Architectural Design of Universities for Green Campus in Guangdong-Hong Kong-Macao Greater Bay Area and Singapore: A Comparative Aspect

College campuses need the most attention to build. This article is relevant, as the design of green campus buildings is one of the essential forms of the good ecological development concept that can best reflect the sustainable development of university campuses. The total energy consumption of school buildings is second only to that of all kinds of office buildings and accounts for a considerable proportion of the total. The purpose of this study is to investigate the typical campus buildings in Singapore with mature development of green campus buildings to provide a reference for the study of architectural development in the Guangdong-Hong Kong-Macao Greater Bay Area with similar climate adaptability. This paper uses Ladybug Tools to conduct quantitative analysis and compares the Greater Bay Area with Singapore, which has similar conditions, to try to summarize the universal design strategies and models suitable for it. It was found that the university campuses in the Greater Bay Area have a better development in the greening of building courtyards and building roofs, while in the greening of building platforms and building walls, it still needs to carry out more technical practice. It was established that among all kinds of designs on the green campus of the Singapore universities, the energy-saving-oriented design has the highest proportion. It was concluded that only by absorbing more mature design experience and strategies can the development of green campus buildings in the Greater Bay Area go further. The findings of the paper will further provide more powerful data support for the development of the Greater Bay Area and Singapore, and simply put forward feasible and universal design patterns and strategies to a certain extent.
