  • To many developing countries like China, the practical way to constant development of city construction is low consuming. The basic methods of low-cunsuming landscape construction: 1) Low building consumption: Decreasing construction quantity. Using low-costing material. Designing low-consuming landscape. Reusing of building material. 2) Low energy consumption: Decreasing water consumption. Consuming and enrichment of earth fertilizer. Decreasing electrical consumption. 3) Low maintenance: Adapting natural material. Using local plants. Special design to decrease maintaining. Because of many reasons, China has not yet adapting Low-consuming Landscape Construction.

  • To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

  • After the new house symptoms recently, room environment pollution problem of building syndrome and so on is becoming research about ways to solve this being risen. Is taking advantage of nature data by building materials by one of this way, but Friendly Environmental performance examination for structure material is insufficient misgovernment being real condition that put emphasis in ability as most embellishment and in finish. Environmental examination is insufficient misgovernment on factor itself as structure material. Also, being real condition that radon that is responsible for lung cancer occurrence next to smoke in building materials such as concrete and so on is happened, the danger is reported much through mass communications and research paper etc. Therefore, this research measured radon release amount and the carbon dioxide adsorption rate for physical special quality measuring and Friendly Environment Efficiency that follow to 'KS F 4004 Concrete bricks' regulation after manufacture Concrete Bricks utilizing charcoal that is nature material by sand. This study finding carbon dioxide density appeared and displayed effect that charcoal Controls radon release that happen in Concrete Bricks to maximum 74% that decrease to best 95% though decreased the charcoal addition rate increases.

  • Formerly, it was called a tent and now, it is called membrane structure. If saying a tent, it imagines the tent of Bedouin, Mongolia and North American Indian. It became clear from the excavated wall painting that have been covered with the retractable roof of the canvas on the auditorium at the amphitheater in Pompeii and became a topic. These tents were made of the animal skins or fabric woven with the flax plants, and these tents are still used. However, if saying membrane material at present, it says the one to have applied a coating resin to the textile. Because the base fabric of membrane material is a woven fabric, the relation between the stress and the strain is different to the direction of the weaving thread. Moreover, the tensile force must always occur in the membrane surface. From these reasons, because the membrane structure corresponds to the particular building material and the construction method about the Building Standard Law, it must be examined specially that the membrane structural building have the same or any more safety as the provisions which was set to the Building Standard Law. Therefore, the technical standards about the membrane structural building became indispensable. In the paper, the kinds of the membrane materials, which are used for the membrane structural buildings, and technical standards process of the creating for the membrane structure buildings are introduced. Lastly, some of the soccer stadiums for 2002 FIFA World Cup KOREA/JAPAN which be covered with the roof of the membrane structures are presented.

  • The current building energy efficiency rating certification regulation on apartment houses evaluates only the saving rate of energy consumed during operation, i.e. use, of a building, but doesn't consider the energy consumptions and environmental load($CO_2$) emissions occurring during the whole lifetime of a building. So this study calculated the energy consumptions and environmental load emissions occurring during the whole lifetime of a building, selected reference schemes and alternative items by design variables to present a design draft considering energy efficiency and environmental performance, and evaluated the total cost by combining and calculating its direct cost(material and heating cost) and indirect cost(environmental cost), for an existing apartment house as an evaluation object. As a result of analysis, the change of heating cost by alternative items of design variables showed a 4~8% change rate compared to the reference scheme, and the material cost of design variable 7 showed a maximum 4.4 times change rate in the alternative plan 6 compared to the reference scheme. The environmental cost showed a similar change rate to the material cost change rate in general, but showed a similar environmental cost change rate to the heating cost change rate in case of design variables 4-1, 4-2, 7.

  • In case of Korea, The Large-scale fire is consistently being such as 2015 Uijeongbu Fire, 2017 Jecheon Fire, 2018 Sejong Hospital Fire. Such a fire has a problem that the fire is spreading upper due to external flame spread. As a countermeasure the fire safety, the study about axial temperature prediction of external flame spread is consistently doing. But in korea, Vertical spandrel is specified as 40cm, and improvement is urgently needed. In this study, a repair material was selected to prevent the fire from spreading to a building where a flammable exterior material was installed and then pilot construction was carried out. Also, fire safety measures for buildings constructed with flammable exterior materials were examined.

  • According to the increases the standard of living of the people, requirements for building environments are also being diversified. The fungus that occurred the building is not good the health of occupants as well as undermine the value of the building. However, chemical antimicrobial agent contain ingredients harmful to human body and it has an impact on indoor air quality. Therefore, the use of natural antimicrobial material is strongly required. In this study, the fungal reproductive inhibit capacity was evaluated by using mortars with natural antimicrobial material.

  • The purpose of this study presents in Relations between cracks in self-leveling material and quality of floor groundwork surface are experimentally examined. As the first stage, the experiment to observe cracks in self-leveling material constructed on floor groundwork made from various kinds of concrete was carried. As a result, following basic findings were obtained. First, observation of cracks should be continued until an increase in width of cracks stop, without constructing any finishing material. Second, degree of cracks may be indicated quantitatively by the product of length and width. Finally, Cracks and separation is not be influenced by specimen size. Based on these findings, the method of predicting cracks by evaluating surface layer quality of floor groundwork will be established.
