Method for estimating solar radiation of surface buildings based on BIM

Abstract

The invention provides a method for estimating solar radiation of surface buildings based on BIM, which comprises the following steps: 1) constructing and optimizing a multi-scale fine surface model;2) carrying out spatial planning and expression of urban architectural information based on BIM; 3) carrying out BIM-based natural lighting evaluation of urban buildings; 4) establishing the simulation and prediction model of solar radiation space curved surface; 5) carrying out BIM-based quantitative evaluation of solar radiation spatial and temporal distribution; 6) building a skin response design strategy based on BIM. The advantages are: 1) the method of digital surface model zoning, sub-scale construction and optimization based on high-score remote sensing images is proposed; 2) the method solves the problem of quantitative estimation of solar radiation in the existing buildings and planned buildings in the built-up area; 3) scientific guidance is provided to the simulation of urban micro-scale eco-environment elements; 4) theoretical basis and technical support are provided for the utilization and development of solar radiation energy in urban areas; 5) expansion of the theoretical basis and technical methods of multi-disciplinary fusion of urban micro-scale eco-environment is realized.

Description

technical field [0001] The invention is a method for estimating solar radiation of surface buildings based on BIM, and belongs to the technical field of environmental monitoring and protection. Background technique [0002] With the advancement of the strategic process of new-type urbanization, the issue of temporal-spatial coupling between urbanization and the ecological environment has drawn increasing attention and attention from all walks of life. There is an extremely complex interaction, interaction coupling and interdependence between urbanization and the ecological environment. From the perspective of the coercive effect of urbanization on the ecological environment, the concentration of urban population, the expansion of urban space, the increase in economic scale, and the rapid rise of the social economy all have impacts and pressures on the ecological environment, resulting in the decline of ecological service functions; The improvement of the third geographical ...
