The decline of inner-city manufacturing industries is a global phenomenon, leaving behind vacant land and brownfield sites in cities. These post-industrial areas with their negative images of dereliction and obsolete urban environments have prompted many cities to implement various redevelopment strategies, among which is the concept of the Urban Entertainment Center (UEC), which combines shopping, recreation, and entertainment, with various public spaces. This study attempts to understand the changes that have been triggered by the revitalization strategy of UEC development in large-scale post-industrial sites in Seoul. Here, Special Planning District (SPD) regulation has been adopted to induce creative and long-term urban developments; however, this has been limited to private high-rise residential buildings. This paper examines two UEC development cases applied along with the SPD in semi-industrial areas for their achievements that differ from former implementations. Our analysis reveals several positive aspects: it provides a sustainable urban infrastructure for the region, overcomes the limitations of the SPD regulation practice, and establishes improved urban environment and design quality oriented toward public interest. The “privatization of planning” has become an issue in redevelopment projects. However, the two UEC precedents that are discussed imply that building cooperative public–private partnerships through a reciprocal process will secure more public benefit overall.

Waterfront areas in the city were occupied by industrial factories and freight ports in industrial age because of their convenience for transporting materials and resources by waterway. In the post-industrial era, as the role of the city gradually shifts from the ‘production centre’ to ‘consumption centre’, redeveloping waterfront industrial areas has become a global trend. In China, the city of Shanghai begins to redevelop its waterfront industrial areas since 2002. A main goal of the redevelopment in Shanghai is to ‘return the river to the public’, namely to open up the enclosed industrial compounds and transform industrial sites in the waterfront areas to public spaces. Focusing on the waterfront redevelopment and regeneration in Shanghai, this paper quantitatively assesses the publicness and quality of the newly created public spaces in three selected waterfront areas in the city. Drawing on the results of the empirical assessments, the paper argues that Shanghai has not achieved its goal of returning the river to the public yet. In response, the paper proposes some suggestions for policy-making aiming at improving the publicness and inclusiveness of public spaces in post-industrial redevelopment areas in Shanghai and other cities in the global south.

This study presents a data-driven retrofitting approach by systematically analyzing the energy performance of existing high-rise residential buildings using a normative calculation logic-based simulation method. To demonstrate the practicality of the approach, typical existing buildings in five climate zones of China are analyzed based on the local building characteristics and climatic conditions. The results show that the total energy consumption is 544 kWh/m2/year in the severe cold zone, which is slightly higher than that in the cold zone (519 kWh/m2/year), but double that in the hot summer and cold winter zone, three times higher than that in the warm zone, and five times above that in the temperate zone. The dominant energy needs in different climatic zones are distinctive. The identified potentially suitable retrofitting measures are important in reducing large-scale energy consumption and can be used in supporting sustainable retrofit decisions for existing high-rise residential buildings in different climatic zones.

Abstract The revival of post-industrial areas, understood as a factor determining contemporary urban development, is a key process in regeneration. Such areas attract strategic renewal projects, because despite their perfect location next to city centres, they have long been inaccessible to city residents. The backbone of the projects is provided by programmes laying out the future functions of such areas and their target users. In the past, mono-functional districts were popular but their numerous weaknesses have meant that mixed use and diversity are increasingly being introduced into urban areas today. Mixed use and diversity underlie the urban design movement known as the New Urbanism. This article assesses the role of mixed-use and diversity as the New Urbanism principle guiding the renewal of post-industrial areas. It is based on desk research and a comparative analysis of two case studies: the Paris Rive Gauche (France) and the New Centre of Lodz (Poland). The article concludes that regeneration based on the New Urbanism principle of functional and user diversity leads to an effective renewal of run-down urban areas. The applicability of other New Urbanism principles stressing the need to ensure harmony between an urban design strategy and the human scale in the revival of urban neighbourhoods is also worth considering in the long term.

Since the end of the 1990s, large-scale mega projects have been initiated in Gulf cities to enable an unprecedented urban growth and the expansion of new economic sectors. In this respect, mega projects have played a key role in redefining housing developments in Gulf cities. This paper explores the newly emerging housing typologies and their distinctive roles in defining new urban environments. The selected case studies are located in the Jumeirah District in Dubai, which can be seen as the first prototype of a large cohesive development area that has been built of nine rather differing mega projects including the iconic Palm project and one of the largest residential high-rise agglomerations in the Middle East. The paper is based on the evaluation of official planning data from each project as well as field observations. Conclusions are drawn to highlight key implications while identifying housing development tendencies.

Abstract Rats in urban areas pose health risks as they can transmit various zoonotic pathogens. Monitoring rat populations in urban areas is therefore a key determinant in risk assessments for taking adequate control and preventive measures. However, large-scale and long-term monitoring of rat populations is labor-intensive and time consuming. The aim of this study was to develop a low-cost and low-time- consuming method to gain insight into the trends of rat populations in urban and non-urban environments in the Netherlands, and to identify potential drivers of these trends. From 2014 to 2018, local municipalities or their pest control organizations voluntarily submitted quarterly overviews of rat nuisance reports in urban areas. For non-urban areas, a nationwide record of reported bycatch species from the muskrat control was used to assess a potential trend. To identify potential drivers of observed trends, employees of nine municipalities were interviewed. Rat nuisance reports from 25 municipalities were analyzed. An increasing trend in rat nuisance reports was observed in 12, a decreasing trend in 3 and no trend in 10 municipalities. In non-urban areas, no trend in the bycatch of rats was detected. The increase in rat nuisance reports was associated with a large municipality resident size. No consistent drivers could be identified, but potential drivers were discussed in the interviews. Although it was not possible to quantify their influence on the rat population trends seen, they provide direction for future studies on drivers of rat populations.

Abstract. In this paper, we present our approach for robust long-term visual localization in large scale urban environments exploiting street level imagery. Our approach consists of a 2D-image based localization using image retrieval (NetVLAD) to select reference images. This is followed by a 3D-structure based localization with a robust image matcher (DenseSfM) for accurate pose estimation. This visual localization approach is evaluated by means of the ‘Sun’ subset of the RobotCar seasons dataset, which is part of the Visual Localization benchmark. As the results on the RobotCar benchmark dataset are nearly on par with the top ranked approaches, we focused our investigations on reproducibility and performance with own data. For this purpose, we created a dataset with street-level imagery. In order to have independent reference and query images, we used a road-based and a tram-based mapping campaign with a time difference of four years. The approximately 90% successfully oriented images of both datasets are a good indicator for the robustness of our approach. With about 50% success rate, every second image could be localized with a position accuracy better than 0.25 m and a rotation accuracy better than 2°.

Trends of urbanization, densification, and telework all point to increasing exposure to ambient noise for workers. With the lockdown policies implemented in response to COVID-19, a research opportunity to study perceived noise exposure for teleworking arose. This paper presents the results of a survey on noise issues in multi-unit residential buildings (MURBs) and the consequent effects on occupants' well-being and productivity during the lockdown. Responses were collected from 471 MURB occupants across Canada. The results show that, despite the decrease in environmental noise, many are annoyed by outdoor noise, particularly from traffic and construction activities, and indicated that it affects their ability to work. Effects on ability to work from home were more frequently reported for indoor noise sources particularly airborne and impact noises coming from neighboring suites. Our findings, however, show that noise coming from occupants in the same suite (i.e. roommates and family) present the biggest issue. The findings indicate that existing noise conditions in MURBs might not be suitable for a permanent large-scale implementation of teleworking.

Elemental sulphur (So) is produced at petroleum refineries as a byproduct and a decrease in So prices has forced tens of mega-tonnes of So to be stockpiled at industrial sites. However, long-term storage of So blocks poses a potential for contamination of surface water and groundwater because of the oxidation of So to H2SO4.Two key controls on the environmental loadings of So blocks are the availability of oxygen and temperature. Three large scale So pilot blocks were constructed to evaluate the effects of controlling factors on the oxidation of So blocks and to test the effectiveness of cover technologies. One pilot block was left exposed to the environment while two others were covered with cover material of various thicknesses to keep the underlying So blocks either insulated or saturated. So block temperature, availability of oxygen and drainage water chemistry data were measured over a period of three years. The analysis of So pilot block data indicates that the pilot blocks would serve as useful analogues to commercial scale blocks. Pilot blocks temperature and oxygen profiles with depth indicate that the selected cover material could not control the temperature and the ingress of oxygen within the So blocks below the oxidation reaction. As a result, environmental loadings would remain a concern for the above ground sulphur storage sites.
