Traditional building technique has been used as the main technology in the field of architectural heritage conservation in South Korea. It has remained this way with very little resistance until now. But the time has come to question the appropriateness of traditional technique as conservation technique. In this paper a study was done on the properties of the traditional technique and the architectural heritage conservation technique in order to define the appropriateness between the two techniques. As a result the traditional technique was found to be unfit for conservation technique. The reasons are as follows. First, there is a time gap between the traditional technique and the time when the heritage was first built. Second, conservation work is about retaining the values of being a heritage while the traditional technique is about safeness and practicality. Third, the use of traditional technique comes with using the tools of its time which cannot ensure the safety of the heritage. The traditional technique must be looked upon as one of an option in the field of conservation. We must develop a better conservation technology by finding balance between the traditional technique and modern science. And further more an aggressive investment must be made in order to realize this objective.

최근 2008년 화재로 소실되었다가 복구된 숭례문(崇禮門)의 단청 문제가 제기되면서 문화재 보존에 있어서의 전통기술 적용 문제가 논쟁거리가 되었다. 본고에서는 문화재 보존에 있어서의 전통기술의 의미를 살펴보고자 하였다. 일반적으로 전통기술에 대한 이해는 기본적으로 '전통'에 대한 관념에 기초하고 있다. 전통은 '고정불변하는 존재'가 아니라 '계승 발전하는 존재'로 보아 '살아있는 존재'로 규정되며, 그에 따라 '무형문화재로서의 전통연행, 전통공예 등'은 '고정된 실체를 가지고 있지 않는 것'으로 규정하고 있으며, 그에 따라 문화재 보존의 기본원칙인 '원형 보존'에서 '원형'이라는 것이 무엇인지를 정확히 규정하기 어려운 존재로 보고 있다. 한국의 경우 이렇게 원형을 규정하기 어려운 '무형문화재로서의 전통기술'이 유형문화재의 보존현장에 적용될 때 그 개념이 명확히 하지 않음으로 인해 보존 현장에서 여러가지 문제를 야기하고 있다. '전통기술'의 적용범위와 한계에 대한 논의 없이 현장에 적용되기 때문이다. 즉 '전통재료'를 사용하여 '전통기술'로 수복을 하는 것이 허용되는 것은 어디까지이며 문화재의 보존에서 이것이 어떠한 의미를 갖는가에 대한 논의가 결여되어 있기 때문이다. 본고에서는 이러한 전통기술의 적응문제를 국제적인 보존원칙 변화 과정의 검토와 함께 고찰해 보았다. 이러한 고찰 결과 '무형문화재로서의 전통기술'의 보존도 중요하지만 '유형문화재에 남아 있는 기술', 더 나아가 '제작 당시의 기술을 담고 있는 원래의 재료 보존'이 더욱 중요한 문제라는 점이 고려되어야 한다는 점을 강조하고자 한다.

Many cities in Japan retain older city structures with buildings in traditional form and style. Visitors are fascinated by charms and tranquility of pre-modern life styles. Architectural features of olden days are well conserved or carefully restored on purpose. In the case of Kawagoe city near Tokyo, local residents are largely replete with visitors without being necessarily aware of slow commodification of historic spaces. Kawagoe is yet socio-culturally sustainable and financially fit. This paper intends to analyse conservation strategies, with focus on architectural heritage, taken for the historic city of Kawagoe. With the population of 300,000 in the suburb of Tokyo, it is one of the best known historic cities in Japan. Kawagoe grew as a merchant city since 1700s, and it once reached to a major port of silk trade en-route to Edo (Tokyo) from northen provinces. Tourism industry is discovered as a key element in the conservation strategies applied to revitalize historic city center, Ichibangai, an important cultural heritage site with special reference to kurazukuri. This paper argues that augmentation of conceptions in architectural heritage is not only advantageous for the conservation of historic urban environment but it also provides opportunities for sustainable urban renewal.

The purpose of this study is to analyze the diversity of architectural characteristics of traditional Hanok using Pyonjakbub(變作法). The roof is essential element of Hanok and the proportion of the roof accounts for about a half of the Hanok elevation. The shape of a roof of Hanok has made by the structural method like Pyonjakbub. For this study, the investigation report of 'Korean traditional houses' and 'Cultural assets of wooden traditional house' published by Cultural Heritage Administration were used as it's references. The results of this study are as follows; Pyonjakbub is appeared differently according to the region and the house dates and it has strongly influenced the architectural characteristics of traditional Hanok-the width of a room, the cross section of inner space of a roof and the length of eaves, etc. In other words, the architectural characteristics of Hanok will be changed by using different Pyonjakbub. Using the proper Pyonjakbub, we will provide more satisfaction to the client who wishes to live in Hanok.

Traditional wooden buildings deform over time and are vulnerable to fire or earthquakes. Therefore, traditional wooden buildings require continuous management and repair, and securing architectural drawings is essential for repair and restoration. Unlike modernized CAD drawings, traditional wooden building drawings scan and store hand-drawn drawings, and in this process, many noise is included due to damage to the drawing itself. These drawings are digitized, but their utilization is poor due to noise. Difficulties in systematic management of traditional wooden buildings are increasing. Noise removal by existing algorithms has limited drawings that can be applied according to noise characteristics and the performance is not uniform. This study presents deep artificial neural network based noised reduction for architectural drawings. Front/side elevation drawings, floor plans, detail drawings of Korean wooden treasure buildings were considered. First, the noise properties of the architectural drawings were learned with both a cycle generative model and heuristic image fusion methods. Consequently, a noise reduction network was trained through supervised learning using training sets prepared using the noise models. The proposed method provided effective removal of noise without deteriorating fine lines in the architectural drawings and it showed good performance for various noise types.

Air lime is a traditional building material of Korea. It had been used in roofs, walls, floors and masonry joints of traditional buildings until the advent of Portland cement. However, due to its low strength and durability, the lime is currently avoided as a repair or restoration material for the preservation of architectural heritage. Furthermore, due to the current practice of using hydraulic materials such as Portland cement, understanding of the material characteristics of air lime is very poor in practice. In this context, this study intended to improve the mechanical properties of the air lime mortar by reducing water contents, and also the carbonation reaction of the mortar was quantitatively evaluated to clearly understand the characteristics of this material. Accordingly, air lime mortar with a water-to-binder ratio of 0.4 was manufactured using polycarboxylate-type superplasticizer. During the 7 days of sealed curing period, the mortar did not harden at all. In other words, there was no reaction required for hardening since it could not absorb carbon dioxide from the atmosphere. However, once exposed to the air, the compressive strength of the mortar began to rapidly increase due to the carbonation reaction, and the strength increased steadily until the 28th day; after then, the strength development was significantly slowed down. On the 28th day, the mortar exhibit a compressive strength of about 5 MPa, which is equivalent to the European standard regarding strength of hydraulic lime used for preservation of architectural heritage.

San-ja is one of the main members consisting of the roof of traditional wooden buildings in Korea. In this study, the regional characteristics of the materials used in San-ja and changes of the materials over time were examined. To this end, 123 documents on the repair of wooden architectural heritage recorded since the 1950s were reviewed. It was found that there was a difference in the San-ja material by region because of the diversity in the conditions of material supply. For instance, bamboo was the most frequently used material in Jeollanam-do province because it was readily available. However, with the development of transportation and vehicle, the regional characteristics have disappeared. As a result, the material has been unified with bamboo now. This is because bamboo is specified as a representative material in the specification or the convenience of construction is prioritized. In addition, the social and economic conditions at the time of repair had an influence on the selection of the San-ja materials.

The objective of this research is to determine overall heat transfer coefficients (K-value) of exterior wall, floor, and roof of Nakseonjae, a Korean traditional residence via field measurement of transient heat flow and temperature difference across each envelope component. Heat flow sensors and T-type thermocouple were attached on the internal and the external surface of each building component, and real-time measurement data were collected for the three consecutive summer days. The K-values determined in this research showed good agreement with other results from open literature. Peak and annual thermal loads of the traditional residence estimated by a commercial energy simulation program were compared with those for a current apartment house. The traditional house showed lower annual cooling load than that of the current building. It may caused by the fact that the traditional building has less air-tight envelopes and no fenestration passing direct solar radiation into the space.
