There is no comprehensive consensus of the control patterns people op::rate shadings or the motivating factors that influence their decisions. Patterns of shading devices use can affect the energy consumption of buildings. Therefore, this study aims to analyze shading device usage patterns based on the physical factors that can affect occupants behavior. First, control patterns of indoor shading devices in apartment buildings were monitored by taking pictures. Next, frequency of shading device use together with their shading portions was analyzed based on two physical factors such as window orientation and floor level. The results showed that about 35% of the monitored apartment buildings utilized indoor shading devices. Also, the south-facing apartments were more dynamically used than their east-facing counterparts. On the contrary, there was no general trend in regards to the shading operation patterns.
