Fresh air enters an air conditioning system through the intake vents. These vents are typically located on the exterior of the building and allow outside air to be drawn into the system. Once inside, the fresh air is filtered and then distributed throughout the building via the ductwork. This process helps to improve indoor air quality and can also help to regulate the temperature and humidity levels within the building. **

A fresh air ventilation system in masonry works by bringing in outside air and distributing it throughout the building. This is typically achieved through the use of air ducts and vents that are integrated into the masonry structure. The system may also include filters to remove pollutants and allergens from the incoming air. By continuously bringing in fresh air and removing stale air, the ventilation system helps to maintain good indoor air quality and regulate the temperature and humidity levels within the building. **

A local transport system needs to be available from a size where the population density and demand for transportation services justify the need for a structured system. Typically, this would be in urban or suburban areas with a significant population that requires efficient and reliable transportation options. The size can vary depending on factors such as population size, geographic layout, and transportation needs of the community. It is important for local authorities to assess these factors to determine the appropriate size for implementing a local transport system. **
