As summer weather surrounds us, prominent Texas real estate developer Marcus Hiles offers four basic tricks that will allow apartment hunters and homebuyers to dramatically lower their energy bills. The Chairman and CEO of Western Rim Property Services, Hiles is always one to follow his own advice. He employs these energy saving tips in all of the units he builds. The first thing he suggests doing is ensuring the use of windows with a solar heat gain coefficient of 0.22 to 0.24, including 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 says.
