Aplicação de modelo conceitual de retrocomissionamento no Retrofit de edifícios públicos

Abstract

In order to act in the reduction of electric power consumed by public constructions, in Brazil, it was instituted the Normative Ruling number 02/2014, which defines rules of energy conservation into projects and respective federal public buildings which had retrofit. For this reason, it is seen a potential of contribution related to the process of retro-commissioning because this is a process of quality control which ensures that the project, the installation and the operation of machines and systems serve the owner requirements. In addition, the computer simulation is integrated, a tool which helps the building analysis related to its energy performance. However, preview studies show that as for the retro-commissioning development process as for the simulation, it is necessary the building data which, in case of existing buildings, may get difficult the use of retro-commissioning process in retrofit from these buildings. This way, the goal of this study is to set conditions for the operationalization of retro-commissioning into the retrofit of public buildings. For this purpose, it was done a literature review about the retro-commissioning and retrofit processes and, about the computer simulation of buildings. After that, it was done two case studies. The first study, which the aim is to analyze the modeling process and thermo-energetic simulation of an existing public building, searched to identify the main difficulties to its development. The second study, the goal was to identify generated data and how they are stored during the public building existence, based on interviews with employees of a federal institution of college degree who worked into the construction and maintenance departments. At the end, it was developed a model to the retro-commissioning insertion with thermo-energetic simulation in the retrofit process of public buildings and, it was proposed good practices to the management information, in order to ensure that the building data and their systems may be stored and kept updated.
