As the temperatures rise in summers, well-known Texas real estate developer Marcus Hiles suggests four basic hacks that will enable apartment seekers and homebuyers to significantly drop their energy bills. As Chairman and CEO of Western Rim Property Services, Hiles follows his own tricks, utilizing each energy saving technique in every apartment and home he builds. Firstly, he suggests windows with a solar heat gain coefficient of 0.22 to 0.24, such as the Cascade Low E Argon Gas Win Pro Series. With 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 good-looking, having the newest windows and frames averts air and energy leakage, reducing your heat loss by 75 percent,͟ Hiles says.
