“…Simultaneously, detailed design and offsite fabrication of building components, under controlled factory conditions, using the same materials and designing to the same local building codes and standards as site-built facilities take place. The prefab components are then delivered and assembled on-site to reflect the identical design intent and specifications of the most sophisticated site-built facility, without compromise [48]. The ensuing section features an example of on-site prefab assembly.…”

Performance of Modular Prefabricated Architecture: Case Study-Based Review and Future Pathways

Even though tightened building energy efficiency standards are implemented periodically in many countries, existing buildings continually consume a momentous quota of the total primary energy. Energy efficiency solutions range from material components to bulk systems. A technique of building construction, referred to as prefabricated architecture (prefab), is increasing in reputation. Prefab encompasses the offsite fabrication of building components to a greater degree of finish as bulk building structures and systems, and their assembly on-site. In this context, prefab improves the speed of construction, quality of architecture, efficiency of materials, and worker safety, while limiting environmental impacts of construction, as compared to conventional site-built construction practices. Quite recently, a 57 story skyscraper was built in 19 days using prefabricated modules. From the building physics point of view, the bulk systems and tighter integration method of prefab minimizes thermal bridges. This study seeks to clearly characterize the levels of prefab and to investigate the performance of modular prefab; considering acoustic constrain, seismic resistance, thermal behavior, energy consumption, and life cycle analysis of existing prefab cases and, thus, provides a dynamic case study-based review. Generally, prefab can be categorized into components, panels (2D), modules (3D), hybrids, and unitized whole buildings. On average, greenhouse gas emissions from conventional construction were higher than for modular construction, not discounting some individual discrepancies. Few studies have focused on monitored data on prefab and occupants' comfort but additional studies are required to understand the public's perception of the technology. The scope of the work examined will be of interest to building engineers, manufacturers, and energy experts, as well as serve as a foundational reference for future study.

“…In general, the Ondol system was constructed by the wet construction method on site. Nowadays, the modular construction method with prefab Ondol panels is increasingly adapted in residential buildings to enhance the construction quality and shorten the construction period [26]. The use of prefab Ondol panels can make buildings lighter than those made by the wet construction method as well as provide an opportunity to reduce construction waste [27].…”

In South Korea, radiant floor heating has been used from old housing to the recently constructed residential buildings, which is called “Ondol”. The Ondol system is generally a water-based system and it uses hot water as a heat medium provided by boilers fueled by natural gas. With great effort to reduce greenhouse gas emissions, electric Ondol panels have been increasingly applied to the recent residential buildings for floor heating. While the prefab electric Ondol panels were developed with the demand for dry construction method, the information about the prefab electric Ondol system is not sufficient. For the present study, the thermal performance of the prefab electric Ondol panels was investigated through field measurement. In addition, the heating energy and economic performance of the electric panel were compared with the conventional Ondol system. As a result, a significant surface temperature difference was observed. Moreover, the heating cost for the prefab electric Ondol system was more expensive than the conventional system, even though a heat loss was observed by the operation of the conventional system.

Housing as one of the most basic needs of human being has received much attention. As a physical shelter, it is a fundamental need in each family. The need to housing has been increased based on the population increase in cities and its high density and it is a big problem in cities. High price of housing and lack of quality including construction materials to form and cultural quality is one of the greatest concerns of most of families. The study to create methods or types of design is necessary to provide comfort and many suitable housing indices and quality indices. Quality issue in housing increases the price. To reduce construction time and improvement of construction operation, modular building is used in the world. This method is a good model in construction for housing mass production. It should be considered that housing as living place of human being should be mostly regarding cultural issues than a symbol for the life and survival of human being. The study design is descriptiveanalytic. The data is collected via existing articles and resources to present a strategy to eliminate the problem of cheap housing. The problem of cheap housing gives some feedbacks regarding the materials or climatic and cultural patterns of society and also it creates problems in society and people as low-income class. The present study aimed to approach two paradoxes of cheap price and quality (including materials and culture).
