How to calculate the floor coefficient of a 30-story house?

How to calculate the floor coefficient? A: Flexible use of various schemes. Before the establishment of the owners' committee, the floor coefficient was determined through consultation between the development and construction unit and the realty service enterprise, and was implemented after being reported to the municipal, district (Wujin, Xinbei District) price department and the realty department for the record. At the same time, it should be publicized to the buyers in a prominent position at the commercial housing sales site. After the establishment of the owners' committee, the elevator floor coefficient can be formulated by the owners' committee according to the principle, agreed with the property service enterprises in the property service contract with the consent of the relevant elevator owners, and reported to the municipal and district price departments and property departments for the record. Owners do these things, of course, no professional company has experience. How to make the floor coefficient? Liu Hongchang, director of the Housing Price Department of the Municipal Price Bureau, gave some reference schemes. For example, take a 20-story house as an example, the elevator goes straight to the basement, and the beneficial owner of the elevator should start from 1 floor. The middle layer is 10, 1 1, and the coefficient can be determined as 1, that is, it is paid to 0.4 yuan per square meter every month. After these decisions, there are two options to choose from. One scheme is one coefficient per layer. For example, taking 0.05 as the coefficient step, the coefficient of 9 layers is 0.95, the coefficient of 8 layers is 0.9, the coefficient of 7 layers is 0.85... 1 layer is 0.55; Backward, the coefficient of 12 layer is 1.05, the coefficient of 1. 1 4 layer is 1. 15. Another scheme is multi-layer one coefficient. For example, take 0.2 as the coefficient step, and 4 layers are a group. If the coefficient of 9- 12 layer is 1, then 13- 16 layer is 1.2 and 17-20 layer is1.4; Backward, the 5th-8th floor is 0.8, and1-4th floor is 0.6. The principle is mainly the above two, "algebraic sum is zero" and the upper and lower limits of the coefficient. Then calculate the following formula: monthly elevator operation and maintenance fee = building area ×0.40 yuan × floor coefficient.
