The secondary utilization of exhaust heat is consistent with the phased utilization of energy, and is especially effective for relatively low temperature operation such as heating, cooling and hot-water supply, etc. The cogeneration involves the simultaneous production of electric power and useful thermal energy. By recapturing and using some of the thermal energy normally discharged from power units such as engines and turbines, the cogeneratiori system can reduce system fuel requirements. However, a large fluctuation in demand for electricity, which is a notable characteristic of buildings, would trigger fluctuations in thermal production. Usually, the demadns of electric power and heat do not correspond with each other. So, it becomes important to evaluate the energy conservation effect on cogeneration systems. In this paper, the authors deal with the framing of the numeric simulation model of cogeneration systems and application of the model for hotel, department and office buildings. Throuth the analysis of energy conservation effect between conventional systems and cogeneration systems, the following items become clarified. 1) It is required to consider the haracteristics of demand fluctuation and partial load operation of power units, when framing the simulation model. 2) Applying the model, it is found out that there exist several effective systems and adequate operation methods by type of the buildings. 3) Moreover, the effective systems and adequate operation methods differ when compared by scale of building and by operational time period.
