Abstract
Economic advantage and CO_2 reduction extent of cogeneration system greatly depend on energy demand patterns, fuel costs and possibility of grid connection. The paper analyzes the basic characteristics of cogeneration system in economic and emission aspects and shows strategies necessary to maximize CO_2 reduction amount by the introduction of the system. The buildings analyzed in the paper are houses, offices, stores, hotels and hospitals, whose general energy-demand patterns are available. The result of the analysis shows that houses have the greatest potential to reduce CO_2 emissions among these building types, and reversed grid connection is the most important to maximize the potential. Combination of different types of buildings with energy network increases the economic and CO_2 reduction benefits, and the optimum combination of buildings is identified. The paper compares CO_2 emission amount for variety scenarios of strategies for introduction of cogeneration systems.
