The earth is a natural material that has natural healing power,,as a natural ingredient, it brings environmental friendliness, emotional. In this Research, for one of the methods to expand the benefits as a healing space, Construction of the Earth design and earth construction methods have been actively used for effectiveness of the Earth in the construction of the interior with the oriental medical clinic. By utilizing the concept of biophilic design as a healing environment design, symbolizing nature such as color, light, plants, flowers, and natural materials such as earth and wood was directed as oriental medicine interiors. In addition, the space was divided according to the movement of patients and used different Earth construction method to each of the space for the distinction and differentiation according to the characteristics of each space. At this time, the Earth was constructed with materials and finishing materials that meet the highest grade of HB (Healthy Building), an eco-friendly building material certification grade without additives, so that the interior and medical treatment concept can be done at the same time. By using Earth as the basis of elements in the construction, and the design of healing space, patient the concept of Biophillic as a healing environment design. This may serve as a technical, aesthetic, and cultural basis for constructing a healing space by Earth in the future-oriented alternative, it may lead to necessity of eco-friendly and ecological architecture, and it may be an opportunity to expand the application area of earth in architectural design.

Although the interest for earth architecture has been expanded and settled as a part of modern architecture, precisely calculating the ratio of water content in practice is still difficult and the calculation is based on empirical analysis yet. This causes many problems in durability and maintenance of earthen architecture. Therefore, this study investigated to find the easiest way to correctly calculate the appropriate level of water content ratio (AWCR), which can be used in practice. Until now, the workers have checked the AWCR based on their own experience with popular but vague manuals. On this awareness, we studied the several testing methods and found the dropping test which uses the pattern of shape after the sample is dropped. In this point, we studied and developed the definite testing method in terms of process, and shape discrimination. Also we suggest the test recording sheet by using the cobalt chloride($CoCl_2$) whose color is instantly changed when contacts with the moisture. It is believed that this result can help improving the quality and durability of the earthen architecture using the rammed earth method and the efficiency in practice.

We intend to offer theoretical bases of earth construction technology through the analysis of cases of brickworks and plastering works in the city of Gumi, Kyeongsangbukdo. We search for those instances of earth buildings to confirm the trend that earth construction is recognized as environment-friendly, sustainable and newly spotlighted field to alternatives of building construction. We made a frame of analysis through theoretical consideration about earth construction and prior study. Then, we analyzed the selected buildings which is selected by priority in the city of Gumi as authorized preservation value, cultural assets and recently built modern constructions. We found out some problems in structural strength, durability and fire proofing and the invisible development of technologies of earth construction method in this case analysis.

Results from tests for what mixing rate of soil and sand is proper for the rammed earth and for how much additives are optimum are as under. 1) In the test to evaluate what mixing rate of soil and sand is desirable, peptizing property and surface sticking rate are found similar in its degree, but compression strength is found most stable when the ratio of soil and sand mixing shows 30:70 which indicates the best mixing rate of soil and sand. 2) In a test to add hydrated lime, compression strength, peptizing property, and surface sticking rate are found best when the mixing rate of soil and sand shows 23:7. 3) In a test to add sea weeds, the peptizing property goes down at 75% of sea weeds input a little bit more than at 100%, but compression strength shows best at 75% which is thought to be the best rate. 4) In a drop test, more soil powder mixed, the sticking strength gets better and more sands are contained, the sticking strength gets far worse to be scattered in powder type. 5) As concluding all results mentioned in the above item, the most desirable mixing rate of soil, sand, and hydrated lime is found to be 23:7:70 for the rammed earth where compression strength, peptizing property, and surface sticking rate are best.

Vernacular perspectives had been ignored in the movement of modern architecture. This study's purpose was to review vernacular perspectives and to identify vernacular characteristics of earth architecture. Six representative contemporary earth architects were selected, and then their works were analyzed. Themes of vernacular architecture based of Frampton's critical regionalism were emerged. Findings were as following: 1) constructed by considering the local climate and the region's natural characteristics, 2) constructed with local materials seeking integration of structure and finishing work, 3) having tectonic form included regional characteristics, 4) creating space of various senses and expression of texture through earth modeling, 5) presenting homogeneity of sense of place between site and architecture, and 6) pursuing ecological and sustainable architecture. These characteristics of contemporary earth architecture reflect the vernacular architecture inherited continually in architectural history. Therefore, contemporary earth architecture has been in line with contemporary architecture aiming for sustainability.

The purpose of this study is to analyze the legislation types and prescriptions of American earth building codes. The process of this study is as follows: (1) To understand the legislation background of American earth building codes, this study investigated the history and present state of earth building techniques which is used in USA. (2) To understand the legislation method and procedure of American earth building codes, this study investigated the legislation system of American building codes and the process of model building codes development and adoption. (3) To provide basic data for the legislation of Korean earth building codes or guidelines, this study analyzed American earth building codes about adobe, compressed earth block and rammed earth. The result of this study is as follows: (1) To meet need of a single coordinated set of national model building codes in the United States, the nation's three model code groups decided to form the International Code Council and the first edition of the International Building Code was published in 1997. In the International Building Code there are prescriptions on adobe construction. (2) There are three legislation types of earth building codes in USA. First is to use prescriptions of International Building Code on adobe construction. Second is that State governments establish and issue a separate document under its own title. The last is that local jurisdictions adopt International Building Code with amendments or additional rules. (3) On the base of analysis of American earth building codes, this study proposed the legislation process and direction of Korean earth building codes and guidelines.

This study is aimed to apply basic data to planning earth building through analyzing characteristics of earth building. For doing it, we investigated a research paper in advanced countries(New zealand, Australia, etc.) that has been used for earth building standards for a long time, and then we corrected inadequate standards that would apply our earth building environment. As a result, we can devide earth characteristics into three parts that are materials, plan, and maintenance and repair. First, as material selection is very important factor, a general plan is possible to change in accordance with what material is selected. These methods that made mud brick, pressed earth block, rammed earth, cob have been well used during the current 30 years in earth building. Second, the plan is composed of site select and architecture plan. In architecture plan, we should consider from foundation to eaves protection, and in site selection, consider sides of the environment and the social. Third, we should always check a periodical inspection through watchful observation because earth buildings need more time and efforts in maintaining and repairing than others.

Housing issues such as mushrooming slums remain as chronic in most developing countries. Due to the state's restrained capacity, the housing-vulnerable's self-help approaches have been increasingly inevitable and vital for addressing the housing issues. However, there are still two challenges: securing good quality with economic efficiency, and climate change mitigation and adaptation. This study aims at doing an architectural experiment by developing and educating the production of eco-friendly interlocking stabilized soil bricks (ISSB) by employing vernacular materials and technologies for housing-vulnerable communities in Indonesia. In collaboration with a local architectural NGO, the study features a co-creation workshop in which 40 evicted households participate in the whole process. Soil analysis, mixed design, compression tests, and economic analysis are carried out. This paper illustrates that ISSB also has a high potential as an alternative to a burned brick or a cement block. The application of ISSB to self-help housing is expected to have socioeconomic and environmental effects, thereby facilitating the housing-vulnerable's self-help approaches and contributing to addressing the housing challenges in Indonesia.
