Abstract

The invention belongs to the technical field of environment evaluation, and discloses a comprehensive index evaluation method and system for indoor and outdoor air environment quality of a green building group. The comprehensive index evaluation system for the indoor and outdoor wind environment quality of the green building group comprises an environment partitioning module, a temperature monitoring module, a central control module, a wind speed monitoring module, a circulation rate monitoring module, an evaluation factor determination module, an environment monitoring module, an evaluation model construction module, a model training module and a comprehensive evaluation module. According to the invention, the environment quality evaluation model is constructed by determining the environment evaluation factors, and the constructed model is trained to obtain the optimized environment quality evaluation model, so that the evaluation efficiency of the environment quality is higher, and the evaluation is more accurate. According to the environment quality evaluation method, the indoor environment and the outdoor environment can be reasonably divided, the indoor environment and the outdoor environment can be evaluated respectively, and the accuracy of the evaluation result can be improved.

Description

technical field [0001] The invention belongs to the technical field of environmental evaluation, and in particular relates to a comprehensive index evaluation method and system for indoor and outdoor wind environment quality of green buildings. Background technique [0002] Green buildings are in the stage of rapid development in my country. Energy saving and improvement of indoor and outdoor environmental quality are the basic requirements of green building design, while natural ventilation plays an important role in energy saving and emission reduction, improving the comfort of the building environment and improving indoor air quality. important role. [0003] The wind environment design of green buildings needs to optimize the relationship between buildings and their bases, surrounding buildings, dominant wind direction, and building groups, rationally select building shapes and design interior spaces, and rationally organize indoor air circulation paths so that buildings ...
