Çift cidarli cephelerin ısıl ve gün ışığı performansları; bir ofis binası örneği

Depending on the climatic region, double-skin facade structures can aid in achieving human comfort and save building energy through controlling the interaction between indoor and outdoor environments. Sustainable designs aim to maximize admitted indoor daylighting to help reduce energy consumption. The study analyses different variables of double-skin facades that may affect the thermal performance and daylighting of the building. The main objective is (a) investigate the thermal effect in office buildings (b) analyze admitted daylight into the building (c) propose a flexible model that contribute to the overall performance and formation of the building façade. The framework consisted of investigating an office building located in Eskisehir, Turkey. The research evaluates performance-based computational simulations using Rhinoceros, Ladybug, and climate studio combined with Energy-Plus. The assessment focuses on the various characteristics of the façade, such as; façade distance, solid to void ratio and rotation degree. Four different façade iteration were designed and tested on all four façade directions of the office building. The results of all four different proposals have reduced the highest radiation value indoors significantly in both seasons. The highest radiation reduction reached 32.12% in summer and 22.82% winter. The highest increase in daylighting reached 83.78% in summer and 45.58% in winter. The results confirm that the use of wider panels provides lower concentrated solid areas of panels and admits more radiation and daylight levels into the building.
