Anthem is designed to bring you closer to the natural world and every effort has been made to protect that world. Starting with the 700 acres (40% of Anthem) committed to permanent open space and parks. Those parks are landscaped with native, drought-tolerant plants. Which, in turn, are irrigated with reclaimed water. Same goes for the 25,000-plus trees that have been planted. Meanwhile all Anthem homes are built to achieve a 70.0 or better HERS (High Energy Rating System) score, meaning they meet an exceptional standard of energy efficiency. Best of all, environmental responsibility on our part means lower energy bills, for you.
