Abstract
The planning of commercial exhibition halls is a unique space planning problem, mainly due to the nature of these events, as they last for a short period of time and involve a large and diverse number of stakeholders, which demands a quick and highly flexible design process. Additionally, there is the challenge of the large number of visitors that attend these events and whose comfort is a priority for the event’s success. Using traditional approaches is both time consuming and doesn’t allow for creative solutions due to the time constraint. The use of computational design for automating the space planning problem is an area of research that has been ongoing since the 1970s. However, there are two main obstacles found for applying computation to solve this particular problem. First, the space planning problem has no definite optimal solution and solving it usually relies on the experience of the human designer and his intuition. The second issue is that in reality the space doesn’t only contain static walls and booths but also dynamic visitors whose interactions and behavior affects other visitors and is also affected by the layout arrangement. This research aims to introduce a framework that utilizes parametric modeling for representing the commercial exhibition layout and agent-based simulation for evaluating visitors interaction in exhibition space. The computational representation of both the static and dynamic elements of the space planning problem provides an opportunity for producing a large number of spatial scenarios in a very short time and the possible evaluation of these scenarios using the critical metric of visitor experience.
This research starts with an overview of and an analysis of the design problem of the space planning of commercial exhibitions. Then, the computational tools and techniques used in space planning automation and evaluation of the behavior of human occupants in space are explored. The approach of using rectangular subdivision for the parametric modeling of the space planning problem is utilized for creating an algorithm in Grasshopper in Rhino for the automatic creation of orthogonal exhibition layout plans. Then PedSim Pro, an agent-based modeling add-on to Grasshopper is used for the simulation of visitors’ behavior in a number of layout scenarios output from the parametric model to evaluate movement patterns of visitors, their foot traffic and individual booth exposure. Finally, a framework for utilizing computational design techniques for the space planning of commercial exhibition halls is proposed.
