ACADIA 09: reForm()

Every year the Association for Computer Aided Design in Architecture (ACADIA) assembles a group of the best and brightest academics and practitioners in the field of architecture with the intent of advancing the knowledge revolving around the use of computation in the field of architecture. ACADIA was formed in the early 1980's for the purpose of facilitating communication and critical thinking regarding the use of computers in architecture, planning and building science.Their annual conference changes venue every year and this year comes to Chicago and, more specifically, the School of the Art Institute of Chicago (SAIC).

An interesting coincidence, as SAIC President Wellington Reiter points out, that as Chicago celebrates the 100th year of the Burnham Plan it hosts a conference of innovators and big-thinkers that Burnham himself would attend were he alive today. The conference, titled "reForm()," explores how architects, engineers, artists and designers are using new HARDWARE, SOFTWARE and MIDDLEWARE technologies to transform the ways in which buildings and spaces perform, act and operate. Mr. Reiter, against the backdrop of a premier art and design school, acknowledged and embraced the exceptionally high level of craft on display in the work presented at the conference, while at the same time issuing a caution to not let the intricacy and complexity enabled by digital tools distract from the issues of the day.

I’m going to attempt to give an objective recap of each of the conference highlights, followed by an interpretation of how the technology presented addresses issues at hand for practicing architects in a world concerned with climate change, renewable energy sources, sustainability and high-performance building systems.

UNSudio and Parametric Modeling

Last night I attended the opening keynote for ACADIA 09 by UNStudio's head of design integration, Christian Veddeler. I write this with the assumption that you're familiar with both UNStudio's work and parametric modeling software.

While I am familiar with and admire their work, I saw Ben Van Berkel speak about the pavilion this past summer, I was intrigued to learn more about their design flow. Mr. Veddeler used the Mercedes Benz Museum as a case study.

The Museum is based on a trefoil knot:

From there the knot was pulled and repeated vertically to create a double helix circulation strategy. Parametric modeling software was essential in keeping the project viable by keeping costs manageable while maintaining a fluid design process.

By applying parameters to elements of the project it allows them to focus on design without having to worry about the means and method of construction as much. For example, a parameter for repeating concrete formwork was applied to the curves and other elements (the entire structure is reinforced concrete). Once that was established they were free to manipulate the design to accommodate the pragmatic constraints that we architects are always faced with; program, square footage requirements, gravity, etc. In this way they weren't waiting until the end to address such things as making certain elements fit into a module so the project budget doesn't spiral out of control.

And don't most architects work in this way? We design a building with little regard to how it's going to get built only to have to go back to the drawing board once the construction bids come back over budget. In my opinion, software tools like parametric modeling are essential for architects wishing to push the envelop of design and construction. It certainly has been for UNStudios.
