As the summer heats up, renowned Texas real estate developer Marcus Hiles notes four simple tricks that will enable apartment hunters and homebuyers to dramatically lower their energy bills. As Chairman and CEO of Western Rim Property Services, Hiles follows his own advice, employing each energy saving technique in every apartment and home he builds. First, he recommends windows with a solar heat gain coefficient of 0.22 to 0.24, such as the Cascade Low E Argon Gas Win Pro Series. Through 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 declares.
