As summers begin, celebrated Texas real estate developer Marcus Hiles gives four smart tricks to tenants and home seekers to decrease their energy bills. Hiles, Chairman and CEO of Western Rim Property Services, follows these energy saving techniques. First, he suggests utilizing windows with a solar heat gain coefficient of 0.22 to 0.24, such as the Cascade Low E Argon Gas Win Pro Series. Old windows from the 1980s lose up to 100 times more energy when compared to a fully insulated solid wall as heat begins to transfer. While older casements, transoms, and sliders are striking, having contemporary windows and frames prevent air as well as energy leaks, cutting your heat loss by 75%, says Hiles.
