“…These strategies help reduce air temperatures by increasing urban albedo reflecting solar radiation, evaporation absorbing heat, and air flow for ventilation. A number of previous studies have also broadly explored the roles of albedo [6,7], vegetation [8,9], and air flow [5,10] to moderate air temperature at the microclimate level, as well as in cases of the UHI effect.…”

Previous studies have demonstrated that vegetation and increased air flow can mitigate air temperature by employing numerical models, satellite remote sensing or Computational Fluid Dynamics simulations. This study aimed to examine how layouts of vegetation space and wind flow affect microclimate air temperature, which directly affects city dwellers’ thermal comfort in summer, in a real apartment housing complex in Seoul, South Korea. To do this, a Reynolds-averaged Navier–Stokes model was utilized, combined with a finite volume method CFD simulation, and which measured transpirational cooling effects of vegetation by comprehensively considering air humidity by transpiration, as well as wind flow of the surroundings, to reflect actual conditions of urban environments. Based on the computational model, nine scenarios including elevated building designs were simulated. The findings of this study are as follows: First, different layouts of vegetation and wind flow clearly affected microclimate air temperature in the housing complex. Second, when the total area of vegetation was the same, it was more effective to reduce air temperature by placing it in small units rather than concentrating it in one place, and placing small vegetation spaces close to buildings was better than locating them between buildings. Third, it was apparent that an elevated space works as a wind path, leading to increasing wind velocity. However, it was revealed that wind flow does not always positively affect hot temperatures.

“…The image appearing in the bibliographical research is highly complex. The reviewed conceptual models included many variables, most of which were related to factors directly affecting the health of the inhabitants (Jensen, 2020, 95-112), such as air humidity (Psomas, Teli, Langer, 2021,198), noise (Szczepańska, Senetra, Wasilewicz-Pszczółkowska, 2020, 801), lighting (Moadab, Olsson, Fischl, 2021, 244), and the thermal environment (Jung, Yoon, 2017). Particularly noteworthy are the studies by Kadhim and Ubaid (2021, 1067), which dealt with the impact of a pandemic on the perception of architectural interiors by people who are isolated for a long time and exposed to stress from epidemiological threats.…”

The influence of global lockdowns during the COVID-19 pandemic has profoundly impacted the lives of many people. Once performed elsewhere, many activities had to be moved to private spaces of individual homes, influencing how people use their residential space, modifying their living and working conditions. The purpose of this study was to research the changes in the use of residential space through questionnaires addressed to respondents in five age groups (up to 25, 26–35, 36–50, 51–65, and over 65), and living or studying in the Milan area (Lombardy)—an area affected severely by COVID-19 in the period March–May 2020. The obtained questionnaire results allowed the authors to create a set of guidelines for apartment design, intended to improve their spatial performance. The observations made when creating the case study projects led to two main conclusions: First, at the level of the house plan, the arrangement of the plan should be free and adaptable, al-lowing for fast alteration by the user. Second, the project should be tailor-made, highly specialized, and purposefully designed at the level of home office design, including appropriate furnishings, technical appliances, and lighting systems.

“…Many scientific researches and public actions were attempted for a long time [1]. Recently, detailed analysis on the climatic impact of urban design has attracted academic interest with enhancement of simulation techniques; examples include the desirable exterior design for improving outdoor thermal environment [2], developing the guidelines to enhance the ventilation performance of existing buildings with studying vernacular architecture [3], the use of air ventilation in urban areas in order to reduce the occurrence of urban heat islands [4][5][6][7], improving pedestrian comfort [8,9], and urban designs that consider the impact of sunlight and wind [10]. Most previous studies have investigated warm regions; however, winter cities require a different approach [11,12].…”

Urban designs that consider regional climatic conditions are one of the most important approaches for developing sustainable cities. In cities that suffer from heavy snow and cold winds in winter, an urban design approach different than that used for warm cities should be used. This study presents a scientific design process (the sustainable design approach) that incorporates environmental and energy assessments that use snow and wind simulations to establish guidelines for the design of urban blocks in high-rise and high-density districts so that the impact of snow and wind can be minimized in these cities. A city block in downtown Sapporo, Japan, was used as a case study, and we evaluated four conceptual models. The four models were evaluated for how they impacted the snow and wind conditions in the block as well as the snow removal energy. Based on the results, we were able to identify the design guidelines in downtown Sapporo: an urban block design with higher building height ratio without the mid-rise part can reduce the snowdrifts and lower the snow removal energy. The proposed sustainable urban design approach would be effective in improving the quality of public spaces and reducing snow removal energy in winter cities.
