土壁の工法のひとつである版築は、製造エネルギーが他素材に比べて格段に低いこと、単純な工法なため、だれにでもつくることができること、などの理由から、これからの建物に活用すべき素材として注目されている。本稿では、版築における建築デザインの実践的試みによる、その一般化について、デザインと工法の視点から論ずるものである。 版築の施工性、設計上の留意点を知るため、2001 年5 月から、2002 年3 月にかけて４畳半程度の版築構造の実験棟「版築造実験居室」(2002)（図2）を計画、セルフビルドによる建設をおこなった。このことで版築のテストピースの圧縮強度、建設にかかる日数、人数、施工費、さらにはセルフビルドで版築をつくることのメリットとデメリットについて検討した。 2004 ～ 2007 年にかけて、本研究で得られた一連の知見を基に、版築を用いた建築作品「H 邸」(2004)、「清水ヶ丘の家」(2005)、「セトレマリーナびわ湖」(2014)、ほか17 の事例が実施され、版築の一般化と普及に繋がった。

The purpose of this study is to obtain basic data on the environmental performance of the rammed earth wall. The test shelters composed of three rammed earth walls were constructed on the campus of Maebashi Institute of Technology. Field measurements for the environmental performance of the rammed earth wall were carried out in the test shelters. This paper describes the results of temperature distribution in the rammed earth wall, indoor temperature and humidity, and the transition from initial moisture content just after construction.

Architects encounter a variety of limitations in the processes of design development and construction. From safety concerns to economic challenges, the presence of such limitations is a reflection of standards expected in professional practice that at times restrict design possibilities. However, some architects use these circumstances to their advantage, and in doing so, continuously redefine design conventions. In this research, we will study the design thinking that allows designers to subvert disadvantageous conditions for pioneering, unorthodox outcomes.

 Architects design buildings in consideration of constraints such as law, owner’s request, relationship with neighbors and their endurances. Compared with buildings, installations have less constraints and are characterized by space expression with high degree of freedom and carefully selected elements. Therefore, principles such as the features of the element and the mechanism of composition appear prominently on works. In this research, the objective is to reveal how architects perceives and realizes principles when architects perform creative activities by analyzing the text description on the installation works, which prominently expresses the principle caught by the architect.

 The flow of this research is as below:

 1. Subject of this research is 931 samples from the text description on the installation works produced by architects that refer to original creation for a principle focused by the architect in architectural magazine “Shinkenchiku” and Italian architecture and design magazine “domus”.

 2. Extract the sentences that contain words: Medium of Principle, Disposition of Principle and Action of Principle. Medium of Principle is the word described as element having the principle focused on by the architect. Disposition of Principle is the word described as role and state inherent in the Medium of Principle. Action of Principle is the word described as motion and behavior of the Medium of Principle.

 3. Analyze and consider correspondence relationships between Medium of Principle and Disposition of Principle, and Medium of Principle and Action of Principle.

 4. Based on the tendencies of correspondence analysis, frameworks of semantic contents of the principles are derived. By using them to make a matrix to identify aspects of principle of creation and categorize them into types to provide insights and draw conclusions.

 Through the investigation of the matrix between Medium of Principle, Disposition of Principle and Action of Principle, 24 typical aspects of principle of creation in text description on installations were derived.

 From these, the architect set the purpose of the installations for the three stages of his own thought, creation of space and experience of space, and found the possibility of development of creation.

 As a way of utilizing the principle, the architect finds the aspects of works by principle such as work by the principle itself and realization of latent principle. In addition, the architect finds aspects of the principle born by the works such as the principles born as a result and the principles through the construction process. The architect utilized the value of the found principle from these two aspects.

 From the 24 typical aspects obtained, how the principles relate to architectural creation is examined. It reveals groups of semantic contents with the themes of unique concepts in architecture that could exist behind and around the 24 typical aspects. As a result, six themes as the principle of building creation were found; artificiality and nature, surrounding environment, existence of building, strength, construction, human emotions. Therefore, we can say that there exists the correlation between architectural thought and method to materialize the principle. This is thought to be an important guideline for future creative activities by architects.

 This report aims to illustrate how Japanese architects extrapolated a design theme from roof garden model through analyzing text and actual composition of contemporary Japanese houses with such model as it appeared in architectural publications. Initially, two aspects of the roof garden concept were extracted from explanatory text by architect themselves, and each scheme was then subjected to a “KJ-method” analysis (originated by KAWAKITA Jiro); one is the architect's intention in adopting roof garden, the other is the architect's distinct view of the spatial character on roof garden. Secondly, the actual composition of each house was assessed with regard to vertical and horizontal positioning of the roof garden. Finally, the mediation between each architect's thinking and the final composition has been plotted in terms of this dual classification.
