Purpose The purpose of this paper is to explore sourcing strategies for facilities management services using core-competency theory of outsourcing. The aim is to develop a screening framework for deciding the suitability of outsourcing versus in-house delivery for these services based on three levels of managerial functions prevalent in a typical commercial organization. Design/methodology/approach A questionnaire survey was administered for facilities managers in Sri Lanka to investigate the relative importance of these managerial functions for facilities management services and obtain their opinions on the best delivery mode. The managerial functions were derived from a literature review and verified using three semi-structured interviews prior to the questionnaire survey design. Findings The findings showed that facilities management services that are aligned to strategic functions are suitable for in-house delivery, while those that are aligned to tactical and operational functions for outsourcing. Research limitations/implications Further studies should be conducted and extended to other types of organizations beyond commercial ones. Secondly, the quantitative study employed a smaller sample (n = 40), and the survey items were based on the review of literature which was verified using a very small number of interviews (n = 3). Practical implications The proposed framework can be utilized when choosing the best facilities management approach for commercial organizations in developing countries such as Sri Lanka. Originality/value This study contributes to the body of knowledge on the subject of facilities management by exploring the context in Sri Lankan which has not previously been done.

Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

Purpose The suppliers are recognized as important external sources who can significantly contribute by working together with the buyer during the innovation process. Operational capabilities of suppliers can be one of the considerable factors when selecting them to participate in the activities at the front-end of innovation. However, proper understanding of the influence of operational capabilities of suppliers on front-end decision-making in apparel product innovation is still very limited particularly in the context of the Sri Lankan apparel industry. Therefore, this study aims to explore the influence of operational capabilities of suppliers on the front-end decision making in apparel product innovation in Sri Lanka. Design/methodology/approach Both semi-structured interviews and a questionnaire survey were used as data collection techniques. Six senior managers for the interviews and 60 participants for the questionnaire were randomly selected. All those who participated in interviews and the questionnaire respondents have been involved in the front-end of innovation in different apparel manufacturing organizations in Sri Lanka. Findings The results indicated that the operational capabilities of suppliers had a direct positive influence on front-end decision-making, and the suppliers’ production flexibility was found to be the most influential. Further, the results highlighted that 27.3% of the front-end decisions associated with apparel product innovation in Sri Lanka were influenced by the factors governing operational capabilities of suppliers. Originality/value The findings of the research will be beneficial for both academia and industry. The findings will be useful to extend the current understanding and make a noteworthy contribution to this topic and to provide useful and practical guidance to material suppliers and supporting industries who work with Sri Lankan apparel manufacturing.

Purpose Green roofs are acknowledged as a method to substitute greenery washed out by the urbanization. They provide many ecological and sustainable benefits of greenery; reduce the adverse effects of high-rise building constructions. Though this concept is more popular across many countries over the past few decades, still, implementation of this technology in Sri Lanka is new and scant. Hence, the purpose of this paper is to identify and analyze the potential of green roofs in high-rise buildings in Sri Lanka. Design/methodology/approach The data collection was conducted through expert interviews and questionnaire survey. Expert interviews were carried out to validate the prospects and restraints identified through literature review to the Sri Lankan context and analyzed using content analysis. Questionnaire survey identified the most significant prospects and restraints using descriptive statistics and paired sample t-test. Purposive sampling was used to select participants. Findings Reduction of air pollution, aesthetical appearance, thermal benefits and energy savings, reduction of an urban heat island effect, the addition of points in the green rating system are the top most significant prospects that need to be highlighted in promoting green roof systems in Sri Lankan high rises. Less space allocation on rooftops, lack of technical competence and lack of awareness and research are restraints that need most effective elimination strategies to encourage green roof systems. Originality/value The first identified and quantified prospects and restraints for green roof system in Sri Lankan high-rise buildings can be utilized by the government, donors, multi-lateral agencies to promote the sustainable development in Sri Lanka and this knowledge could be used in different scale awareness programs. The value of this paper is such that the paper discusses the links of green roofs with the other facets of sustainability. The new legal reforms and amendments in Sri Lanka could potentially be pending with findings of this study.

LEED is an universally used green ranking system in the world. Among the six evaluation factors it specifically focuses on water use reduction, water efficient landscaping and innovative wastewater technologies. LEED provides a structure or collection of metrics to determine the water efficiency level that a building can achieve. Most of the hotels worldwide are inclined towards gaining LEED certification which is prompted by the higher volumes of water consumption in the facility. LEED is a US created rating system and the most categories of LEED certification are built according to the US aspects. Being an Asian country, Sri Lankan hoteliers also attempt to obtain LEED certification to their hotels with the motive of becoming in order to be more efficient. However, some of LEED requirements under the water efficiency category does not match the Sri Lankan hotel industry requirements. Therefore, the aim of the study to identify whether the LEED requirements under the water efficiency can be applied to Sri Lankan hotel industry. To accomplish the aim, literature synthesis was conducted to explore the water efficiency practices used by LEED certified hotels in other countries. A qualitative research methodology was subsequently adopted, directing semi-structured interviews with two LEED certified hotels in Sri Lanka to identify the LEED practices used in Sri Lankan hotel industry. Thematic analysis was conducted to analyse the collected data. Finally, a framework was developed to compare and contrast the water efficiency practices used in LEED certified hotels in other countries and Sri Lanka.

The study examined the status and impact of audit education on the audit expectation gap, as existence of such a gap is noted to be harmful to the accounting and auditing profession. Accordingly, undergraduates of a regional national university in Sri Lanka (in three categories as: undergraduates who had not followed an auditing course, who had followed a basic auditing course, and who had followed an advanced auditing course) and professional auditors were selected and a questionnaire survey that included statements on the duties of the auditors was administered. The results of the independent sample t-test indicate the existence of an audit expectation gap in the Sri Lankan context; and that audit education had an effect in reducing such a gap. However, further analysis indicated that only an advanced auditing course had resulted in minimizing such expectation gap (particularly in reducing the unreasonable expectation gap) compared to who had followed a basic auditing course. These findings are expected to have significant educational policy implications.

Corporate Social Responsibility (CSR) is a concept, which is broadly determined as ensuring the efficacy of the organisation in integrating social and environmental considerations into organisational operations. In Sri Lankan context, a great enthusiasm can be seen among organisations to engage in CSR initiatives. Having considered the importance and impact, the study aims to investigate the importance of CSR initiatives by construction organisations in disasters in Sri Lanka. Thus, a mixed method research approach was followed as the methodology of this study. Findings are based on semi-structured interviews held with construction industry professionals. Findings of this study revealed that the implementation of CSR initiatives is more important during a disaster situation in the aspects of both affected party and aiding party. Moreover, construction organisations implement CSR during disaster situations by considering it as a mandatory responsibility of an organisation. Further, most of the construction organisations engage in CSR implementation during natural disaster situations. In practice all the construction organisations tend to engage in reactive initiatives. More importantly, it is revealed that both the organisational work force and society are benefitted through CSR implementation in disaster situations.
