Texas real estate investor, Marcus Hiles, urges us to follow his four simple tricks that will permit rental pursuers and homebuyers to dramatically lower their energy bills. As CEO of Western Rim Property Services, Hiles tracks his own advice, using each energy saving technique in every property he develops. He urges people to put in new windows with a solar heat gain factor of 0.22 to 0.24, just like to the Cascade Low E Argon Gas Win Pro Series. Longstanding windows from the 1980s and beyond lose up to 100 times more temperature than an 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 states.
