Avaliação da eficiência energética segundo a INI-C da Biblioteca Pública Epiphânio Dória em Aracaju-SE

Abstract

Energy efficiency in public buildings is a topic of growing relevance, especially in buildings of historical and architectural value, in which system modernization must be reconciled with the preservation of their existing characteristics. In this context, the evaluation of lighting systems must reconcile energy consumption and the luminous quality of interior spaces. This research aims to evaluate the electric lighting system of the Epiphanio Dória Public Library (BPED), in Aracaju-SE, Brazil, according to the Simplified Method of the Inmetro Normative Instruction for the Energy Efficiency Classification of Commercial, Service, and Public Buildings (INI-C) and the Brazilian standard ABNT NBR ISO/CIE 8995-1, to verify the possibility of achieving Class A, and to propose improvements in energy and luminous performance. The research was developed in five stages: bibliographic and documentary review; architectural and lighting system survey; energy assessment according to INI-C; luminous performance assessment according to ABNT NBR ISO/CIE 8995-1; and proposition of an optimized scenario. The current scenario, although it reduces consumption by 86.7% compared to the reference condition, does not meet the INI-C lighting control eligibility criteria and remains classified as Class B. The proposed scenario (79.4% reduction) meets these criteria through independent circuits per room, achieves Class A, and increases compliance with ABNT NBR ISO/CIE 8995- 1 from 4.4% to 97.1% of the assessed rooms. It is concluded that the modernization is technically feasible and depends on the renewal of light sources, the redistribution of luminaires, and control strategies integrated with daylight.
