Contribution of the Vernacular Architecture to the Sustainability: A Comparative Study between the Contemporary Areas and the Old Quarter of a Mediterranean City

Abstract: The strongest point of vernacular architecture is the harmony between environment and buildings. Mediterranean vernacular architecture is harmonized with its local context, including culture and traditions. In addition, it respects environmental and climatic factors, construction materials, and morphology. In the past, people in Palestine built their houses according to their possibilities, needs, available materials, topography, and culture. Without any control from the government or any legal limitations or architects, it was people’s architecture, simple architecture. This paper discusses the differences between vernacular and contemporary residential buildings of the city of Nablus at the building scale. The research methodology adopts explanatory qualitative analysis and comparative synthesis methods for both the old and the new buildings of the city of Nablus and considers many parameters of residential buildings such as building materials, interior spaces, openings and vegetation, and the effect of sociocultural values on each. The outcomes of this research allow understanding how the new city residential buildings are far away from the sustainability principles and how the old city is close to it and how the architects and stakeholders could learn from the strategies of vernacular architecture.

Comparison of the environmental assessment of an identical office building with national methods

Abstract: The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The "be2226" office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amount of building elements as well as construction materials required and the operational energy demand. The building assessment was carried out using the same material and energy demand but applying the LCA approach used in the different countries represented by the participating Annex experts. The results of these assessments are compared in view of identifying major discrepancies. Preliminary findings show that the greenhouse gas emissions per kg of building material differ up to a factor of two and more. Major differences in the building assessments are observed in the transports to the construction site (imports) and the construction activities as well as in the greenhouse gas emissions of the operational energy demand (electricity). The experts document their practical difficulties and how they overcame them. The results of this activity are used to better target harmonisation efforts.

Escritórios de planta livre: o impacto de diferentes soluções de fachada na eficiência energética

Abstract: Resumo No Brasil, os edificios de escritorios de planta livre tem se destacado pela utilizacao de fachadas totalmente envidracadas, aspecto que pode impactar diretamente o consumo de energia do ar condicionado. O objetivo deste estudo e classificar e caracterizar o desempenho energetico de edificios de escritorio de planta livre em tres climas brasileiros. Simulacoes computacionais foram realizadas no programa EnergyPlus, a fim de verificar o impacto de varios 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 energetico, mostraram que alterar de uma fachada tradicional (alvenaria) para uma fachada cortina (totalmente envidracada) elevou o consumo de energia do ar condicionado em media 25% para Curitiba e Sao 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 elevacao em 1 oC do setpoint de resfriamento reduziu o consumo, em media, ate 16,4%. Tais resultados geraram as melhores combinacoes desses parâmetros para cada clima, podendo servir de suporte aos projetistas, no sentido de se criar edificios energeticamente mais eficientes.
