As the weather heats up, prominent Texas real estate developer Marcus Hiles has four simple tricks that will help apartment hunters and homebuyers dramatically lower their energy bills. As founder and CEO of Western Rim Property Services, Hiles is always to follow his own advice, and he employs these energy saving techniques in every apartment and home he develops. First off, he suggests installing windows with a solar heat gain coefficient of 0.22 to 0.24. A common example is the Cascade Low E Argon Gas Win Pro Series. Through heat transfer, windows installed in the 1980s often lose up to 100 times more energy of fully insulated solid walls around the home. “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 notes.
