It doesn’t matter what climate your building is in; you’re probably paying your electric utility more for peak demand charges than you need to – a lot more. Charges for peak usage can be 30–70% of a total commercial or industrial user’s electric bill, no matter what your base use is. Through your roof material selection, you have choices. Learn why two buildings in different climates can achieve the same peak savings, proportionately, with a cool vinyl roof. Put demand charges on a diet.
