Federal government agencies are faced with significant budgetary challenges when trying to meet requirements for infrastructure renewal and mandates for increased energy efficiency. Much of the building stock owned and operated by the federal government is of the age where major renovation will be required to continue to meet the mission requirements.Additionally, there are numerous federal mandates requiring that agencies meet prescribed goals for energy efficiency and sustainability such as net zero energy. Major facility renovation projects have traditionally been funded with sustainment, restoration, and modernization (SRM) funds requiring large capital appropriations. These funds are becoming increasingly difficult to obtain under current budget constraints. Alternative financing vehicles for energy projects have significant limitations in the ability to fund large-scale renovations of buildings. These challenges require that the methods used to accomplish these requirements extend beyond what has traditionally been done.
