As the temperatures go up in summers, notable Texas real estate developer Marcus Hiles suggests four tips to tenants and homeseekers to reduce their energy bills. As Chairman and CEO of Western Rim Property Services, Hiles follows his own practical guidance, utilizing all these tricks in every home he develops. To start with, he recommends windows with a solar heat gain coefficient of 0.22 to 0.24, just as the Cascade Low E Argon Gas Win Pro Series. With heat transfer, old windows from the 1980s lose up to 100 times higher energy as compared to a fully insulated solid wall. While older casements, transoms, and sliders are good to look at, having the newest windows and frames prevent air and energy leaks, cutting your heat loss by 75%, Hiles highlights.
