The document discusses concepts of sustainable building design through maximizing natural light and green infrastructure. It provides several examples of buildings that effectively use natural lighting and green roofs. Specifically, it discusses how (1) natural lighting reduces energy costs and improves well-being, (2) green roofs conserve water and create habitats, and (3) bio walls beautify buildings while improving air quality and reducing temperatures. The examples, including the California Academy of Sciences, demonstrate these sustainability strategies.
