| Abstract |
The purpose of this study is to develop high performance of exterior insulation precast concrete wall and evaluate performance of the wall for the basic, production, construction and energy. The result of this study as follows : 1) High performance exterior insulation precast concrete wall was developed that the insulation performance is 40% higher and the weight is 50% less than existed RC-Wall. 2) The basic performance of PC-Wall was allowable in ASTM and AAMA standards. 3) The production performance was secured as manufacturing production system and mass production would be able. The construction was taken about 40 minutes for each PC-Wall. 4) In comparison with interior insulation system, linear thermal transmittance and annual heating energy demand of exterior PC-Wall apartment were decreased 18.4~82.5% and 17.6% respectively. |
