Patterns of occupant interaction with window blinds: A literature review

There is no comprehensive consensus about the way people operate blinds or the motivating factors that influence their decisions. However, there is a substantial body of research, encompassing data from more than 50 buildings worldwide, that offers guidance. Patterns of blind use can affect the energy consumption of buildings substantially and therefore energy and daylighting simulations that do not account properly for these blind use patterns will have greater error. An outline for a new more nuanced model for simulation-based blind control is offered. Specifically, this paper reviews the energy implications of blind use, blind occlusion and rate of change from field studies, specific quantitative measures influencing user blind control, investigations into user acceptance of automated blind control, and finally conclusions and knowledge gaps are summarized and suggested next steps for research are provided. Addressing these gaps is critical for the continued progress of the energy efficiency movement.

► We provide an outline for a new more nuanced model for simulation-based blind control.
► We review energy implications of blind use.
► We review blind occlusion and rate of change from 50 buildings in field studies.
► We review quantitative measures influencing user blind control.
► We document knowledge gaps and suggest next steps for blind use research.
