Final answer:
Air infiltration refers to the process of outside air leaking into a house, which is managed by weather stripping and sealing. Too tight of a house can be harmful because fresh air is needed for health reasons. Achieving balance in ventilation and energy efficiency is essential.
Step-by-step explanation:
The concept of air infiltration is crucial in understanding energy efficiency and ventilation in modern homes. Air infiltration happens when outside air enters a house through cracks around windows, doors, and foundations. To manage this, measures like weather stripping, caulking, and improved window seals are used to reduce heat transfer, which in the case of the example, equals the energy used by forty-six 100-W light bulbs. However, achieving a very tight house with long air turnover times may not be healthy, as it is important to maintain a minimum level of fresh air to supply oxygen and dilute household pollutants.
Improper water resource management and crowded housing can exacerbate issues related to poor ventilation. Ensuring proper screening of all doors and windows is essential for maintaining a balance between energy efficiency and healthy indoor air quality.Air infiltration refers to the process of outside air leaking into a house, which is managed by weather stripping and sealing.
