Hiles’ rental homes, townhomes and apartments include energy efficient features without sacrificing luxurious amenities. The roof of each building is installed with highly reflective radiant barrier panels that can reduce heat transfer by up to 97 percent, and reduce indoor temperatures by 30 degrees. High-quality weather stripping and dual pane windows with a layer of argon gas and a solar heat gain coefficient of a minimum of 0.22 further assist in preventing heat loss. Indoors, every apartment is equipped with Energy Star rated appliances that not only reduce the resident’s carbon footprint, but also lower utility costs. For air conditioners, the industry standard is to install units with a seasonal energy efficiency rating (SEER) of 12 to 14, but Hiles insists that only units with SEER values of over 16 be used. As a result, residents across his 15,000 properties have lowered their carbon emissions by 32,000 tons, and accrued almost half a million dollars in savings.
