AVALIAÇÃO TÉCNICA DO POTENCIAL DE TRANSFORMAR UMA EDIFICAÇÃO MILITAR EM EDIFICAÇÃO DE ENERGIA ZERO

Abstract

The concept of zero energy applied to military buildings is an excellent option to meet the energy demands of the military environment and to reduce the high consumption of buildings. The buildings of the Brazilian Army must be classified with level A in the National Energy Conservation Label. Distributed generation has grown in Brazil, with a large share of photovoltaic systems. The objective of this work was to evaluate the design of a military building for the Brazilian Army to transform it into a Zero Energy Building (EEZ) with photovoltaic systems to compensate for the reduced energy demand. The computational simulation method of INIC was applied in DesignBuilder and the generation estimates of the photovoltaic system were obtained using SAM (System Advisory Model). The building project was classified as level A, with a 59.5% reduction in consumption compared to the reference building. The analyzed photovoltaic systems (c-Si and CdTe) met the annual demand with productivity values of 1,571 kWh/kW and 1,586 kWh/kW and Performance Ratio (PR) of 0.79 and 0.80, respectively. The optimization analysis of the orientation of the building resulted in a small impact on energy consumption; however, in photovoltaic generation the impact was considerable, since in the optimized orientation the generation was 11.3% greater.
