d2p - office acoustics
The projects aim was to design, plan and realize a parametric spatial structure for the improvement of the office acoustics in the premises of Design-to-Production (d2p) in Zürich. The project started with a kick-off workshop at Design-to-Production. The workshop was used to get familiar with the setting and to measure the reverberation time in order to determine the initial state. It was followed by a first draft phase in the form of an internal competition. In mid-December 2015, nine designs were presented in Zürich, of which Design-to-Production chose three for further development. In the second phase, the three selected designs were revised and further developed by newly composed teams. The focus now lay on construction, material, joining, etc. At the end of the winter-term 2015/2016, Design-to-Production decided to implement one of the three designs.
In summer-term 2016 the realization of the selected design followed with some of the project participants from the winter-term. For this purpose, the design was detailed for the production with CNC-controlled machines and completely parameterized. In September 2016, the acoustic ceiling of more than 100 m2 was successfully installed. A total of 348 modules were mounted in six fields. The modules are diamond shaped within the fields and triangular at their edges. For their frames a total of 1,272 individual parts were CNC-milled. In addition, there are just as many CNC-milled elements to connect these parts, 354 individual CNC milled elements to connect the modules to each other as well as the two-layered substructure.
The sound absorbing materials Lanisor©, which is screwed into the frames, consists of two halves for the spatially placed modules, which is why a total of 609 individual parts were produced with a digital cutter. A room acoustical measurement after installation of the acoustic ceiling resulted in a drastic reduction of the reverberation time, which now lies in a region to be strived for medium-sized offices. This coincides with the subjective impression of the very satisfied users.
