Recently increasing high-rise building cleaning on the exterior walls of high-rise buildings, there has been increased interest. Building exterior cleaning is cleaned by a cleaning robot and how to clean the exterior walls of the building and exterior glass cleaned by personnel. Number of stories in the building increases, being carried out by personnel cleaning the outer wall as there is a limit order to overcome this method. therefor, this study is a new exterior wall cleaning device has been proposed.

The university building which is located in Daehak-ro where the commercial buildings are. The color of the building exterior and the signs are various to distinguish. To recognize the building exterior among the surrounding areas, it needs visual and bright color on it. The blue and white selected from the color of university identity. The core of the building is treated as a tower In vertically and white color is painted. And the rest parts of the building are treated horizontally and blue color is painted. The color of the building exterior shows the visual effects not only symbolism but attention.

With the progress of national policy researches on the modular construction, many studies have been conducted regarding the standardization of interior building materials. However, studies on the standardization of exterior building materials are still insufficient, and there are no dedicated exterior materials for modular construction. In this regard, this study investigated the necessary of standardization through the analysis on 7 kinds of exterior materials used in general buildings and exterior building materials applied to modular apartment houses in order to establish design criteria for the standardization of dedicated modular exterior materials. Based on the analysis results, assembly reference plane in conjunction with inside dimensions was set, and panelizing standardized in five parts was proposed to solve the problem of low exterior material standardization rate. It also proposed elastic gasket and steel bracket details that can compensate for the fabrication errors of unit boxes and construction errors in stacking.

Most of the building exterior wall cleaning robots use a water jet device for spraying water. However this method is sprayed excessive water usage than water quantity required for cleaning. And setting weight of the water pump cleaning device increase the weight of the building exterior wall cleaning robot. Therefor, this paper suggest that the mechanisms scatter minimal cleaning water using a spinning device of the building exterior wall cleaning robot.

The presence of thermal bridges in a building envelope cause additional heat loss which increases the heating energy. Given that a higher building insulation performance is required in these cases, the heat loss via thermal bridges is a high proportion of the total heat energy consumption of a building. For the dry exterior insulation system that uses mullions and transoms to fix insulation and exterior materials such as stone and metal sheet, the occurrence of thermal bridges at mullions and transoms is one of the main reasons for heat loss. In this study, a dry exterior insulation system using the truss insulation frame (TIF) was proposed as an alternative to metal mullions. To evaluate the building envelope performance, structural, air-leakage, water-leakage, fire-resistance, thermal, and condensation risk tests were conducted. In addition, the annual energy consumption associated with heating and cooling was calculated, including the linear thermal transmittance of the thermal bridges. As a result, the dry exterior insulation system using TIF achieved the allowable value for all tests. It was also determined that the annual heating load of a building was reduced by 36.7 % when the TIF dry exterior insulation system was used, relative to the dry exterior insulation system using steel pipes without additional insulations.

3D printing technology can be applied to various industries, and is trapped by major technologies that change existing manufacturing processes. 3D printing materials must satisfy designability, economy and productivity, and building materials are required to have strength and economy secured technology. 3D printing technology of construction field can be divided into structural materials and internal and external materials, and is mainly done by extruding and adapting. Particularly when it is applied as an exterior materials, it is mainly applied to an unstructured exterior materials and high accuracy is required. The exterior materials can be used as a cement composite materials, it is suitable also for a lamination type, and the role of a cement base composite material is important. In this research, we developed a cementitious base binder applicable as a 3D printing exterior materials, confirmed high temperature strength characteristics for application as an exterior materials of buildings and confirmed its possibility.

Energy load of building affected by insulation performance of building's exterior. and insulation system can be classify interior insulation, exterior insulation, sandwich insulation according to install place of insulation. but within interior insulation system, corner wall and the cross outer wall-slab insulation part may occur thermal bridges. And then, within exterior insulation system is more superior insulation performance than interior insulation, but it has difficult to apply, easily broken at high building because of strong wind load. And also difficult to maintenance exterior insulation system. So, in this study, to found requirement performance of cast-in-place sandwich insulation system that is superior insulation performance and easy construction and maintenance. requirement performance of cast-in-place sandwich insulation system is 1) To avoid thermal bridges in the insulation performance, 2) Both sides concrete wall can be composite action in the structural performance. Because of this study, can develops cast-in-place sandwich insulation system and this insulation system contribute to improve insulation performance of apartment-house and high building.
