The internal function of the activity center for the elderly is centered on the entertainment and rest of the elderly, supplemented by learning, catering, medical care and management, and distinguishes between the inside and outside, the movement and the turbidity. They are either connected or separated, which constitutes the architectural environment of the elderly activity center. Space creation place is basically composed of dynamic area and static area. The dynamic area includes table tennis room, billiards room, chess room, mahjong room and chat room. The static area includes library, calligraphy room, etc. The elderly can choose their own venues according to their hobbies, which can not only exercise, but also broaden their horizons and provide a good spiritual place for the elderly in their later years.

(1) functional components. The behavior in public entertainment space changes with the change of people's lifestyle, and its content is rich, such as physical exercise, cultural entertainment, reading, poetry appreciation, painting, calligraphy, singing, dancing, handcrafting and so on. According to the behavior analysis, we should provide public entertainment space for the elderly to meet various interests: handicraft room, calligraphy room, appreciation room, lecture room, painting room, pottery room, gardening room and so on. , and set the corresponding storage space in these spaces. Compared with family pension (home pension), social pension facilities can provide conditions for the elderly to learn from each other, not only to meet their various interests and hobbies, but also to set up a display space for them to display their achievements, encourage the elderly to actively participate in social affairs within their power, and provide a working platform for those elderly with artistic accomplishment to pursue freedom and exert their residual heat.

(2) Entertainment space environment. Based on the behavior needs of the elderly, according to the nature of behavior, behaviors with the same activity characteristics can be carried out in the same room, while behaviors with different behavior characteristics should be carried out separately as far as possible. Many people need to be refreshed in a quiet environment or have intimate conversations with relatives and friends. People who read books and newspapers want quiet space and bright lights, while old people who watch TV don't want their strong interest to be disturbed by the sound of mahjong. Different behaviors have different requirements for space, and carrying out multiple activities in the same space requires certain activity consistency. Increase the level of space, set up a semi-private area in public entertainment space, and the old people can enjoy themselves without interference.

(3) the scale of entertainment space. Generally speaking, the closer people are, the closer they stand. Friends stand closer than strangers, and people who want to be friends stand closer. Although most people seldom think about personal space, standing closer is usually a sign of friendship or interest. Ear energy is an important tool for people to receive information invisible to eyes and eyes, and it is also an important tool for social communication. However, the hearing loss of the elderly often shows that the elderly tend to be close to the speaker to make up for the hearing loss, which greatly affects their special preference for the scale and form of communication space, and they prefer smaller and closed communication space. Personal space affects the size of public space. The size of public space in old buildings is in direct proportion to the number of users, and the size of space is determined according to the number, use mode and frequency of old people and the number of residents in surrounding communities.

Calculate the approximate area of each space according to the total area.
