Since the end of October 2013, a total of 2,403 moving layers, over a total area of 1,000 square meters, have been in use, both for daylight regulation and the production of almost 1.4 megawatt hours of clean, green electricity: enough to meet the annual consumption needs of about 500 households a year.
In his museum buildings, Renzo Piano experiments in particular with incidence of light in order to be able to regulate daylight in the exhibition spaces.
