Through thermal environment measurement and diagnosis of HVAC system, heating condition of the S station building was investigated and problems was grasped from before this study. On the basis of this study, improvement scheme was prepared for improvement of heating condition. In this study, effect of improvement scheme was confirmed for saving energy of the S station
building by CFD simulation and saving energy quantity was computed with improvement scheme. Results of this study are as follows. (1) The result of CFD simulation before improvement, heating of low rise space accumulate on a high temperature at high rise space of above 10m hight, thermal environment of 2nd floor area is presented badly. (2) The result of CFD simulation by improvement, the temperature is higher than 22.0℃ which is designed temperature of the S station building but the applied improvement in this CFD simulation was improved for outdoor air restraint in architecturally and attention of management is needed for better heating effect. (3) The result of saving energy quantity, 40.3% reduction can be saved by the case 1
improvement and 65.6% reduction can be saved by the case 2 improvement.
