Nowadays, equipped with the more advanced BIM technologies, the whole construction industry should be more purposefulness in project management, adopting a reasonable technological path to achieve the clearly defined technical goals. Aiming at the informatized management on green construction in projects, and from the perspective of project management, this paper develops a BIM-based informatized green construction management platform integrating the new technologies of BIM, IoT, and etc., to meet the needs of green construction evaluation. The paper sorts out the overall functional framework of the platform and the specific functional modules. Through the application of the platform, a project is able to implement detailed and targeted green construction management according to the initial objectives of green construction established by the project, and to evaluate the achievements of green construction management, which will surely improve the overall level of green construction management.
