Check the fit before chasing energy savings

A low-cost, renter-aware first step to lower home energy use is sealing drafts around windows and doors, as air leaks can account for 25% to 40% of heating and cooling energy use in homes^[1]. You can fix this affordably using weatherstripping tape, removable caulk from a hardware store, or placing a rolled-up towel at the base of doors^[2].

While these DIY methods are safe and reversible, applying caulking or weatherstripping incorrectly can sometimes leave residue or damage paint when removed, so it is best to use removable products designed for renters. More extensive insulation measures or permanent window replacements require landlord approval and professional help.

Your immediate next action is to check your windows and doors for drafts by feeling for incoming chills so you know where to apply weatherstripping tape or caulk^[3].
