4楼、8楼、14楼、18楼不能买？错了！内行人：这3楼层真正不建议购买

Core Viewpoint - The article explores the common beliefs regarding certain floors in residential buildings, particularly the superstitions surrounding floors like 4, 8, 14, and 18, and provides data-driven insights into which floors are advisable to avoid based on objective issues rather than myths [1][12]. Group 1: Floors to Avoid - The first category to be cautious about is the ground floor (1-2 floors), which has a lower satisfaction rate among residents due to issues like humidity, pest problems, and security risks. Ground floor residents report an average satisfaction rate 18.7% lower than other floors [3][4]. - The second category is the top floor, which faces challenges such as temperature extremes, leakage risks, and noise disturbances from equipment. Top floor residents experience an average temperature difference of 3-5°C higher in summer and 2-4°C lower in winter compared to middle floors [5][6]. - The third category includes elevator boundary floors, which often face inconveniences like longer waiting times for elevators and difficulties for visitors and delivery personnel due to elevator zoning. Residents on these floors experience a 40% longer average waiting time for elevators [7][8]. Group 2: Ideal Floor Choices - Floors 3-7 (excluding the 4th floor) and middle floors (between 1/3 and 2/3 of total floors) are generally preferred by buyers. These floors avoid the issues of ground floors and are not too high, providing a balance of light, ventilation, and safety [8][10]. - Middle floors, particularly in a 30-story building, offer minimal temperature fluctuations and lower noise levels, making them ideal for living conditions. The average temperature difference for middle floors is about 40% smaller than for top floors and 25% smaller than for ground floors [8][10]. Group 3: Additional Considerations - Factors such as building orientation, age, and quality significantly impact living experiences. South-north oriented buildings provide 35% more natural light compared to single-direction buildings, and newer constructions generally have better insulation and soundproofing [10][11]. - Economic considerations also play a role in floor selection. Budget-conscious buyers may find lower prices on traditionally "unlucky" floors, while those with higher budgets can opt for the best combinations of floor and orientation for long-term comfort and value [11][12].
