The need of a conceptual approach that prioritizes sustainable practices increasingly consolidates in its many forms, mainly due to the indiscriminate use of natural resources, the population growth, the access to technologies and the increased consumption. Among the approaches are the efficient energy consumption, the utilization of available daylight, and also the integration of the daylight and artificial lighting use, among others. These practices can be evaluated by certifications that exist worldwide. This study has as main objective to evaluate the level of energy efficiency in lighting systems of the Headquarters of the Court of the State of Paraná heritage listed building, located in the Civic Center of Curitiba, and to assess the potential for energy savings through design of artificial lighting and an estimate of the possibility of use of natural lighting.. The building, built in the mid-60s, was performed in concrete and glass skin and has external louvers, built in concrete and finished in white marble, peripherally support the roof structure. The study was divided in two parts: the first one to assess the energy performance of the building through the specifications of the Requisitos Técnicos da Qualidade do Nível de Eficiência Energética para Edifícios Comerciais, de Serviços e Públicos – RTQ-C, from Procel. For this, surveys were conducted on site to after apply on the requirements. The second phase, consisting of simulation using the Apolux software, solar incidence through the louvers and illuminance resulting from the existing artificial lighting and artificial lighting resulting from a possible retrofit with efficient fixtures and bulbs were evaluated. Subsequently, indicators of possible energy savings resulting from variables such as reduction in the number of lamps, lamp replacement, and possible use of daylight were presented, always respecting the value of illuminance required for the function of the building by current standards. Among the results it was attested that the building has a great potential for energy savings, around 64%, and could benefit from changes that produce an increase in energy efficiency such as improved lighting distribution in the building. The indicators suggested in this paper for the analysis of efficiency, in the case of retrofit buildings, proved to be reliable and can be applied in several studies. |
