Abstract

The Indian construction industry is one of the largest in terms of volume of non-renewable resource consumption. In Sustainable buildings (i.e. for example construction materials like bricks, cement, iron) are designed based on efficient use of available natural resources, balancing environmental, economic and societal impacts to meet today’s design objective while considering future impacts. The energy consumption is required for the production of building materials or products. In the aspect of environmental sustainability, the embodied energy analysis is used as a construction design assessment tool. The process-based analysis study was found to be more suitable for the embodied energy evaluation of building materials, especially for the Indian construction industry. A case study was conducted to evaluate the energy consumption of brick industry in West Godavari region. From the life cycle assessment analysis, the total embodied energy of clay-fired brick was ranging between 4.9 GJ/m3 to 7.8 GJ/m3, and the total embodied energy of fly ash blocks and AAC blocks in rang between 2.4 GJ/m3 to 4.5 GJ/m3. Thus, comparing the embodied energy of fly ash, AAC blocks, and conventional bricks, it can be concluded that fly ash and AAC blocks overall provide a sustainable alternative.
