ABSTRACT
According to a study by the United Nation Environment Protection - Sustainable Building Climate Initiatives (UNEP -SBCI), the building sector has the highest chance of reducing carbon in a city in terms of magnitude compared to total implementation costs (total CO2 reduction per USD investment), compared to other sectors. This means that, strategically to achieve total carbon reduction in a city, the building sector needs to target higher carbon reductions than other sectors so that the excess carbon reduction achieved can cover the shortfall in carbon reduction for other sectors. This means that the development of energy efficient buildings alone is not enough. Thus, the building sector needs to have a program that leads to maximum carbon reduction performance i.e., the zero energy building program (ZEB). Now several countries already embarked towards ZEB program.
The new definition of ZEB has also been renewed and has recently been adopted by the International Standards Organization (ISO) under the ISO/TC 205 working group.
The initial development of ZEBs in Malaysia began in 2002 and until now some buildings have achieved that performance based on the new definition of zero energy building. In 2018, SEDA Malaysia has embarked the voluntary initiative on ZEB awareness, promotion and technical facilitation program. This includes the development of a simple ZEB performance assessment system based on the current CIDB’s Construction Industry Standard (CIS) 20:2012 – GreenPASS. Some local authorities especially those who are currently implementing the low carbon cities program especially those are targeting carbon neutral cities by 2050, interested to consider the implementation of ZEB program.

An update of some info on affordable green building system .
More than 20 years ago, the EU vowed to fight the newly identified danger of climate change. Over time, it has developed a policy which is two-fold: on one hand, it looks at ways to reduce greenhouse gas emissions inside EU borders and now has 2050 as horizon; on the other hand, it tends to lead by example and to push other big emitters to gather around similar emission reduction objectives.
Pursuing the idea of giving a price to carbon, the EU has put in place an instrument that would lead it towards decarbonisation: the Emissions Trading Scheme (ETS). Launched in 2005, it has today become a complex system which is being reproduced in other parts of the world. The ultimate vision is one of a global carbon market leading to a significant reduction of greenhouse gas emissions and thus mitigating the impact of climate change.
