YOUKOSO

In Japanese, the term Youkoso refers to the polite greeting of guests, the welcoming of guests. The team led by Bollhalder + Eberle and Burkard Meyer Architekten chose this thematically appropriate title for their second-ranked competition entry in the «PORTAL UZH» competition – new research and teaching building for the University of Zurich on the Irchel campus. With its portal building Y10, this key project of the campus renewal is intended to provide orientation and space for students, visitors and staff. The Y51 laboratory building and a plinth building complete the ensemble of buildings. In the opinion of the jury, the design has succeeded in making an architectural gesture of welcome: «The finely scaled portal architecture signals openness and approachability in a pleasant way.»

The main façades developed by the Lüchinger+Meyer façade planners involved are representative and harmonised with the building functions. A wooden mullion and transom façade with a very high degree of transparency clads the Y10 arrivals building. Thanks to the holistic construction with its high spatial content, the accessible deep balcony bands and the generous façade openings create a pergola-like intermediate climate. We are happy to quote the jury report: «The delicate colonnade façade of the portal, characterised by many columns, expresses human scale and modesty.»

The laboratory façade has fixed glazing due to its use and the requirements of the operation. The proportion of transparency is kept low thanks to the green parapet strips on the outside and the vertical ducts in the façade. The extensive greening on the façade creates a cooling microclimate and provides passive shading for the glazing. The jury praised these measures for minimising cooling requirements.
The development and details of the main façades are derived from the technical context and optimised for cost-effective implementation, efficient assembly and a minimal carbon footprint (construction and operation).
