Cálculo da eficiência energética do Edifício Vasconcelos Sobrinho (Ceagri II) da UFRPE em condições atuais e propostas de retrofit visando aumento da eficiência

Abstract

The technological evolution at the end of the past centuries has led to a greater dependence of society on the increasing use of energy sources, resulting in a collective internal migration process among countries that adopted methods of higher energy production. This trend described the movement of a significant portion of rural residents to urban centers in search of better living conditions. Thus, the beginning of the third millennium was marked by the pursuit of increasingly energy-efficient systems in line with the modernization of techniques and modes of construction and production, aiming to reduce negative impacts on environmental issues and to preserve natural resources. Due to changes over the years in the way buildings are planned, older structures have dated aspects, but often offer advantageous scenarios in terms of feasibility and execution costs when compared to the updating of their energy systems with the development planning of a new building. It is in this role that the retrofit procedure can be implemented, referring, in this case, to a set of measures and interventions carried out in an existing building with the aim of improving its energy efficiency, aiming to reduce energy consumption, increase occupants' comfort, and decrease the environmental impact of the building. With the growing challenge of energy demands and the need to reduce greenhouse gas emissions, energy retrofit emerges as a promising approach to optimize the energy performance of existing buildings. Therefore, this study aims to investigate the importance and necessity of public policy measures and financial incentives to enable and promote retrofitting in dated buildings as an effective strategy to improve sustainability and the efficiency of their energy systems. The adopted methodology includes a detailed review of scientific literature and technical standards related to the application of energy retrofit methods in buildings, heavily based on the INMETRO Normative Instruction for the Energy Efficiency Classification of Commercial, Service and Public Buildings no. 309/2022, as well as tools for the development and construction of the new model to be proposed for a selected building (Ceagri II, located near the main campus of the Federal Rural University of Pernambuco). Software and resources are assigned to outline ways to rehabilitate such a construction to meet current criteria.
