Solar control devices have a significant effect on providing indoor thermal comfort by minimizing annual energy costs in hot-dry climates. Within the scope of the study, the settlement pattern Şilbe 1st Stage Mass Housing settlement located in the city of Diyarbakır, which is located in the hot dry climate zone, was discussed. Horizontal-vertical solar control devices were placed on the transparent surfaces in east-west and northeastsouthwest directions, which give optimum results due to the shadow effect, by means of the DesignBuilder Simulation Programme, and the effect of annual heating and cooling energy load expenses was examined.This study aimed to examine the effect of solar control devices on energy saving in hot dry climate regions.As a result of the study, solar control devices placed in both east and west directions provided a significant decrease in annual energy costs. In addition, the types of solar control devices (horizontal or vertical) used had an impact on annual energy costs.As a result of the analysis, it was determined that horizontal solar control devices should be preferred in hot-dry climate regions. This study will be a guide for the studies carried out within the scope of energy efficient structure design of solar control devices.
