An understanding about the criteria determining the successful application of green features, and the barriers to implementation is essential in order to promote and enhance green building development. The purpose of this paper is twofold: first, the criteria determining the success of GBFs; and second, the barriers to implementing GBFs in Hong Kong.

A multi-method approach comprising a comprehensive questionnaire survey and a semi-structured group discussion with construction professionals, along with three case studies was adopted to address these two issues.

Findings suggest that although environmental performance is the most significant criterion, the living quality of occupants and the costs of green features play a crucial role in determining the success of their application. However, the environmental aspects of buildings are not sufficient for rating or determining the greenness level of a building. As for barriers, the green cost implications; the structural unsuitability of the current stock of old buildings; and the lack of financial incentives were found to be crucial barriers preventing the application of green features in the Hong Kong building sector.

GBFs have received extensive attentions by the academia and industry. This paper used a mix method approach by exploring success criteria and barriers to implementing green features in the building sector in Hong Kong. As green building development is still a contemporary subject of discussion, this study would be beneficial to decision makers as it identifies the criteria determining the success of green building adoption and barriers to implementation of such features. Hence, relevant stakeholders will have better understanding of the factors affecting the adoption of GBFs.

Criminal proceedings can only follow the commission of an offence, made so by statute. If an act is not unlawful, it matters little with what motives a person commits it or the consequences; he is outside the law, i.e. criminal law; civil law might have a remedy, but criminal law does not. Even when a criminal offence is committed, it may contain ingredients without which, what would otherwise be a punishable act, becomes guiltless. Most qualifications to guilt are of longstanding, used by parliamentary draftsmen in a wide range of statutes and have acquired reasonably precise judicial meaning. Most relate to intention—wilfully, intentionally, knowingly—and in a few, judicial extension of the popular meaning and usage of the term has occurred to prevent an innocent stance being simulated by a guilty party. “Knowledge” is such an example. The term has been deliberately widened to cover persons who “shut their eyes” to an offence; where a person deliberately refrains from making enquiries, the results of which he would not care to know, this amounts to having such knowledge— constructive knowledge.

The purpose of this paper is to consider how to couple and quantify resilience and sustainability, where sustainability refers to not only environmental impact, but also economic and social impacts. The way a particular function of a building is provisioned may have significant repercussions beyond just resilience. The goal is to develop a decision support tool for facilities managers.

A risk framework is used to quantify both resilience and sustainability in monetary terms. The risk framework allows to couple resilience and sustainability, so that the provisioning of a particular building can be investigated with consideration of functional, environmental, economic and, possibly, social dimensions.

The method of coupling and quantifying resilience and sustainability (CQRS) is illustrated with a simple example that highlights how very different conclusions can be drawn when considering only resilience or resilience and sustainability.

The paper is based on a hypothetical example. The example also illustrates the difficulty in deriving the costs and probabilities associated with particular indicators.

The method is generic, allowing the method to be customized for different user communities. Further research is needed to translate this theoretical framework to a practical tool for practitioners and to evaluate the CQRS method in practice.

The intention of this research is to fill the gap between the need for increasing sustainability and resilience of the built environment and the current practices in property maintenance and operation.

The paper aims to assess two sustainability metric methodologies, material flow analysis (MFA) and integrated sustainable cities assessment method (ISCAM), as applied practically to an Irish settlement, in order to compare utility and transparency for stakeholders and policy makers.

Both methods were applied to an Irish settlement, namely Tipperary Town, with MFA measuring efficiency of resource usage, as measured by urban metabolic efficiency, and the ISCAM method simulating alternative scenarios as well as calculating the divergence or otherwise of current or business as usual (BAU) trends from more sustainable scenarios.

It was found that both methods have high data requirements, presenting a need for proxy analysis and disaggregation, with the ISCAM method requiring data functionally matched to a time series and over a long time framework. The ISCAM method may also require more advanced extrapolation methods than the simple linear extrapolation employed in the analysis for statistical robustness to reflect behaviour modes more complex than the deterministic behaviour assumed for the selected indicators. A material flow analysis (MFA) was undertaken for household food and waste and it was found that there was a high metabolic efficiency.

This paper was restricted to an application of two methodologies by time constraints and thus was unable to appraise a more comprehensive range of sustainability appraisal options, for example, ecological footprints.

It applies novel methodologies in an Irish context, further highlights the need for more sustainable policy development in an urban setting and was aimed at policy makers at national and local levels.
