The term "weatherization" refers specifically to measures taken to improve energy efficiency and protect a home against the elements, particularly in terms of weather. This process involves various enhancements such as sealing gaps and cracks, improving insulation, and installing weather stripping to reduce air leaks and energy loss. By effectively weatherizing a home, homeowners can not only lower their energy costs but also enhance the comfort within the home by maintaining a stable indoor temperature.

Other options relate to different aspects of home improvement or building requirements. Enhancements made for aesthetic appeal focus primarily on the visual aspects of the home, rather than its function or efficiency. Compliance with local building codes pertains to adhering to regulations set by authorities, which may not necessarily relate to energy efficiency. Updates to electrical systems, while important for safety, do not fall under the umbrella of weatherization, which is focused on protecting the home from weather impacts and improving energy performance.
