Purpose The purpose of this paper is to determine the relationship between indoor environmental quality (IEQ) and occupants’ productivity improvements in green buildings in order to propose probable enhancements of national green certification criteria. Design/methodology/approach Survey approach was selected under quantitative phenomenon. Hence, questionnaire survey was selected as a primary data collection technique. It was linked to semi-structured interviews to validate survey results. The survey data were analysed by using nonparametric statistical analysis techniques, such as significance testing and Spearman’s correlation. Statistical Package for the Social Science (SPSS) v.20 statistical analysis software was used in data analysis. Findings Seven factors were identified as significant factors which showed statistically significant monotonic correlation to major IEQ dimensions. Among those, air quality and acoustical partitioning factors confirmed a statistically significant weak positive monotonic correlation, whilst system control showed strongly positive monotonic correlation to occupants’ productivity in green buildings. Practical implications The findings can be practically implied as a basis to review the existing evaluation criteria of IEQ in national green certification system to propose probable enhancements. Originality/value The significant IEQ factors influencing occupants’ productivity were determined as the focal point of this research. Accordingly, new provisions were proposed to enhance the national green certification criteria.

PurposeThe excellence in design and greater efficiencies (EDGE) certification system has seen a gradual adoption worldwide, with Ghana having six out of its eight certified green buildings bearing an EDGE certification. However, little is known about occupants’ satisfaction with the indoor environmental quality (IEQ) of EDGE-certified buildings. Therefore, the purpose of this study is to examine the satisfaction of occupants with the IEQ of an EDGE-certified building in Ghana by identifying their perceived performance of the indoor environment relative to their perceived importance.Design/methodology/approachA survey was conducted to evaluate the performance of 12 IEQ parameters with the occupants of an EDGE-certified office building. The survey results were evaluated using a gap analysis and both traditional and alternative Importance-Performance Analysis (IPA) matrices.FindingsThe findings revealed that noise level, temperature, cleanliness, sound privacy, air quality and humidity were IEQs that required the highest priority for improvement. Daylight and artificial lighting showed no appreciable performance gap. Space layout was adequately satisfied, whereas space size was overly satisfied. Visual privacy and outdoor view were found to require low priority of improvement.Originality/valueThis study contributes to the state-of-the-art of the IEQ of green buildings. It pioneers the research that seeks to examine the IEQ of EDGE-certified buildings. The gap analysis and the IPA were effective in prioritizing the IEQs for improvement action and provided a practical research framework that helped researchers examine the performance of green buildings, thereby giving valuable feedback to policymakers and building owners.

Case Study Analysis

Purpose Higher education institutions (HEIs) should play a fundamental role in achieving the international 2030 sustainable development (SD) agenda. Quality education is the fourth of the sustainable development goals (SDGs), and one of the targets related to this is to ensure that by 2030 all learners acquire the knowledge and skills needed to promote SD. Therefore, the SDGs provide a motive for HEIs to integrate SD concepts into their day-to-day practices. This study aims to introduce a framework for HEIs’ sustainable development assessment. Such a framework guides HEIs and educational leaders to support their countries’ commitments to achieving the SDGs. Design/methodology/approach This paper presents the results of a case study analysis of the role and successful techniques of HEIs in achieving SD in three countries, namely, Germany, Japan and Egypt. Primary data was collected by semi-structured interviews with three Cairo University officials, while secondary data was collected by reviewing the universities' official websites, reports, publications and related papers. This study introduces a novel framework for HEIs' SD analysis and assessment, which guides HEIs and educational leaders to support SD to fulfill their countries' commitments to achieving the SDGs. This framework is based on the following five categories: strategic direction and institutional working practices, supporting students, supporting university staff competencies, supporting society's stakeholders and networking and sustainable campus. Consideration is given to the potential role of HEIs to support SD in each of these areas. Findings Cairo University could learn from the novel and pioneer practices of the Leuphana University of Lüneburg, and the University of Tokyo to fill in the gaps it has in different roles. It can also put more effort into adopting the suggested higher education programs of Egypt's Vision 2030. Research limitations/implications This paper is limited to a case analysis comparing three countries, Germany, Japan and Egypt. Second, this study has not considered school education, which is equally essential in countries' SD. Practical implications HEIs can use the framework and the findings in this paper to evaluate their current roles in supporting SD, identify the gaps and take actions accordingly to address their weaknesses. Originality/value The paper compares three universities, one in each of the case study countries. It draws conclusions that identify ways in which the paper's framework and findings can guide SD practice in HEIs internationally, especially those in the developing world.

Working Efficiency

Comprehensively monitoring indoor environmental quality (IEQ) parameters and their dynamic relations is essential to ensure improved productivity and a healthy environment for building occupants. Although IEQ significantly influences working efficiency, studies addressing this aspect with researchers in institutes as the focal point are limited. Thus, this study employed drill-down analyses, such as floor-by-floor and building-by-building examinations and used an occupant IEQ survey approach to evaluate working conditions in research buildings. This study systematically and objectively assessed IEQ using the Korea building occupant survey system. The results indicate that acoustic qualities affect the work productivity and satisfaction of the building occupants. The floor-by-floor analysis is necessary to identify IEQ factors and the reasons for the satisfaction of occupants. Additionally, it is important to improve the user-friendliness of the system, implement frequent survey distribution systems, and empirically analyze data associations among building, spatial, and demographical characteristics.

Energy Innovation

Purpose – The purpose of this paper is to examine the quality of collaboration towards Sustainable Energy Innovation (SEI) in Private Finance Initiative (PFI) projects. While the capacity of PFI to encourage collaboration towards innovation is largely advocated by its proponents; however, it remains to be supported by empirical evidence. Design/methodology/approach – Adopting the Complex Product System (CoPS) innovation management model, the authors assess the quality of collaboration at the interface between the innovation superstructure of public sector clients and users, and the innovation infrastructure of private sector designers, contractors and operators. Two interactional elements are examined upon which the quality of collaboration is assessed: openness of communication and alignment of objectives. The authors apply the model to four new-built PFI school projects within the context of the UK government Building Schools for the Future Programme. Semi-structured interviews with total of 50 key stakeholders were used as the primary data collection method. Findings – PFI has introduced a number of problematic issues weakening collaborative efforts towards innovation in the project environment. Particularly, the study underlines the restricting internal contractual relationships within the integrated Project Company and the misalignment of Design-Construction-Operation sustainability objectives. It also highlights ineffective communication with public sector clients and users brought in by the restricted nature of PFI engagement processes as well as the misalignment of public sector-private sector sustainability objectives. Research limitations/implications – The qualitative nature of the chosen research methodology limits the ability to generalise. The research findings need to be confirmed or rejected by means of quantitative research as representative of all PFI projects. Practical implications – The study emphasizes the public authority’s role in relation to providing the necessary conditions for the creation of a collaborative environment conducive to SEI in PFI projects. Originality/value – The study was able to expand the understanding of innovation and collaboration management processes in PFI projects in three respects: First, addressing the limited attention to innovation in PFI research, the study is the first to examine the quality of collaboration in PFI projects towards the implementation SEI. Second, examining the quality of collaboration in PFI projects through the lens of CoPS provides a new understanding of sustainability innovation and strongly indicates that the CoPS model should be expanded to account for the dynamics of innovation processes in the procurement of sustainable CoPS. Third, the explorative nature of the study was useful in generating research hypotheses that can form the basis for future research on SEI in PFI projects.

Modular Buildings

PurposeGlobal megatrends such as urbanization and ageing of the population result in fast-paced demographic changes, which pose different types of challenges for different regions. While many rural municipalities bear the burden of under-used buildings, cities are in a hurry to develop new ones to meet new space demands. The purpose of this paper is to assess the potential of relocatable modular buildings to address these challenges, following the principles of circular economy, while at the same time offering usability.Design/methodology/approachThis multiple case study explores existing relocatable modular health-care buildings in Finland. The case buildings host hospital support functions, imaging services, a health-care centre and a care home. The primary data comprise 21 semi-structured interviews and observation during factory and site visits.FindingsBased on the findings, relocatable modular buildings have many benefits and provide a viable option for cities and municipalities struggling to meet their fluctuating space demands. Some challenges were also identified, mainly derived from the dimensional restrictions of the modules.Originality/valueThis research contributes to the emerging body of knowledge on circular economy in the built environment. More specifically, the research provides a very concrete example of circularity and details a framework for usable and relocatable modular buildings. In conclusion, relocatable modular buildings could solve the challenges posed by quickly changing demographics in different types of regions and deliver both usability and circularity.

Purpose The purpose of this paper is to examine the factors affecting decision-making at the BoP and propose a framework of the consumer decision-making process at the base of the pyramid (BoP). Design/methodology/approach The qualitative research design was adopted to collect primary data. Data collected through the in-depth semi-structured interviews of the 48 BoP consumers in Kolkata and Kharagpur (India) were subjected to grounded theory analysis for theory development. Findings This study reveals that consumer vulnerability affects the decision-making process and the transaction cost at BoP level. It was observed that the consumers at the BoP make constrained choices due to their vulnerability and try to minimise transaction cost while selecting the retails. The constrained retail choice leads to a limited selection of products and brands. Originality/value This study, for the first time, has investigated the decision-making process for BoP consumers in detail. As a pioneering attempt, it sheds light on some new factors including consumer vulnerability and transaction cost that have an impact on the consumer decision-making process.

Purpose This paper aims to identify the indoor environmental quality in an affordable housing, as well as the health condition of users. Furthermore, it aims to find the relationship between quality of the indoor environment (IEQ) and sick building syndrome (SBS) and the satisfaction level of the occupants towards the IEQ factor, as well as the importance of the factors in the occupants’ view. Additionally, the purpose of this pilot study is to validate the questionnaire and identify the possible outcome of this research for the main study. Design/methodology/approach There are a few methods to achieve the objective of this paper: first is by literature review and second is by a survey. There are two types of survey made: observation survey and questionnaire survey. The purpose of observation survey is to survey the surrounding and the condition of the apartments, while questionnaire survey was distributed to the respondents in the affordable housing area. Next, is analysis and discussion of the survey, and finally, summary. Findings Aside from achieving the validity of the questionnaire survey, the results of the survey have found that the respondents are dissatisfied with the noise and glare level, as well as the amount of artificial lighting in their unit. Additionally, they have rated health, ventilation and amount of air movement as the most important IEQ factors. More importantly, the occupants have experienced the symptoms of SBS and the health condition of the building occupants. The results show that the most frequent symptoms affected the respondents are fatigue, dizziness and a headache. Originality/value This paper has indicated the IEQ in the affordable housing and identifies the health risk of occupants, specifically in Malaysia.

PurposeThis article is theoretical and empirical in nature. Its purpose is to determine whether a lifestyle resulting from a particular personality type is significant for elements of a food marketing offer, which final purchasers would like to co-create with offerors.Design/methodology/approachA cognitive-critical analysis of the world literature on the subject was used to prepare the theoretical section. The results of the analysis indicate a cognitive and research gap in analyzing the above aspects. In order to reduce the gap, empirical studies were conducted in which a questionnaire was used to gather primary data. The data were subjected to quantitative analysis using statistical analysis including exploratory factor analysis, Pearson chi-square independence test, V-Cramer coefficient analysis, Kruskal–Wallis test and cluster analysis.FindingsThe results of the statistical analysis allowed three research hypotheses to be verified. It was found that there is dependence between respondents' lifestyles and elements of a marketing offer which they would like to co-create with offerors. It was also found that a lifestyle is a feature differentiating both material and non-material elements of a marketing offer which respondents would like to co-create with offerors. Such dependence was identified for, respectively, a material product, service and brand, regardless of whether these considered a company or a product. Thus, research hypotheses were proved to be valid for respondents.Research limitations/implicationsThe results obtained from the research have a cognitive and applicability value. They contribute to the theory, including marketing and customer behavior. They can also facilitate the shaping of good mutual relationships between offerors and final purchasers as important partners cooperating in the process of creating marketing values.Originality/valueThe originality of the approach presented is confirmed by the fact that until now elements of a marketing offer which purchasers would like to co-create with offerors have not been analyzed in the context of a lifestyle either in theory or in practice.
