In collaboration with mudac and designer Nathanaël Abeille, HEAD – Genève organised a workshop entitled “Let’s Hack the Sun”.

Over the course of a Septem­ber week, more than 80 students carried out lumin­ous exper­i­ments, first around the Plate­forme 10 district and in the city of Geneva, using mirrors to redir­ect sunlight towards areas deprived of it. From bridges, balconies, rooftops, bell towers and other elev­ated spots, they reflec­ted natural light into every­day interi­ors and spaces: flats, squares, cafés, gardens and librar­ies. The project cham­pioned the right of city dwell­ers to enjoy sunlight in their living spaces, while show­ing how design can chal­lenge exist­ing urban organ­isa­tion.

By “hack­ing” Geneva’s solar diagram, the students explored a form of life-sized archi­tec­ture powered solely by free and inex­haust­ible cosmic energy. These ephem­eral inter­ven­tions were then gathered into a cata­logue show­cas­ing new ways of light­ing up living spaces in daylight. The whole project culmin­ated in a clos­ing cere­mony held at mudac.
