Abstract
The Korean government has set the goal of "Green Development" as a direction of national growth. For the target goal of Zero-energy House construction in 2025, the government announced that the insulation regulations will become stricter. It has been predicted that high-performance insulation panels, such as vacuum insulation panels(VIPs), should be used to decrease the thickness of the outer walls. The energy performance of a base model of conventional internal insulation system with conventional insulation panel and three alternatives of dry type external insulation system with VIPs were analyzed by three-dimensional heat transfer simulation. Construction cost and convenience of each alternative were compared. As results, outstanding alternatives with VIPs were suggested according to the combinations of weighting factors of energy performance, construction cost and convenience.
