Abstract

Choices of material specification and construction methods can significantly change the amount of energy embodied in a building, as embodied energy content varies enormously among products and materials. Assessing the embodied energy of a material, component or whole building is often a critical and complex in nature as it dependent on architectural detailing, space-use specific specifications and available local materials and local technical know-how. The researchers are mostly focused on reducing the operational energy of the buildings because clients and users demand direct and visible energy savings. This paper deals Material efficiency in embodied energy considerations is emphasized as an important aspect of sustainable building, as indicated by the inclusion of the new basic requirement for sustainable use of resources with locally workable options to save embodied energy and energy cost for residential building as this land-use in general covers 45 to 50% of the land use in cities and Master Plans. According to the researchers, most of the buildings embodied energy relates to the structural system specifications (24%) and envelope design considerations (26%)... The option III of case III shows the maximum reduction of 52.29% in embodied energy (1.87XGJ/m2) as compared to all. The cost estimate of building materials also shows the reduction in the tune of 27.83% with respect (Rs.8934.65 per m2) to option I of Case II. The option II of the case I show the reduction of 32.91% in embodied energy (2.63XGJ/m2) and 25.73% in cost estimate (Rs.9,194.63 per m2) with respect to option I of Case II. The option III of case III indicates that the proper integrated use of alternative and low-cost technologies such filler slabs fly ash bricks in the foundation, hollow blocks of masonry and Mud chaska terracing not only reduces the embodied energy content but also reduces the unit cost of plinth area. The global warming and greenhouse gas emissions are among the biggest global problems on which material efficiency has a direct influence, so it is essential to land crucial to identify the appropriate material for the relevant component of the building to save the energy.
