| Abstract |
This study aims to present basic data of opening design in the attic space for cooling energy conservation.The quantity of inflow in the attic space under Seoul climatic condition were computed. Then, cooling energy con-sumptions at sample houses were analyzed and compared with a non-attic case. Finally, CFD simulation were conductedto present the indoor thermal environment when openings in the attic space allow outdoor air 0ACH to 15ACH. Fromthis result, optimal opening sizes in the attic space were proposed and cooling effect of ventilation in the attic spacewas conformed quantitatively. |
