  • Recently, indoor air pollution has been seriously apprehended, and became a striking issue, due to the airtightness of buildings or the misuse of building materials. Especially, SHS(Sick House Syndrome) and MCS(Multi Chemical Sensitivity) which can have bad influences on the resident in an existing apartment house as well as newly constructed apartment house start to attract public attention. The emission rates of VOCs is sensitively affected by the indoor/outdoor condition, construction materials, construction method, and character of ventilation facilities. Therefore, in this study, by measuring the indoor air pollution substance of the existing apartment house, the problem over this tends to be grasped and it is going to secure an improvement methods.

  • The recent rising living standards, environment-friendly, well-being and health aspects of life in the basic gratification, as well as the desire for a pleasant environment emotionally environmentally friendly way of external space or industrial interest in the indoor environment, the manifestation. In particular, the biggest problem of the indoor environment has been emerged as a Sick House Syndrome indoor space that is provided to the building materials, and the impact on the domestic and the indoor environment, and clean the house in a health standards are specified as laws. The performance rating and the various materials to create environmentally-friendly standards for building materials. The more detail, Porous clay material, toxic substances released by applying the high humidity and the water itself, and to absorb the moisture, if the emissions, without a separate device, to maintain a comfortable indoor environment and at the same time, one of the causes of Sick House Syndrome breaking down harmful substances to absorb a comfortable indoor environment to maintain an environmentally-friendly building interior material studies. It is aimed at the development to multi-functional high performance eco-friendly construction materials, rather than through one feature performance, identify key features for national and international eco-friendly building materials can exert Water Vapour Adsorption raw, decomposed materials for the application and selection.

  • Recently, due to the airtightness of buildings or the misuse of building materials, we have been witness SHS (Sick House Syndrome) which can have bad influences on the resident in an existing apartment house as well as newly constructed apartment house start to attract public attention. As a result of this situation, we went to restrict the TVOC (Total Volatile Organic Compound) and formaldehyde. But these guidelines concentrated on only TVOC although TVOC are consist of many individual VOC. Therefore, in this study, we will look about concentration change of VOCs (Volatile Organic Compounds) by using Mock-up test. As result of test, the concentration of four individual VOC (Benzene, Toluene, Ethylbenzene, Styrene) showed quitely low level after 7 days. On the other hand the concentration of Xylene and formaldehyde showed low level after 14 days.

  • In recent years, living space of modern society have vared, and new methods to build have been introduced using new building materials and interior finishing materials as the life level is enhanced. But these kinds of materials release some harmful substances to people. The most of people living in new apartment have headache and dizziness, and feel sick of the stomach, sleepiness, eye stimulus, concentration decrease and allergies. That called 'sick house syndrome'is becoming new society problem. The purpose of this study is to investigate the kinds and various problems of the interior finishing materials and to pursue improvement of living place and pleasant interior surroundings.

  • In this study, activated carbon fibers (ACFs) were treated by oxy-fluorination to improve the adsorption property of benzene gas, one of the gases causing sick house syndrome. Surface properties and pore characteristics of oxyfluorinated activated carbon fibers were confirmed by X-ray photoelectron Spectroscopy (XPS) and Brunauer-Emmett-Teller (BET), and adsorption properties of benzene gas were evaluated by gas chromatography (GC). As a result of XPS data, it was confirmed that the fluorine functional groups on activated carbon fibers surface increased with increasing the fluorine partial pressure. The specific surface area of all samples decreased after the oxyfluorination treatment, but the micropore volume ratio increased when the fluorine partial pressure was at 0.1 bar. The oxyfluorinated activated carbon fibers adsorbed 100 ppm benzene gas for an 11 h, it was found that the adsorption efficiency of benzene gas was improved about twice as much as that of untreated ones.

  • The recent trends of high-density and high-rise in apartment housing have caused the problems of decrease in ventilation rates and increase of indoor pollutant contaminants. SHS(Sick House Syndrome) has now become a major issue and threats the health of residents. To solve these indoor air problems, increase in ventilation rate is considered as one of the most efficient approach. Thus, the recent housing development is pursuing improvement in the site design and the layout of apartment building blocks to promote natural ventilation is now investigated as one of the fundamental solutions. This study was focused on the air flow characteristics of outdoor environment in an apartment complex to keep the pollutants out of the site. Age of air and pressure difference have been used as indices of the outdoor air quality. Four different types of apartment building layouts have been analyzed by CFD simulation. This study again selected a real apartment housing complex as a case study model. By analyzing the pressure differences between the front and rear of an apartment building block, the ventilation performance in each individual unit was evaluated, and its impact on ventilation performance is investigated by analyzing the stagnant air around the apartment building blocks. During this process, existing patterns of apartment housing layout have been evaluated, and the most appropriate site layout has been chosen to analyze the outdoor airflow patterns. Based on the analysis of airflow patterns of site layout, the possibilities of improving ventilation performance of an individual apartment housing is proposed.

  • Recently, much attention has been paid to the problem such as sick building syndrome, which caused by the air pollutant indoor. In addition, Volatile Organic Compounds(VOCs) has been paid attention to as one of the main reason that causes air pollutant indoor, and the exposure of VOCs indoor is recognizes as an important factor which have an effect on the health of resident. In this study, measuring of VOCs in newly houses, and the results are as follows; 1)TVOC(Total Volatile Organic Compounds) indoor is detected high concentration(11314$\mu\textrm{g}$/㎤). 2)There are detected acetaldehyde, methylenechloride, benzene, trichloroethylene and styrene that have to take precaution against human carcinogenicity

  • In a traditional society, building materials were developed fulfilling the requirements of conveniences and functionalities such as safety, construction work, durability and economical efficiency. However, as the concern about environmental or users' health issues has been elevated recently, research and development about eco-friendly material are alto vigorously promoted further In addition, thanks to the steady growth of domestic industry, the amount of discharged industrial by-product is getting increasing. However, its recycling rate remain at low level as most industrial by-products are filled up in the land, which worsen the environmental pollution. Zeolite powder is cement admixture and is expected to have constraining effect of factors causing symptoms of inhabitants in a new house and alleviates the amount of discharged harmful elements emitted from hardened cement.
