Exegesis of building systems through the lens of systems theory: a conceptual paper

Purpose The purpose of this conceptual paper is to explicate the complexities of building systems, their operational structure and functionality through the lens of systems theory. Design/methodology/approach The paper used literature review as a methodology to review existing studies on building systems and systems theory. The aim was to provide a nuanced understanding of building systems and their complexities to aid in the comprehensive exegesis of building systems using systems theory. Findings Using the lens of systems theory, building systems serve as throughputs or channels that receive electricity as a resource input and processes and transform the electricity into output – often in the form of cooled or heated air, light and other energy services – utilized by occupants. As such, occupants provide feedback on the ability of building systems to provide the expected services. This, therefore, informs facilities/building managers on the maintenance needs of the system. Research limitations/implications The illustrations made in the explications of building systems are limited to heating, ventilation, and air conditioning (HVAC) systems, lighting systems and electrical systems. Practical implications The application of systems theory to building systems can inform the design, use, operations and maintenance of building systems. This will enhance the effectiveness, efficient utilization and maintenance of building systems. Originality/value The paper reveals the connectivity and applicability of systems theory to building systems. It therefore serves as a base study that provides a solid theoretical backing to building systems. This will direct future research related to buildings and occupants’ interactions with building systems in their use of energy in buildings.
