There has been a growing movement in the development of buildings and homes that use sustainable material and are considered energy efficient: a movement that for decades has grown into a lifestyle both nationally and internationally. In fact, many new residential and business facilities are required to meet a certain standard of efficiency after construction before they are occupied. As for existing structures that may not meet the new standards of sustainability but want to, they can rely on the work of engineers like Lois Arena, a senior consultant at Steven Winter Associates, Inc.
