BRIDGING THE DEVELOPMENT GAP OF GREEN BUILDING IN SOUTHEAST ASIA: COMPARISON BETWEEN SINGAPORE AND VIETNAM

ABSTRACT In recent years, the green building industry in Southeast Asia has shown a clear trend of development. However, the development differences among Southeast Asian countries are generally large, and existing studies lack a comprehensive comparative analysis of green buildings in developed and developing countries in the region. This study takes Singapore and Vietnam as typical representatives of developed and developing Southeast Asian countries and compares their green building rating systems, green building technologies, and the current status of building energy consumption of various types of commercial buildings. The results show that there is a significant difference in the overall energy consumption levels between Singapore and Vietnam. The overall energy consumption level of buildings in Singapore is much higher. And probably due to the standardization of the green building rating system and advanced development of green building technologies in Singapore, the energy consumption level of all types of commercial buildings in Singapore is more stable and less fluctuating than in Vietnam. The results of the study critically point out differences in green building development and the current status of energy consumption between developed and developing countries in Southeast Asia and provide a direction for improving the existing green building evaluation standards, promote the development of green buildings in developing countries, and to narrow the regional gap.
