Prominent real estate developer Marcus Hiles, discusses tricks that will enable apartment renters and homebuyers to considerably lower their energy bills. As founder and CEO of Western Rim Property Services, Hiles uses these energy saving suggestions in every apartment and home he builds. Always making sure windows are up to date with an appropriate solar heat gain coefficient of 0.22 to 0.24, such as the Cascade Low E Argon Gas Win Pro Series. Windows built in the 1980’s or earlier, often lose way more heat than an insulated solid wall. “While older casements, transoms, and sliders are beautiful, having the newest windows and frames prevents air and energy leakage, cutting your heat loss by 75 percent,” Hiles explains.
