Weatherization, or “weatherproofing” your home involves making sure a significant amount of air isn’t leaking in or out of your home. If it is, some techniques to weatherize include sealing cracks/air ducts/lighting fixtures/window/doors, adding insulation, wrapping pipes, etc. Doing so will better keep warm or cold air in and save homes on utility costs. Local utilities have rebates for low income “weatherization kits” to target low-income populations that often spend the most on utility costs. According to the Office of Energy Efficiency & Renewable Energy, average annual savings from weatherization amount to around 30%; for this analysis we assumed that 20% of households would participate in this effort saving over 4,000 therms annually.
