The urban landscape lighting at night in China's rapid development, and the building as an important constituent element of the city, has also become the main carrier and an important part of the urban landscape at night image. The process of making buildings landscape lighting design, which is often due to lack of lighting options, lighting the way as well as the understanding of the characteristics of building surface materials and produce such bright and subjective estimate, the problem of high energy consumption in lighting design process needs to lighting design standards as a guide. Due to the lack of relevant experience, many of the city during the lighting design, almost all foreign lighting standards as a guide, but due to different objective conditions abroad, directly followed standard is inappropriate in many cases, therefore, the domestic several municipalities were introduced to the local night lighting standards is important, which is the recommended standard value, which play a key role in the lighting design which important parameters. This issue through existing domestic and international lighting standards and related information found abroad, most of the standard-setting time earlier, using illumination as the recommended value of the majority, this is intuitive and easy because the illumination in the actual lighting calculations , but many lighting pundits have repeatedly raised illuminance easy to use, but it is not intuitive to reflect the feelings of the people, so there is a great deal of inaccuracy. This is because the lighting design, we can not do without the person's subjective evaluation, brightness is the key factor. Because the the brightness calculation process is very complex, and thus only raised in many of the standard can be diffuse reflectance formula Approximate conversion, while not directly luminance as a recommended standard. The domestic local standards have been introduced in brightness as the recommended values, but more or diffuse reflectance formula translated, the recommended brightness values ​​are not uniform, and not conducive to practical application, therefore, to develop uniform national standards have been become a very important and urgent issue here, the Ministry of Construction started in 2005 a project to develop national standards for night lighting. The topic is \Early in this topic, scholars have established experimental theories and propose research directions, and the subject is on the basis of preliminary studies for the main purpose of the development of standards, were targeted for further study. Brightness is closely related to their subjective feelings, this study uses the methods of psychology, statistics, and computer technology, a large number of field surveys by a representative of the city on the domestic the buildings landscape lighting status, the surfaces of buildings The relationship between the objective parameters such as brightness, background brightness subjective feelings, to establish a theoretical model of the relationship between the three, to subjective feelings of the introduction to the determination of the standard value. The subject access at home and abroad, most urban landscape lighting recommended standards, understand the type of building decorative materials standards recommended by the study after classified as study the reflective properties of the building on the basis of these materials, through repeated testing of each material to obtain large amounts of data through the data to determine
