; and
It promotes the use of renewable resources.

Low Carbon Development in Malaysia
More People Living in Urban Areas/Cities
Population Malaysia 18 million (1990) to 27.6 million (2010) - increase by 53% (Source: Census Data, 2010) Urbanization Rate • 27% in 1960, 42% in 1990, 54% in 1994, 61.8% (2000) for Malaysia, 65.4% (2000) for West Malaysia • Expected to grow to 75% by 2020 (Source: RFN 2001)
Energy • Energy Consumption – 61,279 metric tons (2005) (40% transportation & 40% industrial) • Energy Produced – 99,917 metric tons (2005) • 2006 – CO2 emission – 187 million tons 7.2 metric tons/person • 2004 – 5.9 metric tons/World 4.4 metric tons/person Info from Malaysia Inst. Of

• Low Carbon Building is similar to the conventional
green building system which promotes uses of green
technology and green habits to reduce the degradation of
the environment.
• The low carbon building use Carbon as metric for
quantitative references to assess the actual
environment impact and not based on points
collected.
• A performance based: Does not address and assess on
how the building being designed. Only measure and
assess the actual carbon reduction.
What are the Low Carbon buildings
• Straight forward, flexible, transparent, easy to
implement, consistance, easy to monitor since
based on actual performance. Measurable,
recordable, comparable, justifiable, can be
monitor and easy to proof.
• Cheaper and affordable since it is straight
forward and focus only the relevant criteria that
have high impact (lower $$$/CO2 reduction cost).
• Global trend - Relevant and gain popularity at
international level.

• A voluntary & industry driven initiatives by SEDA. • The assessment using UNEP-SBCI Common Carbon Metric, MS 1525 & CIDB’s CIS20-
GreenPASS.
To support the low carbon cities development.
To provide national consistency and a common language around the definition of low carbon building.
To provide systematic assessment to encourage energy efficiency in building implementation.
As platform for building owners to declare the performance of the buildings.
To support government initiatives (RMK-11, LCCF, NEEAP, Energy Audit Program).
To provide a basis for ongoing assessment and evaluation of low carbon building.
As alternative platform towards achieving Green Building Certification (MyCREST, GBI, etc.)
To facilitate local authorities to develop Common Carbon Metric for various building typologies.

Common Question by the Industry
Is the Low Carbon Building / Energy
Efficient Building a green building?
Answer = YES ! As a basic green building
Based on facts;
Green Technology Policy Definition.
Sustainable energy is part of basic green component.
Most global green buildings movement uses climate change
as key reason for going green (key contributor to climate change
is carbon emission that mostly by product of energy consumption.
Proof in Malaysia : The EE building (LEO & GEO Building)
achieved Green Building Certification (GBI)
