Le Rosey Concert Hall
The campus architecture of Le Rosey, an international boarding school in Rolle, Switzerland, consists of a dozen buildings with a stately character. Within this context, the competition for a new philharmonic hall and arts center for the well-known school raised the question: how can architecture establish a complimentary relationship between the old and the new—a dialogue between tradition and modernity? Last but not least, how can one make a highly sustainable, naturally ventilated 900-seat concert hall?
Our strategy proposed a low, flat dome—a metal envelope that emerges from the landscape, shining in the sun by day and reflecting ambient campus light by night. This dome provides a common denominator for the various parts of the program. A place of meeting and interaction, it is situated at the base of the keystone-shaped area formed by the existing buildings. more
Despite a tight budget, the concert hall provides a world-class auditorium that responds to stringent sustainability requirements while welcoming the world’s most prestigious orchestras. The program includes the concert hall, adaptable for film projection, lectures, and amplified music, as wells as a black-box theater, conference rooms, rehearsal and practice spaces, a library and learning center, restaurant, café, student lounge, and other amenities.
Exceptional measures were taken to meet the building’s acoustic and sustainability goals. Natural air taken from the outside is channeled and used to ventilate the concert hall and other parts of the building, 85% of which is naturally ventilated, creating one of the few naturally ventilated concert halls of this prominence in the world. Locally-sourced, non-toxic recycled OSB was used for wood finishes to meet acoustic, economic, and ecological requirements.
Programs including offices and ateliers are located on the periphery to bring in daylight and provide natural ventilation directly through operable façades opening to planted grounds or upper-level balconies. Roof overhangs, exterior fabric blinds, and double glazing minimize the effects of direct sunlight and reduce energy costs. back
