Influence of the Operation of Energy Consumers during the Construction of Low-Rise Residential Buildings on Environmental Pollution

Abstract

Based on the analysis of the structure of energy costs during the construction of low-rise residential buildings with walls made of bricks, expanded clay concrete blocks, permanent polystyrene foam formwork and SIP panels, two main groups of consumers were established - machines and mechanisms and infrastructure of the construction site. The performed decomposition of the consumption of fuel and energy resources (FER) at the construction site for each of the above design and technological solutions of low-rise buildings made it possible to obtain the consumption of electricity (in kW) and liquid fuel (in liters). By converting various quantitative values of energy consumption to a universal unit - kilogram of standard fuel, a comparative analysis of the total energy consumption of the construction site was carried out. Since the work of energy consumers during the construction of buildings is inextricably linked with the characteristic emissions of harmful substances into the environment, their quantitative and qualitative indicators were calculated. They were used for a comparative assessment of the state of the environment during the construction of low-rise residential buildings of various structural and technological systems.
