Resumo: | The significant increase in the electricity consumption over the past decades by the residential sector has stimulated the creation of initiatives which are aiming the energy efficiency (EE). In addition to laws that were enacted in order to increase EE, it was launched in 2012 the Quality Technical Regulation for Energy Efficiency Level of Residential Buildings (RTQ-R), which it sets parameters to be followed in the labeling of an Autonomous Housing Unit (UH). This research had as objective proposes alternatives to increase the energy efficiency level of a residential complex named My House My Life (Minha Casa Minha Vida - MCMV). Moreover, it was calculated the construction costs and evaluated the economic viability of the investment. Thus, it was evaluated the envelope and the water heating system through prescriptive method. The obtained results classified the current housing as D level and showed that a few changes are needed to reach the level A. Through thermal energy simulation it was determined by the new classification a reduction of 2/3 in electricity consumption. The increase in the construction costs to achieve the level A is lower than the cost savings over the building's lifetime. Currently, the Selic rate of 14.25% unfeasible the investment due to the opportunity cost, becoming feasible with the kWh cost higher than R$ 0.97 or with basic interest rates lower than 9.5%. |

Além de leis que foram sancionadas com a finalidade de aumentar a EE, no ano de 2012 foi lançado o Regulamento Técnico da Qualidade para o Nível de Eficiência Energética de Edificações Residenciais (RTQ-R), que define parâmetros a serem seguidos na etiquetagem de uma Unidade Habitacional Autônoma (UH). Esta pesquisa teve como objetivo propor alternativas para aumentar o nível de eficiência energética de um conjunto residencial do Minha Casa Minha Vida (MCMV), bem como levantar os custos para executá-los e avaliar a viabilidade econômica do investimento. Para tal, foram avaliados a envoltória e o sistema de aquecimento de água através do método prescritivo. Os resultados obtidos classificaram as atuais moradias no nível D e mostraram que poucas alterações são necessárias para atingir o nível A. Através de simulação termo-energética foi determinada com a nova classificação uma redução de 2/3 no consumo de energia elétrica. O aumento nos custos de construção para alcançar o nível A são inferiores à economia proporcionada ao longo do tempo de vida da edificação. Atualmente a taxa Selic de 14,25% inviabiliza o investimento pelo custo de oportunidade, se tornando viável com o custo do kWh superior a R$ 0,97 ou com taxa de juros básicos inferiores a 9,5%.Universidade Federal de Santa Maria2022-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/reget/article/view/3394910.5902/2236117033949Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET 2020-1; e12Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, v. 24, 2020.
