Revision Notes
This standard is revised by the China Academy of Building Research of our ministry and relevant units in accordance with the requirements of the State Planning Commission's Document No. [1987] 2390, and is revised from the "Industrial Enterprise Lighting Design Standard" (TJ33-79). During the revision process, the revision group conducted extensive investigations and studies, carefully summarized the experience since the implementation of the standard, absorbed new scientific research results, and widely solicited opinions from relevant units across the country. Finally, our ministry and relevant departments reviewed and finalized the draft. This standard is divided into four chapters and eight appendices. The main contents of this revision are: the daylighting coefficient value on the working surface of the production workshop, the window-to-floor area ratio, and the light climate zoning coefficient, sunny direction coefficient and glare evaluation standard are added. If any amendment or supplement is found during the implementation of this standard, please send your comments and relevant materials to the Institute of Building Physics, China Academy of Building Research (No. 19, Chegongzhuang Street, Beijing) for reference in future revisions.

Quantitative Lighting Standard
This standard shall use the lighting coefficient C as the quantitative index of lighting design. Article 2.0.1

The daylight factor of a certain point in the room can be calculated as follows: E.
×100%
Wherein, E is the illuminance of a certain point in the room (Ix); (2.0.1)
E is the outdoor illuminance (Ix) at the same time as the illuminance of a certain point in the room.Article 2 The selection of standard values ​​of daylighting factors shall comply with the following provisions: 1. The side daylighting shall take the minimum value of the daylighting factor; 2. The top daylighting shall take the average value of the daylighting factor; 3. Rooms with both side daylighting and top daylighting can be simplified into side daylighting areas and top daylighting areas, and the minimum value of the daylighting factor and the average value of the daylighting factor shall be taken respectively.
Note: The calculation points of the daylighting factor can be determined according to Appendix 2 of this standard. Article 2.0.3 The standard values ​​of daylighting factors on the working surfaces of workplaces shall comply with the provisions of Table 2.0.3.
