Recently, much attention has been paid to the problem such as sick building syndrome, which caused by the indoor air pollutant. Volatile Organic Compounds $(VOC_s)$ and formaldehyde have been considered as one of the main reason that causes indoor air pollutant. This study is for introducing and designing thermal performance of super energy saving building by conducting $VOC_s$ and formaldehyde concentration in the 3Liter house. The results of the measurement for 10 months showed that $VOC_s$ and formaldehyde decreased until the guideline concentration. It took about 7 months, and it appeared right after new construction. However, their levels were showed higher concentration in comparison with the ordinary residential houses (apartment house). The main difference of between newly built 3Liter house and ordinary apartment is their air changes, which are 0.67/h for 3Liter house and 4.0/h for the apartment.

Recently, IAQ(Indoor Air Quality) is regarded as one of the most important environment factors as well as thermal and acoustic comfort. A lot of paints, adhesives and chemical materials which are known to emit gaseous chemical pollutants are being used in building. These building materials are potential sources of indoor chemical substances. Bake-out has been as one of mitigation methods for the chemical substance contained in the building material. However, an examination about the effect of the bake-out is not sufficient. So, this study was conducted 1) to establish the bake-out procedure and evaluation method used with new apartment in winter, 2) to determine the effectiveness of the bake-out on formaldehyde and VOCs reduction. From our results, in winter, it was confirmed that the emission rates of formaldehyde and VOCs decreased after bake-out in a temperature of 32∼33℃ for the period of 72hours, and next to put in operation 1days(about 8hours) of cross ventilation.

The purpose of this study is to find out characteristics on perception of indoor air environment, and derive main influential factors for indoor air quality recognition based on apartment resident's responses. Questionnaire survey for residents responses was used for this study. The findings from analysis were as follows: The main factor that influences to cognition and anxiety degree about Sick House Syndrome were related to their children, mainly regarding the age and the time of staying at home. The residents showed high level of awareness and anxiety for Sick House Syndrome, but they are indifferent or have no awareness on construction company's implementation plan and its detailed contents to prevent Sick House Syndrome. Consequently, construction companies need to share information of plan for improving Indoor Air Quality and its Contents with residents more actively to reduce the degree of anxiety on the subject, and residents need active effort in collecting the information on Sick House Syndrome.

The objective of this study is to analyze the Characteristics of formaldehyde concentration according to the type of temperature control, to suggest the control methods to decrease formaldehyde emission in indoor conditions. This study was measured temperature, relative humidity(RH), formaldehyde that a single point in 50 household and plural point as time passes in 3 household. And control condition of a room, there are distinct the section of a artificial control and a self-regulating control. Formaldehyde was analyzed by HPLC. The results of this study are as follows; In the section of a artificial temperature control, formaldehyde concentration showed the crucial emission point which extremely increased formaldehyde concentration at 25℃, that the absolutely independence temperature over 25℃. And, in the section of a self-regulating temperature control, formaldehyde concentration have the crucial emission point at 25℃ too, showed the independence on temperature at over 25℃, selectively independence at less than 25℃, and generally dependence on RH in the typical range 20-70% for ordinary life.

The purpose of this study is to evaluate the level of illumination and the process of applicability in its aspects of the legal practice. An object of investigation was used with the data which were obtained by the differences in buildings completed for apartment underground parking garage since the late 1990s. The sample size was that of 9 apartment houses in Ulsan. The results of this study were as follows; 1) Overall, the level of illuminance is shown to be kept below the criteria of the regulation. 2) In order to satisfy the criteria suggested of the law, subjects of the investigation don"t have an active aspect to reflect the objectives and significance for changing standards. But are merely obsessed with meeting minimum requirements for illumination installation. 3) In the current situation where only minimum illumination is regulated, a problem occurs because improvement of uniformity ratio has not been made. So better regulations are needed to alleviate the problem of illumination that is need to adopt the regulations in the average illumination.

Today, many countries are making efforts to advance eco-friendly technologies and new energy enterprises. Our government has also shown much interest in policies related to eco-friendliness, green growth, energy conservation, and CO₂ reduction. Recently, more attention has been given to LED lighting, with low-carbon, green energy in mind, and there has been a trend in dimming control systems for energy conservation. The purpose of this research is to examine the changes and longevity of automatic lighting control systems in apartment underground garages through an investigation of regulations and documentation related to garage lighting systems. As well, through the investigation of underground garage lighting environments in 8 apartment houses, it will provide basic data regarding luminance levels and uniformity. The results of this study are as follows. 1) Currently, the government approach to reducing lighting energy is through laws and policies which require a changeover to automatic lighting control systems in apartment underground garages. These are expected to continually increase. 2) It is necessary to secure a standard for items such as measurement of lighting, luminance level, methods of control on applying automatic lighting control system. As well, work is needed to standardize a minimum luminance level and level of uniformity. 3) Currently, there is a need to improve the standard of illuminance. For example, there needs to be regulations set for the uniformity of lighting in all driving aisles, parking areas, entries & exits, as well as pedestrian access areas. Besides these, there must be separate daytime and nighttime lighting standards for vehicle exits and entrances.
