Problems solved by technology

ESRI has launched the solar radiation calculation module (Solar Radiation) since ArcGIS 10.5 version, but it only considers the influence of terrain factors, does not consider the influence of surrounding buildings, and ignores the solar energy utilization potential of building side facades

Embodiment 1

[0054] figure 1 It is a flow chart of the method for assessing available solar energy resources of urban building groups involved in the present invention.

[0055] like figure 1 As shown, the present embodiment 1 provides a method for assessing solar energy resources available for urban buildings, including: obtaining sun position information; obtaining geometric and orientation information of buildings; obtaining roof and side elevation data of buildings; and according to Sun position information, relative position between buildings, geometric relationship information, building roof and side facade data, calculate the shaded time of different positions of building roof and side facade, in order to obtain building roof and side facade reception The total solar radiation of the total solar radiation and the global total solar radiation within the preset time period; under the premise of considering the shading effect of surrounding buildings and environmental factors, the sol...

Embodiment 2

[0085] Image 6 It is a functional block diagram of the solar energy resource evaluation system available for urban building groups involved in the present invention.

[0086] Such as Image 6 As shown, on the basis of Embodiment 1, the present Embodiment 2 also provides a system for evaluating solar energy resources available for urban buildings, including: a sun position acquisition module, which acquires sun position information; a building information acquisition module, which acquires building information The geometric and orientation information of the building; the building data acquisition module obtains the roof and side elevation data of the building; and the radiation calculation module, based on the sun position information, the relative position between buildings, the geometric relationship information, the roof of the building and The side elevation data calculates the shading time of different positions of the building roof and side elevation to obtain the tota...

Abstract

The invention belongs to the technical field of solar energy resource evaluation, and particularly relates to an urban building group available solar energy resource evaluation method and system, andthe method comprises the steps: obtaining the position information of the sun; obtaining geometric and azimuth information of the building; acquiring roof and side facade data of the building; and according to the sun position information, the relative position between the buildings, the geometrical relationship information and the roof and side elevation data of the buildings, calculating the height of the buildings, and calculating the sheltered time of different positions of the building roof and the side vertical surface; the total solar radiation received by the building roof and the sidefacades and the total global solar radiation in the preset time period are obtained; the solar energy utilization potentials of the roof and the side facades of the building group are accurately evaluated, support is provided for establishing informatization management systems for evaluating, inquiring, adjusting and the like of solar energy resources of the building group in an urban target area, and therefore scientific decision support is provided for development and utilization of the solar energy resources of the urban building group.

Description

technical field [0001] The invention belongs to the technical field of solar energy resource assessment, and in particular relates to a method and system for assessing available solar energy resources of urban building groups. Background technique [0002] With the process of global urbanization, cities consume about 2 / 3 of the world's primary energy, resulting in about 71% of the world's greenhouse gas emissions directly related to energy. Among them, building energy consumption accounts for more than 1 / 3 of the world's terminal energy consumption and more than 1 / 2 of electric energy consumption. With the global emphasis on energy conservation and emission reduction, low-carbon ecological cities have become the development direction of future cities. As buildings are an important part of cities, how to promote the development of urban buildings in a green and sustainable direction is an urgent problem to be solved. Developing the utilization potential of renewable energy ...
