“…The development of urban planning studies as regards the solar access of buildings is based on the location-orientation binomial. 14,15 However, DF is insensitive to orientation, a study considering dynamic simulations for every orientation would highlight the difference between the metrics that is very important in places where direct daylight is relevant. 5,10 In hot and dry climates, it is particularly important to take into consideration the orientation and obstructions in the surroundings, not only to ensure a minimum reception of daylight, but to avoid overheating of their interior spaces.…”

“…20 The shading effect from nearby buildings can be significant and reflected components can be the main sources of interior lighting 2,21,22 if they are not shaded. 15 This should be especially taken into account with dense construction as the presence of obstructions has repercussions on the availability of daylight and causes increased energy consumption. 23 Li et al has a lot of experience analysing dense urban environments, 21,23 but to the authors' knowledge, the effects of obstructions are studied solely in terms of DF, so a dynamic daylight analysis would be useful to consider the variability of daylighting performance not only due to building design, but also the surrounding environment.…”

During the first stages of building design, issues such as local climate, surrounding buildings and orientation are determining factors. The impact of these boundary conditions on daylight illuminances in an open-plan office space is studied in terms of daylight factor, daylight autonomy and useful daylight illuminances. Climate conditions in the location determine the characteristics of the daylight source, such as the ratio between diffuse lighting and global lighting. However, surrounding buildings and elements which may block daylight in the space hold more weight than the orientation of glazed faç ades, but are not always taken into consideration in daylighting studies.

“…The changes in building design, orientation and urban geometry have affected solar access [178]. Mesa et al [179] suggested that the optimum separation ratio between the buildings and their heights is from 0.67 to 1. Densely urban morphology enables interior spaces to achieve a lower level of natural illumination quality and intensity [179].…”

Urbanization leads to loss of vegetation and converting pervious areas into built-up and impervious areas, and consequently, urban areas expose higher temperatures as compared to surrounding rural areas, which is called Urban Heat Island (UHI). The UHI affects the urban environment and causes heat-related diseases and mortality that have increased over the last centuries. Considering the severity of the UHI problem, enormous research has been conducted and an extensive range of literature is available on this topic. This paper reviews the causes, modelling and mitigation strategies of the UHI. The urban infrastructure and anthropogenic heat sources are the main driving factors in developing the UHI in cities. Many approaches including observation and modelling techniques are used to understand the formation, causes and mitigation of the UHI. The formation and causes of the UHI largely depend on the size, shape and urban infrastructure of the cities as well as climatic conditions. Although various modelling techniques are used to study UHI, there are still lacks in all models to precisely represent the physical phenomena and complex urban infrastructure. Many UHI mitigation strategies are examined by numerous studies, while the increased urban vegetation is a more environmentally friendly solution. The study summarizes the important features and limitations of different modelling techniques and mitigation measures of the UHI. This study also identifies research gaps and proposes areas for further research.

“…A luz natural é uma fonte renovável, gratuita e abundante no território brasileiro e quando corretamente captada e distribuída pode auxiliar na redução do consumo de energia elétrica (MESA; CORICA; PATTINI, 2011;RAPHAEL, 2011;DUTRA;PEREIRA, 2014). Além das vantagens econômicas, a luz natural propícia um ambiente mais agradável, garantindo ainda melhores condições de saúde, pois exerce influência importante no ciclo biológico dos seres humanos (MARTAU, 2009;FIGUEIRÓ, 2010;SANTOS, 2014).…”

Esta pesquisa teve como objetivo investigar a performance luminosa da associação entre elemento vazado, janela alta e prateleira de luz para um ambiente interno de escritório em localidade de clima tropical úmido. Na metodologia foram feitas modelagens com o Rhinoceros3D+Grasshopper e simulações com o DIVA-for-Rhino. Como parâmetros de análises adotou-se os intervalos da UDI (Useful Daylight Illuminances), a Autonomia da Iluminação Natural (DA) e a Uniformidade. As avaliações foram feitas para Norte e Oeste para os seguintes modelos: Modelo I (elemento vazado), Modelo II (elemento vazado + janela alta) e Modelo III (elemento vazado + janela alta + prateleira de luz). Utilizando como base o Modelo III foram avaliados mais quatro modelos variando a profundidade interna da prateleira de luz. Os resultados apontaram a dificuldade de os modelos alcançarem os limites mínimos de DA (500lx) e de Uniformidade (0,6), indicando tanto a necessidade de acionamento da iluminação artificial como a existência de elevados contrastes luminosos. O Modelo III10 para Norte e o Modelo III30 para Oeste obtiveram a melhor performance em relação Ã UDI, garantindo iluminação adequada em cerca de 70% das horas, iluminando de maneira mais eficiente a região profunda do ambiente e admitindo baixos percentuais de iluminação excessiva.
