Application of nD BIM Integrated Knowledge-based Building Management System (BIM-IKBMS) for Inspecting the Post-construction Energy Efficiency
The evolution of construction industry towards sustainability highlighted the absolute necessity to inspect sustainable performances throughout the post-construction building lifecycle. Correspondingly, application of relevant building management systems (BMS) to achieve this goal is mandatory (Ippolito, Riva Sanseverino, & Zizzo, 2014). In addition, conventional post-construction building inspection methods are outdated and less effective. Therefore; this research aims to propose specific utilization of BIM during building maintenance for the consequential post-construction energy efficiency. Contemporarily, Building Information Modelling (BIM) is considered as a leading technology capable of being utilized in Architecture, Engineering, Construction (AEC) practices highlighting its critical role in enhancing the effectiveness of project delivery from conceptual initiation to eventualization and even post-construction maintenance (Ding, Zhou, & Akinci, 2014; Volk, Stengel, & Schultmann, 2014). Alternatively, despite the recent presentation of BIM to the AEC industry, it has widely emerged to an undisputedly contributive technology towards advancement of AEC implementations. Furthermore, BIM’s capability of nD project integrations has prominently highlighted its potential effectiveness while being accurately incorporated with sustainable performances (Farr, Piroozfar, & Robinson, 2014). Moreover, researchers have highlighted that information gathering and modelling through BIM can reduce respective building energy consumptions (Lawrence et al., 2012). The remarkable proportion of global energy consumption by the construction industry has fundamentally driven the concentration on decreasing the building energy consumption via amplified sensor data and improved computational support for building controls (Klein et al., 2012). Subsequently, it is vital to balance the maximization of building energy efficiency and users’ desired level of comfort while employing an efficient BMS for sustainable maintenance of facility operations overstressing the implication of post-construction building inspection. Researchers have overstressed that application of an efficient Facility Maintenance and Management systems (FMM) enables executives to detect problems primarily and sustain the facility more effectively (Chen, Hou, & Wang, 2013). On the other hand, the conventional inspection method of progress tracking practice would solely rely on manual visual assessments and periodical respective reports. This progress consisted of logs and checklists manually prepared to indicate the project’s level of adaptability with the required milestones and specifications (Bosché, Ahmed, Turkan, Haas, & Haas, 2014). Effectiveness and accuracy of the corresponding inspection progress would have been affected based on the individual’s personal judgment and observational skills. Additionally, high probability of inaccurate manual building inspections plus the lack of real-time input of dynamic factors urges development of automated BMS. Therefore, Building Information Modelling (BIM) plays a key role towards automation in construction and corresponding management systems. However, adequate skills; competence and enthusiasm of construction role-players and contractors is a significantly important issue towards future success of such propositions (Miettinen & Paavola, 2014). Additionally, the progression of AEC building delivery includes design, construction, contracting and maintenance. This complex process, engaging multi-layer and multi-domain information storage and exchange, necessitates integrative contributions from versatile and incorporative professional teams thus; competent information sharing among players is a critical factor towards success therefore; a proposed BIM system capable of resolving AEC interoperability complications would remarkably enhance the overall project output and respectively the building energy efficiency throughout its lifecycle (Dong, O'Neill, & Li, 2014). Despite the nD capability of BIM enabling its potential practice during versatile building lifecycle phases, designers-contractors focused primarily on the application of BIM during design-construction management stages. Furthermore, positive prospects of BIM’s potential to be applied throughout the post-construction energy efficiency enhancements can be augmented while highlighting the conceivable successful utilization of BIM during corrective building maintenance management concerns compared to preventive concerns (Motawa & Almarshad, 2013). Moreover, integration of knowledge management systems empowering handling and sharing of respective building maintenance information over the building lifecycle is an inevitable essential during post-construction sustainable performances. Harmoniously, contemporary sustainable developments incorporate advancement of exploiting the aforementioned practices. Congruently, focusing on the building energy efficiency, this article suggests engagement of an Integrated Knowledge-based Building Management System using nD BIM applications (BIM-IKBMS) during the post-construction building lifecycle to advance the implementation of sustainable building performances.
