Abstract
ABSTRACT The visual comfort of building occupants may be directly affected by stochastic modulation of shading. In this paper, simulations combined with statistical analysis were used to investigate and evaluate the visual comfort of different seating positions in an office. The dynamic daylighting indicators (UDI, DGP, sDA, and ASE) were used to analyze the visual comfort within an office. The main findings show the following: (1) The DGP and ASE metrics show that the probability of glare in positions near windows is not always the highest. The influence of line-of-sight direction should also be considered. (2) By running 50 simulations, the average value of sDA300/50% was 0.97, and the average value of ASE1000/250 was 11.4%. This shows that the office has good daylighting quality. (3) The optimal visual comfort positions were determined based on four indicators, and alternative options for different indoor occupant preferences were provided. The research results of this paper aim to provide references for the improvement of visual comfort of office occupants.
