Abstract
Integrated design is a strategy to develop sustainable architecture projects incorporating multidisciplinary work and environmental performance assessments, which has provided significant advancement to public buildings in developed countries. This paper presents a review of some aspects of integrated design for the planning and construction of energy efficient housing in the south of Chile, as part of the reconstruction process following the earthquake on 27th February 2010. Firstly, a synthesis is made of the characteristics, implicit conditions, participants, steps, resources and expected results of an integrated design approach according to existing references. This is then contrasted with normal housing design practice in Chile according to current building regulations and interviews with professionals in the field. The design processes of experimental houses and housing projects that place specific focus on energy performance are then analysed, with follow-ups and interviews to review significant aspects. After examining those experiences, the authors identify some particular features and resources of integrated design that promote environmental improvements.

Abstract
Purpose
This study aims to introduce the results of a research carried out to develop a prototype of a highly energy-efficient modular detached house, called CASA+ CASA means HOUSE in spanish, adapted to the climatic features of central-southern Chile. The project enables a sustainable alternative to facilitate the reconstruction of the residential areas after the impact of the 2010 earthquake.
Design/methodology/approach
The methodology is based on an “integrated design process” of a case study that proposes a constructive response that quantitatively and qualitatively improves the initial data of traditional dwellings. The characteristics of the new system have been simulated with specific software to validate the final decisions, considering the cost–benefit ratio.
Findings
Simulation tools were used to assess and improve the system’s energy performance with respect to present options and to analyse its economic and construction viability. We obtained several economically competitive housing prototypes that substantially reduced energy consumption and the CO2 footprint by between 20% and 80%.
Research limitations/implications
The prototype has not been developed, as we are waiting for funding, but all its energy features have been simulated.
Practical implications
Furthermore, this experience also identified similar modifications made to the design of the houses, which revealed general possibilities for improving energy performance.
Social implications
The origin of this research is a public call for international researchers to improve the quality of the new homes to be built in Chile after the strong earthquake of 2010. The result of the research has been put at the direct service of Chilean society and in other international projects for the construction of low-energy social housing.
Originality/value
These are the result of a long research aimed at establishing a new architectural model that, in addition to improving the architectural quality of the product, obtains significant improvements in energy consumption and CO2 emissions. The most particular aspect is the practical vocation and its implementation with real construction with the support of construction companies.

Abstract
Purpose
This paper aims to review the application of integrated design strategies in several cases of housing in south-central Chile in search of ways to significantly reduce energy loss and demand.
Design/methodology/approach
First, seven main design features of energy-efficient buildings in developed countries were identified. Second, these features were reviewed in two professional case studies from architectural practices and two academic exercises on residential design in south-central Chile. In all cases reviewed, characteristics of integrated design were verified to reductions in energy loss and demand. Finally, the procedure implemented was evaluated through surveys of those practitioners responsible for each experience studied.
Findings
This process made it possible to highlight four main features of integrated design, namely, pre-established performance goals, interdisciplinary collaboration, regular broad-ranging meetings and the use of performance assessment tools. With these techniques, reductions of more than 50 per cent in the energy requirements of the housing designs were achieved, while safeguarding the functional, aesthetic and economic aspects of the projects.
Research limitations/implications
However, professionals currently working in this field did express their concern regarding responsibility for the design and the time needed to complete the process.
Practical implications
Furthermore, this experience also identified similar modifications made to the design of the houses, which revealed general possibilities for improving energy performance.
Social implications
The conclusions obtained have been exposed in conferences and graduate programmes and applied in two real projects for the benefit of society: first, the improvement of building envelopes in social housing in Temuco; and second, CASA+, a modular, prefabricated and energy efficient house prototype.
Originality/value
This paper carried out a novel review of an integrated design process in housing cases of developing countries, and identified the key features, which improve the environmental performance of dwellings.

Abstract
Purpose
This paper aims to explore the nonfinancial drivers of value creation that influence an investment decision and present a set of drivers that contribute with a useful integrated reporting to its providers of financial capital using evidence from Brazil.
Design/methodology/approach
This paper is based on a systematic literature review in the Scopus, Web of Science and Google Scholar databases in the period from 2005 to 2020. Interpretive content analysis is used in 42 documents identified to explore nonfinancial drivers to demand by providers of financial capital, which are classified according to the capitals nonfinancial suggested by the integrated report (IR). Then, the results are evaluated by Brazilian professional investors in a focus group.
Findings
The members of the focus group do not consider the IR relevant to investment decision and neither the information about natural capital nor social capital. They highlighted two nonfinancial drivers of value not identified in the previous literature.
Research limitations/implications
The focus group is limited by subjects’ availability and by the participants’ number. But its results represent initial discussions on the subject in the Brazilian context.
Practical implications
The results of this study have value, principally, to investors, target audience of IR, because it aligns your demands with the IRs content, improving its usefulness.
Originality/value
To the best of the authors’ knowledge, this manuscript is the first study to investigate the perception of Brazilian professional investors about the importance of the IR in investment decision-making and to identify content relevant to the financial capital provider’s investment decision, which can improve the usefulness of IR.

Abstract
Purpose
Organizations and markets are constantly developing and changing, impacting how organizations create value and manage supply chains. This paper aims to identify the motor themes and subthemes of academic research that relate supply chain management (SCM) maturity and business models (BMs).
Design/methodology/approach
The Science Mapping Analysis Tool (SciMAT) was used to conduct a seven-step bibliometric analysis of 889 documents indexed in the Scopus database clustering by relatedness of works and keywords. The methodological approach included content analysis of the literature, longitudinal analysis and strategic diagram analysis.
Findings
The thematic evolution analysis revealed that three themes drive the studies on SCM maturity and BM: industry 4.0 (motor theme), environmental management (transversal theme) and product management (highly developed and isolated theme). The strategic diagrams and co-word networks allowed to graphically identify the main topics connecting SCM maturity and BM. Considering this connection, the scientific mapping emphasizes the significance and strength of the link between digital technologies, technology management and manufacturing management in Industry 4.0. In addition, the connections between the subthemes revealed that circular economy and green human resource management are important concepts to advance theory and practice on the connection between SCM maturity and BM.
Originality/value
This research extends the knowledge base by providing an analysis of the key themes and the links with subthemes in the literature that relate to SCM maturity and BM. Key studies are analyzed and linked with the key topics identified using the SciMAT software. Future research avenues are outlined, providing new insights to advance theory and practice.

Abstract
Purpose
Corruption within the Nigerian Government – at all levels – is endemic and a major problem. While there is ample evidence to buttress this fact, its effects are having a negative impact on the ability of the government to meet its agreed UN sustainable development targets, as well as the credibility of the government (nationally and internationally), and its ability to deliver on quality governance. Hence, this study aims to identify the power of digital transformation in curbing corruption and improving governance for sustainable development.
Design/methodology/approach
A mixed method that encompasses the use of a systematic literature review and a bibliometric analysis was used to examine extant literatures – to derive lessons for the Nigerian Government and governments in other developing countries (most especially those in Sub-Saharan Africa).
Findings
The results obtained within this study show that digital transformation – brought by the fourth industrial revolution – is a verified solution to improving transparency and accountability in governance. However, the current technological infrastructure in Nigeria is too weak to support this innovation. Key infrastructures like high-speed internet, a harmonized data storage system, and communications among government organizations rarely exist.
Originality/value
To the best of the authors’ knowledge, the approach used in this research is unique as it is one of the earliest studies to provide a viable solution to the issue of corruption in public governance in Nigeria, while examining the effects of the digital transformation of governance globally.
