If you are interested in purchasing a home, use this checklist to assess new homes for sale. The list below includes information on the 2009 IRC for Alabama. When builders meet or exceed these requirements, it’s a good indication of quality construction. Energy efficient homes are more comfortable, cost less to operate, and reduce air pollution. This checklist doesn’t cover every aspect of the Alabama energy code, but it addresses the requirements that are easiest to identify and understand after construction is complete. With this information, you can determine whether a new home likely meets minimum energy efficiency requirements.
