The Solar Library and Energy-Optimized House (called Solar LEO House), situated in Youth Park in Taipei, has been constructed based on environmental protection principles. The Solar Library is a two-story box-like house with a simple, minimalist, modern appearance. The form was obtained through computer programming analysis to minimize the energy use of electricity. The design was a collaboration between Bio architecture formosana and HAND initiative who brought in German energy saving building concepts and expertises.
