Abstract: The "Pavillon System" is a means of urban renewal, a service facility with integrated functions such as aesthetic education, resting Shelter, outdoor furniture, etc. It is a kind of artistic urban infrastructure. In 2021, The author was invited by Shanghai Urban Public Space Art Season(SUSAS) to design and construct a "cycling pavillon " in the Lingang Future Community Sample Exhibition, as a demonstration project in the new area of Lingang, which aims at the low-carbon system of future living and green city construction. One of the demonstration projects in the new area of Lingang with the goal of a low-carbon system for future lifestyle and green city construction.This design attempts to reduce carbon emissions with bamboo structures from the beginning, and then considers low carbon green construction in the production and processing of materials, transportation of materials and equipment, the construction process and building operation. Bamboo matrix fiber composite is a new material with structural performance equivalent to FRP, higher outdoor weather resistance than preserved wood, and close to the price of preserved wood, which has the value of promotion.In the face of the completed site, the building foundation of the cycling pavillon adopts a minimal approach to the ground pavement to intervene in the site, abandoning the traditional need to pour concrete slabs on site for the foundation and using I-beams as the foundation anchored to the ground, reducing carbon emissions generated during the construction and material production process. This construction method allows the cycling pavillon shaded roof to withstand typhoons in the summer in the port area, and gives it the ability to be rebuilt off-site after demolition, a repeatable feature that extends the life of the structure in a rapidly growing urban area and reduces the carbon footprint of the demolition process.The construction process is highly efficient and can reduce carbon emissions by more than 40% over the life cycle of an assembled building, which is an important technological path to achieve "peak carbon" and "carbon neutrality" in the construction industry. The construction process also has a good dust reduction effect, saving water, electricity and other energy, while achieving the original purpose of building energy saving and environmental protection.The cycling pavillon is built in an assembled manner, enabling rapid construction in 60 hours. Thus, it is combined with the built-up site in a light intervention manner. Material utilization is improved through material optimization and reuse of components. With two types of parking, "interlocking" and "hanging", it can meet the different needs of daily use and professional cycling competition. The design concept of space-time movement stable structure is inspired by the trajectory of the wheels, and the mechanical movement of the bicycle in four-dimensional space-time is fixed in three-dimensional space to form a stable structure.The design of the cycling pavillon starts from the demand of urban public space life, in order to provide a possibility of public communication while solving the demand of small and micro space of public life. Through the distinctive artistic image of the space itself, the balance between artistry and practicality is achieved,More importantly, through the use of high-strength bamboo fiber materials, a low-carbon artful infrastructure construction model is explored
