The Star 11 Dec 2008Sweden cleanest, S. Arabia dirtiest, Malaysia bottom 10: climate index
POZNAN (AFP) Sweden does the most of any country for tackling emissions of greenhouse gases, while Saudi Arabia does the least, according to a barometer published on Wednesday by watchdogs at the UN climate talks here.The groups categorised dangerous climate change as an increase in temperature beyond two degrees Celsius (3.6 Fahrenheit) over pre-industrial levels.
-
Sweden's fourth place was followed by Germany, France, India, Brazil, Britain and Denmark.
The bottom 10 were listed in descending order as Greece, Malaysia, Cyprus, Russia, Australia, Kazakhstan, Luxembourg, the United States, Canada and Saudi Arabia.
-
So how do we go about achieving a
GREEN BUILDING ?
-
A Green or Sustainable building is designed:
To save energy and resources, recycle materials and minimise the emission of toxic substances throughout its life cycle,
To harmonise with the local climate, traditions, culture and the surrounding environment, and
To be able to sustain and improve the quality of human life while maintaining the capacity of the ecosystem at the local and global levels
-
Green buildings have many benefits, such as better use of building resources, significant operational savings, and increased workplace productivity
Building green sends the right message about a company or organization - its well run, responsible, and committed to the future

Malaysian Buildings
Average BEI of office buildings in Malaysia is 200-250 Only a handful of buildings has BEI < 150
The benchmark buildings to-date are;
1. Securities Commission HQ (1999), BEI < 1202. LEO building (2004), BEI = 1003. PTMs ZEO building (2007), BEI = 50 (0)4. Energy Commission HQ (design), BEI = 80

BEI Calculations
BEI = (TBEC - CPEC - DCEC) / (GFAexcluding carpark - DCA -GLA*FVR)*(52/WOH)
-
BEI = (TBEC - CPEC - DCEC) / (GFAexcluding carpark - DCA -GLA*FVR)*(52/WOH)
Where; TBEC : Total Building Energy Consumption (kWh/year) CPEC : Carpark Energy Consumption (kWh/year) DCEC : Data Centre Energy Consumption (kWh/year) GFAexcluding carpark : Gross Floor Area exclusive of car park area (m2) DCA : Data Centre Area (m2) GLA : Gross Lettable Area (m2) FVR : Weighted Floor Vacancy Rate of GLA (%) 52 : Typical weekly operating hours of office buildings in
