In 1999 brazilian businessman and bibliophile jose mindlin entrusted to his grandson and his friend the mission to create 'the biggest and most important private collection of brasil', located on the university of sao paulo's campus. the library designed by rodrigo mindlin loeb arquitetura and eduardo de almeida joins the ranks of some of the largest libraries in the world, housing 17,000 titles and 60,000 volumes that include some of the country's rarest works. the 22,000 m2 concrete complex will contain an important collection for the institute of brazilian studies, a bookstore, cafeteria, exhibition hall,300-seat auditorium in addition to reading rooms and public halls. an expansive independent roof plane connects the separate structures. a central glass skylight with UV filters and perforated metal plates allows natural light inside while controlling excessive heat gain and glare, and a specially-designed photovoltaic energy matrix that can satisfy all energy needs throughout the day. having a rather large footprint, the architects took special care to design a green landscape to compliment the voluminous structure. trees on site were transplanted and thousands more were planted in the area for the neighborhood to enjoy.
