This lecture discusses the architectural design of a pavilion, emphasizing the role of natural light in enhancing the visitor experience. The instructor describes how the entrance invites visitors with rays of light, guiding them through the exhibition. The interplay between light and the building's structure creates a dynamic atmosphere, allowing visitors to perceive temporality and the changing seasons. The design incorporates openings on the north side to maximize the entrance of diffuse light, contributing to the overall ambiance. As the tour progresses, visitors enter the video room, noted as the darkest space in the pavilion, which contrasts with the earlier bright areas. The lecture concludes with a mention of the café, providing a space for relaxation after the exhibition, thereby extending the overall experience of the pavilion.
