• In this paper, seven cases with three different options for energy provision, PV, co-generation and all-electrified system, have been assumed for a detached house. In order to obtain an energy-saving effect, a new theory concerning the determination of running schedule for the co-generation system has been presented. On this basis, the outcomes for various options have been evaluated regarding the energy-saving, environmental and economic effects. The results can be summarized as follows: (1) A function relationship between the heat-to-power ratio and energy saving has been proposed. Moreover, expressions to calculate the minimum thermal utilization efficiency and the electric generating efficiency for the track electricity and track thermal operation modes also have been derived. (2) Energy supply systems using PV can achieve excellent effects considering each evaluating index. However, because of the high initial cost, the payback period is longer than for other systems, at more than 9 years. (3) The co-generation system can achieve energy-saving and environmental effects. In addition, with the remarkably low running cost, its payback period is less than 4 years. (4) The energy saving and environmental effect of the all-electrified energy supply system depends on the COP/efficiency performance of electricity consumption equipment. However, the economic effect is excellent compared with the reference system.
