What does residential weatherization involve?

Residential weatherization specifically focuses on making improvements that reduce air leaks and enhance the energy efficiency of a home. This involves a variety of techniques aimed at sealing air leaks, insulating walls, attics, and floors, and ensuring that windows and doors are properly sealed to minimize energy loss. By addressing these issues, weatherization not only improves the comfort of occupants but also leads to lower energy bills and reduced environmental impact. The emphasis is on optimizing the building envelope to maintain consistent indoor temperatures and reduce the workload on heating and cooling systems, which aligns directly with the goals of energy efficiency.

In contrast, the other options—improving aesthetic design, enhancing HVAC communication, and installing decorative features—do not directly contribute to the energy efficiency and functional performance of a home, which is the primary goal of residential weatherization efforts.
