Digitalisation within the facilities management (FM) sector has great potential to positively impact the environmental performance of the architecture, engineering, construction and operations (AECO) industry. Currently, the domain suffers from poor data integration with other disciplines and earlier life-cycle phases. Though solutions which address the interoperability issue are replete in the literature, there remains no comprehensive alignment. This domain review paper synthesises the key literature around digitalisation within FM. In doing so, it outlines a broader working definition of FM, identifies key subtopics and gaps in knowledge and recommends a direction for future research contributions.

Demand Side Management (DSM) programmes promote energy flexibility, cost reduction and resilience in both grids and buildings, which can be supported by integrating Building Information Modelling (BIM) and Building Automation System (BAS). Despite recent advances in the field, research to date remains limited in defining data requirement structures and interoperable approaches to exploit the potential of this integration. This paper defines a set of exchange requirements (ERs) to support DSM using BIM and BAS domains. The definition of these ERs is the foundation to create a common data model that enables context-aware DSM optimisation strategies.
