1. Electricity charges for public lighting, including lighting in the corridor and night lighting in the park.

2. The outline lamp electricity fee of the building facing the street.

3. Power consumption of equipment during maintenance in public areas.

4. Energy cost of greening sketches in the park (such as fountains and water landscapes).

5. Water and electricity charges for greening in the park.

According to the Code for Property Survey, the shared public building area is:

1. Lobby, public hall, corridor, aisle, elevator (building) lobby, stairwell, elevator shaft, elevator machine room, garbage chute, pipe shaft, water pump room, fire escape, transformer (distribution) room and guard on duty.

2. The partition walls and external walls (including gables) between each set and the public building space are half of the projected area of the wall area.

The public building spaces that should not be included are:

1. Warehouse, motor vehicle garage, non-motor vehicle garage, driveway, etc., which are used as the basement of civil air defense projects and independent use spaces with independent functions;

2. Houses that are self-operated and occupied by the selling unit;

3. Guard room and management (including property management) rooms serving multiple houses.

the * * * construction area to be apportioned is the construction area of the whole building minus the sum of the construction areas in all sets of the whole building, and minus the construction areas after the basements, carports, garages for independent use, guard rooms, management rooms serving multiple buildings, and civil air defense works.

pool calculation

1. For a multi-storey commercial residential building, the allocation coefficient of the whole building and the * * * built-up area must be calculated first, and then allocated according to the proportion of each set of built-up area in the building.

2. For the multi-functional complex building, the * * * shared building area coefficient of the whole building and different functional areas in the building must be calculated first, and then shared according to the proportion of the building area in each functional area in the building.

*** If there is any change in the contents of the calculation of the apportioned construction area, it shall be subject to the provisions of the current relevant documents of the Ministry of Construction.

Generally speaking, the shared area is the common area of the whole building. Of course, the walls of the building are also inside, and the house with elevator is relatively large.

calculation method for sharing public building area among households: the basic idea is to share it in proportion with the interior area of each household:

(1) Step 1: Calculate the sharing coefficient

Sharing coefficient = sum of public area to be shared/sum of interior building area of each suite = (sum of total building area and interior building area of each suite)/sum of interior building area of each household.

(2) Step 2: Common shared area of each suite = shared coefficient × interior construction area of each suite.
