Renowned Texas real estate developer Marcus Hiles notes four simple hacks to help apartment and home hunters to dramatically lower their energy bills as summer heats up. Hiles employs each of these tips in every apartment and home he builds as Chairman and CEO of Western Rim Property Services. First, Hiles says homeowners should install windows with a solar heat gain coefficient of 0.22 to 0.24, for example, the Cascade Low E Argon Gas Win Pro Series. Because of heat transfer, old windows from the 1980s lose up to 100 times more energy than a fully 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 points out.
