Abstract: Background: The global environment is gradually deteriorating, environmental problems are beginning to attract attention, urban green area and water surface area is getting smaller and smaller, but the roof as a side of the building is often neglected, is a piece of space environment in the city has not been fully developed. The form of green roof can take into account the architectural landscape, extend the life of the building, and also improve the urban ecological environment. Based on the consideration of ecological environment and development space, the roof of the School of Mechanical Engineering at Jiangsu University of Science and Technology Changshan Campus, which will be officially opened in 2020, can be used as a rooftop garden to create an activity space for teachers and students that optimizes the rooftop environment and extends the life of the building.Research Objective: This paper is designed from the needs of the audience, combining ergonomics for space partitioning and proposing design priorities. By analyzing the audience's needs for different functional partitions, the way of interaction between the audience and the environment in the space is designed to solve the problem of sustainable utilization of rooftop resources.Research Methodology: This paper establishes a theoretical knowledge system by studying the development history of rooftop gardens and basic knowledge such as design principles, analyzes the environment and audience population, and combines ergonomics to focus on functional design and related details. A questionnaire survey was conducted among school teachers and students. 90.1% of the audience considered the aesthetic appearance of the rooftop garden to be the most important, followed by function and quality. 96.9% of the audience wanted a suitable space for rest and conversation in the rooftop garden, followed by a reading and learning space and a viewing platform.Findings: The design takes into account roof safety, ergonomics, and the usage needs of campus students and faculty, and divides the roof plan into five zones to create a spatial environment with different functions. Finally, based on ergonomics, the design of tables and chairs for the roof garden, the design of interactive landscape facilities and the design of rainwater retention performance are combined with suitable human size parameters to create a sustainable roof space with both aesthetics and multifunctionality around the above design focus. Specific design elements are as follows.(1) The table and chair area provides an open space for people to rest and study. It is made in the form of a tree table. The shape is transformed from a gear form to a more rounded and gentle organic form. The shape of the table and chairs match the physiological curve of the human body, which is ergonomic and feels natural and comfortable in the hand, and the size of the chairs reach 90% and 95% of the population size data.(2) The interactive landscape installation in the entrance area is a circular gravity-sensitive swing, with curves that fit the human body and sensing lights that allow teachers and students to visualize the flow of people in the garden. It makes the interaction between people and the environment more intimate, allowing users to generate and transmit emotions, and improving fun and playability.(3) Design three water storage tanks for storing water, with specifications set at 1 m×1 m×0.5 m. The storage tanks and control boxes are set on the top outdoor ground and designed as an automatic irrigation system that can collect, purify and reuse rainwater, allowing the roof to solve the problem of rainwater resource utilization while improving ecology.Significance of the study: The rooftop garden is significant in that it makes use of the space resources that have been set aside to green the campus and improve the ecological environment on the one hand; on the other hand, it provides space for teachers and students to engage in leisure activities, regulates people's psychological state and improves their quality of life. It improves the quality and value of the building and the ecological environment of the city at the same time.
