Dynamic apertures in a building facade provide thermal comfort.
Inspiration from Nature
Bull Kelp responds to multiple variables at the same time e.g, force of water currents and sunlight.
Despite having advanced simulation tools in Architectural practices, we still refer back to vernacular architecture in order to learn from its passive design strategies. These strategies have evolved over centuries of local wisdom and experience. However, they respond to unique climatic conditions. Architects take many parameters into consideration such as wind, sun, views etc. Greater the number of parameters, more complexity there is in design. How can we design one façade which adapts to all climatic variables (wind, ventilation, direct and indirect natural light, shading, views etc.)
Blades of a bull kelp (Nereocytis Luetkeana) respond to two variables at the same time; force of water currents and exposure to sunlight. The blades make it possible by changing their width and texture. Kelp offers perfect case for a façade which can adjust itself dynamically to the changing conditions of climate outside as well as human activity within.
Anatomical diagrams of the kelp reveal that one needs to understand the physics, chemistry and biology of climate before encoding a facade. Research in the field of Responsive Architecture has been growing ceaselessly. Kinetic façades such as WindSwept Responsive Skin, Flare Dynamic Façade, AHR, Re-Skin etc. are some of the most relevant case studies to this project.
A building façade links inside activity with external climatic conditions and adjusts the apertures accordingly. The façade (3) can sense (8) amount of light outside (direct and ambient) and determine the need of light on the inside (6, 15). Its blades move like bull kelp and adjust their width and angle to create apertures (23, 27) and control Venturi Effect (10). Rooms which open into the façade have panels installed in them which have buttons to control various factors manually such as views, warmth, light etc.
