In order to reduce environmental loads such as primary energy consumption and carbon dioxide emission, optimizing energy utilization systems in terms of the effective utilization of thermal energy, is an unavoidable process. We considered the optimization of energy utilization systems, including the cogeneration system (CGS), on Keio University Shonan Fujisawa Campus (SFC) under the condition of power transmission to another campus. First of all, we analyzed optimum introduction of the CGS with considering the exergy balance between demand and supply, based on the actual energy demand. Secondly, we examined the effectiveness of the systems with maximally utilizing the exhaust heat for air conditioning on SFC and introducing power transmission to another campus. As a result, the annual primary energy consumption and carbon dioxide emission could be reduced by 8% and 26% respectively, compared to the existing system. Furthermore, the peak power load on the commercial grid can be leveled through the year by a proposed manner of introducing and operating the CGS.
