HPQ – the physics building of the future

Thanks to rapid progress in the experimental sciences, today¡¯s scientists can study physical phenomena on previously unattainable small scales and short time frames. Under these extreme conditions, quantum effects emerge that often appear to elude human understanding. The investigation of these phenomena, which form the basis for future technologies and entirely new materials, is one of the main focuses of ETH Zurich¡¯s Department of Physics and the interdepartmental technology platforms based at ETH Zurich. A new physics building will be established on the H?nggerberg campus in order to expand this research and prepare for the challenges of the future.

Prequalification and competition
As many as 50 teams consisting of experts from the fields of overall management, architecture and urban planning, civil engineering, and HVAC engineering submitted applications to participate in the project competition. In November 2015, the jury convened for prequalification. The winning entry was by Ilg Santer Architekten, Zurich.

Features of the building
Above ground, the building comprises four laboratory and office floors, a public double-height ground floor and a top floor with building services. The lower floors are split into a main building and a side building, the latter of which houses high-performance laboratories for especially sensitive research facilities. Influences from inside and outside the building could severely disrupt the experiments conducted there or even render them impossible. The research in the underground laboratories places extremely high demands on the building in terms of vibration, electromagnetic compatibility, cooling performance and temperature stability.

A new earth probe field for the anergy grid is also being built below the building, which will make a significant contribution to a sustainable heat and cold supply for the connected buildings on the H?nggerberg. In the 189 earth probes, each of which extends 200 metres into the ground, heat or cold can be stored and extracted as needed. The HPQ building itself will also be connected to the anergy grid.

Ó¢»ÊÓéÀÖ integration and extension of the Flora Ruchat Roncati Garden

The perimeter of the HPQ building will be located in the northern part of the campus, between the HIT and HIL buildings. In order for the HPQ to be built, the Huber Pavilions erected as a temporary solution must be dismantled. The HPQ building will therefore accommodate the exit of the HIT building, making it particularly easily accessible from Wolfgang-Pauli-Strasse. Its glass fa?ade will add further transparency to the campus landscape. According to the jury¡¯s report, the HPQ¡¯s compact structure blends elegantly into its surroundings and allows the maximum extension of the Flora Ruchat Roncati garden as envisaged in the 2040 masterplan. The project of expanding the listed garden will focus on protecting and supporting biodiversity. From the extended garden area, visitors will have direct access to the cafeteria terrace.
