The Museum of Sustainability is gleaming and reflecting as the sun sets over Infinite Island. With a subtle balance between virtual and reality, we takes the unique advantages of virtual space such as infinite volume, zero gravity, multi-layers and voids, as well as many considerations in terms of materials, natural lighting, green plant coverage and more for the feasibility of offline physical buildings in the future. We came up with a concept of flow and conservation of energy, using a cavity-like space to form the entire architecture. The inside of the cavity is connected by an 'energy bridge', through which you can stroll to different indoor spaces, where you can experience an atomic-level sensory experience. Traveling around the entire interior of the cavity, a white space with a blurred sense of boundaries displays different designs about sustainable development, just like nature, where each entity cannot encourage the existence.
