The commercialization of architecture has led to dramatic changes in the design of commercial building exteriors, with a variety of design techniques emerging. Through the efforts of architects to innovate, new design techniques are gradually coming to maturity, and a lot of new architectural vocabulary has been generated. Therefore, if we can carefully study, analyze and summarize the exterior design techniques of today's commercial buildings and skillfully use these creative new languages, we can create more contemporary commercial buildings and urban environments for our society, and better satisfy the needs of people's material and spiritual life. There are many different ways to design the exterior of commercial buildings, and the following are some typical aspects and examples to be analyzed and discussed. The use of history adopts the architectural shapes and details that have appeared in history, which are refined and abstracted, and applied to the exterior design of commercial buildings, which can arouse people's memories of the past. Historical symbols are often used in restaurant and inn buildings, such as Las Vegas City in the United States, Beijing Teahouse, Shaoxing Xianheng Hotel and so on. And people's nostalgia in turn stimulates the use of historical buildings. The concept of individuality using the city's large commercial building shape is the most important thing is to highlight the personality of the commercial building, there is a prominent commercial atmosphere. Within the scope of conditions allow, as far as possible through the proportion of the building, color, material use, to create a new and beautiful image to attract customers. The design of personality is not fixed, the following analysis of some examples for reference. High-tech use of this approach to the extreme use of contemporary high-tech achievements, the use of sculpture and exaggerated forms, light technology, silver aesthetics and other methods, abandon the inside-out approach and function as a single expression of the content of the dogma, the development of structural forms, construction equipment, process technology, material texture and other content of the new approach. High-strength aluminum, mirror glass, and expensive industrial materials have become the signboards for businessmen to show off their wealth and strength. High-tech like to use the latest materials, especially hard aluminum or alloy materials, in order to exaggerate the exposed approach to shaping the image of the product, often some of the original internal components, machinery exposed. Sometimes the complex parts are painted with bright colors, both the taste of the performance and the meaning of identification. Rich in modern beauty and machine beauty. Hong Kong's HSBC is a typical example. The use of cartoon cartoon techniques cartoon is a product of modern film and television, in people's impression is bright, lively, relaxed image, by the public's favorite. At the same time, cartoon bright colors, cute and humorous modeling in the visual arts is unique. Like this for the public to appreciate and love the art form naturally by architects and owners introduced into the commercial building design, because to attract the public and their favorite is to trigger the prerequisites for consumption. Disneyland in the United States is a typical example of this. The use of building appearance changes with the accelerated pace of life, urban cultural life has appeared the trend of popularization, a product life cycle has been greatly shortened, with the changes in the business cycle and changes. Commercial buildings are certainly no exception; they must conform to fashion and follow the changes in popular trends. However, due to the limitations of the specificity of the building itself, a large number of facade renovation came into being. The means of renovation work is small, flexible changes, design freedom, and more importantly, can be completely changed in a short period of time, giving people a refreshing feeling, renewed vitality. In this sense, this is a commercial packaging effect. The use of classical aesthetics in opposition to the traditional view of aesthetics perspective seeks harmony, unity, and perfection of the aesthetic mood, and realizes this purpose by strictly following the laws of formal beauty. In contemporary commercial architectural design, out of the purpose of individuality and play in the commercial society, the tendency to pursue non-perfection and non-harmony has emerged in commercial architecture. This tendency is mainly reflected in the appearance of the building, showing the characteristics of dilapidated, grotesque and disorderly, and completely subverting the traditional aesthetic concepts and hierarchy. For example, American architect Gehry focuses on flawed and unfinished beauty, and his work is to split and burst the building so that it fizzles out in every direction. The group unabashedly rebelled against classic modernism with a series of their designs. stores that invariably reveal a ruptured, mutilated, collapsed body. This expansion of the aesthetic categories of grotesque, defeat, and disorder, which are antithetical to the concept of perfection, reflects a shift in contemporary aesthetic sensibilities, in addition to being related to the values of commodity advertising in the commercial world
