Answer :
Final answer:
Factors reducing the effectiveness of vertical ventilation include poor drainage, crowded housing, high humidity levels, exposure to pollutants and inadequate expulsion of indoor air.
Explanation:
Common factors that can reduce the effectiveness of vertical ventilation include improper water resource management, which can cause poor drainage, leading to increased humidity and reduced air exchange rates. Crowded housing may also impede air flow, while high temperature and humidity levels can escalate the concentration of indoor pollutants. Additional factors such as exposure to gases or fumes, secondhand smoke, pollution, and the use of cooking fires without proper ventilation further deteriorate the air quality by decreasing the rate of ventilation, which is crucial for diluting and removing pollutants from indoor spaces.
Some of the common factors that can reduce the effectiveness of vertical ventilation are improper water resource management, crowded housing with poor ventilation, exposure to certain gases or fumes in the workplace, frequent use of a cooking fire without proper ventilation, and obstruction of ventilation.
