Retrofit energético em edifícios de interesse histórico estudos de casos - edifícios modernistas em Natal. 2014. 147f. Dissertação (Mestrado Profissional em Arquitetura, Projeto e Meio Ambiente) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2014.https://repositorio.ufrn.br/jspui/handle/123456789/19523This paper addresses the theme of retrotif applied to buildings that belong to the modernist architectural production of historical interest located in the urban area of Natal . The overall objective is to identify and harmonize procedures for retrofit and architectural heritage preservation using elements of constructive analysis of expression and Benefit Cost Ratio ( BCR ) parameters established by the National Electric Energy Agency - ANEEL . The hypothesis put forward is that by stimulating the projetual year analysis , retrofit interventions , it is possible to obtain better results with projects RCB addressing the issues of preservation of architectural heritage . For both flow analysis of process solutions and proposals for action of elements and systems that seek to improve the energy performance of the building , restoring or preserving the architectural elements were developed . The proposed interventions undergo performance through computer simulations of systems such as DesignBuilder, Solar and Sun Tool. The energy results were converted to the analysis of RCB parameter and compared to the constructive expression of the project because the prenatal and intervention. From the results , a plot was constructed which results in a comparison between the RCB and the constructive expression of the simulated interventionsporAcesso AbertoRetrofitPatrimônio arquitetônicoArquitetura modernista e expressão construtiva.masterThesisCNPQ::CIENCIAS SOCIAIS APLICADAS::ARQUITETURA E URBANISMO
