What is the potential impact of using ENERGY STAR-rated windows?

Choosing ENERGY STAR-rated windows can significantly reduce heat loss in the winter and heat gain in the summer. These windows are designed with advanced technologies, such as low-emissivity (low-e) coatings, insulated frames, and gas-filled spaces, which help maintain indoor temperatures more effectively. This results in lower energy costs due to reduced reliance on heating and cooling systems. By improving the thermal performance of a building, ENERGY STAR-rated windows contribute to enhanced energy efficiency, leading to savings on utility bills and a reduced carbon footprint. Overall, their primary function is to improve energy efficiency, which aligns with the benefits outlined in the chosen answer.
