Elevator room on the 30th floor, 28th floor?

The advantages of a 28-story building are broad vision, low noise, good air circulation and less dust. The 28th floor is the better floor in the high-rise, so it is recommended to choose according to personal preference. However, layer 7~ 1 1 belongs to the temporary dust retention area due to the "canyon effect", so it is not recommended to buy it. The advantage of the low floor is that it is convenient to go up and down the stairs, close to the landscape of the community (if there is a landscape in the community), high psychological safety, and the floor with high unit price is more cost-effective.

Matters needing attention in purchasing elevator room:

1, fire power supply

The stairwell, fire elevator room and its antechamber, shared antechamber and refuge floor (room) should be provided with emergency lighting and evacuation indication signs, and the battery can be used as standby power supply, and the continuous power supply time should not be less than 20 minutes; The continuous power supply time of high-rise buildings with a height exceeding 100m should not be less than 30min.

2. Density landscape

Density is the key to the quality of high-rise buildings. The lower the density, the higher the quality of life. In the case of low density, we should pay attention to the landscape, especially when choosing the top floor or higher floor, we should not only pay special attention to the landscape, but also consider the future planning of the surrounding areas. If several tall buildings are built in front of the window with good scenery now, the landscape will be blocked.

3. Elevator quality

When buying a house, we must pay attention to choosing an enterprise with reliable elevator quality, ask the property maintenance personnel how to rescue when there is a fault, and sign a letter of responsibility with the developer to stipulate how to compensate for the elevator accident. Residential floors above 12 and below 18 shall have at least two elevators, one of which must have the function of fire elevator; If the functional floor of a pure residential building is between 19 and 33, and the total number of service households is between 150 and 270, there should be no less than 3 elevators, one of which must have the function of a fire elevator.

4. Property management

Whether there is a guard room on duty at the bottom of the building, whether the monitoring security measures are in place, whether there is security patrol in the building, and evacuation safety in case of emergency can not be ignored.
