The Facility Energy Decision System (FEDS) is an easy-to-use building energy efficiency software tool that quickly and objectively identifies energy efficiency improvements that maximize life-cycle savings. The Windows®-based program requires only minimal user experience and input to perform energy efficiency assessment screenings as well as detailed energy retrofit project analyses across a wide variety of building types. FEDS support energy efficiency and resilience assessment goals for single buildings as well as large multi-building campuses and installations. It simulates building systems, loads, and energy use and analyzes the cost and performance impacts of thousands of potential efficiency measures. FEDS values energy and demand savings based on comprehensive tracking of building and site-level use and estimates project costs to support robust economic evaluations and sound decision-making.
FEDS is available free of charge for use on federally funded projects and those projects funded and directly performed by a state government on a state-owned facility. A variety of paid license options are also available. Visit the FEDS website for more information and to submit a request.
