Abstract

The invention provides a method and device for dynamically generating sunshade behaviors based on building energy consumption simulation software. The method comprises the following steps of acquiringa calculation result from building energy consumption simulation software, judging whether a person exists or not, calculating to obtain a pull-up behavior probability, a pull-down behavior probability and a no-behavior probability by utilizing a first sun-shading behavior prediction model when the person exists, and determining a sun-shading behavior through a random sampling method; judging whether a behavior exists or not, if not, judging whether the behavior is a pull-up behavior or not, calculating the pull-up behavior through a second sun-shading behavior prediction model to obtain a pull-up amplitude probability, determining a pull-up amplitude through a random sampling method, and taking the pull-up amplitude as a current sun-shading position; and calculating the pull-down behavior by using a third sun-shading behavior prediction model to obtain a pull-down amplitude probability, and determining a pull-down amplitude by using a random sampling method to serve as a current sun-shading position; and finally, inputting the current sun-shading position into building energy consumption simulation software.

AI Technical Summary

Problems solved by technology

[0010] In summary, the shading behavior modules in the existing building energy simulation software are only a setting of the shading state, not a description of the shading behavior, and it is impossible to simulate the changes in the surrounding environment based on the characteristics of the shading behavior to promote the typical shading behavior. The dynamic generation of behavior is just a way to define the shading state with a schedule or manually input the threshold of each parameter, rather than a description of shading behavior

Therefore, it is impossible to simulate the energy consumption simulation results with a small difference from the real value, which will also cause a large deviation in the estimation of the energy demand of the building in actual application, and the goal of minimizing energy consumption cannot be achieved.
