Loop: The Environmental Summer Pavilion 2
This interdisciplinary project involves the team work of the students from the Faculty of Art and Architecture at the TUL in Liberec and the Faculty of Forestry and Wood Sciences at the CZU in Prague under the leadership of Marie Davidová (FACTUinPrague/CollaborativeCollective), Šimon Prokop (CollaborativeCollective)and Martin Kloda (Archwerk). It is the continuation of the project pareSITE: The Environmental Summer Pavilion published here a year ago. Its goal is to evolve the performance of solid pine wood. PareSITE was absorbing the moisture of humid air during the night while evaporating it during hot summer days. The panelling was supporting the performance by its warping – increasing the humid air circulation. This year project took the concept further. The panelling was organised spatially and left and right side of the panels in tangential section was combined. Thanks to this as well as the shape of the structure, the pavilion performed much better.
The concept evolved from origami folded ellipse that was 3d scanned and used as a base for Grasshopper for Rhino 5 model that generated fabrication drawings. The individual pieces for the structure were cut on Hundegger Speed- Cut 3 cnc saw at Eurodach and the panelling on HOMAG Venture 06S 3-axis milling machine at the Faculty of Forestry and Wood Sciences at the CZU in Prague where the structure was also mounted by the students.
The Loop Pavilion served as a meeting point and podium for EnviroCity festival, generating a pleasant environment for its visitors and presenters.
Grasshopper for Rhino 5 Model:
The model was created solely in Grasshopper (anditsplugins) using only two guiding curves in Rhinoceros 5 taken from the 3D scanner. This fact helped the team to work on the structure even before the final shape of guiding curves was found. Due to spatial organization of pannels and the nature of pavilion’s construction there was fair amount of data structure to work with besides the geometry. All the elements were simple planar planks, however the overall shape is perceived as a double curved surface.
Since the shape was considered to be complicated in the terms of statics, the team used a plug-in called Donkeyto analyse possible weak spots in the construction . Simultaneously, the joints were analysed in different constellations of forces to find the optimal positioning of fasteners. Another Grasshopper plugin, Ladybug, was used to estimate Sun’s positions and energy gain on each pannel on the actual site during the period of installation so that the size of panels could become another layer of complexity.
All participating students learned basics of Grasshopper and two of them became fully capable of using the software during the period of the project.
