Occupant Behaviour (OB) has been identified as one of the most influential factors that impact workplace space usage. In addition

it proven to be one of the key reasons for discrepancies between predicted and measured energy consumption of office buildings. The current interdisciplinary understanding of OB is hardly conducive to an exhaustive conclusion

with many premises and veiled explanations made during the research

design

and management process. This paper aims to review the existing literature that focuses on energy-related workplace OB from Social and Behavioural science and from Engineering science for two reasons. Firstly

to identify the theory

connotation

and application of occupant behaviour in both fields. Secondly

to identify the type of behaviour

triggers of behaviour

and theoretical support for defining the term “Sustainable Occupant Behaviour in Offices (SOBO)”. This review used the PRISMA approach with the addition of snowball papers. The demonstrated results cover three main findings: 1. The four types of OB relevant in workplaces are occupancy

adaptive behaviour

non-adaptive behaviour

and personal adaptive behaviour. 2. Building

environmental

contextual

and personal factors were the four types of influential factors for SOBO. 3. Current theoretical frameworks for SOBO are mainly based on the Theory of planned behaviour (TPB)

the norm-activation model (NAM) and/or the motivation

opportunity and ability (MOA) model. Findings are important for knowledge exchange and synergy processes between both disciplines in future studies.
