What level of lighting can be bright enough? It is indeed difficult to abstractly summarize the criteria for evaluating the environmental quality of night space from the numerous relational factors. Judgment depends on the value orientation. The night landscape planning and design covers two major aspects of art and technology, which correspond to qualitative (unmeasurable) standards and quantitative (measurable) standards.
1. Qualitative standards. We may as well refer to the evaluation criteria of urban design to evaluate the environmental quality of night space from the following aspects, but we focus more on the applicability of the night space environment in the evaluation of the content of the project.
Accessibility and recognizability: People's visual discrimination is significantly reduced at night. Urban lighting and lighting night landscape planning and design should consider that the night space area must have obvious characteristics, and the night space environment has a clear structure of points, lines and surfaces to enhance the recognizability of the night space.
Harmony: Emphasizes visual and aesthetic feelings. For the overall planning of the city's night skyline, a coordinated relationship is established based on the location of the night space environment, the nature of the building, density, color, material, volume, and the human activities in the night space environment.
Livability: This is the hidden goal behind all urban design evaluation standards, emphasizing the night space environment's ability to suit the public's night behavior, and considering the public's psychological feelings (comfort, safety) and visual pleasure of the night space environment sense.
Vision: Emphasize the reshaping of the elements in the night landscape of urban lighting and lighting, or strengthen the night characteristics of the urban landscape, or weaken the visual impact of the unsatisfactory landscape elements in the daytime landscape, and use light to brighten the lighting technology To improve.
2. Quantitative standards. The quantitative evaluation of technical orientation tends to regard the evaluation criteria of urban lighting and night landscape planning and design as function and efficiency. The criteria can include the following aspects:
Illumination: Urban lighting needs to meet the safety and visual comfort of urban road traffic and residents' walking. Use this indicator as a quantitative standard to measure whether the planning and design meets the needs.
Glare Index: Overly eye-catching advertising signs, neon red lights, etc. are likely to cause traffic accidents and damage the pleasantness of the city’s vision. Use this index as a standard for rectifying and managing the phenomenon of abuse of light in the night space environment.
Lighting efficiency: It can be understood as the illuminance per unit of lighting power consumption, as a standard for evaluating the urban night landscape lighting technology and equipment.
Lighting energy consumption rate: It can be understood as the ratio of lighting electricity consumption to total electricity consumption, as a reference indicator for the government and society to control lighting energy consumption, and to provide policy guidance and restrictions on the overall planning of night landscapes from a macro perspective.
