“…Researchers who explore design strategies to secure sunlight access or enhance thermal comfort in high-density residential environments use various software tools, such as Ecotect [44][45][46], Sanalyst [47], and LadyBug [48]. DIVA-for-Rhino is used by many researchers to simulate solar environments [49][50][51][52][53]. It is a daylighting and energy-modeling plugin for Rhinoceros 3D, a nonuniform rational basis spline modeling software, and carries out parametric performance evaluations of individual buildings and urban landscapes [54].…”

Urban agriculture has become a favored activity in many cities around the world. This study explores how urban agriculture’s potential can be maximized in Seoul, South Korea, a city characterized by high-density residential complexes. It selects six existing residential complexes with representative site typologies and diverse density levels. The study’s aim is to assess the impact of various typology and density settings on percentages of ground-level surface with direct sunlight above certain thresholds during warmer seasons when crops can grow. DIVA-for-Rhino is used for simulation. The findings suggest that parallel typologies and lower density levels offer the best performance, while other combinations show mixed results. This study could benefit citizens and policymakers to facilitate urban agriculture practices around the world by suggesting feasible solutions for high-density residential developments.

“…The different effects of horizontal and vertical randomness of urban layout on the solar potential have been investigated previously [27], demonstrating that at the same floor area ratio (FAR), models with low site coverage and horizontally and vertically random distribution show a higher solar potential. A study about solar urban planning recommendations to enhance the solar accessibility in a Nordic urban environment [28] also demonstrated that by optimizing the urban morphology and choosing the finishing materials during early design phases, the solar potential can be increased by up to 25%. In the context of Slovenia, the solar potential of the existing building stock in terms of minimum solar exposure of the building envelope was examined previously [29].…”

“…Parts of the method have been used in previous studies. Specifically, the method of linking VDF on the facade to DF in the room has been employed before by Iversen et al for the investigation of urban canyons [33], while the urban geometric model of nine buildings, with the central one being analyzed, has been used in a study about solar accessibility by Lobaccaro et al [28].…”

Daylight Provision Requirements According to EN 17037 as a Restriction for Sustainable Urban Planning of Residential Developments

The attempt at a more sustainable land use by increasing urban density may have a negative effect on the daylighting of residential buildings. In densely built areas, obstructions generated by the surrounding buildings can substantially reduce the available amount of daylight, causing poorly daylit spaces and a less healthy indoor environment with higher electricity consumption as a consequence of artificial lighting. European standard EN 17037, Daylight in Buildings, was established in 2018 to ensure appropriately daylit spaces. In this paper, a three-step methodology was developed to investigate the relationship between certain urban planning parameters and the daylighting of a typical room defined by specific (Slovenian) legislative restrictions about its geometry and minimum required window to floor area ratio, in order to establish the maximum densities of residential developments still fulfilling the minimum requirements for daylight provision defined by EN 17037. The results show that a relatively low urban density is required to fulfil the stipulations for minimum daylight provision for the deepest permissible room according to the Slovenian legislation. The impact of the development floor area ratio on the daylighting potential of buildings was identified as significant, followed by the site coverage, development layout, and building typology. Furthermore, the developed methodological approach clearly demonstrates a substantial potential for application in urban planning, with indoor daylight environmental conditions being linked to the planning of residential developments in the earliest stages of the project.

“…An estimated three billion people living in urban areas throughout the world are directly exposed to problems related to urban heat island intensity (UHI), which are expected to increase significantly in the near future (Tong et al, 2005;Memon et al, 2008). Several studies have addressed this theme in several different urban climates due to the worldwide severity of the problem, and a wide range of literature is available on the subject (Silva et al, 2010;Salvati et al, 2017;Lobaccaro et al, 2017;Rafael et al, 2017).…”

Urbanization modifies the heat balance in urban areas and has negative effects on landscape, aesthetics, energy efficiency, human health and the inhabitants’ quality of life. This work evaluated future scenarios of bioclimatic conditions for João Pessoa, a humid tropical city in Northeast Brazil. The scenarios were determined based on trends in air temperature, relative humidity and wind speed for the time period from 1968 to 2015. The study was performed for two distinct periods of three months each (dry and wet seasons) using data from weather stations equipped with thermo-hygrometers and cup anemometers located in nine representative areas of the city. Trends in air temperature, relative humidity, wind speed, and effective temperature index (ET index) time series were evaluated using the Mann-Kendall test. Results indicated that the air temperature showed an increasing trend of 0.34°C/decade, whereas the relative humidity showed a decreasing trend of 0.49%/decade and the wind speed values ranged from 1.3 ms-1 to 3.80 ms-1. These trends are statistically significant according to the Mann-Kendall test (p<0.05). The air temperature increased between the 1980s and 2010s, which corresponds to a period of rapid urbanization of the city. Future environmental conditions in João Pessoa will be determined in accordance with the urbanization processes.
