Balcony in a house is essential to indoor thermal environment control. When balcony is extended, problems would be made such as noise, dew condensation, overheating energy, atc. However, occupants and contractors of a house for installment sale are prefer to extend balcony space of house. Now, many construction companies design apartment considering balcony remodeling.. Occupants considering balcony remodeling need information of cost, energy efficiency, forms by balcony remodeling. But, construction companies are not insufficient to furnishing information of balcony remodeling. When balcony remodeling is indispensable, occupants must consider cost, forms, energy efficiency for balcony remodeling. So, this paper compare unextended balcony remodeling with 5 case on heating load of heating period and increasing rate of heating load and increasing heating area.
Result of comparing increasing rate of heating load with increasing rate of heating area is best of case 2 on energy efficiency. As a result of comparison between case 2 and case 3, case 2 is better than case 3 in terms of heating load even though the comparison is same in terms of heating area, Also as a result of comparison between case 2 and case 4, case 2 is better than case 4 even though the heating area of case 4 is smaller than case 2. Also case 4 is not better for each case of heating load and energy efficiency. Moreover, case 5 was simulated to find model's bearings , 3 type - the west-southwest, due south, the east-southeast. Result of simulation by model's bearings doesn't give a lot of influences to bearings. Synthetically, when occupants extent balcony space until 5 type of case, case 4(only front balcony remodeling) is void and case 2(only all room balcony remodeling) is the best among others. Balcony of house is important to indoor thermal environment. Balcony remodeling is formed carefully considering as selection of remodeling type. |
