CUKUROVA INTERNATIONAL AIRPORT ROOF DESIGN DECISION SUPPORT
The perforation of the roof shell structure that accommodates the hotel, car park and two terminal masses were optimized according to their relation to sun. The project area is located in a very hot climate, therefore it was aimed to minimize the summer radiation while allowing as much winter sun as possible. Meanwhile, daylight was controlled for different functions (offices, waiting areas, car parks, transient spaces, commercial areas, etc.) to make sure glare was prevented and sufficient daylight levels were provided.
By manipulating the openings within a 16 x 16 m grid, different levels of porosity have been achieved and this variable composition is used to control the amount of sun allowed inside. To achieve required resolution of perforations, a variable grid of 1sqm. With multiple opening levels has been developed.
A grading scale for the ray falling over the interior surfaces at specific times have been developed to asses the efficiency of opening conditions. The harsh climate of Çukurova differs greatly though out the year. It has been crucial to provide direct sunlight in winter while blocking for the most part in summer.
A custom Python grid written within the Grasshopper environment of Rhino has been used to construct the geometry and Octopus –a genetic solver– has been used for optimization purposes while Honeybee plug-in provided the basic environmental and seasonal data. The optimization was run in multi-dimensions to control and assess the lighting conditions to opening percentages to light falling on the greenery.
The project has been presented in Dijital Tasarım Günleri and CAADFutures conference series. For detailed information about the project, please follow the link to download the paper.
