Integrating internet of things (iot) and facilities manager in smart buildings: a conceptual framework
(Ceylon Institute of Builders, 2018-06) Suriyarachchi, CS; Waidyasekara, KGAS; Madhusanka, N; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
A Facilities Manager (FM) plays a key role in managing all non-core services of a building by integrating people, processes, places, technology, and etc. Considering the effective integration of aforementioned sectors, a facilities manager needs to deal with the evolving information and communication technology. Presently, the most emerging trend is the “Internet of Things” (IoT) which is developing rapidly throughout the world. Subsequently, IoT concept is apparent in the field of facilities management mainly in the sector of building automation with intelligent controls. This intelligent automation results in creating SMART buildings which has become a global trend in the building sector. In such a situation, Sri Lankan building traditions should also be updated with the emerging IoT based technological trends to gain competitive advantages. Even though this is a timely requirement, user acceptance of new technologies and other external factors directly affects new IoT trends in Sri Lankan building culture. Due to the lack of data available in practice, this research was adopted using qualitative approach to identify the existing limitations and challenges of the integration of IoT and FM in smart buildings. This paper presents a conceptual framework which was developed by critically reviewing the secondary data. The proposed framework represents the relationship between FM and IoT in SMART buildings.

Mapping and improving sustainable construction management through social network analysis: a review
Madhusanka, N; Pan, W; Kumaraswamy, M
Social Network Analysis (SNA) has been used in multidisciplinary research during the past two decades due to the unique nature of network visualisation and extensive analytical capabilities. This tool has also gained increasing attention among the researchers in the sustainable construction arena in recent years. Nevertheless, a thorough review has not yet been done to review the application of SNA in the sector of sustainable construction. This paper attempts to address this gap through a comprehensive review of previous journal publications. Accordingly, 73 journal papers were initially identified for review through the “Web of Science “publications database. Subsequently, a bibliometric analysis was done through “VOS viewer” software package to identify the research trends throughout the past years. The results show significant progress in relevant publications during 2014-2018 and a major contribution to research from China. After an extensive filtration process, 17 particularly relevant journal papers were identified which have applied both social network visualisation and analysis techniques for the sustainability aspects of construction. The contents of these papers were comprehensively analysed in terms of data collection methods, network analysis techniques, network structures and sustainability knowledge areas. Finally, this paper contributes to theoretical knowledge in this domain, by suggesting a future research direction through a SNA conceptual model to analyse stakeholder collaborations for project life cycle sustainability initiatives. The findings of this paper will serve as a good source for future researchers to comprehensively identify, compare and contrast the applications of SNA techniques for sustainability related studies in the construction sector.

Mitigation of challenges in sustaining green certification in the Sri Lankan hotel sector
(Emerald Publishing Limited, 2018) Bandara, C; Dissanayake, DMPP; Karunasena, G; Madhusanka, N
The successful continuation of green certification in the Sri Lankan hotel sector is vital for tourism industry as well as the economy of the country as it balances the economic interests with social and environmental responsibilities. However, it has become an issue in the Sri Lankan hospitality and tourism industry to sustain green certification due to many challenges. The prevailing situation highlights the need of exploring long-term strategies to mitigate challenges in sustaining green certification which has not been researched to date. Thus, the purpose of this paper is to propose strategies to mitigate challenges in sustaining green certification in the hotel sector in Sri Lanka.
