Consideration of occupant preferences and habits during the establishment of occupant-centric buildings: A critical review

The intelligent operation method is used to optimize the coupling operation of environmental control systems (ECS) in buildings and is significant for mining potential energy savings and improving health and comfort levels indoors. However, automatic operation strategies have high frequency of manual override, which complicates the assurance of the expected operation effect. One of the fundamental rea-sons for this phenomenon is that the automatic operation strategy fails to consider the varying prefer-ences of occupants with respect to the indoor environment and control habits of the ECS. Therefore, considering the personalized preferences and habits of occupants and actualizing intelligent operation are essential to ensuring occupants' comfort and improving energy saving via the automatic operation of the ECS. Based on this concept, this study divided the consideration of personalized factors in intelli-gent operation into two stages: determining occupants' preferences and habits and formulating the oper-ation strategy accordingly. We reviewed research related to these two stages, and extracted the relevant information needed to propose guiding concepts for intelligent operation. Occupants' preferences through physiological parameters and application to intelligent operation strategy were inferred to effec-tively achieve the operation concepts above. The results of this study reveal research gaps and offer guidelines for considering personalized factors in the intelligent operation of ECSs. (c) 2022 Elsevier B.V. All rights reserved.
