COMPARATIVE STUDY OF CO2 EMISSIONS AND BUILT-IN ENERGY BETWEEN MASONRY AND STEEL FRAME STRUCTURES

Abstract

The present work approaches a comparison between the CO2 emissions of the construction system in masonry and the structural system in Steel Frame. Considering that the masonry construction method is more common used in most civil constructions, where reinforced concrete is used in the superstructure and masonry in its closing, and the Steel Frame method is less common, where galvanized steel profiles are used. instead of reinforced concrete. In view of this, it was lectured on each constructive system presenting the materials that make up each system in the development of a work. Later, he developed about carbon dioxide, explaining the effects that its emission can cause in the atmosphere, which can be calculated using the “carbon footprint” technique. Finally, the calculation of the carbon footprint was carried out, demonstrating a comparison of the amount of CO2 and the energy life cycle during the constructive process of the exemplified building structure, for the two systems. At the end of the study, it was found that the Steel Frame construction system emits less CO2 into the atmosphere and has a lower embodied energy index, compared to the masonry construction system.
