“…They underlined the recommendation of a deeper understanding and interconnection in these fields. Other authors developed studies not only to deepen the knowledge but also to develop new research studies in order to support the different subtasks that are defined by the IEA, represented in Table 2, of the predictability of presence and movement of occupant in buildings [89][90][91]; window opening behaviour in the residential sector [92][93][94] and light switching action [95]; indoor comfort and how it affects occupant behaviour and energy use [94,96,97]; energy-related occupant behaviour surveys [98,99]; etc.…”

Energy-Related Occupant Behaviour and Its Implications in Energy Use: A Chronological Review

Abstract:It is essential to understand how significantly occupants' actions impact the performance of a building, as a whole, in terms of energy use. Consequently, this paper reviews the available resources on energy-related occupant behaviour and its implications in energy use in a building. A chronological review on energy-related occupant behaviour and its implications in energy use has been conducted. As a main existing gap, it was identified by researchers the difference between real energy performance and the one that is predicted during the design stage of a building. The energy predicted during the design stage of a building may be over twice the energy used in the operation stage. Buildings are one of the most energy intensive features in a country. They are affected by the interaction and correlation of several different variables, such as: its physical characteristics, technical systems, equipment, occupants, etc. Therefore, buildings are considered to be complex systems that require a careful and intensive analysis. Moreover, one of the key variables impacting real building energy use is occupant behaviour. The way occupants behave and their motivations are some of the main aspects that need to be considered in a building life-cycle.

“…Based on the TPB, Chen and Knight [19] [10,45], building design robustness [51,52], usability of control systems [53][54][55], social norm, group interaction [19,[56][57][58][59][60][61], personal and cognitive traits (i.e., perceived behavioral control, behavioral intentions, energy saving attitudes) [19,35,46,[62][63][64], and motivational drivers [43,[65][66][67][68]. Langevin, et al [16] observed that behavior sequencing of adaptive actions in office buildings is a complex phenomenon, where multiple behavioral adaptations are sometimes available, and certain interactions are subject to contextual and social constraints instead.…”

This study introduces an interdisciplinary framework for investigating building-user interaction in office spaces. The framework is a synthesis of theories from building physics and social psychology including social cognitive theory, the theory of planned behavior, and the driversneeds-actions-systems ontology for energy-related behaviors. The goal of the research framework is to investigate the effects of various behavioral adaptations and building controls (i.e., adjusting thermostats, operating windows, blinds and shades, and switching on/off artificial lights) to determine impacts on occupant comfort and energy-related operational costs in the office environment. This study attempts to expand state-of-the-art understanding of: (1) the environmental, personal, and behavioral drivers motivating occupants to interact with building control systems across four seasons, (2) how occupants' intention to share controls is influenced by social-psychological variables such as attitudes, subjective norms, and perceived behavioral control in group negotiation dynamic, (3) the perceived ease of usage and knowledge of building technologies, and (4) perceived satisfaction and productivity. To ground the validation of the theoretical framework in diverse office settings and contexts at the international scale, an online survey was designed to collect cross-country responses from office occupants among 14 universities and research centers within the United States, Europe, China, and Australia.

“…Alternatively, if an operable window is left open overnight during the cold winter months, it would lead to unnecessary heating. In either scenario, the occupant behaviors have significant impact on the energy performance of passive designs, which might lead to discrepancies between the estimated and actual measured energy savings of passive designs [73][74][75]. Future work can include investigating and quantifying the correlation between passive design and behavioral measures.…”

Occupant behavior in buildings is a leading factor influencing energy use in buildings. Low-cost behavioral solutions have demonstrated significant potential energy savings. Estimating the behavioral savings potential is important for a more effective design of behavior change interventions, which in turn will support more effective energy-efficiency policies. This study introduces a simulation approach to estimate the energy savings potential of occupant behavior measures. First it defines five typical occupant behavior measures in office buildings, then simulates and analyzes their individual and integrated impact on energy use in buildings. The energy performance of the five behavior measures was evaluated using EnergyPlus simulation for a real office building across four typical U.S. climates and two vintages. The Occupancy Simulator was used to simulate the occupant movement in each zone with inputs from the site survey of the case building. Based on the simulation results, the occupant behavior measures can achieve overall site energy savings as high as 22.9% for individual measures and up to 41.0% for integrated measures. Although energy savings of behavior measures would vary depending upon many factors, the presented simulation approach is robust and can be adopted for other studies aiming to quantify occupant behavior impact on building performance.
