ESCOs must have the demonstrated technical and managerial capabilities to address a broad range of building energy systems and provide a comprehensive set of energy services. Energy systems include, but are not limited to, heating, ventilation and air conditioning systems, lighting, windows, insulation and energy management controls, life safety measures that provide long-term, operating-cost reductions, building operation programs that reduce operating costs, other energy-conservation-related improvements, including improvements or equipment related to renewable energy, water and other natural resources conservation, including accuracy and measurement of water distribution and/or consumption, and other equipment, services and improvements providing energy efficiency. Energy services include, but are not limited to, an investment-grade technical energy audit and report; the design, acquisition, installation, modification, maintenance, commissioning, monitoring, and training in the operation of solutions installed in this project
