The concepts of interior design work have set forward an aesthetic and functional proposition to be answered by those who design spaces. The available range of suitable materials for interior use appears to be almost inexhaustible in this day and age. Now a day, relatively new fields of study on environmental-friendly interior examine humans'innate affinity for health and explore its implications for architecture and the built environment. A growing field of research suggests that spaces' relationship to aesthetics and environment can either help or hinder their occupants' health and wellness, productivity, and even their creativity. This paper presents several examples of already built apartment houses in practice, and discusses the demand of users of the spaces for health and sustainable environment, deepening the relationship between newly-constructed spaces and the remodeled ones. The considerations to some new and contemporary materials from the aspect of healthy indoor architecture design are presented in this paper. Designers need to rethink the conventional and high-tech interior environment in apartment houses with respect to perceived air quality, material emissions, and odors. The future of interior design is oriented on light shapeable materials which are able to create a unique memorable atmosphere. The primary assignment in accepting recent materials and proceedings is our responsibility to creating proposals, that are mainly safe, hygienic and environmentally proper.

Because of the airtightness of building, misuse of building materials and abuse of furniture, indoor air pollution problems have been increasingly concerned especially with apartment buildings. To improve the IAQ(Indoor Air Quality) in apartment building, this study was aimed at analyzing the factor of interior building material and furniture and calculating the ventilation rate of living room and bed room according to the surface area of interior building material and furniture in terms of VOCs(Volatile Organic Compounds) and HCHO(Formaldehyde). The results of this study are as follows; 1) In the concerned rooms, the living room has less pollution emission rate L(surface area/volume) than that of the bed room but, the living room needs more ventilation rate than that of the bed room because of built-in furniture in terms of VOCs and HCHO. 2) Built-in interior furniture is very important factor in IAQ problems of apartment building, but until now there is no provision about the built-in furniture, so that the provision must be regulated to control the IAQ. 3) To control the IAQ problem, the effective ventilation plans must be established according to the required ventilation rate by means of natural or mechanical ventilation method.

The South Korean Ministry of the Environment has revised the laws relating to the management of interior air quality for multiple use facilities, and recommends maintaining carbon dioxide ($CO_2$) concentration in passenger vehicles below 1000 ppm during operation in urban areas of large cities. However, the interior $CO_2$ concentration of passenger vehicles can rapidly increase and exceed 5000 ppm within 30 min, as observed when two passengers are traveling in urban areas of the South Korean city of Jeonju with the air conditioner blower turned off and the actuator mode set to internal circulation mode. With four passengers, $CO_2$ concentration can reach up to 6000 ppm within 10 min. To counter this, when the actuator is set to external mode, $CO_2$ concentration can be maintained below 1000 ppm, even after a long period of running time. As part of the air conditioning system, alkali-treated activated carbon fiber filters are considered to be far superior to the commercial non-woven filters or combination filters currently commonly in use.

The purpose of this study is to suggest the design guidelines of exhibition space for conservation of collection in a museum. With the purpose of this study, examined the concept and a condition of conservation which is focused on deterioration in a exhibition space, investigated the actual condition of total 42 facilities and analyzed the specific instance which is excellent by factor of environment plan. Hereupon, the results of this study are as follows. First, exhibition space should be equipped with sufficient 'Filtering Space' before the outdoor and located central territory in a museum facility. Second, exhibition space should be partition off an area into the quality of collection, and then controlled by each of them. Third, in consideration of the annual air fluctuation of our country, the database which is adaptable for setting up the standard of temperature and RH must be prepared. Fourth, it is necessary to establish a 'Reference Exhibition Room' which is formed cellular type and a 'Garnering Exhibition Center'. Fifth, for the prevention of deterioration which is generated in exhibition space, the showcase must be high air-tight. Sixth, it is necessary to reduce a inside space of high air-tight showcase. Seventh, art-sorb is suitable for control the organic matter of collection and a except of fiber optics is not suitable for lighting of showcase. Eighth, wall-type showcase should be have air-chamber which is formed like museum storage and run over 8 hours a day.

Nowadays, according to many studies, indoor space's pollution level is two to ten times higher than outdoor space's. This result arouses our attention. The major causes of deterioration of indoor air quality are the lack of ventilation caused by draught-proofing and insulation construction, and harmful chemical substances emitted from building materials, office machine and furniture. Therefore, we are continuing research to find the method for healthful house and production of many forms of well-being goods. However, because of exaggerated advertisements and the lack of accurate information, consumers choose the products whose performance is not verified. Therefore, this study investigates the actual conditions of pollution by building materials and the extent of the health damage by this pollution, and suggests the method for minimizing indoor pollution in aspect of indoor environment control and the use of environment friendly materials. But the building materials presented in this study are limited to the environment friendly construction materials that are in circulation In domestic market because this research is primarily aimed to give domestic consumers the standard for selecting this materials.

Indoor air quality is a very important environmental factor in modern society. However, air pollutants generated from various interior construction materials significantly affect the human body, including formaldehyde (HCHO) and volatile organic compounds that threaten public health by deteriorating indoor air quality. Effective in removing these harmful substances are porous materials, such as woodceramics. In this study, charcoal, a porous material, was added to rice husk, an agricultural by-product, and sawdust generated during the sawing process to prepare boards and ceramics at different mixing ratios, and the HCHO deodorization performance and far-infrared emission characteristics were measured. As the mixing ratio of charcoal increased, the deodorization rate of the boards and ceramics tended to increase. Overall, the deodorization rate was measured to be 80% to 90%, indicating that the boards and ceramics prepared with charcoal are suitable to be used for the purpose of deodorization. The effect of the material mixing ratio on far-infrared emissivity and emission power was insignificant.
