Abstract
The cogeneration system (CGS) has been expected to play an effective role in terms of energy conservation. To enhance the efficiency of the CGS in the actual situation, constructing clusters of the various energy demand would be effective. In order to examine the energy conservation effect of the CGS on the actual situation, the primary energy consumption of Keio University Shonan Fujisawa Campus (SFC) was calculated based on the actual energy demand assuming replacement of the existing CGS with four different sizes of the CGS. The energy conservation effect of the CGS was also examined for the case of greater reutilization of the exhaust heat among the buildings at SFC and providing generated power of the CGS to other campuses. As a result, the energy conservation effect could be enhanced if the load factor of the exhaust heat reutilization and the power generation are increased by constructing appropriate demand clusters among the plural buildings or campuses, as well as it would be important that the CGS operation could lead to the curtailment of the peak power load on the grid.
