For the target goal of Zero-energy House construction in 2025, the government announced that the insulation regulations will be continuously enhanced. It has been predicted that high-performance insulation materials, such as vacuum insulation panel (VIP), should be used to decrease the thickness of outer walls. The aim of this study was to evaluate the performance of adhesively fixed external insulation and finish system (EIFS) with VIP. The energy performance of a base model with conventional internal insulation system and three alternatives of EIFS with VIP were analyzed by three-dimensional heat transfer simulation. Construction cost and convenience of each alternative were also evaluated and compared. As results, effective alternatives in terms of each performance as well as overall performance considering the weighting factors of each performance were suggested.

External Insulation Method is to place the insulation on the outside of concrete. External Insulation Method is better than Internal Insulation Method to the protection of structure. However, The phenomenon that External Insulation falling from the structure occurs frequently. Apply method of External Insulation is divided Wet Construction, Dry Construction and Wet & Dry Construction. The purpose of this study is to test Bonding Strength of External Insuation. Furthermore, on the basis of this study, External Insulation Method determines the effective development will be made.

This study proposed vision artificial intelligence-based automated supervision technology for external insulation and finishing system, and basic research was conducted for it. The automated supervision technology proposed in this study consists of the object detection model (YOLOv5) and the part that derives necessary information based on the object detection result and then determines whether the external insulation-related adhesion regulations are complied with. As a result of a test, the judgement accuracy of the proposed model showed about 70%. The results of this study are expected to contribute to securing the external insulation quality and further contributing to the realization of energy-saving eco-friendly buildings. As further research, it is necessary to develop a technology that can improve the accuracy of the object detection model by supplementing the number of data for model training and determine additional related regulations such as the adhesive area ratio.

To solve some problems that reveals in the exiting stickiness problem of the housetop, the housetop finishing impact layer can be displaced by the existing concrete block. By doing in this way, this need is rising that the excess cost should be reduced and the materials should be recycled in repairing. According to the above, this study is going to suggest the basic data on building and using of the dry process method by estimating and analyzing a overall determinate quantity through the experiment on the insulation performance among the capacity items on the outside insulation waterproof dry process suggested. In addition, choosing the building method according to the use, the peculiar property and the importance of the building can be possible by analyzing the defect causes happening in the rooftop insulation and waterproof, suggesting the better method and classifying the most proper choosing methods for the need of the building according to the importance of the main factors.
