The Effect of Parametric Design on Designing Performative Facades

In a simple definition, architecture was aimed to inhabit human inside a space that covers him from wild extreme environmental conditions. During the centuries, it developed and achieved higher levels of complexity and advancements in technology, space organization, style, material assembly and so on. If the first generation of digital modeling programs allowed designers to conceive new forms, a new breed of digital techniques is today discussed for their ability to allow these forms to be controlled and realized. With the advent of digital technologies and the ability to conceptualize, express and produce complex and non-standard forms, the novel direction for supporting performance- based design are beginning to emerge. Parametric design as a relatively new method in architecture based on relationships and rules using the computer can help for achieving performance-based design.Development in computational design and simulation applications are providing methods to improve current design practices, since the uncertainties about various design elements can be simulated and studied from the design inception. Building performance simulations aid in investigating design options and the overall building performance and are an integral part of the design process for energy efficient and high-performance buildings.Since the façade is one of the most significant contributions to the energy budget as well as the comfort parameters, it is important to focus more on it. By making the facades more dynamically responsive to the environmental conditions they can fit better to the various conditions and therefore supply better comfort for the occupants.In this work, the method for designing an adaptive façade for the ARI-3 (Advanced Research and Innovation) Building in ITU, Maslak campus, Sariyer, Istanbul, Turkey will be present. Parametric modeling is developed in Grasshopper, a plug-in for Rhino 3D, using DIVA (plug-in for Rhino and Grasshopper) for daylighting simulation. The main objective of the process and algorithm is to evaluate the performance of an intelligent adaptive façade, composed of a series of kinetic louvers that actuate in response to dynamic daylighting.
