Avaliação da eficiência energética de envoltória e classificação de acordo com o método simplificado da INI-C: estudo de caso de uma EAS em Cacoal/RO

Abstract

People increasingly demand access to energy sources for various purposes and this high demand is worrying from the sustainable point of view since excessive dependence on energy can create a scenario similar to the oil crisis in the 70s or the energy crisis of 2001 in Brazil. A solution would be the production of more energy efficient buildings, since commercial and residential buildings represent 43% of energy consumption in Brazil. This paper aims to evaluate the energy efficiency level of the envelope of a public health building, following the rites and criteria of the Inmetro Normative Instruction for the Energy Efficiency Classification of Commercial, Services and Public Buildings (INI-C) and propose possible improvements. To this end, geometric and construction data of the object of study were collected in order to later use the simplified methodology described in the INI-C. The energy efficiency according to the INI-C classified the building envelope as level "C". When constructive interventions were applied to the envelope to increase efficiency, the classification could reach level "A". With these results we can conclude that the building in its current state probably has a high dependency on refrigeration to ensure a comfortable internal environment. With the proposed measures the building can perform better in terms of energy efficiency, which would reduce the need for refrigeration.
