On Tuesday 16th May Paul Jeffries will be delivering a public lecture at Imperial College London entitled ‘Emergence: The development and future of computational design’. The talk will be held in Room 201 of the Skempton Building and begins at 18:30. All are welcome to attend.
For the 2017 Ramboll Leadership Conference in Copenhagen, which took place on the 22nd and 23rd of January, RCD was involved in a collaboration between the Transport and Buildings departments to design and construct a ‘bridge’ installation between their respective stands. We had a little over a month to develop and manufacture the design so timescales were tight and we had several key criteria to consider – the bridge was to support a model train running between the two stands (in reference to the Holmestrand Mountain Station project), it needed to be light and easily demountable enough for us to carry from London to Copenhagen, build in an afternoon, break down in an hour and then return back to London (for later re-assembly in our home office). We also wanted it to form an interactive part of the conference rather than merely being a static display piece.
We approached the project the same way we would any other – pulling together a team with relevant expertise, brainstorming ideas, analysing and developing them. For the interactive element, we realised that business cards made an ideal impromptu craft material and were one of the few things we could rely on most of the attendees to be bringing with them. The decision was thus made to allow people at the conference to leave their business card, folded into a specific 3D form, as part of the bridge’s cladding.

If you’ve arrived at this blog, you will probably have had some exposure to the concept of ‘computational design’. You may also have heard some of the related terms that fall under this heading – ‘parametric design’, ‘algorithmic design’, ‘generative design’ and so on. As computational design is still a relatively young and evolving field the meanings of these terms can be a little vague and are used by different practitioners in different ways. This article presents the vision of computational design that we have in Ramboll and the role that we see it having in the future of the industry. This is what *we* mean by computational design.

Paper presented at the International Association for Shell and Spatial Structures Symposium, 2011. Abstract:
“This paper describes a new method for the form-finding of funicular structures in two or three dimensions using a zero-length spring system with dynamic nodal masses. The resulting found geometry consists of purely axial forces under self-weight, with zero bending moment at nodes for both shells and tension net forms. A real-time solver using semi-implicit Euler integration with viscous damping is used to achieve system equilibrium. By using a real-time solver, the designer is able to alter the gravitational field or apply new point loads without re-starting the analysis, leading to an interactive experience in generating design options. The advantages of this method over existing approaches are discussed, with its successful application in a recent real case-study project also shown.”

With input from several Architectural practices in Denmark we are currently working on an application which models and evaluates alternative commercial tower typologies in real-time, giving instant performance feedback during the early design stages where the most important decisions are made but also when the least amount of time is available.
Evaluation criteria include solar gain, heat loss, structural performance, gross floor area, etc… as well as site specific impacts such as shadow casting of neighbouring buildings. This quantitative performance data (which can be numerically optimised) is then combined with the qualitative aspects of design such as aesthetics, social impact, iconography, etc. when making informed decisions in how to progress the design. Different modes of representation including physical models are also implemented to allow integration with existing tried and tested methods of working.
As the design space is so large at concept design stage, modelling variations in different tower ‘types’ has meant us going beyond traditional optimisation of numerical sliders in parametric models, and as a result this has opened up interesting avenues of research.
Stephen Melville recently gave a lecture to the Architectural faculty of the Technical University of Delft on Computational Design and the practical application of the RCD team’s on-going research to live projects and future directions such as urbanism. The lecture was at the invitation of the high rise unit of the school.
