Green Building And Low Carbon Building in Malaysia
Paper presented in CIDB GreenBUILD International Conference in 2011. About the development of Low Carbon Green Building in Malaysia and its significant to have the industry and government that looking a simple, straight forward, practical and affordable solution to achieve low carbon green buildings, towards supporting Malaysia\'s target to reduce 40% carbon imission intensity per GDP in 2020 over the 2005 baseline

RELATION BETWEEN CLIMATE CHANGE, GHG AND GREEN TECHNOLOGY
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
Green Technology?
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 improvedenvironment for all forms of life
� It conserves the uses of energy and natural resources; and
� It promotes the use of renewable resources.
Brief about Green Building
What are Green or Sustainable buildings ?
• Save energy and resources, recycle materials and minimise the emission of toxic substances throughout its life cycle,
• Harmonise with the local climate, traditions, culture and the surrounding environment, and
• Able to sustain and improve the quality of human life whilst maintaining the capacity of the ecosystem at local and global levels.
• Savings and increase workplace productivity.
Brief about Green Building
Green / Sustainable / Low Carbon Buildings
Green Technology Involved- Energy - Indoor Environment- Water Management- Material used- Site construction-
FACT! Most of the CO2e emission is during the operation phase !!
Only Low Carbon Building Assessment System address this issue !!!
Carbon emission in a life cycle of a building
Brief about Low Carbon Building
What are the Low Carbon buildings ?
• 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.
• Use Carbon as metric for references to achieve the actual environment impact and not based on points collected.
• Use UNEP SBCI Common Carbon Metric.
Brief about Low Carbon Building
What are the Low Carbon buildings ?
• Straight forward, 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 $$$/CO2 reduction cost).• Global trend - Relevant and gain popularity at international level.
Why Low Carbon Building System is Affordable ?
The longer the way = $$$$$
Cheaper way
Carbon Exist in Most of the Green Building Criteria
WHERE DOES THE CARBON COME FROM?
Chances to reduce carbon emission
Sumber: Laporan IPCC
Building sector has the higher chances to reduce carbon emission in a township
WHY LOW CARBON GREEN BUILDING IS SUPERIOR?
� Easy to evaluate the actual performance through its life cycle.
� Straight forward and transparent of accounting emissions through carbon footprint.
� Has potential for carbon trading purposes (if applicable).
� Complement to the existing conventional GB system by helping to narrow the gap and maturing the green building industry.
� Supporting government efforts for reaching national climate reduction target for 2020
� Provide flexibility for designers to achieve the design target.
� Economical and affordable by all stakeholders
Green Technology / application in Buildings to reduce carbon foot print
-The green technology in building is mostly refer to the technology and applications that has impact to the Energy and Environmentrelated to building services
a) Design : Energy Efficiency, Renewable Energy & Water Management.
b) Office appliances
c) Operation: Energy management in the O&M.
d) Renovation / retrofits
e) Other - Paper and water recycling
- Indoor air quality.
- Solid waste management / separation
f) End users awareness
Relation between use of energy and the environment
Kawasan 2007Semenanjung Malaysia 0.684 kg CO2 / kwj
Sarawak 0.873 kg CO2 / kwj
Kawasan Barat Sabah 0.807 kg CO2 / kwj
