Although a basic need, housing and its development activities impinge on the environment. As part of efforts to promote sustainability, there have been several initiatives since the Brundtland Commission's work in 1987 to minimise the adverse impact of housing development activities on the environment in the developing world such as sub-Saharan Africa (SSA). This chapter explores housing development activities in Ghana within the context of environmental sustainability based on the extant literature. The aim is to examine the state and promotion of environmental sustainability in the housing development sector. The chapter establishes that although there are some efforts to promote environmental sustainability within the housing development sector, uptake of environmental sustainability practices has been less satisfactory due to lack of incentives as stakeholders perceive that environmentally sustainable homes are more expensive than conventional ones. The chapter, therefore, recommends further investigations into the cost and benefit of environmentally sustainable homes as well as other drivers in Ghana to give additional insights to provide the appropriate doses of incentives both contrived and instinctive to drive uptake.

This study¹ seeks to identify and propose a model for measuring and assessing the level of sustainability in housing environments based on a range of indicators. With this intention, the article is composed of four main parts. In the first part, the relationship between sustainability and housing is presented based on previous research; in the second part, a theoretical framework is put forward for sustainable housing. Then in the third part, sustainability indicators are discussed thoroughly within the context of indicator frameworks. In this section, the development, selection and measuring processes of indicators are also introduced. Finally in the fourth part, the model for measuring and assessing the level of sustainability in housing environments is presented. It is believed that this model will be used as a tool in the decision-making processes for the future development of existing housing settlements and their environments.

The purpose of this paper is to assess the selection and use, in practice, of appraisal frameworks regarding sustainability evaluation in UK social housing sector projects, which have been advocated by academics as a means of ensuring that business decisions related to potential built environment projects are driven by best value rather than lowest cost. It also seeks to identity the key features of sustainability as assessed at the project feasibility stage. The research context is housing regeneration projects undertaken by UK social housing providers.

Using a quantitative approach, a survey was conducted of 481 built environment professionals working within the UK social housing sector, which generated an overall response rate of 24 per cent.

The survey results revealed that few toolkits and models developed by academe to facilitate the development and evaluation of sustainability-led building projects have so far been adopted. The impact of organisational factors such as size, denomination, and maturity on the frameworks was analysed and, in general, no statistically significant relationship was found between organisational features and the models in use. The principal features of sustainability were found to be related to energy efficiency and asset life expectancy. These findings have implications for the UK construction industry’s commitment to enhancing the built environment’s sustainability and thereby stakeholder prosperity.

The methodological approach adopted failed to uncover fully the reasons why practitioners selected particular types of sustainability appraisal toolkits.

This paper focuses on the current use of sustainability-led project appraisal models and the key features of sustainability whilst also providing directions for further research. It explores the adoption of sustainability-focused project evaluation practices in the UK social housing sector and outlines potential areas for further research, focused on developing a usable, holistic framework for evaluating sustainability during the early stages of project development to help to create a more sustainable built environment.

The paper contributes to the body of knowledge available on the adoption of sustainability-focused project evaluation practice in the UK social housing sector, outlining potential areas for further research, focused on developing a usable, holistic framework for evaluating sustainability during the early stages of project development to help to create a more sustainable built environment.

The challenges of providing housing that sustains its inhabitants socially, economically and environmentally, and is inherently sustainable for the planet as a whole, requires a holistic systems approach that considers the product, the supply chain and the market, as well as the interdependencies within and between each of these process points. The purpose of the research is to identify factors that impact the sustainability performance outcomes of residential dwellings and the diffusion of sustainable housing into the mainstream housing market.

This research represents a snapshot in time: a recording of the experiences of seven Australian families who are “early adopters” of leading edge sustainable homes within a specific sustainable urban development in subtropical Queensland. The research adopts a qualitative approach to compare the goals and expectations of these families with the actual sustainability aspects incorporated into their homes and lifestyles.

The results show that the “product” – a sustainable house – is difficult to define; that sustainability outcomes were strongly influenced by individual concerns and the contextual urban environment; and that economic comparisons with “standard” housing are challenging.

This qualitative study is based on seven families (13 individuals) in an Ecovillage in southeast Queensland. Although the findings make a significant contribution to knowledge, they may not be generalisable to the wider population.

The experiences of these early adopter families suggest that the housing market and regulators play critical roles, through actions and language, in limiting or enhancing the diffusion of sustainable housing into the market.

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.

Sustainability Declarations were introduced by the Queensland State Government on 1 January 2010 as a mandatory disclosure measure for all dwelling sales in the State. The purpose of this paper is to assess the impact this policy decision has had in the homebuyer decision‐making process in the first year since its introduction and to consider the effectiveness of the legislation in meeting its policy objectives.

This quantitative research comprised a two‐part process: the first stage surveyed the level of compliance by the real estate industry with the legislative requirements. Stage two comprised an online survey of Real Estate Institute of Queensland members to determine what impact the Sustainability Declaration has had on home buyer decision making and how effective the legislative mechanisms have been in achieving the policy objectives.

This paper assesses the initial impact of this initiative over its first year in operation. These preliminary findings indicate a high level of compliance from the real estate industry, however results confirm that sustainability is yet to become a criterion of relevance to the majority of homebuyers in Queensland.

These quantitative findings support anecdotal evidence that the objectives of the legislation to increase homebuyer awareness and relevance of sustainability issues in the home are not being achieved.

Sustainability Declarations are a first step in raising homebuyer awareness of the importance of sustainability in housing. Further monitoring of this impact will be carried out over time.

This is the first research undertaken to assess the impact of this new mandatory disclosure legislation in Queensland, Australia. The findings will inform policy makers and assist them to assess the effectiveness of the current legislation in achieving its policy objectives.

The intervention of many different organizations during the post-disaster housing reconstructions could also influence the sustainability of the overall socio-ecology of the affected areas. Different approaches in design, selection of building materials and construction technologies deployed in pursuit of disaster resiliency may cause undesirable adverse circumstances to the surroundings, which escalate its susceptibility to future calamities. Therefore, this paper aims to identify relevant key indicators which interpret construction sustainability in a post-disaster housing reconstruction context, and to further investigate the dynamic interactions of these indicators on the socio-ecological system to achieve holistic sustainable post-disaster housing reconstructions.

Methodology was divided into three main stages. The first stage involved content analysis of related research materials, whereas the second stage was allocated for empirical data collection from case study and interview sessions. Data obtained from the first and second stage were then used to develop a causal loop diagram in the third stage to identify dynamic interrelationships between the indicators and the variables within a post-disaster reconstruction system.

From our results, the nexus of sustainability and disaster resilience is apparent and it is imperative to comprehend their dynamic interactions. The impacts of post-disaster reconstructions on the socio-ecological system are significant. Therefore, the adaptation of integrated sustainable construction approach in the housing reconstruction practice through system thinking will foster a holistic approach in the decision-making process and could reduce environmental damage. This also strengthens the interrelated socio-ecological systems, thus reinforcing disaster resilience in the built environment.

This research looks into the adaptation of integrated sustainable construction approach in the housing reconstruction practice through systems thinking approach. This will foster a holistic approach in the decision-making process and could reduce environmental damage. This also strengthens the interrelated socio-ecological systems, thus reinforcing disaster resilience in the built environment. This paper also looks into identifying relevant key indicators that interpret construction sustainability, which incorporate environmental, social and economic factors pertaining to the context of post-disaster housing reconstruction in Kuala Krai, Kelantan. The dynamic interrelationships and causal impacts between the indicators with other variables within the system were also established.

The purpose of this paper is to enhance sustainability in affordable housing in Saudi Arabia within an effective locally adopted sustainability assessment tool by discussing the multi interdisciplinary concept of sustainability in the built environment and introducing environmental indicators which are recently developed to foster environmentally responsible practices. The study aim expands beyond proposing sustainable feasible alternatives for existing affordable housing project in Saudi Arabia, namely, Al-Ghala project, to appropriating the measuring tool itself to make the review process easier, faster and more effective.

Al-Ghala project, a typical affordable housing project is selected to act as a case study for this research. The housing units are assessed according to LEED to obtain the overall evaluation which obviously reflects the quality of the project sustainability. Elements that negatively affect the score and suggested feasible remedies are then identified, as well as inapplicable and inappropriate LEED components. The data were complemented by observation, interviews with occupants and project management team, monthly consumption rates of water and electricity, in addition to computer modelling and analysis by Ecotect and Green Building Studio.

Sustainability in affordable housing requires a holistic framework that promotes environmentally responsible practices including design, construction and management phases. LEED provides evidence that it can considerably contribute in enhancing sustainability of post-occupied affordable housing units by identifying points of weakness that lead to inefficient use of energy, water and materials; paving the way for a wide range of sustainable modifications. In addition, for LEED to be competent in Saudi Arabia a native version needs to be developed in which local circumstances are taken into consideration.

According to the wide range of subjects covered by LEED, some elements could not be measured in depth. Impact of modifications proposed for LEED needs to be tested further.

The paper includes implications for the development of feasible environmentally sensitive affordable housing in Saudi Arabia.

This paper fulfills an identified need to study how affordable housing can be made sustainable.

The purpose of this paper is to attempt to bridge the gap between sustainable housing and the use of smart technologies to improve the level of sustainability in the housing construction in Saudi Arabia, by discussing the barriers and enablers concerned with applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies.

A Delphi method survey was employed, for which 25 individuals from three key stakeholder groups of the Saudi housing sector participated. They were asked about their degree of agreement (or disagreement) about the various barriers and enablers of applying sustainability to housing construction in Saudi Arabia, which utilises smart technologies. This research paper must be considered as an indicative study of selected experts that do not represent in any way the total population of Saudi Arabia.

Lack of public awareness has been identified as the most significant barrier in implementing sustainable housing development in Saudi Arabia, which utilises smart technologies. Raising awareness of the public to the benefits of sustainable housing and enlightening key project stakeholders in the design of sustainable housing are both essential in order to overcome the barriers discussed in this paper. In addition, it is important to adopt smart sustainable construction methods, exemplified by but not limited to, appropriate water preservation and wastewater treatment systems that are simultaneously smart and sustainable.

This particular research has dealt with only barriers and enablers in the application of sustainability to housing in Saudi Arabia, which utilises smart technologies. For a more complete understanding, there is a need for further analysis of supplementary factors.

A study such as this, which identifies and prioritises barriers and enablers, could prove useful in guiding or encouraging the relevant ministry in Saudi Arabia to develop policies founded in the implementation of sustainability to the housing sector.

This research is a preliminary investigation into the implementation of sustainable housing development as it relates to Saudi Arabia.

Housing delivery systems have been classified as developmentally‐orientated or conventionally‐orientated. It has been claimed that a developmentally‐orientated approach to building procurement would encompass the parameters of community empowerment and participation in design, job creation via the development process, and economically and environmentally‐sustainable procurement (Taylor & Norval 1995). New building procurement systems display an increasing awareness of sustainability, but concentrate on economic and social sustainability, as opposed to environmental sustainability. The purpose of this paper is to document and evaluate the extent to which issues of environmental sustainability have been incorporated in the delivery of affordable housing in South Africa. The paper elaborates on a range of relevant principles for sustainable construction, which incorporate: minimisation of resource use; maximisation of reuse of resources; maximisation of use of renewable and recycled resources; use of non‐toxic materials; protection of nature; achievement of quality criteria; and promotion of labour intensive methods, skills training and capacity enhancement of local people. The authors examine the extent to which the principles of environmental sustainability have been applied, both in practice and in the formulation of South African housing policy. Finally, recommendations are made for the application of criteria for environmental sustainability in the delivery process of affordable housing in South Africa.
