Alterations (new construction) shall comply with the International Energy Conservation Code. Where there are reconfigurations of the space or new doors or windows, any such new element is required to meet the International Energy Conservation Code. Elements within the building that are not being affected do not need to be evaluated and do not need to comply with the energy provisions. Essentially the entire building is not required to meet the energy provisions; only a degree of possible improvement in the energy performance of the building is intended to be achieved by making the new elements meet the IECC. In certain cases where the reconfiguration of the space might have resulted in the creation of new spaces the newly created space should be evaluated as a whole for compliance with the energy provisions even though some of the element within the space might actually not have been altered. Likewise, in a case where an existing mechanical system is being extended to other areas or new ductwork is being installed to reconfigure and reroute the ducts to various spaces, it is only required to have the new elements meet the energy provisions and not the entire system.
