This study aims to explore the concept of green building by determining a suitable system for categorising green building features (GBFs) that are considered significant in enhancing the value of a building in a developing economy with particular reference to South Africa. The motivation for categorising the features is based on the perception that the upsurge in adopting green building and sustainability has ushered in a new and formidable set of challenges to practising professionals in terms of recognising the most significant value-adding GBFs.

A quantitative approach was adopted, involving randomly selected construction professionals within the Western Cape Province of South Africa. The data were analysed using descriptive and inferential statistical analysis tools.

Based on the mean ranking analysis, the top three most important features, amongst others, were kitchen and water-closet (WC) water efficient fittings, megawatt photovoltaic solar plant and water metering for monitoring and leak detection. Additionally, an exploratory factor analysis revealed that the underlying grouped features were “recycled materials and high-performance building energy design”, “water-saving and solar technologies”, “biometric system and acoustical feature”, “sensor control and natural daylight design”, “daylight harnessing feature”, “high-performance hydrologic strategy and noise control feature” and “special utility feature and water efficiency technologies”.

This study was conducted and limited only to the Western Cape Province of South Africa. However, the findings have practical significance to the generality of green building projects and may serve as a useful guide for other developing countries.

This study broadens the viewpoint of construction professionals to recognise and prioritise the most important GBFs in South Africa that increase the value of a building. To create a system for assessing the sustainability of a building, the seven components and the features associated with them may be useful.

The purpose of this paper is to investigate the extent to which green building features are evident in office properties in Lagos, Nigeria; and consequently determine the degree of compliance with green standards in the country.

The study purposively sampled two (2) office properties from the management portfolio of 88 registered Estate firms in Lagos. Data were collected using physical observation on the properties and interview with two users purposively selected from each of the properties. The data were analysed with the use of frequency distribution, percentages and measures of green features availability index.

The result revealed a low extent of green features incorporation in existing office properties with the value of availability indices on most features falling below 2.5 on a five-point scale. Feature relating to material use and conservation is the most incorporated green feature (mean score of 2.62) while those relating to owner and occupant education were least in incorporation (mean score of 1.895).

From the findings, it is apparent that green retrofitting may be necessary in Nigeria due to the low extent of green practices in existing office properties. Also, reinforcement of existing government policies and increased sensitisation of stakeholders on impact of current building practices are pertinent to green building success in Nigeria.

Most existing studies of similar focus are based in the developed economies where stronger implementation framework exists for green building. Besides, they are mostly based on evaluation of green certified buildings using few criteria. This study differs in that it presents the existing building sustainability practices in a less pronounced green property market, with varying architectural styles using more robust criteria. Information provided is applicable in Nigeria and other emerging economies.

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.

The purpose of this paper is to investigate the degree of willingness of property developers to invest in green features in Abuja, the federal capital city of Nigeria, to determine the level of their preparedness for green building development.

Data were elicited from the property managers of the various property development companies through self-administered questionnaire and analyzed with the use of frequency distribution, percentages and measures of developers’ willingness to invest index.

The study showed that the developers’ level of willingness to invest in green features is above average with the value of willingness indices on most features rising above 2.5 on a five-point scale. Features that are less capital intensive such as “Location of air intake that are far from source of pollution” (RWI = 4.14) and “Building design that utilize natural and cross ventilation” (RWI = 4.12) attracted higher developers’ level of willingness than features such as “Mechanical ventilation of enclosed parking area” (RWI = 2.15) and “Design for energy efficient deconstruction and recycling” (RWI = 1.84) that are more capital intensive. In addition, the index of willingness (relative willingness index of developers) on features that are associated with occupants’ comfort is higher than the index of willingness on features that confer more of environmental benefits.

The study concludes by advocating that parliamentary arms of all tiers of government should formulate environmental policies and laws that will entrench sustainable practices in the building industry in the country.

This is one of the few studies on the willingness of major stakeholders to invest in green features, particularly in the Nigerian context.

The purpose of this paper is to identify the perception of valuers towards the contribution of green features in residential property valuation. The concept of green housing was designed to reduce the negative impacts on the environment and humans. The cost of green housing is higher than the conventional building and is reflected in the selling price, which is further enhanced by the increasing demand for green buildings in the housing market. Such a scenario could be a challenge to the valuers when they carry out a valuation on housing with green features, as there is a lack of information to guide valuers.

This study used a quantitative research method. A comprehensive review of the international green rating tools was carried out to ascertain the relative green features in residential buildings. There are 14 green features identified and grouped into four main categories. A total of 147 valid responses were collected by an online platform and face-to-face distribution among licensed valuers in Malaysia.

The result confirmed that the 14 green features are contributing to the residential property valuation with a reasonable range of adjustment from 2.0% to 6.5%.

The understanding of the range of adjustment for each green feature may provide a guide to the valuer in determining the range of adjustment based on green features associated with residential property in Malaysia. The findings contribute ideas and options to the future development of residential projects by taking into consideration the specific green features that potentially lead to environmental sustainability and building value.

The purpose of this paper is to examine the preference of office property users for green features in Lagos, Nigeria. This is with a view to determining the degree of users’ aspiration for green buildings in the country.

The study purposively sampled two office properties from the management portfolio of 88 registered estate firms in Lagos. Data were collected using self-administered questionnaire on two users purposively selected from each of the properties. The data were analyzed with the use of frequency distribution, percentages and measures of the users’ preference index.

The results revealed that the preference for green features by office property users in the study area was above average (2.5 on a five-point scale). Feature relating to “building ecology, waste and recycling” is the most preferred feature with UPI of 3.970 while those relating to “owner and occupant education” with UPI of 3.558 were least in preference.

The paper concludes that with the preference of users for green features in the study area, it may be necessary for government to strengthen the existing framework for sustainable development. Also, increased sensitization of investors, users, professionals and other stakeholders in the building industry is pertinent to the success of green building practice in the country.

This is one of the few studies on users’ preference for green features in emerging economy, particularly in the Nigerian context.

The health, well-being and productivity (i.e. WELL) of office building occupants are vulnerable to poor office environments. Therefore, this study aims to identify new features and concepts of office buildings in supporting occupants’ WELL. To achieve that aim, this study: explores new WELL features for office buildings, develops new WELL concepts for office buildings and examines the influence of the newly developed WELL concepts on existing WELL building standard (WELL v2) concepts.

The first phase involved ten experts to assign weightage for health, well-being and productivity. In the second phase, 206 questionnaire survey data were collected from office building occupants throughout Malaysia. Exploratory factor analysis established new WELL concepts for office buildings. Partial least-squares structural equation modelling examined the influence of the newly developed WELL concepts on the existing WELL v2 concepts.

Two new WELL concepts were developed: “space and services”, consisting of sufficient space, workstation privacy, office layouts, building automation systems, cleanliness and information technology (IT) infrastructure, and “building security”, consisting of security systems and safety at parking lots. Here, “space and services” influences all existing WELL v2 concepts, and “building security” influences the water, nourishment, mind and community concepts of WELL v2.

This study uncovers holistic WELL building concepts to support occupants’ health, well-being and productivity with additional new features and concepts for construction industry policymakers to establish holistic building assessment tools.

Most of the emphasis in the green building literature on the green performance of buildings has been on optimizing energy and resource efficiency. Admittedly, from the perspective of the sustainable construction industry, making optimally energy and resource efficiency, often seen as a technical challenge, has a premise role in green building projects. However, green buildings need to optimally meet the health, well-being and comfort requirements of their occupants and their environmental quality targets. In that context, perceived quality is a crucial determinant of occupant satisfaction and can play a critical role in the user-oriented improvement of the green performance of buildings. While previous research has highlighted issues related to occupant satisfaction, none of them examines green buildings from a perceived quality perspective. Therefore, the study attempts to fill this research gap.

Firstly, to reveal the positive and negative satisfaction of the building occupants according to the green building features, the review of previous research in the related literature is supplemented by an exploratory study of case studies evaluating occupant satisfaction in green buildings. Then, a conceptual framework is proposed to link perceived quality and green building features towards occupant satisfaction.

A review of the case studies in 49 research articles has shown deficiencies in a comprehensive understanding and approach to the perceived quality of green buildings. In response, the development of a framework for conceptual interrelationships may provide a pathway for more detailed quality assessments for future research. In this study, the proposed conceptual framework has the potential to provide a conceptual basis for future models in determining the relationship between quality expectations and quality experiences in green buildings. It can also serve as a constructive approach for assessing occupant satisfaction in the quality-driven improvements of green buildings and further investigation of the importance of various quality cues, quality attributes and their interactions.

This study aims to incorporate green building features and perceived quality concepts into a framework that can form the basis for assessing occupant satisfaction in green buildings. The ultimate goal of the proposed conceptual framework is to generate an insight that can contribute to rethinking the perceived quality of green buildings and developing more occupant-driven solutions for future green buildings.

Logistics real estate has been experiencing a recent rebirth led by the growth of retailing and e-commerce. Although these sectors are looking for facilities matching their logistics needs, the identification of the most suitable building becomes a challenging task. To date, from both the practitioner’s and academic perspectives there is a lack of models for assessing the quality of logistics facilities together with functionality (i.e. whether a warehouse is suitable for hosting a given logistics activity). The purpose of this paper is to fill this gap by developing a rating model for assessing the quality and functionality of logistics facilities.

A three-pronged methodology was adopted. First, a Systematic Literature Network Analysis (SLNA) was carried out to identify the relevant features that must be taken into consideration when assessing logistics real estate. Second, a Delphi method involving experts in the field was used to fine-tune the list of features that emerged from the SLNA process and to evaluate the importance of each feature from a company perspective. The rating model was developed and validated through pilot tests on 27 logistics facilities.

The rating model is divided into four sections: location, technical specifications, external spaces and internal areas. As an output, the model determines the building quality and main functionality, together with a gap analysis to detect the weakest emerging elements.

This research fills an identified research gap in the logistics real estate literature. Specifically, it offers a quantitative and shared evaluation method, which can be used to estimate building quality and functionality, thus extending the scope of the previous assessment methods available.

Sustainable features are gradually becoming important considerations by commercial real estate users. This is because of their considered impact in reducing operating costs and potential at reducing the negative impacts of buildings on human health and the natural environment. This chapter sought to examine the demands for sustainable features by users of commercial real estate like offices in Lagos State, Nigeria. It also evaluated the factors influencing demand for them to achieve value for money and enhance real estate investment decisions. The quantitative research methodology was adopted, and primary data were collected via questionnaires distributed to 134 purposively selected estate surveying firms in the study area. Ninety-five representing (70.9%) were returned and found useable and were analysed with the aid of descriptive statistics of percentages, mean and relative willingness index. The study found that power/energy-saving features are in high demand as alternatives to the epileptic nature of power supply in the country. The study recommended the need for the government to encourage the adoption and incorporation of locally made sustainable features in commercial real estate and to subsidise them for use in the Lagos commercial real estate market. Thus, it is concluded that with the right environment created by policy makers, sustainable features in buildings have huge potentials to contribute to prevent environmental problems in an emerging commercial real estate market like Nigeria.
