This years BIM module addressed the topics parametric design, component modeling techniques, surface rationalization, model analysis and computation as well as data processing and representation on a case study for a building envelope.

The module kicked-off with a lecture series by Prof. Marco Hemmerling, covering the major aspects and best practices of the digital planning methodology that interlinks all processes related to design, planning, execution and operation of a building.

During a four-day BIM workshop, held by Andreas Dieckmann from RWTH Aachen, the MCDC students developed a design concept for one of the facades of a fictional building set on a fictional site that is based on a coherent Building Information Model. The building was supposed to be developed as a simple volumetric mass based on a given footprint and number of stories. Each participant carried out an individual design concept for the building’s south facade, taking into account the site and design conditions (e.g. solar gains, vistas etc.). The façades consist of glazing elements and shading devices, where applicable. A major aspect of the workshop was the optimization of the design throughout the process by testing variations of the initial idea (e.g. facade, interior, spatial layout, construction, energy concept, materials…). The final results show a broad range of façade typologies and tectonic solutions for the chosen site.

The ‘parametric’ brick is able to protect or to expose the building and its users. Based on the European ‘brick stone expressionism’ the idea is to use ‘bricklike’ façade structures – able to turn out or inwards and expand or retract in length forming larger or smaller openings controlling the average amount of sun light radiation per year passing through the facade. Once calculated, the bricks will stay passive giving unusual views from inside to outside and vise versa.
