Abstract:

Green building has become an inevitable trend due to the implementation of the Evaluation Standard for Green Building (ESFGB) in China. Because of its geographic location in the central-south region of China, Hunan developed relatively late compared to other more industrialized regions of China. However, with the local government’s attention and focus, Hunan made enormous progress and caught up rapidly. Green residential building grows even faster than green public building. The overall floorage of residential building is about two times than that of public building among these Green Building Labelling (GBL) schemes in the past five years. In this paper, 34 GBL residential building schemes of Hunan Province were analyzed through data analytics including quantity and floorage, star level proportion and geographical distribution to reveal the developing status of green residential building. Meanwhile, technologies used in these schemes were divided into five categories including Land Saving, Energy Saving, Water Saving, Material Saving and Indoor Environment in accordance with Evaluation Standard for Green Building in Hunan Province (ESFGBHP). Then the technology using frequency of GBL residential schemes were counted and sorted by different category and star level. Combined with specific technology cost, the relationship between frequently-used technologies and incremental cost of different category and star level were discussed.
