“…Finalmente, quanto ao dispositivo de sombreamento, a sua adoção sempre gerou economia de energia (Tabela 5), alterando a classificação por cores dos cenários, que passaram a ocupar classificações mais altas, em comparação com os cenários sem dispositivo de sombreamento. Tal resultado está em concordância com outros estudos em edifícios de planta livre no Brasil (CARVALHO; LA ROVERE; GONÇALVES, 2010;PASQUALI et al, 2011;NEVES;MARQUES, 2017). Conforme supracitado, foi calculado um dispositivo de sombreamento único cuja máscara de sombra atingisse esse objetivo: a redução dos ganhos solares, em todas as combinações de PAF, orientação e latitude, e isso pode ser verificado na Tabela 8, a qual demonstra que ter o dispositivo de sombreamento sempre reduz o consumo energético nas situações aqui apresentadas.…”

Resumo No Brasil, os edifícios de escritórios de planta livre têm se destacado pela utilização de fachadas totalmente envidraçadas, aspecto que pode impactar diretamente o consumo de energia do ar condicionado. O objetivo deste estudo é classificar e caracterizar o desempenho energético de edifícios de escritório de planta livre em três climas brasileiros. Simulações computacionais foram realizadas no programa EnergyPlus, a fim de verificar o impacto de vários parâmetros (clima, tipo de fachada, PAF, tipo de vidro, dispositivo de sombreamento e temperatura de setpoint) no consumo de energia do ar condicionado. Os resultados, classificados em faixas de desempenho energético, mostraram que alterar de uma fachada tradicional (alvenaria) para uma fachada cortina (totalmente envidraçada) elevou o consumo de energia do ar condicionado em média 25% para Curitiba e São Paulo e 15% para Manaus; que o PAF foi o parâmetro que mais impactou esse consumo, e o tipo de vidro teve mais impacto nas maiores aberturas; que utilizar um dispositivo de sombreamento sempre gerou economia e a elevação em 1 ºC do setpoint de resfriamento reduziu o consumo, em média, até 16,4%. Tais resultados geraram as melhores combinações desses parâmetros para cada clima, podendo servir de suporte aos projetistas, no sentido de se criar edifícios energeticamente mais eficientes.

Purpose – This research paper is a literature review of the existing building retrofitting process. It proposes studying the functional, technical, and organizational issues of the green retrofit process. The purpose of this paper is to expand the domain of design framework for retrofitting existing buildings. Design/methodology/approach – The paper provides a review of the model-based design process from enrollment to evaluation stages representing the green retrofitting process in selected publications. The paper opted to review the Green Retrofit Design (GRD) process model for achieving a systematic design model of GRD development in the future. Findings – Functional and maintenance issues are mainly for new buildings, also in the field for renovation and demolishing. Publications also show that environmental, social, and technical issues are often examined separately in the decision process of GRD. Papers in the facility management scale would concentrate more on organization/legal issues. Publications with questionnaire design are devoted to the usage on life-cycle assessment on existing building, but not yet on the stakeholder management and design process and related issues. Social implications – The achievement of the study is to provide a new framework of design approach that is significant to the theoretical research, education, communication, and practical works in terms of GRD development. Originality/value – The paper not only achieves a specific sequence of practical approaches, including awareness of problems, conceptual development, and design embodiment, to meet design objectives, but also conforms to academic practice-based research of creative design taking on GRD practice.

The paper presents monitoring results from the implementation of energy efficient buildings, renewable energy supply systems and energy management in a sustainable neighbourhood in Germany. The whole quarter has low energy standard buildings, which have been monitored for heating and electricity consumption. About 80% of the heating energy demand and 50% of the electricity consumption of the whole area is supplied by a wood fired co-generation plant with 1 MW electrical output and 5.3 MW thermal power output. In summer the heat from the network is used for decentralised absorption cooling in one of the office buildings. The main performance results of this monitored area are presented and the potential for replication are discussed.
