This paper presents general characteristics of cogeneration system (CGS) for the reduction of carbon dioxide emission and economy compared to the conventional systems. Applying the method reported previously, the paper compares the CGS characteristics for types of cooling systems, building types, and locations in Japan. The result shows that absorption coolers are superior to electric coolers for the reduction of carbon dioxide, but the extent is not significant and it is reversed when the power plant efficiency becomes greater than 45%. The result also shows that when the systems and operation patterns are selected from economic points of view, CGS sometimes increase carbon dioxide more than the conventional systems without CGS. This tendency is most apparent in offices among different types of buildings. The CO_2 reduction rate with CGS is higher in northern cities with larger heat demand than southern cities in Japan, but the tendency is reversed in the case of stores, whose cooling demand is significantly high.
