Explanation of architectural terms: 1. Transportation hub II. Daylighting coefficient 3. city texture

Dividing cities with the most basic elements (such as quadrangles in Beijing) is infinitely divided into the quality of basic elements, and the form of urban division is the texture of cities. The texture of the city can reflect the spirit of the city, and the most profound thing in the city is the texture of the city.

The daylighting coefficient is the ratio of the illuminance generated by the diffuse light of a fully cloudy sky at a given indoor level to the illuminance generated by the diffuse light of a fully cloudy sky at the same time on an open outdoor level.

Transportation hub: in public buildings, considering the distribution of people, the change of direction and the connection of horizontal and vertical transportation spaces, it is necessary to set up halls, halls and other spaces to play the role of transportation hub and space transition. Attention should be paid to the coordination with the pedestrian flow route in the design, and the size should be coordinated with the nature, scale and quality standard of the building.
