Research Status of Bottom-Up Building Energy Consumption Modeling Based on Bibliometrics

Energy consumption and greenhouse gas significantly contribute to the global warming. Building-related energy consumption accounts for 40% of the world’s total energy consumption. It is necessary to use computer-aided technology such as BIM-based performance simulation to build energy consumption modeling and analyze the energy consumption of buildings in different building scales. The approach of building energy consumption modeling can be divided into top-down and bottom-up. The bottom-up approach firstly get dispersed buildings’ energy consumption data, then sum up dispersed data, and simulate the building energy consumption of required building scales (e.g., urban, national). In this paper, VOSviewer is used to perform a bibliometric analysis on the literature from Web of Science. The development prospects and obstacles of bottom-up approach are analyzed, considering the Chinese construction industry energy saving demand and technology application status in China.
