Abstract

Constrained by requirements of efficiency and economy as well as tight building regulations, Hong Kong's high-density residential architecture is very different from architectural approaches that are typically taught in the architectural studio. This paper reports on a second year architectural studio project taught at The University of Hong Kong that uses the Open Building paradigm to integrate the constraints of a high-density environment, community considerations and building technology in the context of a mixed use programme to be constructed on small individual lots.

Following a series of short introductory exercises, the main studio assignment required groups of students to negotiate the design of individual projects and community areas within a given generic structural frame. Based on their individual design ideas and architectural programme, students developed a structural solution following a kit-of-parts approach. We describe the tasks and rule sets given as the studio framework and discuss students' response to this new type of architectural programme. Based on our experiences, we critically review initial studio settings, final outcomes and observations made during the teaching and learning process with regard to future implementations of similar open building studio projects.

Abstract

Purpose

The aims of this paper is to establish an appropriate physical-change-based renewal (PCBR) projects selection mechanism capable of selecting the combination of the PCBR projects that can make up an integrated urban renewal program in high-density cities.

Design/methodology/approach

The research design follows a sequential integrated methodology that combines the calculation algorithms of Fuzzy Analytic Network Process (Fuzzy-ANP) with Zero-One Goal Programming (ZOGP) to support decisions for the selection of PCBR projects. In the first phase, general criteria for assessing the sustainability performance of PCBR projects were collected from relevant literature. In the second phase, the Fuzzy-ANP was used to identify the priority weights of the candidate projects through clarifying the interdependent degree between the criteria and candidate projects. Finally, ZOGP method was selected as a predetermined number of PCBR projects among candidate projects.

Findings

The feasibility and effectiveness of this hybrid approach is then verified in a case study of Yuzhong District, Chongqing in China. The results of this study indicate that the integrated method is capable of directing the decision maker toward the best compromising solution of PCBR program that can achieve the maximization of sustainable benefits and allocate limited resources most efficiently.

Originality/value

The novelty of this paper consists in combining the algorithms of the Fuzzy-ANP method with those of the ZOGP model that serves as an effective analysis tool to address practical decision problems. This is the first hybrid algorithms to make PCBR projects selection decision that reach the maximization of the sustainable benefits, both in economic and socio-environmental terms.

Abstract

Purpose

The British Library (BL) faces a significant challenge with storage space predicted to run out within the next three years. However, alongside a plan to create additional capacity, the BL also intends to take the opportunity to rethink the integration of storage and workflows in order to implement a fully optimised end-to-end model of content management. This approach will incorporate not only storage and workflow design and integration, but also the physical environments and facilities for staff and users.

Design/methodology/approach

This paper draws on years of experience in the context of systemic industry changes to lead the reader into new thinking and opportunities in relation to print preservation and access. It should be noted that some of the aspirational new thinking described within this article may not come to fruition due to construction market inflation and resulting budgetary constraints.

Findings

As the national library of the UK, BL, like all libraries, has the responsibility of storing (preserving) its collections while making them accessible to everyone. Traditional models of physical storage can often operate in isolation from the processes that accompany them – creating silos of materials, completely remote from either the acquisition and description processes that precede their storage, or misaligned with the processes in place to support access.

Practical implications

The presentation of this conceptual thinking could help inform other libraries planning to build new print repositories.

Originality/value

The strategic approach outlined within this paper has adopted ideas and concepts from non-library applications, bringing them together to form a holistic solution that delivers the ultimate aims of a library within a modern context.

Abstract

Purpose

This study applies theoretical perspectives from urban, environmental, and organization studies to examine if “smart growth” represents an ecological restructuring of the political economy of conventional urban development, long theorized as a “growth machine” (Molotch, H. (1976) The city as growth machine: Toward a political economy of place. American Journal of Sociology, 82, 309–332; Logan & Molotch, 2007); the purpose is to determine if there is a “smart growth machine.”

Design

Nine smart growth projects (SGPs) in four cities in California and Oregon were identified and semistructured interviews were held with the respective developers, architects, and civic officials involved in their implementation process. Comparative, descriptive, and grounded approaches were used to generate themes from interviews and other data sources.

Findings

The findings suggest that an ecological modernization of urban political economy occurs through the coordination of entrepreneurial action, technical expertise, and “smart” regulation. Individual and institutional entrepreneurs shift the organizational field of urban development. Technical expertise is needed to make projects sustainable and financially feasible. Finally, a “smart” regulatory framework that balances regulations and incentives is needed to forge cooperative relationships between local governments and developers. This constellation of actors and institutions represents a smart growth machine.

Originality

The author questions whether urban growth can become “smart” using an original study of nine SGPs in four cities across California and Oregon.

Abstract

Purpose

The paper aims to analyse the Shenzhen housing market.

Design/methodology/approach

The paper uses an empirical case study using hedonic modelling that includes not only the property specifics, but also the spatial (via {X, Y} coordinates) and household (buyer's) characteristics. Two expansion models are employed to examine the spatial and socio‐economic heterogeneities in housing attribute prices.

Findings

The results provide strong evidence that the marginal prices of key housing attributes are not constant but vary with household profile and absolute‐location context within Shenzhen's housing market.

Research limitations/implications

Examining housing market behaviour in major Chinese cities should eventually be approached more explicitly with the development of China's official statistical system.

Originality/value

Largely supported by the valuable transaction data, this paper makes initial and valuable attempts to examine the interaction behaviour between property specifics, location coordinates and buyers’ characteristics within one of the very complex and immature housing markets, namely Shenzhen, China.

Abstract

Purpose

This paper aims to investigate the impacts of introducing voids combinations on natural ventilation performance in high-rise residential building living unit.

Design/methodology/approach

This study was carried out through field measurement and computational fluid dynamics methods. The parameters of the study are void types and sizes, and a wind angle was used to formulate case studies.

Findings

The results indicate that the provision of a single-sided horizontal void larger by 50% increase the indoor air velocity performance up to 322.37% to 0.471 m/s in the living unit and achieves the required velocity for thermal comfort.

Originality/value

Passive design features are the most desirable techniques to enhance natural ventilation performance in the high-rise residential apartments for thermal comfort and indoor air quality purposes.

Abstract

Purpose

To explore the risk management, crisis management and business continuity management (BCM) practices of facilities managers responsible for a range of major public and private buildings in Sydney, Australia.

Design/methodology/approach

The research method involved a survey of facilities managers responsible for the management of 27 potentially vulnerable buildings in the Sydney metropolitan area, Australia.

Findings

The results suggest that facilities managers under estimate the vulnerability of buildings to terrorist attack, may have a misconception about likely targets and may be unprepared for such an eventuality.

Research limitations/implications

These findings are restricted to the restricted sample of facilities managers interviewed who were responsible for a range of major public and private buildings in Sydney, Australia.

Practical implications

Highlights the security responsibilities of facilities managers in the new security environment and practical measures which can be taken to improve terrorism preparedness, recovery and response.

Originality/value

Buildings, infrastructure and public spaces have increasingly become the focus of terrorist attacks. Yet little is known about the level of preparedness to deal with this eventuality. This paper presents a critique of the literature on terrorism applied to building facilities, integrating the literature on crisis management, BCM and risk management.

Abstract

Purpose

Despite carbon reduction commitments, many constraints hinder the delivery of low-carbon buildings (LCBs) in high-rise high-density cities. The collaborative commitment of relevant stakeholders is vital to effectively address and mitigate these constraints. Hence, this study aims to comprehensively explore the required stakeholder collaboration attributes to address and mitigate the “common” constraints of delivering LCBs by focussing on several high-rise high-density cities.

Design/methodology/approach

A list of 21 “significant and common” constraints was identified through a systematic literature review followed by a questionnaire survey covering five economies (Hong Kong, Singapore, Australia, Qatar and the UAE). Nineteen influential stakeholders/stakeholder categories were identified through the literature, and their ability to influence the 21 constraints was mapped and identified through a two-round Delphi survey of 15 experienced professionals. The Delphi survey findings were analysed through social network analysis (SNA) methods to assess the stakeholder engagement and collaboration attributes.

Findings

The SNA results revealed the ability of stakeholders to influence the constraints, required collaborative stakeholder networks to address the constraints, significance of stakeholders according to the SNA centrality measures, core and periphery stakeholders and individual co-affiliation networks of core stakeholders.

Originality/value

While achieving the planned primary target of exploring stakeholder collaboration and their significance through SNA, this study also presents a useful sequential methodological approach for future researchers to conduct similar studies in different contexts. The findings also provide a foundation for accelerating the delivery of LCBs by strengthening stakeholder collaboration.

Abstract

Purpose

The purpose of this paper is to provide an overview of the economics of providing well-located housing in the inner city of Cape Town. The paper emphasises the need to maintain an appropriate balance between the viability and affordability of the product offered to the market and overcoming the value versus cost challenges. While developers have limited influence over value, they do have influence over cost structures through the development approach that is chosen. Moreover, local authorities influence the viability of projects through standards and regulations. The conclusion drawn from the research has considerable implications for the formulation of market-driven housing policy interventions.

Design/methodology/approach

In addition to the review of urban economics theory and the literature on the drivers and costs of inner-city, higher-density residential development, a series of interviews with inner-city residential developers was conducted to access current property development cost data and to identify the parameters that determine the viability of inner-city, high-density residential development.

Findings

Cape Town, like other South African cities, suffers from being inefficient and inequitable largely due to its low density and sprawling nature. As a result, most planning- and housing-related policy interventions advocate the provision the higher-density, more affordable residential housing in well-located areas such as the inner city. However, to date, these policies have, on the whole, been unsuccessful in achieving these outcomes. This paper argues that this is because these policies largely do not take urban economics into account and fail to address the value versus cost tension that needs to be overcome to allow for the provision of such accommodation. Based on the viability calculations provided, the research illustrates the main cost drivers associated with higher-density, inner-city residential development and makes certain recommendations as to how these cost barriers can be reduced.

Research limitations/implications

Financing arrangements and taxation implications have not been accounted for as these are often specific to the developer and thus cannot be generalised.

Practical implications

The solutions put forward by the paper offer lower-income households the ability to successfully compete with higher-income households and other land uses for well-located space in Cape Town’s inner city.

Social implications

The findings of this research illustrate the type of interventions that the public and private sectors can consider to improve the viability and affordability of affordable housing units in city centres located in emerging countries.

Originality/value

While traditional urban economic concepts are drawn upon, the paper contributes to addressing the challenge of providing higher-density, more affordable accommodation in South African inner cities. It does this by applying these well-known concepts to the inner city of Cape Town and draws on current data and developer views to accurately diagnose the problem and, in turn, to offer pragmatic solutions.

Abstract

Purpose

Density optimization is the first critical step in building additively manufactured parts with high-quality and good mechanical properties. The authors developed an approach that combines simulations and experiments to identify processing parameters for high-density Ti-6Al-4V using the laser powder-bed-fusion technique. A processing diagram based on the normalized energy density concept is constructed, illustrating an optimized processing window for high- or low-density samples. Excellent mechanical properties are obtained for Ti-6Al-4V samples built from the optimized window.

Design/methodology/approach

The authors use simple, but approximate, simulations and selective experiments to design parameters for a limited set of single track experiments. The resulting melt-pool characteristics are then used to identify processing parameters for high-density pillars. A processing diagram is built and excellent mechanical properties are achieved in samples built from this window.

Findings

The authors find that the laser linear input energy has a much stronger effect on the melt-pool depth than the melt-pool width. A processing diagram based on normalized energy density and normalized hatch spacing was constructed, qualitatively indicating that high-density samples are produced in a region when 1 < E* < 2. The onset of void formation and low-density samples occur as E* moves beyond a value of 2. The as-built SLM Ti-6Al-4V shows excellent mechanical performance.

Originality/value

A combined approach of computer simulations and selected experiments is applied to optimize the density of Ti-6Al-4V, via laser powder-bed-fusion (L-PBF) technique. A series of high-density samples are achieved. Some special issues are identified for L-PBF processes of Ti-6Al-4V, including the powder particle sticking and part swelling issues. A processing diagram is constructed for Ti-6Al-4V, based on the normalized energy density and normalized hatch spacing concept. The diagram illustrates windows with high- and low-density samples. Good mechanical properties are achieved during tensile tests of near fully dense Ti-6Al-4V samples. These good properties are attributed to the success of density optimization processes.
