Resumo: | In the world context, the consumption of electric energy has been one of the concerns related to sustainability in several constructive typologies. According to the IEA (2019), almost 15% of the world's electricity consumption is for lighting, representing 5% of annual greenhouse gas production. In Brazil, energy consumption in residential and commercial buildings, services and public buildings in Brazil, corresponds to 42.6% of the total electricity consumed in the country (EPE, 2019), with lighting accounting for approximately 22% of this total in commercial buildings (PROCEL, 2006). In view of the efficient requirements, daylight quality has a fundamental role in improving environmental conditions and, in this sense, methods and tools for assessing the quality of lighting have emerged, such as those recommended by IEA SHC Task 50 (IEA, 2016). The present article evaluates the retrofit of lighting in similar public buildings that presented significant differences between lighting projects and applications of the retrofit of lighting. The methodology included real-time monitoring of buildings in non-residential buildings, covering four aspects: energy use, retrofit costs, quality of the light environment (photometry) and user evaluation (GENTILE et al, 2016). The PBE Edifica labeling method is used to check lighting quality attributes and retrofit costs. There is real monitoring in the buildings and interviews with users. As results, there was a large cost difference between the two case studies, but it is shown that obtaining A-tag is not always a result of illumination quality. |

Según la IEA (2019),15% de la electricidad del mundo se consume con fines de iluminación artificial, lo que representa 5% de la producción anual de gases de efecto invernadero. En Brasil, los edificios residenciales y comerciales, los servicios y el público, consumen aproximadamente 42,6% de la electricidad total generada (EPE, 2019), con una demanda de iluminación de aproximadamente 22% de este total en edificios comerciales y sectoriales. público (PROCEL, 2006). Además de los aspectos de eficiencia, la calidad de la iluminación és un papel fundamental en la mejora de las condiciones ambientales y, en este sentido, han surgido métodos y herramientas para evaluar la calidad de iluminación, como los recomendados por IEA SHC Task 50 (IEA, 2016). Esta investigación evalúa comparativamente dos edificios públicos de arquitectura idéntica, con diferencias en la aplicación de retrofit de iluminación. El método utiliza como parámetros un protocolo de monitoreo, que evalúa el uso de energía, los costos, la calidad del ambiente luminoso y la evaluación del usuario (GENTILE et al, 2016). El método de PBE Edifica se utiliza para verificar los atributos de calidad de iluminación y los costos de modernización. Hay monitoreo real en los edificios y entrevistas con los usuarios. Como resultado, hubo una gran diferencia de costos entre los estudios de caso, pero se muestra que obtener la etiqueta A no siempre da como resultado una calidad de iluminación.No contexto mundial, o consumo de energia elétrica é uma preocupação relacionada à sustentabilidade em diversas tipologias construtivas. Segundo a IEA (2019), 15% da energia elétrica no mundo é consumida com fins de iluminação artificial, representando 5% da produção anual de gases efeito estufa. No Brasil, edificações residenciais e comerciais, de serviços e públicos, consomem cerca de 42,6% do total da eletricidade gerada no país (EPE, 2019), sendo a demanda por iluminação de, aproximadamente, 22% deste total em edifícios comerciais e do setor público (PROCEL, 2006). Além dos aspectos de eficiência, a qualidade da iluminação tem papel fundamental para melhoria das condições ambientais e, neste sentido, métodos e ferramentas para avaliação da qualidade da iluminação têm surgido, como os preconizados pela IEA SHC Task 50 (IEA, 2016). O presente artigo avaliou comparativamente dois edifícios públicos de idêntica arquitetura com diferenças na aplicação de retrofits de iluminação. Utilizou-se como parâmetros um protocolo de monitoramento, avaliando uso de energia, custos, qualidade do ambiente luminoso e avaliação do usuário (GENTILE et al, 2016). Foi adotado, ainda o método de etiquetagem PBE Edifica, para verificação de atributos de qualidade da iluminação e custos de retrofit. Foram realizados monitoramentos reais nos edifícios e entrevistas com os usuários. Como resultado, verificou-se uma grande diferença de custo entre os estudos de caso, mas demonstra-se que, nem sempre, a obtenção da etiqueta A resulta em qualidade de iluminação.Programa de Pós-graduação em Arquitetura e Urbanismo, Faculdade de Arquitetura e Urbanismo2021-05-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/paranoa/article/view/3206610.18830/issn.1679-0944.n29.2021.10Paranoá; Vol. 14 No. 29 (2021): January/June EditionParanoá; v. 14 n. 29 (2021): Fluxo contínuo - Janeiro/Junho1679-09441677-7395reponame:P@ranoáinstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/paranoa/article/view/32066/29542Copyright (c) 2021 Paranoá: cadernos de arquitetura e urbanismohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNaves David Amorim, Cláudia Souto, Bárbara Kelly Silva deMedeiros, Ayana Dantas de 2024-02-08T14:43:05Zoai:ojs.pkp.sfu.ca:article/32066Revistahttps://periodicos.unb.br/index.php/paranoaPUBhttps://periodicos.unb.br/index.php/paranoa/oaiparanoa@unb.br1679-09441677-7395opendoar:2024-02-08T14:43:05P@ranoá - Universidade de Brasília (UnB)false |
