The purpose of this study is to validate the environmental performance of the 'eco-friendly lightweight form' in the construction process. Unlike existing euro form and aluminum form, the proposed form does not require form oil during the process of concrete casting and is lightweight because it is made of engineering plastic. Therefore, eco-friendly lightweight form will reduce the $CO_2$ emissions in the construction process. To verify the hypothesis, the study compared existing forms and eco-friendly light weight form's $CO_2$ emissions in each stage in construction process when using 1,000 forms and 100 times from the LCI(Life Cycle Inventory) data. The total $CO_2$ emissions of the eco-friendly light weight form were 30,487kg $CO_2$, which equated to about 58% and 20% less emissions than the euroform and aluminum form. The result of the study verified that the eco-friendly lightweight form was effectively reduced $CO_2$ emission in the construction process.

The improvements of G-SEED standards was studies in this research by comparing the composition, rating scores, and standards, including categories, issues and criteria of BREEAM in the UK. In this research, it was found that both certification systems had very similar composition and rating system, however, there was slight difference in the points of emphasizing the standards due to the differences in social awareness of green buildings in each country. As a result of the detailed comparison of both standards, in addition, it was found that almost half of criteria had different evaluation approaches such as evaluation methods and scopes between both standards even though they had same evaluation objectives; some of the differences were due to the social or cultural differences between the countries, and the others were not. Through the research, we were able to derive some criteria that need for improvements of G-SEED considering the domestic conditions in Korea.

This study proposed vision artificial intelligence-based automated supervision technology for external insulation and finishing system, and basic research was conducted for it. The automated supervision technology proposed in this study consists of the object detection model (YOLOv5) and the part that derives necessary information based on the object detection result and then determines whether the external insulation-related adhesion regulations are complied with. As a result of a test, the judgement accuracy of the proposed model showed about 70%. The results of this study are expected to contribute to securing the external insulation quality and further contributing to the realization of energy-saving eco-friendly buildings. As further research, it is necessary to develop a technology that can improve the accuracy of the object detection model by supplementing the number of data for model training and determine additional related regulations such as the adhesive area ratio.

The proportion of old buildings over 30 years old increased from 29.0% in 2005 to 37.8% in 2019. These old buildings were created during the absence of building-related safety standards such as fire safety performance. In the process of use, illegal changes and extensions were made, making them more vulnerable to safety. In the 1st Basic Plan for Fire Safety Policy, among the 12-Key Tasks, one is to ensure the safety of residential living spaces. Fire safety investigations are being conducted to prevent large-scale disasters such as multi-use buildings, but no investigation has been conducted at the regional district level where small-scale old buildings are concentrated. Therefore, in order to derive fire risk factors in the old building district where old buildings are concentrated, the composition characteristics of the buildings were first analyzed.

The Golden Ratio has played a significant role in many parts of geometry, architecture, music, art, and philosophy. This number has been the subject of numerous experiments in psychology. It also appears in the newer domains of technology and fractals, In this paper, we investigate and analyze the golden ratio which appears in art, music, and architecture.

I discuss the preliminary version of an investigative software, GSE, - Genetic 3D Surface Explorer, in which genetic operations interact with AutoCAD to generate novel 3D Forms for the Architect. GSE allows us to comment on design issues concerning computer aided design tools based on evolutionary algorithms.

In the budgeting guidelines, there are rules for calculating design fee and direct costs. However, only the design fee is calculated excluding the direct cost, which causes the cost to be insufficient. Therefore, this study is designed to analyze representative cases where direct costs are insufficient, draw out problems, and propose a way to improve design fees.

The pupose of thesis is to analyze the architectural characteristics of Mies's Barcelona Pavilion. I analyzed the site, space, form, structure, aesthetic elements, compared it with two other buildings by him, and studied the evaluation and interpretation about the building. I cocluded that all of the modern architectural elements were fused in the crucible of Mies's imagination to produce an original work of art.

Interest in indoor air quality is increasing day by day due to various reasons such as industrial development. Because redmud, an industrial subsidiary, contains titanium dioxide, this study evaluated self-consolidation performance with Slump Flow Test, J-Ring Test, and L-Box Test by mixing redmud in a mixture of ultra-high performance concrete, and sought the optimal combination with high flowability. In addition, the UHPC mixing experiment with photocatalyst was conducted, and the photocatalyst was replaced by the weight ratio of cement and the redmud by the weight ratio of fine aggregate and mixed with the concrete mixture.

The number of share houses has increased in Korea, and social recognition of this type of housing is also growing. In order to review current conditions and housing systems for share houses, an analysis of rooming house, a type of share house that is built overseas, was carried out. This study focused on studying rooming houses of Canada. Residents occupy in rooms and share common spaces with other tenants in rooming houses. The purpose of this research is to study planning guidelines, systems, operation management of rooming houses and the process and role of public and citizen participation. Based on characteristics of planning guidelines and operation management for rooming houses, implications which can be used for setting institutional and planning foundations for share houses in Korea have been presented through this research.
