Purpose – The purpose of this paper is to examine the significance of social isolation and the factors that create social isolation for residents of inner-city high-rise apartment communities. We critically examine how the physical environment and perceptions of safety in apartment buildings and the inner-city implicate the quality of interactions between residents and with their neighbourhood community. Design/methodology/approach – The authors used mixed-methods consisting of survey questionnaires supplemented by semi-structured interviews and focus group discussions using stratified random sampling to access predetermined key strata of inner-city high-rise resident population. Using coefficient of correlation we examine the significance of the association between social isolation, age and ethnicity amongst Auckland's inner-city high-rise residents. Findings – The authors found the experience and expression of social isolation consistent across all age groups, with highest correlation between functional social isolation and “being student”, and older adults (60+ years), length of tenure in current apartment and length of time residents have lived in the inner-city. Research limitations/implications – As a case study, we did not seek in this research to compare the experience and expressions of social isolation in different inner-city contexts, nor of inner-city high-rise residents in New Zealand and other countries, although these will be useful areas to explore in future studies. Practical implications – This study is a useful starting point to build evidence base for professionals working in health and social care services to develop interventions that will help reduce functional social isolation amongst young adults and older adults in inner-city high-rise apartments. This is particularly important as the inner-city population of older adults grow due to international migration, and sub-national shifts from suburbs to the inner-cities in response to governmental policies of urban consolidation. Originality/value – By identifying two forms of social isolation, namely functional and structural social isolation, we have extended previous analysis of social isolation and found that “living alone” or structural social isolation did not necessarily lead to functional social isolation. It also touched on the links between functional social isolation and self-efficacy of older adults, particularly those from immigrant backgrounds.

This paper focuses on Ponte City, a high rise residential tower within the inner city of Johannesburg, South Africa - the highest of its kind in the southern hemisphere. This equally visually and socially notorious cylindrical building has since its erection in the 1970's become an icon and simulacrum of Johannesburg city life. It is located on the border of the suburb of Hillbrow, a restless transcendental suburb, known for its well mixed population of locals and migrant non South Africans, especially from other African countries. The inner city suburbs of Hillbrow and surround is furthermore notorious for being overcrowded and dangerous, with crime and xenophobia reaching peak statistics within the country. Famous for its peculiar shape and size, and somehow the epitome of what has and is happening in these areas, are Ponte City. It has become the first point of arrival for thousands of migrants from the rest of Africa and functions as a beehive of tangible and non-tangible systems and myths. Although it primarily provides a big concentration of homes for many, its purpose and influence has always been about something bigger - a reference to visual and structural feat, to social elitism, to African migration, and to urban legend of both horror and delight. The paper investigates the significance of Ponte as built form within this milieu of fear and transition. The building is seen as an urban body that has moved beyond the borders of its physical existence. It is described how it functions and exercises influence in the collective imaginations of its users and spectators. It also looks into how it asserts traditional definition and the significance of volatility in such inner-city environments. Experimental theories of homelessness, concept cities and cities with people as infrastructure are investigated and utilized in order to grasp a new understanding of the building within this unique milieu.

ABSTRACT Dense high-rise cities offer some advantages in terms of sustainability but have considerable downsides. Low-dense and medium-rise typologies have been shown to offer good social qualities; their potential energy and carbon advantages have received less attention. As the energy consumption, emissions of cities and heat island effects increase; we question whether dense, high-rise cities offer optimal sustainability. We discuss seven areas where medium density and lower rise typologies offer advantages in terms of energy and climate including: land use/density; microclimate/green space; energy supply; transports; operational energy/carbon; embodied energy/carbon; and resilience. The aim is to discuss the cumulative importance of these areas in the context of sustainable energy use and climate emissions. These areas are subject to ongoing research and are only discussed briefly, since the overarching synthesis perspective for urban planning is our focus. The picture that emerges when these points are seen together, suggests that medium density and lower rise options—like traditional European typologies—may offer, in addition to social qualities, very significant advantages in terms of energy, carbon and climate emissions.

Thermal environmental problems in urban high-rise buildings are prevalent. To analyze the phenomenon, the thermal environment of a typical urban residential subdistrict is simulated by using CFD techniques considering the affects of different type of wall material. The simulation data are carefully analyzed. Some useful results are thus obtained. The direction of the buildings affects air circulation greatly with the north-south orientation having the best effects. Temperature in the subdistrict is about 3~5°C higher than its surroundings because of heat island effects which could be weakened if greening rate of the sbudistrict is increased. Finally, simulation results show that wall materials affect the environment considerably.

In the 1930s New Zealand was yet to invest in inner-city living via large scale apartment buildings. Few examples of flats existed. A. Sinclair O'Connor's Courtville (1914-19) at the corner Waterloo Quadrant and Parliament Street, Auckland, and Francis Petre's Manor Place Flats in Dunedin were exceptions to conventional living. In the 1930s greater interest was shown in the design of inner-city apartments – most famously by the Department of Housing Construction's Berhampore Flats, Adelaide Rd (Wellington, Gordon Wilson, 1938-40), and Symonds Street Flats, Symonds Street (Auckland, Friedrich Neumann, 1939-47), anticipating their 1940s work: the Dixon Street Flats, Dixon Street (Wellington, 1940-44), the Maclean Flats, The Terrace (Wellington, 1943-44), the Hanson Street Flats, Newtown (1943-44), and the Greys Avenue Flats, Greys Avenue (Auckland, 1945-47). [NEW PARAGRAPH] In Wellington, Edmund Anscombe dominated the design of privately funded inner city flats, designing six art-deco/modernistic apartments during this time: Belvedere, Hamilton Flats, Olympus, Linfield, Alberts Flats and Franconia. This paper examines these apartments in the context of Anscombe's comments on house design, and housing, and his 1936 proposal to replan the area of Adelaide Road as a residential area to accommodate superblocks of high rise apartments.

The development of downtown areas causes urban heat island (UHI), which raises the temperature of cities. To remove the causes of UHI, extensive research is underway for securing green spaces and fresh air corridors in urban districts. The development of high-rise apartments in the downtown affected the fresh air corridor of the whole city, decreasing wind velocity by up to 50% compared to that before the development. In addition, with regard to apartment layout in complexes, the front-rear inter-building distance had a higher effect on the change of wind velocity in the complexes than the side-to-side inter-building distance. However, in a layout with the same repetitive form, a wide side-to-side space increased the intensity of turbulent flow in the complex, making the wind velocity almost three times higher at some parts.
