The renewable energy system is an important part of ultra-low energy consumption building. Using renewable energy for building heating and cooling can reduce the use of primary energy and reduce environmental pollution. The paper firstly introduces the development history and current situation of ultra-low energy buildings at home and abroad. Secondly,according to the existing engineering cases of ultra-low energy consumption buildings,the technical characteristics of renewable energy system which is based on solar energy are described and analyzed, and then the corresponding economy and practicability of the system are discussed. Afterwards,some renewable energy systems used in the project cases are compared, and the different types of renewable energy systems that are widely used are summarized. The research content of the paper is conducive to promoting the promotion and application of renewable energy technology for ultra-low energy consumption buildings,providing a reference for actual engineering projects, realizing the benefits of energy conservation and environmental protection, and facilitating the implementation of carbon peak and carbon neutrality.
