Improper installation of air barriers in building construction can lead to several significant consequences that affect building performance, energy efficiency, structural integrity, and indoor environmental quality. Here's an in-depth exploration of the potential consequences of improper air barrier installation, along with examples illustrating these issues:
1. Increased Energy Consumption
One of the primary consequences of improper air barrier installation is increased energy consumption. Air leaks and gaps in the building envelope allow conditioned air to escape and unconditioned outdoor air to enter, causing the HVAC system to work harder to maintain desired indoor temperatures. This results in higher energy bills and reduced overall energy efficiency.
Example: In a newly constructed office building, improper sealing around window frames and door openings leads to air leakage. As a result, the HVAC system struggles to maintain consistent temperatures, leading to increased heating and cooling costs for building owners. Over time, the building's energy consumption far exceeds the anticipated levels, impacting operational expenses and environmental sustainability goals.
2. Compromised Thermal Comfort
Air leaks caused by improper air barrier installation can result in compromised thermal comfort for building occupants. Drafts, cold spots, or uneven temperatures near windows, doors, or walls can create discomfort and dissatisfaction among occupants. In extreme cases, it can lead to complaints and poten....
