This article introduces the public building energy consumption quota management and system construction carried out by Beijing public building energy consumption quota management information system, which may lay the foundation for electricity, heating, water supply, gas energy consumption quota management and help to better carry out related work.

This article introduces the application of building energy efficiency software in foreign countries, studies the development background, overview and technical route of the "Energy Star" project launched by the U.S. Environmental Protection Agency, and analyses the building energy efficiency comparison work carried out in China. This article suggests that China should enlarge the data base of building energy efficiency through multiple channels when developing building energy efficiency comparison tools, find basic data that are suitable for building energy efficiency comparison in China, and develop internet-based building energy efficiency comparison tools.
