With the expansion of economic activities, sustainable development in construction industry got more attention worldwide. Hence, industry practitioners are more concerned on achieving sustainable construction goals to make more effective and efficient services. The Smart Building concept can be implemented with advanced building technologies to achieve clients' requirements with in the economic, environmental and social parameters while enhancing building performances efficiently. To explore the applicability of Smart Building concept to enhance sustainable building practices in Sri Lanka, the qualitative research approach was used in this research. The opinions of the smart and sustainable construction experts were obtained through semi-structured interviews. Smart Building concept is novel to the Sri Lankan construction industry and the implementation is still in the initial stage. However, the perception of the construction industry on the Smart Building concept is focused on a strong and positive direction. The recognised sustainable benefits of Smart Building concept implementation can be used as a promoting tool to make interest on Smart Buildings. Most of these benefits are long term and most of the clients do not recognise the value of Smart Buildings in terms of sustainability. Therefore, improving the knowledge and awareness of the developers is vital during the implementation process within the local context. Lack of financial resources, complex technology requirement, reluctant to commence new technologies and lack of knowledge of developers and owners are the main barriers that are existing within the local context. Mitigating these barriers will expedite the implementation process of Smart Building concept and will upgrade the performance of the local construction industry dramatically.

“…These attributes include starting/stopping building systems optimally, enabling the monitoring and control of building facilities, supporting optimal equipment time scheduling, enabling alarm settings and automatic notification, and en-suring building safety. Kumara et al [18] invited a small group of building professionals (25 of them) to take part in a questionnaire survey. They reported that participants ranked real time monitoring as the most important attribute of BMS, followed by trend analysis, and alarm reporting.…”

Smart buildings conserve energy and create a responsive, comfortable, and productive indoor environment for users and occupants. As a crucial component of smart buildings, smart building management system (SBMS) should provide a wide range of functions and bring about the intended benefits upon successful deployment. This paper identifies salient SBMS attributes and explores key factors influencing building professionals’ intention to use the system in commercial buildings. Responses were collected from 327 Hong Kong building professionals. Data were analyzed by exploratory factor analysis and structural equation modeling based on the refined Unified Theory of Acceptance and Use of Technology (UTAUT). Exploratory factor analysis shows that intelligent building operations and safety and recovery readiness are two dimensions of SBMS emerged. Specifically, intelligent building operations include intelligent and optimal scheduling of building systems, monitor and control of building facilities, having an intelligent and interactive interface, and enabling alarm settings and automatic notifications, showing the importance on the application of electrical engineering in smart building management. Structural equation model (SEM) results indicate that facilitating conditions affect habit, hedonic motivation, social influence, performance expectancy and effort expectancy. Additionally, habit, hedonic motivation and effort expectancy significantly affect building professionals’ intention to use SBMS. Practical implications of SBMS attributes for energy management and the ways in which SBMS is encouraged to be used by building professionals are given.

“…Also, it has been applied in order to study the energy performance of buildings [134,135], optimization of multidimensional modeling for decision support [136], and with smart buildings [112,134]. However, there is a number of techniques implemented to analyze and measure comfort of occupants in terms of indoor quality and operational management based to reduce the energy-use [137].…”

Energy Management Systems and Strategies in Buildings Sector: A Scoping Review

Energy management systems in buildings (EMSs-in-Bs) play key roles in energy saving and management to which an efficient energy management system in buildings (EMS-in-Bs) design contributes. Different scope-based designs of EMS-in-Bs are reviewed. The objective is to highlight different scope-based designs of EMS-in-Bs in which scopes of reviewed papers aim to implement a function of, for example, "monitor energy performance", "estimate energy-use", or "control energy-use". This paper aims to constitute a comprehensive conception of how efficient such an EMS-in-Bs to perform more than one scope (i.e., function). Meaning, is the proposed EMS-in-Bs able to perform several sequential functions? This paper's contribution is to give a function-focused EMS's review utilizing the scope of reviewed papers. That is, reviewed papers are classified based on the scope/function the selected EMS-in-Bs is designed for. This could help select an EMS-in-Bs to perform certain scope/function(s). Another contribution is that, numerous EMSsin-Bs are reviewed in a classified way so that the most adequate EMS-in-Bs for a certain scenario considering the performed scopes/functions e.g., "monitor" are highlighted. Findings showed that "control-optimize"functioned EMS-in-Bs achieved highest energy-saving rates ~30% compared to "estimate-predict" with 10%. Findings, insights given by reviewed studies, current problems faced, future directions, and remarks are drawn in conclusion. Analysis done on reviewed papers has found that the highest and lowest averagedenergy saving rates were obtained with papers whose their scopes are implementing "control"-with-"optimize" and "estimate"-with-"predict", respectively. Energy saving rates for these two classes of scopes have been equal to 22.57% and 10%, respectively. We recommend that there is a need to enhance the estimation-and prediction-related EMS-in-Bs to achieve a higher energy saving rate.
