Efficacy of waste recycling is one of the key determinants of environmental sustainability of a city. Like other pro-environmental activities, waste recycling cannot be successfully accomplished by just one or two people, but only by a concerted effort of the community. The collective-action dilemma creates a common underlying difficulty in formulating workable solutions to many environmental problems. With a view to the non-excludability of the outcome, rationality drives people to free-ride efforts of others in waste recycling. To solve this free-rider problem, some scholars suggest the use of economic incentive. This article attempts to study the impacts of reward schemes on waste recycling behaviour of residents in 122 private housing estates in Hong Kong. The study is differentiable from the others as the latter mainly focus on domestic waste recycling in low-rise low-density housing while this one looks into the same in a high-rise high-density residential setting. According to the results of analyses on a set of aggregate data, reward schemes are found to have a significant positive relationship with the per-household weight of recyclables collected, keeping other things constant. The research findings suggest that economic incentives do work in promoting waste recycling in Hong Kong. Practical and policy implications follow.

PurposeThe purpose of this paper is to investigate whether consumers in Hong Kong's private housing market are willing to pay more for new apartment units with an eco‐label.Design/methodology/approachGreen or sustainable housing has recently become a new orthodoxy in the field of architecture. Governments commonly use legislation or subsidies to promote green housing. However, eco‐friendly housing provision can become autonomous without any state intervention if the consumers are willing to pay more for housing of better environmental performance. In this light, this study explores Hong Kong resident's willingness‐to‐pay (WTP) for eco‐labelled housing based on the findings of a face‐to‐face questionnaire survey. Besides, the determinants of the WTP are identified using logistic regression modelling.FindingsLess than half of the 231 respondents were willing to pay more for a new eco‐labelled apartment unit. The number of “willing” respondents dropped significantly with the label grade which signified the level of environmental performance of a property. Moreover, the decision about WTP was contingent mainly on the respondents’ household income and environmental attitude.Research limitations/implicationsThe findings of this study can offer valuable insights for the house‐building industry and policy makers into how to promote a more sustainable built environment in Hong Kong.Originality/valueNearly all previous research on green building consumerism focussed on commercial buildings and houses. As a preliminary study, this research extends the body of knowledge by exploring the WTP for eco‐labelled apartments.

A high-density built environment poses challenges to the idea of sustainable development in respect of health (e.g. SARS outbreak) and safety (e.g. fire and structural problems). To examine the seriousness of the high-density problem, this study aims to survey the health and safety performance of apartment buildings in a densely populated city, Hong Kong, using a simplified assessment scheme. An assessment scheme based on a hierarchy of building performance indicators concerning the quality of: (a) architectural design, (b) building services design, (c) the surrounding environment, (d) operations and maintenance, and (e) management approaches was developed. One hundred forty (140) apartment buildings were surveyed and assessed through site inspections, desk searches, and interviews. A performance analysis was conducted to examine and compare the overall health and safety performance of the buildings. We found that there were considerable variations in health and safety conditions across buildings, even though they are located within a single district. Most of the variations in building health and safety conditions were attributed to differences in building management systems rather than building design. Enhancing strategic management approaches (e.g. a better delineation of owners' rights and duties) appears to be the most critical factor that underperformers should consider in order to improve their buildings.

PurposeProper management and maintenance of building stock are vital to sustainable development of a city for a number of reasons, for example, the close relationship between building performance and residents' health. However, effective housing management requires active participation of the residents, particularly the homeowners. Yet, homeowners' participation in housing management in Hong Kong is claimed to remain at a low level because of its voluntary nature. This paper aims to empirically explore the determinants of participation behaviour of homeowners in private housing management in the city based on survey findings.Design/methodology/approachFounded on the literature reviewed, an analytic model for explaining homeowners' participation behaviour in housing management is developed. The model is then tested by means of logit regression with the data collected from a structured questionnaire survey conducted in summer 2009. A total of 346 respondents from 53 private multi‐storey residential buildings in the western district were surveyed.FindingsIn general, older, better educated and less wealthy homeowners are active participants in building management matters, keeping other things constant. Sense of community is also found to be a significant determinant. Besides, homeowners' approach towards building care is predominantly reactive since they engage in housing management because of their dissatisfaction with building quality. The findings of the research will provide valuable insights to public administrators for formulating better policies on private housing management.Practical implicationsThe analysis results pose a positive view towards the effects of the communitarian approach to avoid free‐riding problems in housing management. In order to heighten the participation rate of homeowners in private housing management, local authorities or other public bodies can try to boost homeowners' sense of community within their residential communities.Originality/valueThis study is the first attempt to empirically investigate the determinants of homeowners' participation in the management of high‐rise residential buildings in Hong Kong.

PurposeTo develop a multi‐criteria decision‐making framework for evaluating different schemes of urban regeneration project.Design/methodology/approachUrban decay in Hong Kong has long warranted community concern. To tackle the problem, there are generally two different approaches, namely building rehabilitation and redevelopment. In the past, urban regeneration was dominated by complete redevelopment. However, with the rise of the concept of sustainability, the choice of building rehabilitation is becoming increasingly popular. Nevertheless, with either option, difficulties are often encountered in balancing the diverse interests of the stakeholders, who have varied aims and ambitions for the achievements of a project. Therefore, we have developed a framework, which contains the factors to be considered when planning an urban renewal project. To obtain the relative importance of these factors in a reliable but reasonably inexpensive manner from the building‐related professionals, the Non‐structural Fuzzy Decision Support System was employed. In total, 34 building surveyors and 31 town planners were interviewed using structured questionnaires.FindingsThe set of perceived weightings of the decision criteria obtained from building surveyors was quite different from that from town planners. People of different backgrounds hold divergent views towards the relative importance of the decision criteria in an urban regeneration project.Research limitations/implicationsDue to the resource limitations, individuals from the professions of building surveying and town planning were studied only.Practical implicationsTo achieve a credible decision‐making process, it is therefore advisable to have a balanced mix of members in any urban regeneration project decision making panel. Also, the framework developed in this study can be used to facilitate the decision making process in the future project.Originality/valueThis paper is the first attempt to explore the relative importance of various criteria for the decision‐making process in urban regeneration projects perceived by different professionals.

The paper examines how building height is determined in the absence of building height regulatory restrictions. A model is developed for determining optimal height using simple neo-classical economic analysis; this is then tested using empirical data from Hong Kong. The results show that the observed building heights are consistent with the optimal height predicted by the model. In addition, it was also found that the point of optimality varied positively with the quality of the external environment. An important practical implication is that town planners and policy-makers can make use of the model as a benchmarking tool to assess and quantify the effect of imposing or relaxing height restrictions.

This is an empirical study on the pricing of two vertical property attributes: floor level and building height. Floor level is the vertical location of a unit in a multi-storey building; the extra price paid for a higher floor level is labelled a floor-level premium. Previous hedonic price studies unequivocally showed that the floor-level premium is positive, but they were silent on whether its magnitude varies with floor levels and with buildings of different heights. Indeed, building height is a feature of a building, not its constituent units, so it is not clear whether building height alone should affect the units' prices. Based on a sample of highly homogeneous housing units in buildings of varying heights, we found that (1) the floor-level premium was not constant, but diminished as floor level increases; (2) there was no significant difference in the pattern of the floor-level premium between high-rise and low-rise buildings; and (3) there was a positive and significant premium for units in low-rise buildings over those in high-rise ones. These findings can help developers determine the optimal height and shape of their development.
