As the summer begins to heat up, prominent Texas real estate developer Marcus Hiles offers four simple tricks that will allow apartment hunters and homebuyers to dramatically lower their energy bills. Hiles is the Chairman and CEO of Western Rim Property Services and is always one to follow his own advice. He employs these energy saving tips in all of the apartments and homes he builds. The first thing he suggests doing is installing 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 says.
