Recent construction projects have now regenerated the existing city rather than reconstruction or redevelopment to create a new paradigm. While the aged houses are reviewed to distinguish between the repair, reinforcement and reconstruction stages, the modular construction system makes the most of space using the modular system, and the projection mapping system is combined with the existing space. Therefore, we will proceed with the research so that improvement and correction of future issues can be made.

Existing modular research has been mainly focused on S (shelter structure) and I (infill interior finishing material), and considerable research has been conducted, and the results are being proposed. However, in the case of the rest (exterior materials and windows, etc.), existing construction methods and materials are borrowed, and supporting hardware members and insulation materials are constructed on site, which acts as a factor hindering overall shortening of the construction period. That is, since the advantages and characteristics of modularity cannot be utilized in the absence of modular cladding, manufacturing of cladding is required. Therefore, it is necessary to develop a cladding system that can drastically reduce the construction period in factories while considering the structural characteristics of PC modulars.

This study proposes a temporary residential prefab modular structure to provide residential space to displaced people after a disaster. Patent cases related to prefab structures are collected for related design implementations, and classified. Space in temporary residential prefab modular structures must consider factors such as "Expandability", "Assembly and Disassembly", "Built-in Structure", and "Energy Efficiency", and the cases are classified into "Detailed Assembly Modular Type", "Modular Expandable Type", and "Space Unit Expandable Type". Overseas patents cases will be collected and analyzed in future studies for providing the efficient way for mass production for the lowest production cost.

Modular systems are widely used in various building types including housing, dormitory, and barracks. Steel studs have many advantages over other materials as construction components of modular buildings in terms of seismic performance, durability and maintenance. However, steel stud modular systems also have weakness in condensation resistance due to high thermal conductivity of steel. The purpose of this study is to investigate the condensation resistance of steel stud wall corner details in modular buildings by thermal simulation. The condensation resistance was evaluated by temperature difference ratio according to ISO 13788. The result showed that there was little difference between the alternatives of adding cavity and insulation. Separation of interstitial steel studs showed outstanding effect on the improvement of temperature difference ratio.

Precast Concrete apartments were main stream of domestic industrialized housing around 90's , and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel stud and Unit Box have their own merits an demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the Open System basis. In this study, the design standard for Unit house will be established coping with the established preparing standard for design specifications defined by Architectural Law and Promotion Law of Housing Construction. That is for design standard of industrialized private housing on the Open System basis.

Recently, large scale disasters have been occurred in rural areas. Most people suffering from the disaster live in the temporary containers. These could not provide the fundamental occupancy performances such as thermal insulation, ventilation and heating system. It is very important to rebuild the residence for sufferers quickly and safely. Because modular building system has some advantages such as short construction time, mobility, light-weight structure, modularity, flexibility and economical efficiency, it is expected that it could be easily applied to the disaster restoration. So, this research aims at developing the design model of modular building system for disaster restorations in fishing and agrarian villages. For this purpose, current counterplan for restoration was firstly investigated. Also the basic guideline was established through the investigation of current status of residence in fishing and agrarian villages. Finally, 2 types of design model such as single story residence and temporary accommodation facility were proposed. We could see that we could make the flexible building plan when applying the modular building system to the temporary housing for the sufferers.

The Hong Kong Housing Authority (HKHA) develops and implements a public housing programme to meet the housing needs of people who cannot afford private rental housing. The HKHA has an existing stock of about 740,000 public rental flats (PRH). According to the 2014 Policy Address, the Government aims to provide an average of about 20,000 PRH units and about 8,000 Home Ownership Scheme (HOS) units per year. We care for the environment. In developing new housing estates, we conduct thorough environmental studies such as microclimate studies and air ventilation assessment, and use passive design to harness the natural characteristics of our sites. We employ environment-friendly design and construction methods, using modular flat design, pre-cast and pre-fabricated construction techniques as well as recycled, green construction materials. We conduct Carbon Emission Estimation for all our projects, conserve the use of natural resources and reduce wastes throughout the life cycle of buildings. We care for people. We adopt the principles of Universal Design and Barrier Free Access for the convenience and welfare of people of all ages and abilities. We carry out Community Engagement to collect stakeholders' views and aspirations, and incorporate them in the design of our projects. We also carry out surveys of residents' views after the occupation of new estates to gauge our success and identify areas for improvement.

This study aims to provide a more comfortable environment for the external environment by designing a rotable dwelling that deviates from the conventional fixed residential concept. The round pillars, which are the center of the building, are constructed by placing the CFT (concrete Filled steel Tube) technique in place and assembling modular houses with columns. This study combines existing building techniques. Korea also needs to develop various related studies quickly.

In this study, Dr. Bae Kyu-woong of the Korea Institute of Construction Technology developed a concrete module that was lightweighted to 1700kN with KC modules and met housing performance standards. It solves Construction lifts problem that was the limit of the PC module, and is an innovative model that greatly improves Construction period and economics with boxed modules, and is manufactured in the factory by extruded molding in vibration, noise, fireproofing standards, etc., and has the advantage of excellent precision and high strength. Therefore, if the framing house of a precast concretecan only be standardized in construction, its potential for growth will be endless. To do this, standardization, standardization, and modularization of the design are essential.
