Green building has installed ecological facilities and energy-saving facilities on the basis of traditional buildings, and replaced building materials and building components, which undoubtedly requires an increase in construction costs. However, the analysis should not remain at the stage of design goals and theoretical expectations, but should be based on the analysis of actual operating data throughout the life of the green building.
At present, there are numerous evaluation index systems for green buildings. For example, China’s Green Building Rating Standards, the UK’s Building Environmental Assessment Method (BREEAM), the US LEED Green Building Rating System, and Canada’s Green Building Rating Tool. ” (GBTool) and Japan’s CASBEE, among others. Since green building examples in different regions and countries are not necessarily comparable, it is difficult to establish a globally consistent green building performance parameter index and certification system, and differences in assessment methods based on different technical and commercial starting points also bring about differences in assessment methods. In recent years, China has developed green building evaluation rules for hospital buildings, industrial buildings, and office buildings based on the Green Building Evaluation Standards, which are being used to refine the evaluation methods in the form of classifications and become more operational guidelines.
The realization of green and low carbon is a cyclical cycle that begins a second cycle by moving from measurement data, data visualization, evaluation of effectiveness, data analysis, design of improvement plans, and implementation of improvement plans at various stages, and then back to the measurement data. It’s an endless cycle of work during the building’s operational life. Because the building’s function will be adjusted, the load is a random process, and the equipment system has a gradual aging process, in each cycle, all kinds of conditions and problems will be found, which need to be optimized and improved to improve the performance of the building and equipment system.

“Green building is an organic and holistic concept that runs through the entire process of planning, design, construction, use and maintenance of a building, covering the entire life cycle of the building. “Green building” focuses on harmony with the surrounding environment, including the use of daylight, air circulation, landscape environment and other comprehensive considerations, to provide healthy and comfortable space for users and occupants, and the formation of a positive impact on the surrounding environment. “Green Building” is concerned with the rational use and conservation of building materials and energy, thus saving energy and materials to the greatest extent possible in every aspect of the construction and use of buildings. “Green building infiltrates environmental protection technology, energy-saving technology and information technology into all aspects of people’s lives, and uses the latest concepts and the most advanced technology to solve the problems of ecological energy saving and living comfort. In short, “green building” is part of the natural environment, and together constitute a harmonious organic system.
Green building star rating is not the goal of engineering construction, but only a means to promote energy conservation and emission reduction and protect the environment and resources. When we talk about green building technology from a scientific point of view and the scale of the continuity of the human living environment, operational data is the basis, and effective technical support requires an intelligent monitoring system.
