Current building and planning practices face the issue that, despite their increasing ability to support the collaborative deployment of project teams’ and other stakeholders’ distributed intelligence through concurrent as well as asynchronous processes, at early stages of the building process few tools are available to predict and simulate performance in several key aspects of the project, though the early stages are most crucial in terms of decision making. Available tools that can assess, simulate or predict buildings’ performances in various respects are currently only employed rather late in the design and planning process, due to their complexity and specificity, resulting in optimizing a given solution (post-rationalization) based on “educated guesses” rather than enabling the planning parties to make better-informed decisions beforehand. Another bottleneck while employing such tools is their incompatibility with the extremely dynamic nature of these early stages. Here, options would have to be evaluated quickly, but since the different software packages are not communicating in real-time with each other, designers and planners are not able to keep momentum while importing, exporting and converting large amounts of model data back and forth iteratively. Important methods and techniques that partially address these issues include parametric-associative modeling, computational intelligence, building information modeling, and file-to-factory techniques. The problem remains that these various techniques and methods only offer partial solutions towards integrated, performance-oriented design and need further developments and non-prescriptive linkages in order to achieve the flexibility and fluidity which are necessary to support true design exploration, especially in the early stages where divergent rather than convergent thinking is prevalent, and standards and other conventions tend to be overly restrictive.

In this workshop we aim to discuss these issues and possible approaches to overcome them, focusing on building design but considering the larger context within which buildings perform and upon which they have an impact. We aim to relate the need for detailed information modeling and exchange for design validation and documentation with modeling approaches that support the dynamic nature of design at the early stages and are able to leverage the strengths of rules and types as well as supporting “expandable rationality,” innovation and emergence. We aim to identify concrete R&D steps that can alleviate some of the issues identified above.

The workshop will bring together both invited and other interested researchers, practitioners and developers to brainstorm and discuss on the issues and objectives presented above, with the goal of identifying concrete R&D steps. Participants are invited to submit a position paper or a brief description of research results that can shed light on these issues or suggest possible (partial) solutions. Some will be selected for short presentations. Papers and presentations will form the bases for discussion.

Expected output
We aim to identify concrete R&D steps that can alleviate some of the issues and help to achieve the objectives presented above. It is also the intention to publish the workshop results in a joint publication, possibly a special journal issue.
