Air Infiltration
Air infiltration is a common phenomenon in buildings. It refers to the passage of air through cracks or gaps in building materials, allowing air to enter the building unintentionally.
One of the main consequences of air infiltration is the introduction of air pollutants into the building. These pollutants can come from a variety of sources, including exhaust gases from vehicles, building materials, and other sources. This can have a negative impact on indoor air quality, leading to health problems for building occupants.
To address this issue, it is necessary to identify and seal any gaps or cracks in the building materials that allow air infiltration. This can be done using appropriate sealing materials, such as caulk or weatherstripping. Regular maintenance and inspection of building seals should also be carried out to ensure they remain effective.
In addition to sealing gaps, it may be necessary to implement air filtration systems in buildings to remove air pollutants before they enter the building. These systems can be effective in removing particulate matter, gases, and odors from the air.
Overall, air infiltration is a common problem in buildings that can have a negative impact on indoor air quality. However, it can be addressed through appropriate sealing measures and air filtration systems. By taking these steps, building occupants can enjoy healthier indoor environments.

Air Infiltration
Air Infiltration is a process where air or other gases penetrate through small openings or gaps in building envelopes. This process can lead to energy loss and increase the risk of airborne diseases or allergens entering the building. Therefore, it is important to prevent air infiltration in buildings to ensure energy efficiency and reduce the risk of health problems.
To prevent air infiltration, building envelopes should be sealed tightly. This can be achieved by using weather-resistant materials, such as paints, sealants and weather-resistant membranes, to fill any gaps or cracks in the building envelope. Additionally, ensuring that doors and windows are properly sealed can also help prevent air infiltration.
However, air infiltration cannot always be completely prevented. In some cases, air may penetrate through small openings or gaps that cannot be completely sealed. In these cases, it is important to take measures to minimize the impact of air infiltration on the building. This can be achieved by ensuring that the building has sufficient insulation to reduce energy loss and by using air filtration systems to remove airborne pollutants.
In conclusion, air infiltration is a common problem in buildings that can lead to energy loss and health risks. By sealing building envelopes tightly and using appropriate measures to minimize its impact, building owners can ensure energy efficiency and reduce the risk of health problems.
