A field investigation of the intermediate light switching by users

Data analysis and stochastic modeling of lighting energy use in large office buildings in China

“…Yun et al [8] demonstrated that outdoor illuminance was not a statistically significant factor affecting indoor lighting energy, rather the operation of lighting was more strongly correlated with the time of day. Additionally, other studies have also found that in offices without daylighting control, occupant use of electrical lighting was more dependent upon whether the room was occupied, than the outdoor illuminance [9][10].…”

“…This fact has caught the attention of practitioners, researchers, and policy makers. Studies have shown that the two main factors affecting lighting energy use are outdoor illuminance and occupant behavior [2][3][4][5][6][7][8][9][10]. From field studies and computer simulations, it has been concluded that lighting energy use is correlated with outdoor illuminance.…”

“…The analysis methods and conclusions from these studies [2][3][4][5][6][7][8][9][10] provide some baseline understanding of the role of illuminance on lighting energy use in buildings. However, due to limitations associated with the building layout and limited measured data, the complete picture of lighting energy use and the influencing factors, remains unclear.…”

“…The above studies [2][3][4][5][6][7][8][9][10] on lighting energy use were mostly focused on small office and residential buildings, with the research findings greatly dependent on building layout and daylighting control systems. The analysis methods and conclusions from these studies [2][3][4][5][6][7][8][9][10] provide some baseline understanding of the role of illuminance on lighting energy use in buildings.…”

Occupancy measurement in building: A litterature review, application on an energy efficiency research demonstrated building

“…Measuring the energy efficiency of buildings and its confrontation with the current building energy simulations now faces knowledge of what is commonly called "occupancy" [1][2][3][4][5][6][7][8][9][10][11][12]. Indeed, the influence of user behaviour on building energy consumption is significant and is increasing as building performance is high.…”
