RESUMO:

The construction industry shows itself in sharp and accelerated economic growth in several countries of the world, since buildings for residential or commercial use is a necessity of societies. This sector in all phases, including construction, operation and demolition, is a major consumer of natural resources and energy use, about 40% of the world total. With this, the energy consumption by buildings is high throughout its useful life. In this sense, studies are essential to evaluate products, processes and systems in the building sector. An important tool for assessing energy consumption by buildings is energy life cycle analysis (LCA). Thus, the proposal of this study is to apply the LCEA in public type construction by proposing and analyzing three scenarios of typology of buildings as a function of energy efficiency (conventional typology, low energy and quasi zero energy) in the context of the Brazilian Amazon region. The LCEA applied to the object of analysis showed that the university public building requires a total energy of 18,26 GJ/m² (5.071,95 kWh/m²) for the energy life cycle in the conventional typology that is currently implemented, 14,41 GJ/m² (4.001,11 kWh/m²) for what would be a Low Energy model and 15,37 GJ/m² (4.269,73 kWh/m²) for the Nearly Zero Energy model. The phase of increased energy demand in the life cycle occurred in the operational phase, requiring 81% (Conventional scenario) and 77% (Low Energy and Nearly Zero Energy scenarios). Although a comparison with this specific typology cannot be made because no data were found in the literature, but, studies performed for residential and commercial buildings (offices, hotels), life cycle energy demand ranged from 5,9 - 70, 2 GJ/m² (1.638,89-19.500,02 kWh/m²) and 47,2-153,0 GJ/m² (13.111,12-45.500,03 kWh/m²), respectively, with the operational phase requiring higher consumption, about 80-90%. It is noted that the ACVE of this study was close to the range of residential buildings. In addition, previous studies show that in Conventional and Nearly Zero Energy (self-sufficient) configurations, the total energy of the cycle was higher compared to Low Energy, another aspect that resembles the results of this study. More studies on ACVE need to be performed for buildings located in developing countries and various climatic regionalization, as the researchers point out, and when addressing the typologies of public buildings, the lack of data and information about energy consumption is legitimate, more studies need to be done.
