Summer is heating up, and renowned Texas real estate developer Marcus Hiles would like to offer four simple tricks that will give apartment hunters and homebuyers the ability to dramatically lower their home energy bills. As founder and CEO of Western Rim Property Services, Hiles follows these energy saving tips in each apartment and home he builds. His first suggestion is to ensure you are using windows with a solar heat gain coefficient of 0.22 to 0.24, like the Cascade Low E Argon Gas Win Pro Series. With heat transfer, windows that haven’t been updated since the 1980s lose up to 100 times more energy than fully insulated walls. “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.
