Parâmetros para certificação energética de edificações de valor histórico e cultural

Abstract

Energy efficiency has become an increasingly discussed topic in society and at the scientific community. However, studies that relate this theme to historic buildings are few compared to contemporary buildings. However, the potential for reducing energy consumption for historic buildings is considerable, and can assist in global energy efficiency goals. This research aimed to propose parameters to improve the INI-C, aimed at assessing the energy efficiency of buildings of historical and cultural value. For this purpose, a cut was made between the listed assets in the city of Vitória – ES, in order to cover all the historical construction methods, which resulted in four buildings. The selected buildings were: Anchieta Palace, Maria Ortiz School, Superintendence of the National Historical and Artistic Heritage Institute - IPHAN in Espírito Santo and Solar Monjardim Museum. The methodology adopted in the research had eight stages: (1) definition of buildings; (2) data survey relating to buildings and identification of the construction methods, as well as the calculation of the thermal properties of the predominant construction techniques; (3) labeling the efficiency of the envelope of buildings using the prescriptive method proposed in RTQ-C; (4) creation and configuration of virtual models of buildings, with the aid of the computer simulation program DesignBuilder, version 3.4.0.401; (5) calibration of the models; (6) labeling of efficiency of the envelope of buildings using the simulation method proposed by INI-C; (7) establishment of parameters for energy labeling of historic buildings, facing the envelope, and subsequently carrying out a new labeling with the same method, using the proposed parameters. The construction techniques studied were stone and lime, the “pau-a-pique” and solid ceramic brick. The results showed that the RTQ-C labeling achieved the same levels of efficiency for all buildings; those carried out with INI-C achieved differentiated labels, as well as those carried out with the proposed parameters, that presented results more consistent with the reality of historic buildings
