Relative Brightness of Facades of Parallel Buildings in Urban U-Shaped Development

The average brightness of the building facade depends on the decoration of the building, the albedo of the underlying surface adjacent to the building, the decoration and the mutual arrangement of all buildings and structures adjacent to the building in question. At the same time, opposing buildings in a complex way affect the distribution of light currents inside the room. The article considers the relative brightness of the facade for a building located parallel to the building in the development. The calculation of the relative brightness coefficient of the facade for this case is given. The calculation of the relative brightness coefficient of the facade for this case is given. The conclusion of the coefficient of relative brightness of the facade of parallel buildings in urban U-shaped urban development presented in the article is based on the consideration of three components that affect its value: KEO component on the facade of the designed building under open sky, taking into account the reflected component from the earth’s surface; KEO component on the facade of the designed building in the development from that part of the skyline that is shielded by opposing buildings; a coefficient that takes into account the increase in natural illumination on the facade of the building due to the repeated exchange of reflected flows between the facades of the buildings and the section of the earth’s surface adjacent to the buildings. Based on formulas reflecting the method of calculating the coefficient of relative brightness of the facade of parallel buildings in a U-shaped urban development, the calculation of the average relative brightness of the facade for this type of urban development was made, and a table with its values is given.
