Remodeling for an aged building is emerging as a potential alternative towards the future of the building industry. It is a more effective method than the new construction in environmental friendly view. Most of remodeling were aimed at the improvement of the function of the deteriorated finishing materials. But, at the early stage of remodeling process, energy performance of a building can be improved by adopting passive design solutions such as daylighting and natural ventilation. The purpose of this study is to explain the passive design strategy in remodeling process and to suggest a application of LT method. LT method is an energy-design tool which responds to parameters available early in design development. It provides an output of annual primary energy for lighting, heating, cooling and ventilation in non-domestic buildings. LT method basically uses the concept of passive zone and non-passive zones and should be used to evaluate the energy performance of a number of options and to make comparisons. In this paper, the process of LT method is introduced and investigated an applicability in our office building.

Recently, the educational facilities were 45% among total damaged facilities from the Po-Hang earthquake. Consequently, the seismic reinforcement of existing educational facilities were ended up attracting people's interesting. However, research is insufficient to consider that how far technology has been developed. Therefore, the purpose of this study is to investigate the level of domestic guideline research by comparing to foreign guidelines in regard to seismic reinforcement methods applicable to existing educational facilities. To achieve the objective, first, the current status of seismic reinforcement projects in domestic educational facilities was analyzed. Second, the domestic and foreign seismic reinforcement methods guidelines for structural, non-structural was compared. Third, the improvement directions for future guidelines were suggested. As a results, the improvement directions of domestic seismic reinforcement methods guidelines were proposed. First, the structural seismic reinforcement strategy needs to be segmented. Second, it is necessary to analyze about non-structural guidelines based on additional cases. In the future, this study can be used as a basic material for developing seismic reinforcement methods guidelines in domestic existing educational facilities.

국내 리모델링 시장은 초창기로서 비주택 부문을 중심으로 성장하고 있으며, 일반건축물의 리모델링 사업을 수행하는데 무리가 없으나 공동주택 리모델링 사업을 추진해 가는데는 재건축의 수익성에 익숙한 주민의식, 업계의 사업수행 경험 및 노하우 부족, 정책실행의지 및 구체적 실행방안 부족 등이 어려움이 되고 있다. 리모델링 사업환경을 개선하기 위해서는 리모델링 수요자측의 인식전환, 정부의 강력한 경제적 인센티브 제도 제공, 신축위주의 파라다임에서 건물의 라이프사이클을 괴려한 건설경영 파라다임으로의 전환, 기존건물의 상황을 충분히 활용하는 공사방안 도출 및 활용, 리모델링 관련 산업 인프라 구축이 필요하다.

Apartment design in residential Area is restricted by building distance limit code. Building distance limit decreases gradually to the 0.8H(height), and residential area has 250% site area ratio by building code, so site using has become efficient. In this study, examine the relationship between present building distance limit and right of daylighting environment by computer simulation. As well, high-rise residential officetel and multipurpose residential building becomes increase in commercial non-residential area. In the domestic, residential type multipurpose building made at the business area or central business area has 400∼800% site area ratio by building code. However, at a dweller's point of view, there are much lacks of environmental consideration to provide suitable daylighting environment. And, POE: Post Occupancy Evaluation is not completed yet. In this study, however, progress architectural environment prediction, basis by right of daylighting, and examine the possibility of daylighting by architectural distance limit code in residental area and by high-rise, high-density residential building in non-residental downtown area.

Exterior wall molding, which is widely applied as a design element of the exterior wall of domestic apartment, should be applied as a nonflammable or semi-nonflammable material grade according to the rules on standards for evacuation/fire protection structures of buildings. For this reason, stone and AL sheet are mainly used, but stone is expensive and design autonomy is low. Inorganic reinforced CLC nonflammable molding was applied to the exterior wall of the building through tests of nonflammable performance, noise reduction, and installation stability.

Designers and builders are omitting structural design and relying on workers' experience, due to the lack of awareness of the importance of scaffolding in domestic construction sites, and there is a high probability of collapsing accidents such as inappropriate wall joint installation and non-compliance with work procedures. Therefore, risk factors were analyzed in detail and major risk factors were derived from opinions of site managers and scaffolding experts in this study.

Installation and usage methods are currently different between China and Korea for the same rubber asphalt waterproofing sealant. Quality verification is not properly carried out in this situation, so it is necessary to secure reliability in order to export domestic materials to China. In this study, rubber asphalt waterproofing sealant used as injection-type leakage repair material was tested in accordance to adhesion strength quality test method outlined in the JC/T2428 Chinese Industrial Standard to confirm the basic performance is compliant or not.

Recently, it is being studied on the high strength concrete in many laboratories and being applied to the construction field actually. But non-destruction testing equation that to be proposed about normal strength concrete in Japan has been using because the systematic study results for the estimation of compressive strength of high strength concrete do nit exist. So it is essential to suggest the non-destruction testing equation for the estimation of compressive strength of high strength concrete. This is an experimental study to analyze and investigate the non-destruction testing equation for the estimation of compressive strength of high strength concrete. The results are as follows; The relation between rebound number, pulse velocity and compressive strength of high strength concrete have lower coefficient than combined method of rebound number and pulse velocity. Also new non-destructive testing equation for the estimation on the compressive strength of high strength concrete was suggested in this study, and it is considered that these equations have possibility to be applied in domestic construction field.

Recently, ESG bond issuance has been gradually spreading to banks and non-financial private companies in Korea. However, the Korean ESG bond market is still in its infancy in terms of size, diversity and investor base compared to the global ESG bond market. In other words, ESG bonds are rapidly forming in the global market, but are still in the formation stage in the domestic market, and various policy and practical measures such as system, incentives, and infrastructure are needed to activate them. In this paper, we examine the domestic and international status of ESG bonds in relation to responsible investment. In addition, this paper explores specific measures to revitalize the domestic ESG bond market in four aspects: establishing ESG bond standards, procedures and regulations, increasing ESG bond investment demand, increasing ESG bond issuance, building market infrastructure and market efforts. This study is expected to contribute to the development of the domestic ESG bond market and responsible investment.
