Dayun Center Mobile Toilets

The mobile toilets at Dayun Center, represented by the "Space Capsule" and "Hidden Wind Pavilion" public toilets, combine high aesthetics, advanced technology, and user-friendly design, serving as a typical example of urban public facility upgrades.

"Space Capsule" Public Toilet: Integration of Technology and Functionality

The "Space Capsule" public toilet employs prefabricated construction technology, featuring 36 toilet stalls within a 120-square-meter space. The ratio of female to male toilet stalls is 1.57:1, higher than traditional public toilet configurations, effectively alleviating the issue of female queues. Its functional design emphasizes user-friendliness:

• Privacy Protection and Technological Interaction: The exterior wall of the baby care room uses smart glass that can sense light and human activity. When unoccupied, it transforms into a high-definition transparent 3D display screen, showcasing urban culture or public welfare information; when occupied, it automatically frosts to protect privacy.
• Natural Lighting and Ecological Integration: The roof is equipped with skylights to introduce natural light, reducing energy consumption. Surrounding areas are planted with local flora such as bougainvillea, creating an ecological landscape of "one toilet, one scenic view" and enhancing urban aesthetics.
• Diverse Functional Spaces: In addition to regular toilet stalls, it is equipped with a baby care room, a universal toilet (for disabled individuals and families), and a makeup room, meeting the needs of different groups.

"Hidden Wind Pavilion" Public Toilet: Innovative Use of Underground Space

The "Hidden Wind Pavilion" public toilet adopts the design concept of "blending into nature," with its main body hidden underground and only the canopy and U-shaped glass exposed above ground. The roof is covered with soil and grass, seamlessly integrating with the surrounding environment and minimizing interference with the urban landscape. Its technological highlights include:

• Ventilation and Lighting Optimization: It addresses ventilation and lighting challenges in underground spaces through the "Wind Tunnel" (underground ventilation ducts) and the "Light Funnel" (top lighting devices). A 4-meter ceiling height paired with an arc design alleviates any sense of oppression.
• Upgraded Toilet Stall Ratios: It features a total of 41 toilet stalls, with a female to male toilet stall ratio of 2.4:1, further optimizing the experience for female users.
• Balance Between Ecology and Functionality: The underground structure reduces land occupation, while the ground level is covered with greenery, protecting the ecosystem and reducing the visual impact of the public toilet on surrounding activities.

Policy Support and Future Directions

As a core landmark for large-scale events, Dayun Center, in response to high foot traffic scenarios, has revised the "Public Toilet Construction Standards" in Shenzhen, specifying that the ratio of female to male toilet stalls should be no less than 2:1. It is also piloting "tidal public toilets" (which adjust the number of male and female toilet stalls flexibly through movable partitions) to dynamically adapt to usage demands at different times. These designs not only enhance the practicality and technological sophistication of public toilets but also provide a replicable model for urban public facility construction.
