Daylighting improves users’ experience in visual comfort, aesthetics, behaviour and perception of space and plays an important part in enhancing the health and wellbeing of occupants inside a dwelling. However, daylighting design is challenging for high rise living since configuration of multiple apartments together often results in deep plans and wrongly oriented apartments with poor daylighting. Melbourne considered as the most liveable city in the world has witnessed a boom in high rise apartments in recent years, where bedrooms were designed without windows or with one small opening. Previous studies indicated that one out of two apartments in Melbourne’s central business district (CBD) failed to provide daylighting in the bedrooms. This has led to amendments in planning policy with the aim of providing access to daylight in all habitable rooms. This paper investigates the daylighting conditions in apartment buildings using field measurement and daylight simulations. Daylight levels in 12 apartment units in Melbourne CBD were measured. Additionally, daylight simulations were conducted to identify ways for optimizing light levels in standard layouts. The field measurements showed that daylighting levels were insufficient in one third the apartments due to the presence of deep floor plates and external obstructions. The results from the daylight simulations showed that window to floor area ratio (WFR) of approximately 30% is required for achieving acceptable daylighting levels in bedrooms that have south orientation.

Distance Formula

In this work, we proposed a theoretical framework inspired by physical thermodynamics to explain the housing price distributions in monocentric cities. In the same spirit as the Alonso–Muth–Mills (AMM) model, we assume that the disposable income [Formula: see text] after renting a home a distance [Formula: see text] from the center of a city is determined by the wage [Formula: see text] generated at the point-like Central Business District (CBD), the rent [Formula: see text], and the transportation cost [Formula: see text]. Unlike in the AMM model, where the scaling exponents are phenomenological, we admitted only physically reasonable exponents for the scaling of various quantities with distance [Formula: see text] from the CBD. We then determine the equilibrium rent [Formula: see text] by requiring [Formula: see text], where we assumed for simplicity the utility function [Formula: see text] (representing the demand side) has diminishing return in [Formula: see text]. In the simplest model, the equilibrium rent is given by [Formula: see text], i.e., the scaling of [Formula: see text] with [Formula: see text] is entirely determined by [Formula: see text]. We then introduce additional home availability [Formula: see text] (representing the supply side) into the simple theory in the form of an entropic correction, [Formula: see text]. The equilibrium rent then becomes [Formula: see text]. This allows us to treat additional availability due to the two-dimensional nature of cities, as well as that due to high-rise buildings on equal footing. Finally, we compare the equilibrium theory against urban data in Singapore, London and Philadelphia. For Singapore, we find quantitative agreement between theory and data. For London, we find only qualitative agreement between theory and data because the transportation cost is zone based. For Philadelphia, the home price distribution is very different from Singapore and London, and shows clear signs of economic segregation, which is difficult to treat in our equilibrium theory.

Building Loads

In metropolitan areas, the static load of high-rise buildings may result in uneven settlement, which seriously threatens residents’ living safety. Studying the response relationship between the additional stress of high-rise buildings and foundation settlement plays an important role in ensuring the safe development of metropolitan cities. Firstly, based on Persistent Scatterers Interferometric Aperture Radar (PS-InSAR) technology, we used 68 descending TerraSAR-X images to obtain the surface settlement in the study area from April 2010 to October 2018, which were validated with leveling benchmark monitoring results. Secondly, we calculated the additional stress of the building loads to quantify its effect on the uneven settlement in the Central Business District (CBD) of Beijing. Finally, two sets of characteristic points were selected to analyze the response relationships between foundation settlement and additional stress generated by building loads. The findings show: (1) The surface settlement rate varied from −145.2 to 24 mm/year in the Beijing Plain. The InSAR results agree well with the monitoring results derived from the leveling benchmark; the Pearson correlation coefficients were 0.98 and 0.95 in 2011–2013 and 2015–2016, respectively. (2) The stress results show that the depth of the influence of the static load of high-rise buildings was 74.9 m underground in the CBD. (3) The spatial distribution pattern of the additional stress is consistent with the foundation settlement. A characteristic point with greater additional stress in the same group has a higher foundation settlement rate. This relationship has also been found between the uneven foundation settlement and additional stress gradients. These findings provide scientific support for mitigating economic losses due to foundation settlement caused by additional stresses derived from building loads.

Group Profile

Pedestrian activities usually influenced by the pedestrian perception on the quality of the built environment of a city. Challenges faced by local authorities in providing facilities that are suitable for each group of pedestrians due to lack of information on the pedestrian profiles pattern. Therefore, the objective of this paper is to assess on the pedestrian profile pattern in one of the Central business district within Kuala Lumpur City Center that are among the highest pedestrian volume and adequate pedestrian facilities. On-street questionnaire survey was conducted first in order to ensure that the existing pedestrian facilities of the selected area were between acceptable to good quality range. The parameters includes are overall travel experience, sidewalk condition, aesthetic and amenities, crossings, street furniture, personal safety and adjacent traffic. Then, Pedestrian classification counts were carried out on afternoon peak-hour for one whole week. From the result, similar pedestrian profile pattern were observed on Monday to Thursday and the number of trips made increased on weekends for both count location. The result also shows that female pedestrian, especially in the 18 to 34 age range made the highest number of trips. In overall, the female pedestrian used the existing pedestrian facilities more than male for every group profile except for elderly person with disabilities/with prams.

Crime is a manifestation of incivility that society attempts to curb, yet faces enormous challenges, as crime is a by-product of urbanization and human advancement. As more agglomeration of the population in cities around the globe, humankind’s safety from being threatened by crime needed to be safeguard to sustain everyday living in cities. Humans’ co-existence with crime and fear of crime in cities vis-a-vis efforts preventing it from occurring has been widely carried out in developed countries. An increasing trend is showing in emerging and developing countries. Therefore, this article provides empirical evidence regarding a safe city program launched in Malaysia. This study aims to identify the factors contributing to the prevention of crime and fear of crime. This study employed a survey questionnaire to 400 pedestrians’ perceptions of Kuala Lumpur city’s central business district. The result showed that prevention methods through the actor of “capable guardians” (i.e., authorities) are effective; however, methods through the actor of “suitable victims” (i.e., communities) is ineffective. Further studies should explore perspective of the actor of “likely offenders” (i.e., criminals) to fill in the gap of safe city program’s effectiveness and sustainability.

Available Information

Recent earthquakes in New Zealand not only highlighted the vulnerabilities of the existing building stock but also the need for: (i) a better understanding of the building inventory, and (ii) easy access to information for quicker response after an event. In the case of Wellington, efforts over the years by the City Council and other stakeholders have produced a number of useful datasets about the building inventory. These available datasets when put together are critical in understanding the composition and characteristics of the building inventory in Wellington. This paper describes the available information, and the process to combine the different strands of data possessed by multiple stakeholders into an effective and usable multi-disciplinary building inventory database for Wellington’s CBD. The uses and future directions for this collated database are also discussed.
