Italian firm Giovanni Vaccarini Architetti has designed the new Headquarters of the Swiss Société Privée de Gérance (SPG), built on Route de Chêne, at the gates of the historical center of Geneva. The work involved the conversion and extension of the existing building, starting with a glass façade that meets the need for solar shading in the interiors while achieving maximum visual permeability.
This façade also improves the acoustic and thermal insulation performance of the building: the double skin allows the envelope to be naturally ventilated and the perimeter ventilation system, combined with the internal forced ventilation system, reduces overall energy consumption. The steel structural elements on the façade, produced by Stahlbau Pichler (a specialist in the sector) produce a modular rhythm and the reflections on the glass shading panels give the project a particular "material weight."
