The materials are the basic elements in any type of construction activity. The construction sector consumes a handsome amount of construction materials while completing any construction project and ultimately not only depleting the natural resources but also increasing the content contribution of CO2 from construction sector. In order to save the environment for our future generations, it is necessary that such alternate materials, which are environment friendly and also cost effective, shall be adopted in the construction sector. Recycled materials are one of the choices that can be adopted in this regard. Therefore, in order to access the magnitude, it is necessary to study the effect of embodied CO2 emissions from the materials, which are used in conventional housing construction Malaysia. This study focuses on the comparative analysis of embodied CO2 emission from the conventional construction materials and proposed recycled materials used in construction of a typical low cost house commonly adopted in Malaysia. The virtual model of selected single storey low cost was developed using Building Information Modeling (BIM) concept. The results highlighted that with incorporation of proposed recycled materials, a reduction of almost 24 % of embodied CO2 emission can be achieved. The overall contribution of single storey house was observed to be reduced from 30 kg-CO2 /sq. ft to 22.65 kg-CO2 / sq. ft

The construction sector is the largest contributor to carbon emission, especially from housing development activities, which has been on high demand due to the continuous increase in the population. This study aims to analyze the amount of carbon emission produced from house building materials on peat soil, using the Building Information Modeling method. The construction of houses on peat land is different from that of hard soil, because it requires to strengthen the foundation and to minimize the load on the superstructure of the building which was performed by choosing the type of material that is suitable for the location, and is also environmentally friendly. The carbon emission was calculated using a quantitative approach, where the volume of the material used was multiplied by its emission coefficient. The volume of material was obtained using the Building Information Modeling method, while the emission coefficients were acquired by utilizing the inventory data from ICE University of Bath and several literature studies. The results showed that the types of materials that produced the largest emissions were cement, mild steel, and wood, which had 14,051.90 KgCO2eq/house, 9,565.89 KgCO2eq/house, and 7,865.75 KgCO2eq/house, carbon value respectively. After redesigning the building and replacing light steel with wood, the emission reduction was 5.01% from a total of 42,523.33 KgCO2eq/house or 2,109 KgCO2eq/house with a saving of Rp. 154,397.04 or 10.87/house. Based on data from Central Bureau of Statistics of the City of Palangka Raya, the number of houses built in Palangka Raya City reached 918 units with an average building area of 45 - 70 m2, it is estimated to save Rp. 141,397,482.72 or $ 9,978.66. It shows the importance of environmentally friendly innovations in designs and the selection of low-emission materials, which has a positive impact on finance and climate sustainability. This finding is expected to provide insights for the government in the implementation of housing construction policies that prioritize environmental factors which reduce the level of carbon produced during the construction process and its operation.
Assessment of CO2 emissions and resource sustainability for housing construction in Malaysia
International Journal of Low-Carbon Technologies, 2009
Assessment of a society's environmental load is one of the important tasks when creating a sustainable society. The authors of this paper assessed CO 2 emissions and forest resource sustainability for the housing construction taking place in Malaysia using an Input -Output analysis. Common housing types such as apartments and terraced houses were assessed. The findings showed that the main sources of CO 2 emissions during the construction phase were generated in the building components, such as building structures and foundations. The forest resource sustainability will be sustained under certain conditions, even if timber housing construction is to be promoted. This paper also discusses the methods for both CO 2 reductions and forest resource sustainability.

The Malaysian construction industry significantly contributes as an empowerment to its development vision of 2020 by reducing 40% of carbon emission. Moreover, this industry accounts as a threat to the environment, not only in terms of consumption of natural resources but also in emitting million tons of carbon emission annually. In fact, Malaysia is categorized the 30th in the world's ranking in carbon emission level. To mitigate the raise of carbon emission level from the buildings construction, several studies identified some of the effective carbon emission assessment tools for construction projects but it is lack of implementation in Malaysia. The green building index (GBI), Malaysian CIB Report has been introduced to assist the construction stakeholders in reducing the level of carbon emission and the impact of buildings on the environment. This paper presents an analysis of carbon emission from housing projects and office buildings in order to identify and quantify the main sources of carbon emission for each project and it proposes environmental friendly materials as replacement for conventional construction materials to achieve the implementation of sustainability in Malaysia.

Housing development in Indonesia is increasing annually and leads to the high demand of housing provision. In this recent time, Indonesian government facing housing backlog until 13,5 million. To solve this problem, the government then focus on housing regulation by implemented One Million Housing program from 2015. In one hand, this regulation is effective to solve housing backlog but in term of environmental awareness, this massive development leads to increasing of carbon emission. The impact is due to the building material and construction process that far from eco-friendly. For this reason, a solution is needed to reduce the environmental impact that occurs. One of the solutions that can be done is to develop a low-carbon housing design by using alternative materials that are environmentally friendly. Building Information Modelling (BIM) is one method to give a broad view regarding carbon emission of housing by integrative design modelling. This study then aims to analyze housi...

A great quantity of CO 2 is emitted to the atmosphere through the different phases of a building life cycle: in the production of materials and products, in the construction of the building itself, in the setting on site, in the exploitation, the renovations, the later rehabilitations, up to the final demolition. The present paper shows the possibility of reducing the CO 2 emissions up to 30% in the construction phase, through a careful selection of low environmental impact materials. The purpose of this study is to quantify the total amount of CO 2 emissions saved by the method presented in the particular phase of material selection within the life cycle of a building. This material selection, as well as the bioclimatic characteristics, must be defined from the early design project phase.
