London- and Delhi-based design firm and research platform rat[LAB] unveiled their concept for a algorithmically-designed facade system that can adapt to different climatic conditions. As a demonstration, the team has digitally applied the Cellular Morphology Façade, consisting of 917 unique cells made of 5,392 non-identical surfaces, to an existing building in New Delhi. A large-scale prototype of the design has been exhibited at at Alliance Francaise de Delhi as a part of ’20 under 35’ Exhibition in February 2015.
The building’s facade retrofitted with a new skin consists of multiple hexagonal components controlled through an algorithm that alters its density and attraction. Six functional zones were used as attractor points and the first parameter that affects the configuration of the facade. Different local angular variations help redistribute sunlight across the envelope and change visibility into and from the interior space.
The team, led by architect and rat[LAB] co-founder Sushant Verma, conducted a solar radiation analysis and concluded that, compared to the old facade, the new one redistributes solar insulation across the building in a much more controllable and optimized way. Using digital prototyping techniques, the team has produced an envelope consisting of 917 unique cells.
