Abstract-Sun is the significant criterion that plays the most important role in architectural design. The sun's heat and radiation interact with the designed components of form and façade. These shading elements exhibit different expressions according to the structure orientation and the sun position. According to the climate of structure's location, the expressions are being used to better respond to the environment in sustainable architecture. In order to get to this point, it is very important to calculate the shading geometry and solar energy during the day and to provide more suitable systems in glass and window designing. According to this, in order to arrive at more suitable shading systems by supporting MATLAB program, the software is written by taking the previous works as basis and closing some of their mistakes. According to the climate data, this program takes the plan drawings of window's zone and some other information of window, the annual shading simulations are presented. Due to these simulations incident solar radiation of window, essential element of cooling load increasing in summer calculated. Furthermore window designing will be occurred by these simulations. So for the future works the user can import the glass or other datum of window or shading monument to design more efficiency.

Double-skin facade systems are essential to minimize energy losses and provide maximum efficiency from the energy used. In this study, a corridor-type double-skin façade system was applied to the south front of the fifth floor of a five-story office building designed in Alanya, Antalya, in the hot climate region of Turkey. In addition, the usefulness of double skin facade systems in hot climate regions is determined by evaluating thermal and energy performance comparatively over three different parameters: material type, cavity widths between the two walls, and window opening ratios on the facade. This research is aimed to raise awareness around the comparative use of brick walls, wood, and composite panels with opaque qualities within the scope of material, with 1 m, 1.5 m, and 2 m as the width of the gap between the two walls. For all materials, thermal performance and energy performance decreased as the window opening ratio on the facade increased and as the cavity between the two walls decreased. However, worse performance was observed in the use of wood because of the low U-Value compared to the single-skin façade (SSF) building. In contrast, excellent performance was seen in using brick walls and metal panels compared to the SSF building, and overall, the metal panel showed the best performance. In the metal sample with a WWR of ten percent, the most significant reduction (27%) in annual cooling load can be seen.
