Weatherization plays a crucial role in enhancing energy efficiency by improving insulation and air sealing within buildings. When a structure is properly weatherized, it means that gaps and leaks in the building envelope have been identified and sealed, and insulation has been added or improved. This process helps to minimize the loss of conditioned air (either heated or cooled) from inside the building to the outside environment, thus reducing the amount of energy needed to maintain a comfortable indoor temperature.

By optimizing insulation, weatherization ensures that buildings retain heat during the winter and stay cool during the summer. This not only leads to a more comfortable living environment but also significantly lowers energy bills and reduces the overall demand for energy resources.

Other options do not directly relate to how weatherization contributes to energy efficiency. For instance, increasing solar panel efficiency doesn’t stem from weatherization practices, humidity levels might be influenced by various factors but are not a goal of weatherization, and the need for natural light does not relate to the insulation or sealing processes aimed at improving energy efficiency.
