De-Light: a software tool for the evaluation of direct daylighting illuminances both indoors and outdoors--comparison with Superlite 2.0 and Lumen Micro 7.1.

摘要

Regarding techniques used to evaluate daylighting illuminances, recent years have been a steady increase in the use of computer programs, owing to increased speed and memory capacity. Diespite a rise in the amount of aviailable daylighting data, even the latest programs on the market only use standard CIE and IES sky models: besides, input climatic data and calculation procedures used by these programs do not always lend themsevels to esy comparison: consequently, in the presence of different results from the programs, it is not always clear which parameters are responsible for these differences.
