An efficient automatic high light reduction carbon reduction method and system for buildings

Abstract

This invention provides an efficient automatic high-light carbon reduction method and system for buildings, relating to the field of building lighting control technology. The method includes: acquiring solar position parameters, curtain wall optical property parameters, shading optical property parameters, and indoor space geometric parameters for each lighting zone; inputting these parameters into a preset ray tracing model; simulating the propagation path and energy attenuation of light in the indoor space to analyze and obtain the distribution of natural light contribution in each lighting zone and the light field intensity values ​​at various characteristic locations within the indoor space; constructing a spatial discretization model covering each lighting zone; calculating the light field gradient and light field divergence at each characteristic location; and forming light field characteristic parameters characterizing the spatial distribution of natural light. This invention can achieve adaptive and coordinated control of natural light utilization, artificial lighting, and shading adjustment, balancing the quality of the indoor high-light environment with building carbon reduction goals.
