The double "bamboo tower," located near the largest river in Changsha city, Hunan Province, China, showcases a thoughtful design that addresses both environmental conditions and urban needs. The building features a dual structure that allows for optimal views of the river while managing the sunlight that floods the area. The design concept focuses on enhancing the relationship between the building and its surroundings, creating spaces that are comfortable for users while integrating nature into urban life.

Sunshade System

A notable aspect of the tower is its sunshade skin system. This system is adaptable, allowing sections to fold away. When opened, the sunshade provides clear views of the river, making the most of natural scenery. Closed, it effectively shields occupants from the sun's rays during the hottest parts of the day. This flexibility helps residents enjoy both light and views according to their needs and the time of day.

Connectivity with Green Belt

The design connects the tower to a green belt, encouraging easy movement for pedestrians. This integration supports outdoor activities and connects people with nature. Occupants experience multi-level views, taking in both green spaces and the river. This relationship creates a blend of urban living and natural beauty that enhances the overall environment.

Climatic Responsiveness

The design considers the climate of Changsha, adapting to seasonal changes. Temperatures rise above 26 °C between May 15 and October 15, making effective shading a necessity. In winter, light access becomes important, as temperatures drop below 10 °C from November 15 to March 15. The sunshade components adjust to optimize warmth during colder months. This approach helps maintain comfort inside the building throughout the year.

Natural Ventilation

Wind simulation studies indicate favorable air movement around the structure. The form of the tower enables good natural ventilation, helping to regulate temperature without relying heavily on cooling systems. This strategy not only increases energy efficiency but also ensures that living conditions remain pleasant for residents.

The final design detail includes a flexible sunshade that enhances the building's visual character. It is not just about function; it adds to the tower's appearance, creating a surface that changes throughout the day as the light shifts, contributing to the dynamic experience of the space.
