Green Building And Low Carbon Building in Malaysia

  1. 1. LOW CARBON GREEN BUILDING The Low Energy Office (LEO) & Green Energy Office (GEO) Building Experience Steve Anthony Lojuntin Principal Energy Engineer Energy, Manufacturing, Green Building/Township & Green ICT Division (EMBIT) Malaysian Green Technology Corporation Tel / SMS :+6019-2829102 Email: asetip@damansara.net GEO BuildingLEO Building
  2. 2. RELATION BETWEEN CLIMATE CHANGE,GHG AND GREEN TECHNOLOGY PROBLEM! SOLUTION! CLIMATE CHANGE GREEN IS THE PROBLEM TECHNOLOGY AND [MAINLY CAUSED GREEN LIVING IS BY GREEN HOUSE THE SOLUTION GASES (GHG)] GHG : Carbon dioxide, Methane, NOx, SOx, CFC, etc
  3. 3. 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 improved environment for all forms of life It conserves the uses of energy and natural resources; and It promotes the use of renewable resources.
  4. 4. 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.
  5. 5. Brief about Green Building Green Technology Green Habits / Involved Thinking - Energy - Awareness / Responsibility - Indoor Environment - Procurement - Water Management - Operation & Maintenance - Material used - Recycling - Site construction - Green / Sustainable / Low Carbon Buildings
  6. 6. Common Green Building Criteria
  7. 7. General Green Building System Alternative under Conventional Green Building System development LOW CARBON BUILDING PRIVATE INITIATIVE (Malaysia) 1. Energy 2. Water 3. Indoor environme nt 4. Waste Gov. Initiatives -CASBuild for BCIS (GreenTech Malaysia – consultancy projects) - GreenPASS (CIDB)
  8. 8. Good New to the Industry Low Carbon Building System
  9. 9. Carbon emission in a life cycle of a building Pre - Normally addressed by , D li ne n / Design De esig vel n & most Green Building ec litio ion D o at op Tools me em ner D ge nt [Embodied CO2 footprint] re Building Lifecycle Use, Management & Maintenance [Higher CO2 footprint] FACT! Most of the CO2e emission is during the operation phase !! Only Low Carbon Building Assessment System address this issue !!!
  10. 10. Brief aboutLow 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.
  11. 11. Brief aboutLow 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 $$$/CO2 reduction cost). • Global trend - Relevant and gain popularity at international level.
  12. 12. Why Low Carbon Building System is Affordable ?Cheaper way The longer the way = $$$$$
  13. 13. Carbon Exist in Most ofthe Green Building Criteria
  14. 14. WHERE DOES THE CARBON COME FROM?
  15. 15. Chances to reduce carbon emission Building sector has the higher chances to reduce carbon emission in a township Sumber: Laporan IPCC
  16. 16. WHY LOW CARBON GREENBUILDING 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
  17. 17. Green Technology / application inBuildings 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 Environment related 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
