Gizelle Javidan and Shyam Chand argued that computational design has stopped being a way to draw complex geometry and become a way to manage it, connecting design, performance, fabrication and access into one decision-making process for a façade that can actually be built and maintained.
Javidan leads WSP’s computational design team within building enclosures and co-presented with Chand, who leads the façade access team. Their framing of “Smart Façades, Smarter Access” was pointed: computational design is valuable not as a tool for creating complex geometry, but as a framework for connecting design, performance, fabrication and access into a single decision-making process.
The problem, Javidan said, has moved. Twenty years ago designing a complex façade was the challenge; today the software, engineering tools and computational design can generate almost any geometry you can imagine. The real questions now are different, can we build it, access it, maintain it, make it perform, and make it affordable?
And a façade is a peculiar place to ask them, because it is not a building element but an interface, between architecture, engineering, construction, operation and human experience, where disciplines collide. Architects want beauty and design freedom; engineers want performance and efficiency; contractors want simplicity and buildability; owners want value and long-term return. Her key line captured it: the façade is not one problem, it is four competing problems trying to become one solution. Computational design earns its place by managing that complex system rather than just drawing the shape.
The buildability method was a worked example on a doubly-curved, domed envelope. Step one decodes the geometry, splitting the surface into transitional, single-curve and double-curve zones to understand where the complexity actually sits. Step two rationalises it with a Gaussian Mixture Model that clusters the thousands of panels into a manageable number of families by shape. The framing on the slide was the whole argument: the geometry is not simplified, it is interpreted, classified and transformed into a buildable system, with performance studied in the same workflow rather than checked afterwards.
Chand’s half took the same rigour to the part usually left until last: getting to the façade to clean and maintain it. Movement across a complex skin, anchor-point positioning and abseiler routes were designed in from the start, with cradle and monorail systems integrated into the shading structure. The access strategy was tuned to the façade’s own angle, an anchor point and walkway where the surface is near-vertical, adding diverter rails as it tilts past sixty and toward ninety degrees, and resolved against the ergonomic and anthropometric limits of the people doing the work.
The shared conclusion was simple: a smart façade is only as good as your ability to build it and keep it working, and both are computational-design problems that belong at the beginning of a project, not the end.
