What aspects does the intelligent Grade A office building include?

Grade A office building is a kind of office building, which is generally the best grade office building. Grade A is the top level of office space, and the added value is called smart office. The connotation of Grade A office building includes the following elements: perfect central air conditioning, elevators and elevator services with sufficient quantity and reasonable distribution. Even more reluctant to use 5A as a measure of the quality level of an office building. 5A office building does not represent the quality grade of the office building, but "5A" only indicates the intelligence degree of the office building, which has certain influence on the quality of the office building. However, it can never be said that the "5A" office building is a Grade A office building or the best quality office building, because there are many factors that affect the quality of office buildings, such as location, transportation, supporting facilities, parking spaces and elevators, and the degree of intelligence is only one of them.

So, what is 5A intelligence? "5A" refers to OA (Office Intelligence), BA (Building Automation), CA (Communication Transmission Intelligence), FA (Fire Intelligence) and SA (Security Intelligence). There was a saying about 3A-class office buildings before, that is, OA (Office Intelligence), BA (Building Automation), CA (Communication and Transmission Intelligence), FA (Fire Intelligence) and SA (Security Intelligence) were included in BA (Building Automation).
