Abstract

The invention provides a method based on local light climate for simulating natural lighting performance of a building in a severe cold region. The method comprises the following steps of 1, establishing a local sky brightness distribution database in the severe cold region; 2, constructing a mapping relationship of sky element brightness data and an artificial sky lamp set; 3, conducting numerical control establishment of a physical model of a simulation building; 4, simulating the natural lighting performance of the building on the basis of the local light climate. According to the method, amicroscopic model can achieve accurate restoration of building spaces with standard forms and non-standard forms and optical property information of building materials, and meanwhile the high-precision simulation of the natural lighting performance is achieved by adopting real light climate data.

Description

Technical field [0001] The invention belongs to the technical field of building natural lighting performance simulation, and particularly relates to a method for building natural lighting performance simulation in severe cold areas based on local light climate. Background technique [0002] In the context of sustainable development, making full use of natural lighting in buildings is of great significance to reducing building energy consumption, and natural lighting can effectively improve the quality of building light environment. The evaluation of natural lighting performance relies on three methods: theoretical calculation, software simulation and physical model simulation, especially software simulation and physical model simulation are the most widely used. [0003] Among the computer software simulation methods, the radiance core algorithm engine is currently the most widely used. However, the CIE standard sky and perez sky generated by the two sky generation program modules ...
