PurposeLife cycle assessment (LCA) has considerably contributed to increasing the environmental friendliness of buildings in developed countries. However, it is hard to find evidence on the application of LCA for buildings in developing countries; particularly, Sri Lanka. There is a lack of research to compare the status of LCA of buildings in developed countries vs developing countries. In this context, the purpose of this study aims to examine the status of LCA implementation for buildings between developed countries and Sri Lanka, a developing country.Design/methodology/approachThe exploratory research was adapted, and in-depth interviews were held with LCA professionals from Sri Lanka and developed countries, respectively.FindingsRelatively less attention has been paid to the implementation of LCA for buildings in Sri Lanka compared to the developed countries due to the time and effort required to collect life cycle inventory data and limited stakeholder understanding of the LCA. Hence, this study proposed improvements, including the development of LCA databases containing region-specific data and conducting programmes to raise stakeholders' awareness to address the gaps in Sri Lanka.Research limitations/implicationsThe identified LCA implementation process for buildings could be used as a guide for first-time LCA users, and it equally makes a valued reference for experienced practitioners.Originality/valueA limited number of the studies formulate a comparison between the LCA for building in developed countries and developing countries. This research attempts to address this knowledge gap.
The construction industry plays a significant role in the economic growth of a country. Nevertheless, the construction industry has created severe adverse environmental impacts. Therefore, green building technologies are implemented to alleviate the adverse effects of the construction industry. Using green materials instead of conventional building materials with high environmental impacts has been identified as one such implementation. However, there seems to be much confusion in defining green building materials. Hence, it is vital to explore the features of green building materials. Therefore, this article investigates green features that qualify the building materials as green building materials. A qualitative research approach was selected as the research methodology, and semi-structured interviews were conducted with seven green building experts. The data was analysed using content analysis. Findings revealed that recycled content, local availability of materials, embodied energy of materials, use of rapidly renewable material, usage of waste material for the production process, material wastage content in the production process and pollution prevention in the production process are the green features. The study results guide the identification of green building materials that can replace the materials with poor environmental sustainability.
The hotel sector is directly combined with customer loyalty as it has become increasingly obvious by incorporating its’ antecedents with customer satisfaction and trust. Customer loyalty is influenced by customer satisfaction of hospitality service when it is significantly related to service quality. Sustainability is an important concept that can adapt to achieving customer loyalty in the Sri Lankan hotel sector. Indeed, most conventional hoteliers in Sri Lanka do not have the idea of success in achieving customer loyalty through the sustainability concept. Also, despite the abundance of research on the concept of sustainability, a gap in literature could be identified, when it comes to analysing the customer loyalty aspects toward sustainable hotels in Sri Lanka. This study is therefore aimed to bridge the gap that exists in the literature to prove the success of adopting the concept of sustainability in achieving customer loyalty. A qualitative research approach with two case studies was used to achieve the aim of the study. The selected cases include two green-certified five-star hotels which are under the topmost sustainable hotels in Sri Lanka according to Sri Lanka Tourism Development Authority. A total of 10 interviews were conducted from both cases. The collected data were analysed using content analysis. The customer loyalty aspects were identified on the deriving basis of self-influence factors of customers and their consideration of benefits in sustainable hotels. The study unveils an analysis of the interconnection between sustainable hotels and customer loyalty. The findings provide the path to conventional hotels to identify the success of implementing sustainability concept in achieving customer loyalty.
