Total heat exchanger model based on experimental results was incorporated in the entire buildingmodel with the stay and internal generation of heat and with window opening-closing schedule, andenergy-saving effects of total heat exchangers were evaluated including regional features in Japan.Regional differences were found in the effects, and it was found that the reduction rate of heating andcooling loads was in the range of about 2 15%, and the reduction amount of heating and coolingloads was in the range of about 0.1 11 GJ. Also, based on the fact that cooling load increases due tothe installation of total heat exchanger in the regions under cold climatic conditions, the buildings in theregions with warm climate designed in the high air-tightness and high insulation specification. As aresult, it was found that heating load was reduced by about 35%.
