"Eco-friendly construction" is an emerging issue in the building industry. Main purpose of the eco-friendly construction is to sustain the health and environment of building residents and to minimize the harmful effect on their environment. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Environmental performance is to meet through using the highest grade eco-friendly materials. However, generally eco-friendly materials are more expensive than normal materials, Therefore, using eco-friendly materials at public housing project is limited to economical aspect. The purpose of this paper is development of eco-friendly material selection model considered cost efficiency. The selection of Eco-friendly finishing materials and their methods are constructed to consider environmental performance level and cost index compositively. Development of eco-friendly material selection method is economic and reasonable one when public housing is constructed.

Many researches and policies have been carried out for saving energy in buildings. However, there are a few studies of thermal characteristics of wood-based materials that have been widely used as structural materials and finishing materials in buildings. In this study, thermal bridging areas were found to investigate thermal performance of residential building using non wood-based materials and wood-based materials. And heat transfer analysis of 16 case studies according to composition of structural materials and finishing materials was conducted. Also in this experiment, Physibel Trisco was used as the heat transfer analysis simulation tool, which conforms to the calculation method of ISO 10211. Analytical modeling was also carried out according to the ISO 10211, and the boundary temperature conditions were set at room temperature $20^{\circ}C$ and outdoor temperature $-11.3^{\circ}C$ (Seoul standard) according to the energy saving design standard in South Korea. Applied structures are classified according to the cases of concrete structure with non wood-based finishing materials, concrete structure with wood-based finishing materials and wood structure. Analyzed building elements were divided into a wall, a roof, an interlayer floor and a bottom floor. As a result, it can be confirmed that the thermal bridge of the concrete structure and wood structure were caused by the geometrical and material causes. In addition, the structural thermal bridge was caused in the discontinuity of the insulation in the concrete structure. Also it was confirmed that the linear heat transfer coefficient of the wall decreases when the wood-based materials are applied to the concrete structure.

In modern days when architectural materials have grave impacts on overall design expression, materials for architecture, modern architecture into the service facility for business, education, religion, cultural assembly and residence, and evaluates each finishing material mainly used in exterior, lobbies and entrances of the building since the 1970's. When being applied social images into firstly selected materials, the scopes for material selection will be more narrowed down in more practical way. High tensity materials are suitable for public and active space and low tensity are for private and static area. This principle enables us to use architectural materials as one of the important elements which express the whole characteristics of the area.

In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. This study closely verifies the concept of tensity analyzed in preceding studies by quantifying it through experimentation and questionnaire, and suggests possible alternatives which verified concept of tensity applies into the architectural design. It was examined how architects consider the finishing materials through a questionnaire. With a questionnaire, the possibility of quantificative analysis for tensity is evaluated by SPSS program. Moreover, a questionnaire about the social image that the architectural finishing materials have was also conducted. This questionnaire results In the actual methods to apply quantificated psychological tensity and social images into the architectural design and recommends better plan to select finishing materials for each spacial function and usage, Due to the great influence of social images in design expression, the application mechanism of the tensity should follow the general and individual principles together. With the tensity figure and application of social images we can find more resonable method for material selection.

The purpose of this study is providing a systematic method of exterior, interior finish materials and color scheme for elementary school and the actual color plans of elementary schools in Busan was analyzed to support the study. As a powerful design tool, a finish materials and a color are very effective to alter the perception of a building and a view. Most of the school, a shape and a material of elevations are monotonous and uniform and it makes students are hard to attach to their schools. As a place for learning and school life, the inner space of elementary classroom needs to be considered very important. The new basic guideline for developing and planning of architectural design could be achieved by researching a current plan and a finish material in elementary school. As a result, this study will benefit in planning both the exterior and interior environments of color.

There are the relevant provisions that apply to building regulations about the Building codes, Fire Protection laws, and more Multi-using interior finish materials businesses etc. The differences between these regulations are as follows: The Building codes is defined the main use of the building according to facilities to used to set the scale by the use of the floor space, On the other hand, Fire Protection laws are the basic purpose and the act of using the architectural space(or sales) by separating object by fire. And Multiple-using Businesses Facilities consist of two regulations engaged in the kind of law and the size of the floor area. One building can not be based on operating facilities and together in Multiple use businesses Law. As such, the Buildings are applied to the Building codes, Fire Protection laws, such as Multi-using Businesses Facilities interior construction industry due to the structural differences in the position of the designer feeling a lot of difficulties and confusion. The Multi-use businesses Facilities engage in the kind of law, the size of the floor area and seating capacity. These can not be based on operating facilities, and consists of two regulations together in one building. This study is purposed to help improving the finish of the interior architecture that is related to the Building code regulations, Fire Protection laws, Multi-using Facilities interior finishing material relevant with the provisions from the law through analyze the case of developed countries, and the current Multiple use Businesses Facilities research range from the law of multiple-using facilities, interior finishing, interior architecture for supervision reasonably and compensation for the interior design. So, Result is as follows: First, interior decorations can be separated the fixed material and the moveable things. second, It should be included multi-using Business though small size business space at the basement floor. third, It should be established statute law that design and construction responsibility. forth, re-testing fire resist performance after some period. and finally, it need to mitigate regulation where be installed sprinkler.

우리나라의 교회는 점점 신도수가 늘어나면서 점차 대형화되어가고 있으며 많은 첨단 설비를 갖추고자 하는 교회도 적지 않다. 하지만, 교회설계에 있어서, 대체로 그 형태와 규모만 중요시될 뿐, 그 기능에 적합한 건축물을 짓는데 소홀해 왔던 것이 사실이다. 교회의 예배공간에서 이루어지는 음향적인 매개체는 찬양과 설교인데, 이 두가지의 물리적 특성이 다르기 때문에 교회건축에 있어 실내음향은 어려운 과제라고 할 수 있다. 즉, 성가는 긴 잔향시간과 음의 따뜻함(Warmth)과 친밀감(Intimacy)등이 중시되는 반면, 설교는 소리의 명료도, 요해도(intelligibility) 등이 중시되는 등 그 음향적인 특성이 달라, 각기 다른 음환경을 요구하기 때문에 강당이나 음악당보다 교회음향이 건축적으로 난점이 있다고 하겠다. 본 연구는 최근에 시뮬레이션을 통해 음향설계를 실시한 규모가 각기 다른 예배실의 제원과 음향성능을 조사하고 그 특성을 비교, 분석하여 일반적인 음향성능을 개선하기 위한 방안을 모색하여 교회 음향설계단계에 자료를 제공하고자 한다. 이를 위하여 예배실의 규모에 따라 5개의 교회를 선정하였으며 시뮬레이션을 통해 얻어낸 각 교회의 성가시, 설교시 실내음향인자값(SPL, RT, C80, RASTI)과 마감재료 등을 조사하고, 비교하였다. 대체로 규모가 큰 교회에서 음압레벨이 작게 나타났고, 잔향시간도 실의 체적이 클수록 크게 나타났지만 마감재료와 형태에 따라 차이를 보였다. 또, 대형교회의 음향적 결함을 보완하기 위해서는 건축의 형태, 재료는 물론, 전기음향설비의 보강이 중요하다고 하겠다.
