Energy management is a broader system integration technology than conventional energy saving technology. It also emphasizes efficient operation of energy systems. In part 1, we introduced this ...technology; explained the detailed method of constructing the best mixed system in practical case studies; proved that the combination of the heat storage system using midnight power service and the gas co-generation system with the joint use of electricity/gas meets the requirements of both energy conservation and economic efficiency. In this part, we analyze the practical operation data of 1993 to prove that the best mixed system was best in practice. Additionally we refer to studies on heat storage tanks, and discuss the verification of CO_2 and NO_x content from the standpoint of environmental protection.
In the past, the energy system in a building and group of buildings was determined mainly on the basis of economical rationality on the side of consumers, but the present research has helped to ...clarify the concept of "energy management". It has been attempted to establish this concept as a practical business method for constructing an energy system aimed at effective use of energy and natural resources, that is, their saving and increasing economical effects. Also, this concept premises a "unified energy system" by coordinating the consumer side with the supplier side, as well as considering the special characteristics of various types of energy supplied to buildings. This report presents the construction method of energy-system unification based on energy management, discusses cases of urban development projects and clarifies the validity of the best mixed system.
