Fixed shading devices (SDs) are still used as an essential and useful element in architectural design. Even with minor changes to be made when designing these devices, the energy performance of a building, especially in hot climate regions, can be significantly increased. In contrast to studies using one or a few parameters, this study aimed to make a comprehensive evaluation by considering more parameters simultaneously to determine energy-efficient fixed external SD scenarios that can be used in office buildings. This approach increases the accuracy of the results in terms of providing trade-offs. This study also aims to fill the gap of the research on SD strategies in Turkey. A total of 1485 scenarios were created with fixed external SDs (overhangs, horizontal and vertical louvers, and egg-crate variations) using the parameters of direction, glazing type, window-to-wall ratio (WWR), SD depth, and slope. Primary energy consumption values of all scenarios were calculated with the DesignBuilder software. Results were discussed according to the impact of each parameter on energy consumption and evaluated through descriptive statistical analysis. As a result, energy-efficient scenarios were determined. The best scenarios obtained for each SD type reduced the cooling energy consumption by between 37% and 49% compared to the no shading scenario using high-performance glazing type and by between 73% and 78% compared to the no shading scenario using low-performance glazing type. The total annual energy consumption was reduced by approximately 33% and 70%, respectively.

固定阴影设备（SD）仍然是建筑设计中必不可少的有用元素。即使在设计这些设备时需要进行一些小的更改，建筑物的能源性能（尤其是在炎热的气候地区）也可以显着提高。与使用一个或几个参数进行研究相比，本研究旨在通过同时考虑更多参数来确定可用于办公大楼的节能固定外部SD场景，从而进行全面评估。这种方法在权衡取舍方面提高了结果的准确性。这项研究还旨在填补土耳其关于可持续发展战略的研究空白。使用方向参数，使用固定的外部SD（悬垂，水平和垂直百叶窗以及蛋箱变化）创建了总共1485个方案，所有场景的一次能源消耗值都是使用DesignBuilder软件计算得出的。根据每个参数对能耗的影响讨论了结果，并通过描述性统计分析对其进行了评估。结果，确定了节能方案。与使用高性能玻璃的无遮光方案相比，每种SD类型获得的最佳方案将冷却能耗降低了37％至49％，与使用低性能的无遮光方案相比，降低了73％至78％玻璃类型。年度总能耗分别减少了约33％和70％。
