Abstract: A system for enforcing energy regulations is described. The system helps building departments maximize energy savings from the energy regulation enforcement process. The system is configured to optimize enforcement given a fixed level of enforcement resources within a building department. Optimization is achieved through the use of building science and sampling systems to structure building-by-building specialized inspection lists, which are delivered to building inspectors. Information collected during the inspection process is used to determine amounts of money that can be saved via complying or not complying with specific provisions of the energy regulations.
