“…Wind speeds in urban areas are significantly reduced due to blockage effects of buildings and other urban structures [1][2][3]. Such blockage effects are apparent in a wide range of scales, from the street level (~100 m) to the regional level (~100 km) [4].…”

“…Certain aspects of integral lighting have been proposed already in [56] Katunský, D. Lighting conditions at workplaces were examined using both practical and calculation methods [57,58], and incorporation of methods of daylight assessment into urbanization was studied by Sokol, N. [59] and Chen, K.W. [60]. These comments motivated us to carry out the current research focusing on lighting systems to improve the internal quality of the environment and workers' comfort while reducing overall energy consumption -Labat, M. [61], Gourlis, G. [62], Pham, K. [63].…”

The paper highlights the problems associated with the application of daylight and integral lighting in industrial facilities. In the case study of a multi-storey textile plant, we show how combined lighting (daylight and integral illumination) can be evaluated in production halls labelled F and G. These halls have large areas 54 x 54 metres, and are more than 5 meters high. There is daylight only on side through connected windows in a vertical position. In this paper we want to present case studies of these two production halls in the textile factory located in Kosice (Slovakia). These are halls that are lit through by daylight from two sides through external walls that are opposite or next to each other. The results of the case studies can be applied in similar production halls illuminated by a “bilateral” —a double-side daylight system and natural illumination through windows on two sides in a vertical position. Such a situation is typical of multi-storey buildings in light industry. The proposed approach of daylight factor calculation can also be applied to floor space in other similar buildings.

“…Nowadays, with the increase of urban population density, the urban structure is becoming more and more compact (Issakhov and Tursynzhanova (2022); Zhang et al (2018)). At the same time, due to rapid industrial development and worsening global warming, urban residents live in extreme thermal discomfort and traffic gas damage, especially in tropical Southeast Asian countries (Chen and Norford (2017); Santiago et al (2021); Yim et al (2010); Zhao et al (2021)). Therefore, many studies have been conducted over the past 30 years to improve air quality in the urban street canyons (Baik et al (2012); Ricci et al (2019); Antoniou et al (2019)).…”

With continuous global warming, growing urban population density and increasing compactness of urban buildings, VD (void deck) street design has become increasingly popular in city planning, especially in tropical countries. However, understanding on traffic pollutant dispersion in the VD street canyons is still at early stage. This paper quantitatively evaluates the effects of VD location and wind direction on the ventilation and traffic pollutant exposure inside the street canyon with VDs.The results show that the VD location and wind direction have significant effects on the flow field and pollutant dispersion inside the canyon. When VDs are located at the upwind building, downwind building, and both buildings, the wind directions with maximum ACH (air exchange rate) are 60°, 30° and 60°, respectively. Under seven wind directions (0°, 15°, 30°, 45°, 60°, 75°, and 90°), the VD provides higher ACH than that of the regular canyon, especially at high α (angle between the approaching wind and the canyon axis). When α = 90°, regular canyon has the lowest ventilation capacity, but ACH values of canyons with both VDs or the leeward VD are 189.1% and 177.6% of regular canyon, respectively. Also, mean K (dimensionless pollutant concentration) values of the canyon wall and pedestrian respiration plane on one side where VD is located are significantly reduced compared to the regular canyon. Therefore, when VDs are at both buildings, both pedestrian respiration planes and walls have the lowest K values, thus providing the best living environment for pedestrians and near-road residents. As α increases, the K values on both respiration planes significantly decrease except for the leeward respiration plane of the canyon with the windward VD.These findings can help to design urban street canyons for mitigating traffic pollution risk and improving ventilation in tropical cities with frequently changing wind directions.
