ANÁLISE DE VIABILIDADE ECONÔMICA DE MEDIDAS DE EFICIÊNCIA ENERGÉTICA SEGUNDO PBE EDIFICA, APLICADO A UMA INSTITUIÇÃO PÚBLICA

Abstract

Commercial, public, and service buildings are responsible for consuming a substantial sum of the national electrical energy. This said, it is necessary to implement measures in the stages of project or renovation to increase their energy efficiency. Among the measures to reduce and classify the electricity consumption, PBE-Edifica was created, being responsible for the energy efficiency labeling in civil construction and being mandatory in public buildings since 2014. Therefore, it is necessary to analyze the viability of practices that fulfill the requirements of RTQC in the State of Espírito Santo. To do so, a public building of the city of Vitória/ES was used as a case study. The methodological stages adopted here are: survey and data collection, modeling of the case study (where a computational prototype of the real case and of the reference models was generated), computer simulation, and final analysis with economic viability studies. The building was classified with level E in the prerequisite evaluation and in the comparison of energy consumption of the models. This way, after this result, improvements were proposed to obtain label A, and the financial viability of implementation was analyzed, through NPV and payback, which proved to be viable in all scenarios.
