A key component of modern construction is verifying the degree to which a building envelope resists air leakage. This verification process, often mandated by code, involves specific procedures and requirements to assess the flow of air through unintentional gaps and cracks in the buildings structure. Such evaluation ensures that a completed construction project meets defined performance standards for energy efficiency and indoor environmental quality.
Adherence to prescribed standards offers numerous advantages. Reduced air infiltration minimizes energy consumption for heating and cooling, leading to lower utility costs and a smaller environmental footprint. Furthermore, controlled ventilation improves indoor air quality by preventing the uncontrolled entry of pollutants and allergens. In the past, building practices often lacked rigorous control over air leakage, resulting in significant energy waste and potential health issues for occupants. Contemporary regulations aim to rectify these deficiencies through mandatory assessments.
