Air permeability and Load Reduction
Air permeability is an important aspect of any structure. It is an important factor in determining the structural strength, resistance to weathering, and comfort provided by the structure. Air permeability refers to the ability of air molecule size particles to pass through a material and transform from one phase to another, thereby allowing for a more comfortable atmosphere for those occupying the space.
Air permeability is especially important for structures that are exposed to changing temperatures and weather patterns. Without an adequate level of air permeability, excessive heat loss or gain can occur due to fluctuations in atmospheric temperature and/or moisture. Air permeability helps to maintain constant temperatures and an equal level of comfort throughout the structure.
Air permeability also contributes to the overall safety of a structure by reducing the amount of load exerted on the structure itself. By allowing air molecules to move through the material, the weight of the structure is reduced. This not only reduces the risk of physical damage to the structure, but can also reduce the amount of maintenance needed to keep the structure sound and secure. Additionally, air permeability helps to reduce the energy loss associated with heating and cooling the structure, resulting in more efficient energy usage.
Air permeability also plays an important role in the longevity of a structure’s life. Air permeability can help to reduce the effects of corrosion by allowing moisture in the form of water vapor to evaporate away from the structure. This can help to prevent the damaging effects of oxidation, rusting and other forms of deterioration.
Finally, air permeability can help to reduce air pollution levels inside the structure. By allowing air particles to enter and exit the structure, pollutants such as smoke and particles of dust can be filtered out, resulting in healthier air quality. In addition, air permeability can reduce the level of harmful chemicals in the air by allowing them to be pulled away from the structure.
As can be seen, the importance of air permeability cannot be understated. Not only does it improve the overall safety and comfort of a structure, but it also contributes to its durability and cleanliness. By allowing air to pass freely between the interior and exterior of a building, air permeability drastically reduces the amount of load exerted on the structure and helps to promote a healthier atmosphere. Taking all of these benefits into consideration, it is easy to see why air permeability is an essential part of any structure.
