전방막사의 단열개수로 인한 에너지 소비절감 효과에 관한 연구 = The Study on the Effect of Energy Conservation after Retrofit in Military Barracks of Front Line Region

다국어 초록 (Multilingual Abstract)

The purpose of this study is to compare the thermal and economic efficiency between the existing military barracks of frontal area and those which retrofitted on the basis of energy conservation. The results are as follows;
1) According to the standard design of combined military barracks of the Army, the K value of the roof is 0.520, the K value of the out-wall is 0.526. They are even below the national standard level of isolation of heat. Therefore in order to qualify the national standard level, the thickness of polystyrenefoam should be changed from 50mm of the present to 75mm.
2) In case of existing military barracks, the heat loss per each column which is attached to the outer-wall is 102 kcal/h. But in the barracks which are retrofitted, the heat loss can be lowered to 24kcal/h.
3) In case of existing military barracks, the heat loss between the wall and the slab of the first floor is 32,000 kcal/h in total. But if we retrofit the barracks, the heat loss can be diminished up to 25%.
4) If we retrofit the barracks, not only the isolation level of heat would satisfy the standard level but also the cost of heating might be decreased to a great degree. Also, Since the cost of retrofit would be returned in about three years, we can say it is economically efficient.
