Fwd: PUARL Symposium

Second PUARL International Symposium 2011

Generative Process, Pattern Languages, and the Urban Challenge
University of Oregon Portland – October 28-30, 2011

Abstract deadline extended to: July 30, 2011

In the Portland Urban Architecture Research Laboratory PUARL we attempt to induce
and integrate wholeness and sustainability into the urban and architectural design process
by conducting basic and applied research. We work on practical urban and architectural
projects within the region as well as internationally.

Following the successful completion of the first International PUARL Symposium in the
Fall of 2009, and its publication in 2010, we are pleased to announce the next conference
in this series, on Generative Process.

Generative Design, an applied topic within generative science, tries to understand and
conceptualize the world and its complex structure as a generative process: It
approaches design problems by formulating limited parameters, principles, and rules
that interact with each other to create richness of life and behavior, and limitless
variation of form, shape and place. Generative design spans a large range of
applications from digital computer generated production and algorithms that generate
designs and ornaments to communal design, generative urban design, and building
efforts expressed in generative codes. As Christopher Alexander observes: “Generative
Codes evolved from Pattern Languages but they are much more sophisticated
generating systems. A generative code is a system of unfolding steps that enables
members of a community to create a healthy urban neighborhood or urban district. The
steps are governed by rules of unfolding that are not rigid or limiting, but depend on
context, and on what came before. The rules operate organically and mimic nature’s
process of unfolding an organism or landscape.”

Generative process explores the world as an emergent process at several levels of scale
and with regard to different modes, including but not limited to physical, artistic, musical,
and social cultural as well as economic themes. At the urban design, planning and
architectural level, communal generative processes are of specific interest in this
- How can generative processes and generative (urban) design help to solve
some of the current Urban Challenges that we face in our cities, neighborhoods, streets
and parks.
- And how can interdisciplinary generative processes help to create and
maintain working neighborhoods and sustainable and whole communities, urban districts
and livable streets?

Generative Process
The nature of generative processes in the natural and human world will be investigated
and their usefulness and appropriateness for the design process will be explored.
Generative design processes will be investigated through case studies in urban design,
architecture and building, and other disciplines. Theoretical explorations and experimental
projects are also welcome for presentation.

Patterns and Pattern Languages
While generative processes are being explored for application in design, planning,
building and development processes, patterns and pattern languages are a backbone of
the pattern language approach. Recent advancements and refinements of application in
design, planning and building processes are core issues in this conference, including
pattern applications in multiple disciplines.

The Urban Challenge
The urban challenge has become much larger in our lifetime with half of the increasing
world population living now in cities. How can generative processes and pattern
languages help to solve some of the contemporary urban problems will be one key
