Abstract
Purpose
With the advancement of technology and more attention to environmental issues, building information modeling (BIM) and green building have become two new and growing trends in the construction industry. Therefore, this study proposes a new strategy that integrates BIM and green building rating assessments with an emphasis on Iran Green Building Rating System (IGBRS).
Design/methodology/approach
By creating a Revit-IGBRS project template that includes sheets related to all credits, the project compliance with the IGBRS credits and management of submittal documents for certification has been facilitated. Finally, a case study of the materials and resources category of the IGBRS system was performed to validate the BIM-IGBRS application model. All 8 criteria of this category were examined by using Dynamo programming for the Revit sample project.
Findings
A practical model for BIM and IGBRS integration is presented, which allows designers to be aware of the IGBRS scores obtained before the project’s construction phase and examine different scenarios for the highest scores. Overall, this study showed that integrating BIM and the Iranian rating system is possible with some constraints, and adding some features to BIM software can promote this integration.
Originality/value
Given that no study has been conducted on the integration of BIM with the Iran Green Building Rating System (IGBRS), the present research investigates utilizing building information modeling to meet the credits requirements of this rating system. The results of this research can be generalized and used in other green rating systems.

Abstract
Purpose
The survival of hotel business in maintaining market competitiveness depends on the constant improvement of the quality of hotel facilities and services. The key to sustain hotel business is lean on the adaptability of the hotel management team towards current lifestyle trends and its surrounding context in fulfilling customer satisfaction. Because of hotel operating service complexity, the hotel contributes a higher impact on environmental degradation in performing their daily activities. Therefore, hoteliers need to determine sustainable strategies to minimize environmental impact and at the same time be able to provide satisfaction to their customers. However, green initiatives require a proactive action by the organizational management engaging both employees and guests in the environmental management process. Thus, this paper aims to review the concept of green practices, the implementation of green practices from the stakeholders’ perspectives (manager, employee and customers) in the hotel industry, the performance impact from the green practices on the sustainability pillars and to further develop a conceptual green practice to sustainable hotel operations and performance impact.
Design/methodology/approach
This paper identified relevant empirical research that published in the recent 10 years from January 2012 to December 2021. The articles are searched through reputable databases such as Emerald, Elsevier and Taylor and Francis. The obtained data were screened preliminarily from 108 research papers. The post-screening process has finalized a total of 57 articles as the findings for this paper, where the themes were delineated to the attributes that need to implemented by the stakeholder in hotels industry, that is, manager’s perspectives, employee’s perspectives and customer’s perspectives.
Findings
The findings of this paper revealed that there are 27 attributes of green practices and initiatives for sustainable hotel operations from the manager perspectives (10 attributes – Green Marketing Strategy, Green Managerial Attitude, Eco-Innovation Investment, Marketing and Sustainability, Environmental Management Strategy, Green Supply Chain, Green Managerial Awareness, Green Procurement, Green Human Resources and Green Technology), employee perspectives (5 attributes – Employee Green Awareness, Employee Green Training and Educating, Employee Environmental Behaviour, Employee Green Performance and Employee Green Reward) and customer’s perspectives (12 attributes – Customer Perception, Customer Loyalty, Customer Awareness, Customer Behaviour, Customer Trust, Green Supply Chain, Green Value, Green Marketing Strategy, Customer Perceived Value, Service Quality, Brand Image and Hotel Design). All of the attributes are aligned to the performance effectiveness as the major concern in the hotel’s operations and impacted towards the sustainability pillars, environmental performance, economic performance and social performance. Sustainable practice in organization benefits the owners towards sustainable economic, environmental, socio-cultural and legal policy.
Originality/value
This review paper provides key elements of current green practices and sustainable initiatives for the hotel’s operations, as proactive measures. The novelty of the findings is to be able to convey valuable inputs to the relevant stakeholders (hotel’s owner, consultants, designers, maintenance officers, hoteliers, staffs, customers and end-users) in perceiving the elements of green practices into the preliminary planning of the hotel’s design. The review also helps to identify practices and measures to the performance impact to the hotel’s operations.

Abstract
Purpose
The processes of convergence are particularly challenging in the Sub-Saharan African frameworks, considering the diversity of contexts and endogenous particularities. Creating conditions to support these nations to improve their socioeconomic dynamics and performance requires additional contributions from international organisations, governments and the scientific community. In this scenario, this paper aims to analyse the convergence process in Sub-Saharan African countries over the past three decades.
Design/methodology/approach
To achieve these objectives, data from the World Bank were considered for the gross domestic product (GDP) per capita over the period 1990–2021. This statistical information was assessed through panel data approaches based on the models from the convergence theory. Specifically, the concepts of sigma and beta convergence were addressed, as well as the concept of catch-up rates.
Findings
The findings obtained highlight evidence of the existence of clubs of convergence among the Sub-Saharan African countries and the processes of catching up. These results may be relevant support for the policymakers and international funds and programmes.
Originality/value
This research provides a new perspective on the convergence of GDP per capita in Sub-Saharan African countries, based on an analysis focused on groups of countries identified on the basis of catch-up rates. This approach presents a way of dealing with the different specificities of these nations.

Abstract
Purpose
The rising concern for the accuracy of residential valuations in Nigeria has created the need for key stakeholders in the residential property markets in the study areas to know the level of accuracy of valuations in order to make rational residential property transactions, amongst other purposes.
Design/methodology/approach
A blend of descriptive and causal designs was adopted for the study. Data were collected via structured questionnaire administered to 179 estate surveying and valuation (ESV) firms in the study areas using census sampling technique. Analytical techniques such as median percentage error (PE), mean and relative importance index (RII) analysis were employed in the analysis of data collected for the study.
Findings
The study found that valuation accuracy is greater in the residential property market in Abuja than in Minna, with inappropriate valuation methodology as the most significant cause of valuation inaccuracy.
Practical implications
The practical implication of this study is that a reliable databank should be established for the property market to provide credible transaction data for valuers to conduct accurate valuations in these cities. Strict enforcement of national and international valuation standards by the regulatory authorities as well as retraining of valuers on appropriate application of valuation approaches and methods are the recommended corrective measures.
Originality/value
No study has comparatively examined the accuracy of valuations in two extremely different residential property markets in the country using actual valuation and transaction prices.

Abstract
Purpose
Building defects are becoming recurrent phenomena in most high-rise buildings. However, little research exists on the analysis of defects in high-rise buildings based on data from real-life projects. This study aims to develop dashboards and models for revealing the most common locations of defects, understanding associations among defects and predicting the rectification periods.
Design/methodology/approach
In total, 15,484 defect reports comprising qualitative and quantitative data were obtained from a company that provides consulting services for the construction industry in Victoria, Australia. Data mining methods were applied using a wide range of Python libraries including NumPy, Pandas, Natural Language Toolkit, SpaCy and Regular Expression, alongside association rule mining (ARM) and simulations.
Findings
Findings reveal that defects in multi-storey buildings often occur on lower levels, rather than on higher levels. Joinery defects were found to be the most recurrent problem on ground floors. The ARM outcomes show that the occurrence of one type of defect can be taken as an indication for the existence of other types of defects. For instance, in laundry, the chance of occurrence of plumbing and joinery defects, where paint defects are observed, is 88%. The stochastic model built for door defects showed that there is a 60% chance that defects on doors can be rectified within 60 days.
Originality/value
The dashboards provide original insight and novel ideas regarding the frequency of defects in various positions in multi-storey buildings. The stochastic models can provide a reliable point of reference for property managers, occupants and sub-contractors for taking measures to avoid reoccurring defects; so too, findings provide estimations of possible rectification periods for various types of defects.
