Summary: This study analyzes the associations between built-environment and socioeconomic factors and the tri-exposure to greenspace and air/noise pollution in Hong Kong. The findings show that higher transit nodal accessibility, building density, building height, and land-use mix are significantly associated with a higher likelihood of being disadvantaged in terms of tri-exposure to air/noise pollution and greenspace. Conversely, more advantageous tri-exposures are significantly related to higher median monthly household income and sky view factor.

Summary: This paper proposes a remote sensing image rotation object detection method based on dynamic position information Transformer to address the problems of low accuracy and slow detection speed in existing algorithms. The method improves detection accuracy by enhancing the cross-attention operation of the decoder and iteratively updating the position information of object queries. It also improves the network's robustness for remote sensing image object detection using an image pyramid data processing method and introduces a rotating IoU matching loss function for oriented object detection to improve the accuracy of matching predicted boxes to true boxes. Experimental results on DOTA and SSDD datasets show that the proposed algorithm achieves an average detection accuracy of 73.70% and 90.3%, respectively, effectively improving the average detection accuracy of Transformer-based rotating object detection algorithms in aerial remote sensing images and providing better real-time detection performance.

Summary: This study investigates the energy impact of air handling units (AHUs) located in different positions and orientations on a building rooftop on the energy demands of air filtration. The results show that the ventilation PM2.5 concentration is equal to the ambient when positioned near the windward wall. A decrease in the filter loading rate of 33% and 60% occurs at wind speeds of 7.5 m/s and 2.5 m/s at the leeward wall. When the AHU is positioned on the windward side, there is no energy savings, but there is a reduction in energy consumption of 9.8% at the centre and 19.4% at the leeward side. Comparing the effect of wind orientation for identical AHU positions on the rooftop centre resulted in a 26-35% reduction in AE and incurred energy savings of 25.8%.

Summary: Rapid urbanization has led to urban heat islands, particularly caused by U-shaped street canyons that hinder air circulation and result in the accumulation of heat in cities. Nature-based solutions, such as street trees, can help mitigate these heat issues. However, there is a lack of refined greenery space design strategy for street canyons with different morphological characteristics. This study explored the quantitative design of greenery space in various street canyons to maximize the co-benefits of trees and mitigate urban heat islands. It found that the distance between trees and the co-benefits were positively correlated, with the maximum co-benefits occurring at tree spacings less than 0.7 times the canyon width.
