Building solar potential rose diagram drawing method

Abstract

The invention relates to a building solar energy potential rose diagram drawing method, and the method starts from a building monomer, and uses a certain building to obtain the sum of solar radiationin a certain orientation within a specified time period to represent the solar energy potential of the building in the orientation. The potential of solar energy has vector characteristics, i.e., directions and sizes. Therefore, the building solar potential rose diagram is drawn by integrating the building orientation and the corresponding solar radiation quantity. The rose diagram can visually express the relation between the orientation of the single building and the obtained solar energy under specific conditions, the solar energy potential of the building can be conveniently evaluated fromthe orientation angle, and the optimal orientation of the building can be determined in an assisted mode in the design stage. In addition, the problem that in traditional building orientation designsimulation, only the optimal orientation is given or only the optimal range is pointed out, and other result expression modes are single can be solved.

Description

technical field

[0001] The invention belongs to the field of building solar energy potential evaluation and relates to a method for drawing a building solar energy potential rose diagram. Background technique

[0002] The traditional evaluation of solar energy potential is mainly from a macro perspective, and the object of evaluation is usually a certain region or city. For example, in China’s solar energy resource distribution map, it is divided into five categories. The smallest area includes most of Sichuan’s regional level Guizhou, and the largest The subdivision involves 11 provinces. This kind of macro assessment is difficult to assess the impact of the surrounding environment on solar radiation in a small area, and the surrounding shelters in a small area, such as buildings and mountains, have a great impact on the solar energy utilization of buildings. In addition, the choice of different shapes of the building itself will also have an impact on solar energy utiliza...
