Energy management information systems (EMIS) are a broad and rapidly evolving family of software tools that monitor, analyze, and control building energy use and system performance. NREL’s Intelligent Campus program uses an EMIS to manage, save, and report energy use; test, demonstrate, and study the integration of renewable energy and energy efficiency technologies; and make operational decisions that minimize emissions or enhance resiliency.
