Abstract
Purpose
This study is founded on an assessment model derived by the authors in previous studies. It aims to identify the applicability of the model by using it to assess the urban design aspects of two local urban renewal projects against a set of pre‐determined performance indicators.
Design/methodology/approach
First of all, a brief on the details of the assessment model is provided. Then, this study introduces how case study can evaluate the effectiveness of the model in assessing the government‐led urban renewal projects in the real world. Afterwards, it identifies the way of selecting appropriate urban renewal projects for the case study, sets out the process of the assessment, and highlights the assessment results and its implication.
Findings
The case study conducted here has proved that the assessment model is able to produce reliable and valid assessment results for evaluation of the sustainability performance of local urban renewal projects. In addition to the assessment of the overall performance, the model also helps to identify the deficiencies of the renewal projects, and the level of satisfaction of the affected persons and the concerned parties to the renewal projects being assessed.
Originality/value
By assessing the design of two pre‐selected urban renewal projects against individual indicators through case study, it can be ensured that the model derived by the authors in previous studies is theoretically and practically feasible. In addition, this study has demonstrated that the model is able to measure the design quality and the sustainability level of individual urban renewal project in real life context.

Abstract
Purpose
The paper is a follow‐up to previous studies conducted by the authors. It aims to develop a set of valid and reliable performance indicators for evaluating the social wellbeing of the urban renewal projects carried out in Hong Kong.
Design/methodology/approach
Before identification of the appropriate indicators, the paper briefly introduces the most critical socially sustainable factors that should be considered when planning an urban renewal project. Afterwards, it highlights the criteria for the selection of indicators, and develops appropriate indicators and a corresponding point scoring system for six major social design criteria through a comprehensive literature review and with the help of a number of experts from industry and academia.
Findings
By developing relevant indicators, the concerned parties can easily identify whether a renewal project meets pre‐determined planning initiatives and social objectives. Once deficiencies are noted, relevant parties can take immediate action to rectify and refine the design accordingly. It is expected that the social wellbeing of Hong Kong citizens can be assured upon completion of a renewal project – when it has been evaluated against the benchmarks in advance.
Originality/value
By conducting a comprehensive literature review and with the help of a number of experts from the industry and the academia, the paper proposes a set of valid, reliable and representative performance indicators and corresponding point scoring system for assessing the social sustainability of the urban renewal projects.

Abstract
Purpose
This study is a follow‐up to the previous studies undertaken by the authors. The paper aims to develop a set of valid and reliable performance indicators to evaluate the environmental quality of a project in order to minimise the adverse impacts of urban renewal projects on the environment.
Design/methodology/approach
First, a brief introduction to the most critical environmentally sustainable factors that should be considered when planning an urban renewal project is provided. Then this study identifies criteria for the selection of indicators, and develops appropriate indicators and a corresponding points‐scoring system for six major environmental design criteria through a comprehensive literature review and with the help of a number of experts from industry and academia.
Findings
This study proposes a set of environmental performance indicators and a corresponding points‐scoring system for the assessment model derived in a previous study. A total of 12 indicators have been developed for six design criteria (i.e. two indicators per criterion) in which both quantitative and qualitative indicators are derived, and five different scales are adopted to score individual assessment indicators.
Originality/value
By developing relevant indicators, the parties concerned can easily identify whether a renewal project meets pre‐determined planning initiatives and environmental objectives. Once deficiencies are noted, the relevant parties can take immediate action to rectify and refine the design accordingly. It is expected that the environmental performance of a renewal project can be evaluated effectively against the benchmarks through the assessment process.

Abstract
Purpose
The aim of this paper is to: study reviews of the urban renewal practices in Hong Kong and London; compare the perceptions of the design professions in both cities on the importance of different urban design considerations when defining urban renewal strategies; and verify the applicability of London's experiences in achieving sustainable urban renewal in Hong Kong.
Design/methodology/approach
A comprehensive literature review was conducted to compare the urban renewal practices in Hong Kong and London. Questionnaires were sent to design professions in both cities who were actively involved in Hong Kong's and London's urban (re)development projects. ANOVA was adopted to compare the perception patterns in both cities.
Findings
The survey and ANOVA analysis revealed that the urban design considerations short‐listed for this study could contribute towards the sustainability of economy, environment and social equity. It was noted that the distinctive features of cities of various locations do have impacts on certain perception patterns of the professionals.
Originality/value
This article adds to the limited literature in this area and will be of interest to those involved in urban redevelopment practices.

Abstract
Purpose
The purpose of this research is to review the regulatory framework for natural ventilation design affecting the health of residents, to identify the relationship between the main components of the indoor environmental quality (IEQ) and current building designs, and to propose improvements to the design standards or guidelines especially for those related to natural ventilation controls.
Design/methodology/approach
Building designs can influence the IEQ and therefore, legislation regulating such designs should be reviewed beforehand. Afterwards, site measurements to vacant residential building blocks on two different sites are carried out to collect radon levels contained in the air within the buildings. The major purpose of this measurement is to find out the relationship between radon concentration and residential building designs.
Findings
It is found that there is room for improvement in the building laws in Hong Kong regulating building designs which affect natural ventilation and IEQ.
Originality/value
This paper contributes to the understanding of the practical needs of the construction industry and may remedy any lack of consideration of commercial reality in the research process.

Abstract
Purpose
The purpose of this paper is to review the major pieces of statutory control regulating unobstructed access. In order to ensure that all residents including those with disabilities can access places that the public is entitled or allowed to enter or to use, adequate provision of unobstructed access is required.
Design/methodology/approach
A comprehensive literature review is conducted to identify whether there is room for improvement in the building laws regulating access for people with disabilities (PWDs), in order to achieve universal access design. In order to ascertain that the universal access design is achieved in public housing estates, a set of checklists are prepared and a number of checkwalks are conducted. After completion of the on‐site survey, data analysis is adopted and the results are summarized for future reference.
Findings
This study presents the result of a meaningful and beneficial study which has investigated the accessibility of PWDs in public housing estates serving the majority of the Hong Kong population. This case study is valuable because it identifies the inadequacies of current access provisions for PWDs and highlights the areas requiring further improvement. Based on the review of existing legislative controls and the case studies, some possible solutions for improving present building regulations are generated.
Originality/value
This study investigated the accessibility of PWDs in public housing estates that affect a large proportion of residents in Hong Kong. Assessing the accessibility of PWDs in the public housing estates is a good indicator of the effectiveness of current controls over unobstructed access in Hong Kong.

Abstract
Purpose
The purpose of this paper is to review the current refuse collection systems available in major conurbations such as Hong Kong and to explore better solutions to alleviate the negative impacts of local domestic waste treatment.
Design/methodology/approach
This paper first reviews and evaluates current refuse collection methods in Hong Kong. Second, the social acceptability and financial viability of these alternative systems are investigated by means of a questionnaire survey. After analyzing the data, guiding solutions for local domestic waste treatment are developed.
Findings
The literature has shown the characteristics, the strength and the weakness of refuse collection systems commonly found in major conurbations. The questionnaire survey indicated that Hong Kong citizens supported or preferred an automated refuse collection system that could treat the refuse in a more hygienic way. Though the occupants were willing to make some financial contributions, they were unwilling to pay the amount money required to support the operation of the system.
Research limitations/implication
The study has not yet confirmed statistically the relationship between residents' health and refuse collection methods. Therefore, further researches should be carried out in future with more extensive data collection to pinpoint health hazard induced by refuse collection process.
Originality/value
This paper provides information about major refuse collection systems available in the territory, shows the perceptions and different preferences of the residents on those systems taking account of the costs they could bear. It proves the value reference for good building management.
