Study of Human Embodied Energy for Masonry Work During Building Construction
The embodied energy of a building is expected to be a significant component of life cycle energy for naturally ventilated or partially air-conditioned buildings in developing nations.This necessitates a detailed understanding of various aspects of embodied energy.The non-renewable energy embodied in a building in the form of construction materials and site processes has been well explored in the literature.However,the energy expended by the human workforce during building construction has not been explored in developing nations like India.While the construction industry is heavily mechanized in developed countries,substantial amount of construction work is done manually using human workforce in developing countries.This study presents a method to estimate the human embodied energy associated with masonry work and determines the relative proportion of non-renewable embodied energy due to transportation and equipment use with the human embodied energy.Volume of masonry work completed per month and the number of masons and helpers associated with masonry work were gathered for 16 months.The total volume of masonry work completed during 16 months is 4441 cu.m.The non-renewable embodied energy required for materials manufacturing,transportation of materials to site and the equipment use for lifting blocks to the required floor was determined.Further,the human embodied energy used for masonry work was assessed.The energy used for transporting materials to site is 67 MJ/cu.m.The energy used for lifting equipment is 0.92 MJ/cu.m.The human energy used is found to be 29 MJ/cu.m.It is found that the human energy is close to 1/3 of the total energy used for on-site construction processes.
