This paper presents a sustainability assessment model to holistically guide sustainable construction and green retrofitting of affordable housing from the Ghanaian perspective.

A comprehensive review was carried out, which yielded 16 sustainability indicators. Then, a questionnaire survey was conducted among respondents in the Ghanaian housing sector. Forty-seven valid responses were received and analysed using fuzzy synthetic evaluation (FSE) technique.

A four-index model was developed that includes: Housing and Transportation (H + T) index, household-satisfaction index, efficient stakeholder-management index and quality-related index. These indices account for 25.3%, 26.3%, 23.6% and 24.9% of sustainability attainment in affordable housing, respectively. Accordingly, household-satisfaction has the greatest contribution to sustainability attainment in affordable housing.

Due to challenges in obtaining responses to the questionnaire, the study was conducted with relatively small number of responses.

The model serves as a tool that could be used to objectively and comprehensively assess sustainability performance in affordable housing. Besides, it could be used as a baseline to calibrate future projects and for benchmarking success levels of comparable housing projects. Finally, the estimated indices are applicable in decision making for optimum resource allocation for sustainable low-cost housing in the Ghanaian perspective.

The purpose of this study is to identify crucial sustainability assessment criteria in the context of international port sector.

Data collection was based on a questionnaire survey from 135 managers and supervisors at major international ports in Taiwan, including Keelung, Taichung and Kaohsiung. A confirmatory factor analysis was conducted to identify crucial sustainability assessment criteria at ports.

A total of 31 important sustainable assessment criteria were adapted from previous studies in terms of environmental, economic and social issues. Results revealed that social issues with respect to staff job security and safety were ranked as the most important sustainability assessment criteria, followed by environmental protection when handling cargo, facilitation of economic activities, port traffic accidents prevention and cargo handled safely and effectively. In contrary, respondents revealed their less importance in the criteria, namely, mitigating light influence on neighboring residents, considering the arrangement of vehicles when constructing port transportation system, avoiding using unpolluted land in port area and hiring minority groups and consulting interests groups when making port projects. Four sustainability assessment dimensions were identified, namely, environmental material, economic issue, environmental practices and social concerns.

The research findings indicated that economic issue was deemed as the most important dimension of sustainability assessment criteria from a port operator’s perspective, followed by environmental practices, social concerns and environmental material. Practical implications for port sustainability assessment were discussed in this research.

Although a majority of previous studies on sustainability assessment have been discussed, there is still a lack of investigation of sustainability assessment in the context of port sector. This study not only develops sustainability assessment attributes but also highlights the important criteria of sustainability assessment. Further, this study identified four crucial sustainability assessment factors, which provide helpful information for port corporations to identify important criteria and policy of sustainability assessment.

In light of the lack of subjective criteria and scientific rationality in current sustainability performance assessment, the purpose of this paper is conducted to improve the sustainability performance assessment of high-tech firms by developing a hybrid approach that integrates quantitative and qualitative research methods.

This study proposed a hybrid approach that integrates word frequency analysis, cluster analysis, grey theory and the decision-making and trial evaluation laboratory (DEMATEL) method. Specifically, this study identifies useful criteria using quantitative word frequency analysis as well as qualitative literature research. Then, cluster analysis is used to divide these criteria into different categories. Subsequently, this study applies the grey theory associated with the DEMATEL method to assess the sustainability performance of high-tech firms.

The results reveal that the socio-environment is an important aspect underlying the corporate sustainability performance of high-tech firms. Therefore, high-tech firms should enhance their pollution emission control capabilities and increase investment in energy-conservation and emission-reduction technologies to drive sustainable development. In addition, increasing green product sales revenue and improving the guiding capability of green consumption are core issues that firms must address.

This study assesses the sustainability performance of high-tech firms by applying a hybrid method. This method can be used to construct a framework for scientific sustainability performance assessment and to provide a clear direction for the sustainable development of firms.

The purpose of this paper is to present the development of an action and assessment framework to make sustainability in German facility management (FM) transparent, measurable and assessable.

The underlying research project’s approach to develop the new action and assessment framework consisted of a three-step methodology: to define and substantiate sustainability in FM, to operationalise and quantify sustainability in FM and to validate the developed system draft through an initial pilot study.

The main result of the presented research project is a set of 24 criteria, organised into the separate areas of environmental, economic and sociocultural quality, as well as the quality of FM organisation and the sustainability of building/contract-specific facility services. The assessment methodology reflects the strategic approach of a plan–do–check–act loop to create a transparent and objective appraisal and a practical action framework.

The outcome of the study is initially only a measurement and assessment framework. To transform the finalised system draft and assessment tool into a certification system, further steps of development are necessary.

The newly developed action and assessment framework is able to cure the blind spot that the relevant players (building owners, users and service providers) suffer from while developing, purchasing and comparing concepts for sustainable FM. The results and practical experiences of its initial pilot study show that this new framework can make the building operation phase and its processes transparent, measurable and assessable.

The guideline is also able to establish a crucial basis for the development of corporate sustainability strategies and sustainability reporting. This is an important step in closing the existing gap in numerous corporate social responsibility reports.

Due to its assessment methodology and the calibration of its criteria, this new action and assessment framework both diversifies and completes the range of existing sustainability certification systems.

The purpose of this research is to focus on the evaluation of heritage buildings' sustainability. BIM modeling was necessary for the design of the sustainability assessment model for Heritage Buildings (SAHB). Using ArchiCAD®, energy simulations were performed for two case studies (Murabba Palace, Saudi Arabia, and Grey Nuns Building, Canada), and the developed model was validated through sensitivity analysis.

Heritage buildings (HBs) are unique and must be preserved for future generations. This article focuses on a sustainability assessment model and rating scale for heritage buildings in light of the need for their conservation. Regional variations were considered in the model development to identify critical attributes whose corresponding weights were then determined by fuzzy logic. Data was collected via questionnaires completed by Saudi Arabian and Canadian experts, and Fuzzy TOPSIS was also applied to eliminate the uncertainties present when human opinions are involved.

Results showed that regional variations were sufficiently addressed through the multi-level weight consideration in the proposed model. Comparing the nine identified factors that affect the sustainability of HBs, energy and indoor environmental quality were of equal weight in both case studies.

This study will be helpful for the design of a globally applicable sustainability assessment model for HBs. It will also enable decision-makers to prepare maintenance plans for HBs.

The neighbourhood sustainability assessment frameworks through which a proposed neighbourhood development can be evaluated against an array of sustainability indicators began to gain prominence in the first decade of the twenty-first century. However, how these frameworks align with the Bellagio STAMP is an area yet to be examined by existing studies to inform their better development and usage in the delivery of sustainable neighbourhoods. The purpose of this paper is to review selected neighbourhood sustainability assessment frameworks using the Bellagio STAMP with the aim of identifying areas for improvement, while also exploring the possibilities of adopting the Bellagio STAMP as a consensus approach and reference to sustainability assessment at the neighbourhood level.

Adopting document analysis as a data collection method, the paper reviews BREEAM communities, LEED Neighbourhood Development, Pearl community rating system and Green Star communities using the Bellagio STAMP.

Findings from the study revealed that some of the selected assessment frameworks align partially with the Bellagio STAMP in their development, while areas for improvement were identified.

The study recommends that the Bellagio STAMP could offer helpful guidelines and procedure in conceptualising sustainability assessment at the neighbourhood level especially in developing countries where such a framework is yet to be conceived.

This study adds to the sustainability assessment literature by operationalising the Bellagio STAMP leading to its better understanding and application in sustainability assessment either in practice or in theory.

The paper aims to present the core part of the research work done within the FP7 OPEN HOUSE project, aiming to merge existing methodologies for sustainability assessment of buildings towards a common view, applicable as an open access assessment method across European Union (EU). One of the principle tasks was to evaluate the applicability of proposed indicators in EU countries with different legal frameworks, climate conditions, status and condition of the building stock and construction tradition.

To reach the goal, it had to be established first whether the pre-selected indicators suit the purpose in countries different from each other regarding various influential factors. A questionnaire survey based on close-ended quantitative thematic questions was performed to evaluate the acceptability and relevance of each indicator in national contexts, thus defining the path for the final protocol of selection criteria for the OPEN HOUSE method.

The responses enabled and justified necessary minor corrections and regrouping to define the full (56 indicators) and core (30 indicators) indicator sets, demonstrating that the system is applicable in EU countries. This task made ground for finalisation of the OPEN HOUSE method: definition of evaluation procedures and sustainability performance levels and testing of the approach on demo cases.

This paper shows how the research team tackled the problem of limited use of building sustainability assessment methods due to specific boundary conditions by determining a widely applicable set of categories and related indicators based upon an extensive analysis of existing assessment methods, standardisation development, formal guidelines and strategic (inter)national frameworks.

The purpose of this paper is to provide a framework to assess the sustainability of service supply chains (SC) based on the concept of the balanced scorecard and three dimensions of sustainability, namely economic, social, and environmental performance.

After reviewing the literature and interviewing the experts, the preliminary list of identified general criteria is categorized in the four perspectives. Then, to select the most important factors in hospital SC, 15 experts evaluated the identified criteria by questionnaires of Fuzzy Delphi Method. Then, interpretative structural modeling was applied to identify the interrelations between the perspectives and between the criteria.

The framework includes four perspectives, financial; service SC operations; stakeholders’ satisfaction in the direction of sustainability; and learning, growth, and innovation, to improve the SC for sustainability in the service industry. According to the results, the identified criteria are interrelated.

The paper provides an important reference to assess the sustainability of service SCs. It will be beneficial in strategic and operational decision-making in service industries.

Reviewing the literature shows that the concept of sustainability of service SCs is still immature. The paper is a preliminary effort to identify the general criteria of sustainability and their interrelations in the service sector. The presented general framework links the financial measures with the environmental and social measures. It helps to maintain the balance between the sustainability goals for the service SC managers. It can be modified and applied in different service sectors.

Purpose: Urban centres have been argued to be crucial in the battle for sustainability. With more than half of the global population presently living in cities, the sustainability challenges of global warming, environmental degradation, social inequality, and economic recessions have continued to thrive. To this end, there have been efforts to revive and improve the existing physical and social structure of cities in a process known as urban regeneration. The aim of this paper is to explore the role of sustainability assessment frameworks in urban regeneration.

Approach: Aligning with the positivism philosophical position, and using document analysis as a data collection method, the study discusses the state of the art of urban regeneration and its application in recent times. The study also reviewed selected neighbourhood sustainability assessment frameworks as a tool for decision-making towards sustainability to know the extent in which they capture the goals of urban regeneration.

Findings: Findings showed that the uptake of the sustainability assessment frameworks could play a role in enhancing integration of local context, social wellbeing and economic prosperity, environmental quality, and stakeholder engagement at the neighbourhood level which are the main aspects of urban regeneration.

Theoretical and practical implications: In theory, this paper establishes the assumption that with some revisions, sustainability assessment frameworks could serve as a tool for decision-making in urban regeneration process. Practise-wise, urban regeneration at the neighbourhood level can now be measured against sustainability benchmarks and indicators.

The purpose of this study was to explore strategies used by developers of master-planned housing development projects in Victoria, Australia, for obtaining certification under the Urban Development Institute of Australia’s (UDIA) EnviroDevelopment (ED) sustainable development certification programme. To be awarded ED certification, a development must demonstrate that it meets the assessment criteria within at least four of the six ED “leaves”. These leaves relate to its performance in terms of energy, water, materials, waste, community and ecosystems. This study explored how developers make choices regarding sustainability features they build into the planning, design and management of their developments to gain the leaves needed for ED certification. Having this certification is valued by developers as it can be used to demonstrate the sustainability credentials of their developments to potential house buyers, the validity of which is backed up by a trusted independent non-profit organisation (UDIA).

The study sought to quantify the preferential weightings of nine developers in selecting ED “leaves” and the strategies they use for meeting the assessment criteria needed to obtain selected ED leaves. This was done using a novel data collection and analysis method, the analytical hierarchical process (AHP), which relies on respondents, in this case, developers of ED certified development projects, making pairwise comparisons between choices of different development factors associated with the different ED “leaves”.

The most highly preferred ED leaves were found to be community, energy and ecosystems. “Community facilities” and “on-site transportation” were the two most highly weighted factors associated with the community leaf. Energy, the next most preferred leaf, was most highly weighted on “saving on operational costs” for the consumers (home buyers). Here consumer demand factors seem to be driving preferences. The ecology leaf was the next most preferred, with “existing site conditions” being the most highly weighted factor for this leaf. For sites that already contain significant areas of indigenous habitat, such as wetlands, selecting this leaf would seem to be an attractive, and potentially lower cost, option. Existing ecologically significant natural areas that are preserved, and where necessary enhanced, can be used for marketing purposes and serve in fulfilling planning open-space contribution requirements. The developers were more indifferent to the water, waste and materials leaves; however, the water leaf was rated slightly higher than the other two and was most strongly associated with “recycled water” and opportunities for “water conservation”, another example of demand factors driving preferences.

The results of this study reveal the preferences of a small sample of developers in terms of how they weigh different factors in making decisions about acquiring sustainability certification for residential master-planned development projects through the UDIA’S ED programme. The findings provide insight into the types of decisions developers make in the process of seeking ED certification, which includes considerations of site characteristics, costs, predicted effectiveness of different interventions and usefulness for marketing and other factors in terms of which ED leaves to pursue and how to acquire them to gain ED certification. The study also tested the AHP method as a methodological tool for addressing this question. Modifications in how data are collected using the on-line survey can be made to allow the method to be more easily used with larger respondent sample sizes. Collection of more focussed data elicited from respondents with specific areas of expertise, for example, specialists in energy, water, landscape architecture and planning, ecology and other relevant areas of knowledge, should also been considered.
