Abstract

Purpose

Sustainable urbanism is the study of both cities and the practices to build them, which focusses on promoting their long-term viability by reducing consumption, waste and harmful impacts on people and place while enhancing the overall well-being of both people and place. This paper analyses the implications of adopting sustainable urbanism principles and developing resilient places with Abuja as the area of focus to tackle the highlighted issues.

Design/methodology/approach

The paper is based on qualitative research which is centred on an extensive literature review and archival retrieval of historical documents. This includes the emergence of urbanism, sustainable urbanism definition and current issues surrounding its adaptation. The paper also focusses on a case study area in the capital city of Abuja, Nigeria which is currently undergoing massive urban development. Interviews are conducted with academics (13), practitioners (12) and government officials (10) making a total of 35 participants.

Findings

The main findings will create an understanding of the definition of sustainability and sustainable urbanism with a special focus on Abuja city. It was realised from the interviews that sustainable urbanism in broad terms encompasses economic, social, and environmental sustainability, and that these dimensions vary across different contexts even in the developing world. Also, sustainability can be achieved through deploying the right combination of measures, policies, assessment tools, sustainability assessment, good governance, and training/education and incentives.

Originality/value

By reviewing the selected studies which explore a wide range of disciplines and research areas, and conducting this qualitative research, this paper shares insights into how sustainability and sustainability urbanism can be achieved in the development of urban spaces in Abuja environs.

Abstract

Purpose

The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate.

Design/methodology/approach

This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis.

Findings

This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings.

Originality/value

This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.

Abstract

Purpose

Against the backdrop of the changing trends in tenure in the UK housing system, young adults are faced with different situations that continue to shape their housing consumption and decisions. The purpose of this paper is to investigate the relationships amongst young adults’ housing tenure, social capital and elements of perceived job security in Britain. Socio-psychological dimension of housing tenure decisions has been receiving attention by housing market analysts and practitioners seeking deeper understandings of the UK housing market dynamics, particularly in the wake of changing tastes and preferences of young people concerning housing decisions across major cities of the world.

Design/methodology/approach

A quantitative approach has been applied to the harmonised version of the British Household Panel Survey (BHPS) from 2001 to 2015.

Findings

The authors discovered that British young adults’ homeownership decisions are increasingly influenced by social capital and elements of perceived job insecurity, depending on their tenure of origin. Furthermore, this study will significantly enhance the understanding of tenure shifts amongst young adults in the UK and provide property developers, local authorities and central governments the knowledge and information to guide economic policies, urban renewal towards achieving better social cohesion and sustainable communities.

Originality/value

Very little has been done to investigate the contributions of social capital formation, for example, neighbourhood or social integration and social relations and elements of perceived job security on housing tenure transitions among British young adults. This study will further provide property developers, local authorities and central governments the knowledge and information to guide economic policies, urban renewal towards achieving better social cohesion and sustainable communities.

Abstract

Purpose

A major challenge for foreign lenders in financing public private partnerships (PPP) infrastructure projects in an emerging market (EM) is the bankability of country-related risks. Despite existing studies on country risks in international project financing, perspectives of foreign lenders on bankability of country-specific risks in an EM is yet to be explored. Hence, using a mixed methodology approach, three private finance initiatives/PPP projects in Sub Saharan Africa (Nigeria) were used to investigate political risk, sponsor, concession and legal risks in PPP loan applications. The paper aims to discuss these issues.

Design/methodology/approach

The study adopted mixed methodological approach comprising focus group discussions and analysis of loan documents obtained from foreign project lenders, in addition to the questionnaire survey distributed to local and international project financiers with experiences in PPPs within Nigeria.

Findings

Results identified seven topmost bankability criteria for evaluating country-related risks (political risk, sponsor, concession and legal risks) in EM PPPs. In addition, a “Risk and Bankability Framework Model” was developed from the study presenting critical parameters for gaining foreign funding approval for EM’s PPP loan applications.

Research limitations/implications

Since the study only explored bankability of PPPs in Sub Saharan Africa with the exclusion of other geographical regions, the proposed framework model should be taken in context of EMs as a mind-map for foreign lenders and local private investors seeking to finance PPPs in an EM.

Practical implications

Results from the study represent critical parameters for winning foreign loan approval for PPP infrastructure projects within an EM context.

Originality/value

Study proposed “Risk and Bankability Framework Model” relevant for evaluating PPP loan applications at the pre-approval stage for EM PPPs.

Abstract

Purpose

The UK construction industry produces up to one third of all waste to landfill. This study aims to identify specific project practices impeding the reduction of waste in construction projects as well as uncovering potential waste solutions throughout the project delivery process. The rationale being that for such a drastic reduction in waste to landfill, holistic and extensive measures would be required.

Design/methodology/approach

A two‐way methodological approach was used. This comprised qualitative unstructured interviews and a quantitative questionnaire survey of three major stakeholders in the UK construction industry: clients, architects and contractors.

Findings

Design factors remain the major cause of impediments to waste reduction to landfill. Critical impediments include clients making waste prevention a top priority in projects, overly complex designs, waste taking a low priority compared to project time and costs, lack of concerns by designers for buildability, among others. Critical solutions include early supply chain involvement in design process, choosing materials for their durability, early communication of design changes to all parties, longer project programmes and better lead times, among others.

Practical implications

In all, the target of halving construction waste to landfill based on the 2008 benchmark is achievable but would require construction companies to take it upon themselves to implement the proposed solutions suggested by this study.

Originality/value

The value of this research is to provide UK construction companies with solutions to reduce waste and aid the reaching of the landfill target, as landfill is decreasing as a solution to waste. In addition the cost savings on reducing waste could be crucial for companies in this current economic climate.
