The purposes of this study were to make clear the present condition of the TVOC and HCHO concentration after remodeling in apartment houses and to analyze the relation of concentrated ascension and remodeling elements. The field measurements of TVOC and HCHO concentration were carried out in 4 subject apartment houses according to the Korea Test Method Standard for Indoor Air Quality. The results are as follows; the TVOC concentration after remodeling ranged from mean 0.35ppm to mean 5.08ppm and increased of 0.35$^{\sim}$5.08ppm. The concentration of 3 subjects exceeded the Indoor Air Quality Management standard for the newly-built apartment houses (0.7ppm). The HCHO concentration after remodeling ranged from mean 0.13ppm to mean 0.43ppm and increased of 0.06$^{\sim}$0.26ppm. The concentration of 2 subjects exceeded the Standard (0.16ppm). As results of analysis on the relation of concentrated ascension and remodeling elements, the amount and the types of finishing materials and adhesives affected concentrated ascension. Also, production method for installed or purchased furniture had certain effect on the TVOC and HCHO concentration ascension.

In responding to the recent framework convention on climate change, and the rise of the need for energy efficient buildings, such as Zero Energy Buildings (ZEB), domestic insulation standards and energy conservation regulations are being reinforced, to prevent heat loss. Accordingly, the Ministry of Land, Infrastructure and Transport have made amendments in Chapter 21 "Enforcement regulations for building facilities standards etc.", and Chapter 22 "Energy conservation standard", to reflect these changes. To effectively implement these regulations, it is required to propose air-tightness test methods, and establish air-tightness standards, based on the air leakage characteristics of domestic apartment housings. This research has been done primarily to collect basic technical data, to provide guidance for the establishment of domestic air-tightness standards for new apartment housing, through studying air-tightness test methods, field measurement on air-tightness of new apartment housings, and air leakage characteristics of major developed countries.

The apartments of South Korea has developed enormously from 1960's to the present. Nevertheless, People have not paid much attention to the exterior colors used in the apartments. For this reason, this study tries to understand the differences of the colors between each brands and areas based on the newly-built apartments in Jeonju and Gunsan, and this focuses on the colors used in the main buildings, public facilities, playgrounds, and the main entrances. According to the research, although six-cases all showed that YR was higher than any other color patterns, but there were differences from both the brands and the areas. Both the colors and the materials, as distinguished by the brands, were more diverse in the apartments by the small or medium businesses than in those by the big businesses. Moreover, when the identical brands were observed in Jeonju and Gunsan, the differences between the areas was more recognizable than the differences between the brands. Both the colors and the materials, as distinguished by the areas, had more varieties in Gunsan than in Jeonju. It was because Gunsan had many diversities in natural, historical or social backgrounds, as compared to Jeonju. Unlike other studies, this study researched public facilities as well as the main buildings so that it was possible to perceive the harmony of the colors in the apartment complex; however, the cases used in this study were limited numerically.

Recently, concentration of fine and ultra-fine particulate matter(PM) has been increased in KOREA. The increase of PM in KOREA is due to increase of domestic industries and yellow dust from china. PM is known to cause diseases such as dyspnoea, asthma, arrhythmia. Since PM is harmful to human, KOREA Ministry of Environment(ME) warns people to stay indoors when the outdoor PM concentration is high. However, prior studies has shown that indoor PM concentration can be relatively high when outdoor PM concentration is high due to infiltration of PM into buildings though leakage areas. In this study, airtightness, indoor and outdoor pressure difference and PM 2.5 & 10 concentration were measured in an apartment complex to observe PM infiltrating into building. Field measurement was conducted in newly-built apartment buildings to avoid the influence of indoor PM which can be generated by residents. The airtightness test was conducted to identify the leakage areas of the apartment, such as electric outlets and supply/exhaust diffusers. The airtightness test result showed that the air leakage area of the building was dominant in buildings envelop. According to indoor and outdoor pressure difference measurement result and PM concentration measurement result, it can be concluded that outdoor PM can infiltrate into indoor by leakage areas when wind is blown toward the apartment. As a result, pressure difference formed by the external weather condition and architectural characteristics such as the airtightness in building can influence PM to infiltrate into buildings. In further studies, I/O ratio, stack-effect, infiltration and penetration factor will be considered.

Recently, newly built apartments in Korea are provided various home automation (HA) systems based on information technology(IT) for residents' safer, healthier and more convenient living. However, the residents in these digital apartments are often not able to use the home automation systems effectively because of lack of their IT knowledge, attitude, or education. However, there are few researches have been done to find out the HA systems' real problems with regard to residents' aspects who use those systems everyday. The purpose of this study was to find out residents' current uses, satisfaction level and existing problems of HA systems by residents' POE. The findings of this study will give useful information to digital home construction companies to provide user-friendly digital home services for increasing users' satisfaction. One distinctive apartment equipped with home automation systems located in Seoul was selected for in-depth personal interview. The researcher developed a survey instrument and collected the data from 58 residents in January, 2007 who had been living there for more than a year. The results of the study found that critical problems were existed in several systems and they caused a lot of dissatisfaction from the residents. Also, some residents do not use several systems although they need to use them due to the burden of maintenance fee. Further detail findings and suggestions of this study were discussed.
