Embodied Energy Of Building Materials India

Although important information on embodied energy in construction materials in India is scattered in academic papers. Lesser the extraction processing and refining lower is the EE and greener the product.

Embodied energy of building materials india. Production and transport of building materials contributetoenvironmentalimpactssuchasGHGgreen. The external wall of adobe is plastered by mud mortar with Cow Dung and Sand. This study funded by the Eco-cities program in India is the first of its kind to develop a comprehensive database on the embodied energy and the global warming potential of building materials in India.

Therefore in this paper it is intended to realize the importance of embodied energy of building materials for a sustainable living. However for low-energy buildings this figure can be as high as 50. Every building is a complex combination of many processed materials each of which contributes to the buildings total embodied energy.

The table gives. Embodied energy EE of building materials comprises the total energy expenditure involved in the material production including all upstream processes such as raw material extraction and transportation. RESULTS AND DISCUSSION study is to compute the embodied energy of some common building materials used in India using process based The embodied energy value of the selected materials is approach and to propose alternative materials with low shown in table 1The embodied energy value of common embodied energy.

Embodied energy is a term that often comes up when discussing the benefits of building with natural materials over synthetic manufactured or more conventional building components. Its an important concept embodied energy is the sum of all the energy required to produce any goods or services considered as if that energy was incorporated or embodied in the product itself. A mud brick is also a fire free brick.

Cole and Kernan 1996. Although important information on embodied energy in construction materials in India is scattered in academic papers. Embodied energy is the energy required to extract process manufacture and transport building materials and components.

Total embodied energy of two types of buildings is presented in Table 5. Further energy expenditure for manufacture of building materials constitutes 2025 of Indias total energy demand 1. Defining Embodied EnergyTypical office building- 50 of embodied energy from envelope and structure- Average 482 GJm2 or 4478 MJft2- 1 MJ 0948 kBtu Breakdown of initial embodied energy for typical office building Source.

Of that a third is attributable to embodied carbon. Impact of embodied energy to construct the building is ignored. Of construction materials in India is exceeding 2 billion tonnes.

Key Principles in assessing embodied energy of materials The energy consumed in producing transporting installing maintaining and disposing of construction materials and products represents between 10 and 25 of the total lifetime energy consumption of a typical building. Embodied energy contents of different building materials and technologies were discussed in the previous sections. Materials like OPC burned clay bricks etc were found to be high.

Energy expenditure always results in detrimental emissions and pollution. The current paper deals with EE of a few common building materials consumed in bulk in Indian construction industry. The challenge we face is overwhelming and complex.

The term Embodied Energy or Embodied Carbon refers to the sum impact of all greenhouse gas emissions attributed to a material during. Aluminium Glass and Steel are high Embodied materials used in building material. Embodied energy EE of building materials constitutes the total energy expenditure for manufacture of building materials including that for raw material extraction and associated transportation.

In looking at reducing embodied energy in the building process it is important to keep in mind that more processed materials will generally have higher embodied energy. An LCA evaluation by Priopta looks at the embodied carbon or Global Warming Potential GWP of the materials used in a building. Water mixed with a building material such as straw.

EE assessment of building materials reveals the extent of energy consumed and associated GHG emissions in their manufacture. Also some reflections on building materials mostly used in Turkey are exposed in order to guide future actions. This study funded by the Eco-cities program in India is the first of its kind to develop a comprehensive database on the embodied energy and the global warming potential of building materials in India.

Embodied energy in load-bearing brick masonry buildings 23 storeyed for residential purposes is in the range of 35 GJm 2 23 24. Aluminium consumes 65 times more than the energy of steel and 15 times more than the energy of glass. Our industrys emissions currently account for 40 percent of total global annual CO 2 emissions.

Embodied energy or EE is the sum of all energy used in the construction processright from extraction of raw materials manufacture of products to their transportation and incorporation in buildings.
