Embodiment 1

[0035] In this example, Tianjin meteorological data is used as the specific analysis background, and the initial model is selected as figure 1 As shown in dotted line 1, this initial surface is a Nurbs surface uniquely determined by 6 control points. Except for the positioning of the two endpoints, the 4 control points in the middle are used as adjustable change parameters. The names and coordinates of these 4 adjustable control points See Table 1 for the data. This example calculates the daily cumulative solar radiation from 8:00 am to 16:00 pm in June, July, and August in Tianjin in summer. The solar radiation absorption of the initial model is 30673.60kW·h.

Abstract

The invention discloses an optimization method of a curved-surface building skin, and aims to provide the optimization method which is of the curved-surface building skin and uses a genetic algorithmto carry out perfection adjustment on a preliminary model, and thus obtains a curved-surface form with an optimal solar power absorption rate. A preliminarily designed curved-surface building skin form is used as an optimization object to extract control parameters; and optimization design is carried out on the free-form curved-surface skin form according to genetic-algorithm principles to enablea thin-film photovoltaic-device to have optimal absorption quantity for solar radiation. According to the optimization method of the invention, the genetic algorithm is utilized for optimization design of the curved-surface skin, the solar power radiation absorption quantity of the curved-surface thin-film photovoltaic-device mounted on the curved-surface building skin is maximized, and efficiencyof utilizing solar power by a building is improved.
