Geração de estratégias bioclimáticas para edificações em função de diferentes zonas climáticas locais de uma metrópole

Abstract

Urban climate in metropolis manifests itself based on the characteristics of urban space’s morphology. The level of verticalization, the presence of vegetation and urban density are influencing factors of climatic variables such as temperature and humidity and develops microclimates. This research intended to generate bioclimatic strategies according to the different morphologies of the city of London, England, and evaluate if the diferences on microclimates are significant to influence the architectural guidelines. Such evaluation was established by comparisons of percentages of bioclimatic strategies’ efficiency generated by the software Climate Consultant version 6.0 in its psychrometric charts. Stewart and Oke’s proposal of local climate zones was used to grade London’s different morphologies. Weather data was enabled by the online platform Weather Underground. The analysis of the longitudinal profile of temperature revealed the formation of urban heat islands in more densely occupied areas and human activities whilst the longitudinal profile of relative humidity displayed higher values of humidity among points near bodies of water and green belts. As for architectural guidelines, psychrometric charts displayed differences up to 10% concerning bioclimatic strategies’ efficiency of heating and cooling based on which LCZ the point of interest is located. These results may be used as the foundation to future architectural guidelines to the city of London, England.
