In today's world, it is important to stay active all the time and have a good mood. After all, mood determines the general tone of a person's life. It depends on those influences that affect the personal aspects of the subject, his basic values. The reason for a particular mood is not always realized, but it is always there. Lingering bad moods can lead to depression, which acts negatively on the person. The street is one of the main places where a person is during the day, so elements of the subject-object environment, in one way or another, have their effect on the person. It can be sculpture, graffiti, advertising, buildings, and many other elements. But to influence emotions is easiest with the help of art objects. In this paper we will identify and justify the minimum socio-cultural requirements for art objects, which will increase the emotional background of the city. Socio-cultural requirements we will consider such requirements that adhere to the principle of humanization, require compliance with social norms and values and form an environment for a cultural dialogue between man and public space.
