While energy usage does decrease as U-factor drops, your utility bills depend on regional climate and energy costs. You can calculate the savings yourself by using RESFEN , the same computer model that ENERGY STAR and the Lawrence Berkley National Laboratory (LBNL) use to determine the energy savings data for ENERGY STAR qualified products.
