The purpose of this study was developing the building materials for creation the comfortable IAQ. By reducing formaldehyde(HCHO) known as the main factors of Sick House Syndrome. This building materials must be revealed the eco-friendly performance, so this study set up the humidity control characteristic for building materials. The source of basic performance evaluation is Korea Industrial Standards and the base of environmental ability is the Eco Label considering certificated system related to an apartment house. Because the developed material was satisfied with the established standards, it was tested in mock-up room for obtaining the real date from indoor air humidity and temperature. The mock-up test was conducted according environmental standard method for indoor air quality of the ministry of environment. The result of this study were as follows; the humidity control characteristic building materials had a effect to control the indoor air humidity.

Recently, functional building materials have been developed and introduced to the market. Many building materials emit volatile organic compounds(VOCs) which have the potential to affect health and comfort, and moisture problem has a major role also being established in indoor air quality (1AQ) problems. The purpose of this study is to evaluate the performance of reduction of HCHO using the gupsum board and water vapour adsorption/desorption property for ceiling board for mock-up test room and test house. The mock-up test is conducted according environmental standard method for indoor air quality of the ministry of environment. The results of this study are as follows; the reduction of HCHO gypsum boards are showed an effect to reduce the formaldehyde(HCHO) concentration of mock-up test room and test house. The indoor humidity is also showed to be lower than the general ceiling materials, since there is increased in the absorbed indoor humidity by using a humidifier with moisture adsorption/desorption ceiling materials. In natural conditions, moisture adsorption/desorption ceiling materials is showed a higher humidity than general ceiling materials constructed in the mock-up test room. However It changes of moisture adsorption/desorption is not appeared in test house. Therefore, in case of decreasing and increasing in humidity, these materials can be offset by reduction of HCHO using the gypsum board.

The purpose of this study was developing the building materials for creation the comfortable IAQ. By reducing formaldehyde(HCHO) known as the main factors of Sick House Syndrome. This material must be revealed the physical and eco-friendly performance, so this study set up the basic standards for building materials. The source of physical performance evaluation is Korea Industrial Standards and the base of environmental ability is the Eco Label considering certificated system related to an apartment house. Because the developed material was satisfied with the established standards, it was tested in mock-up room for obtaining the real date from indoor air. The mock-up test was conducted according environmental standard method for indoor air Quality of the ministry of environment. The result of this study were as follows: the functional building materials had a effect to reduce the formaldehyde concentration for a initial period without wall paper, so additional development is needed for application with the wall paper and the available period.

The purpose of this study is to evaluate the performance of wall type ventilation systems heat exchange unit adapted. Performance of ventilation systems was estimated by a ventilation rate, ventilation effectiveness and power consumption. Experiment was performed in a thermal environmental chamber that heated by a electric heating cable. A tracer gas technique was used to measure ventilation effectiveness of ventilation systems. A tracer gas of CO₂ was injected in a chamber using step-up method. The results of this study can be summarized as follows. (1) The air infiltration rate of the chamber was calculated by 0.5 ACH. (2) Effective ventilation rate of each ventilation system was estimated by 60 percent of a ventilation airflow rate. (3) The ventilation effectiveness of ventilation systems was measured by 70 percent. (4) Energy saving rate of a heat recovery wall type ventilation system was improved 28 compared to general wall type ventilation system.
