Development of temporary housing for victims whose house damaged is required. In this study is to plan temporary house space 'Mobile Energy Shelter House ; MeSH' that can be inhabited for a long time. And measure the indoor Environmental performance. 'Mobile Energy Shelter House : MeSH' was made by reflecting Passive Design, Universal Design. Also, thermal insulation that meets the 'Korea standard insulation' for use low energy. Winter season, measuring temperature, humidity, air velocity and radiation temperature when floor heating that temperature controllers ware installed is used. Confirmed the data for the 8:00pm to 8:00am because evening hours are expected as residents live. Average outdoor temperature was $-11.3^{\circ}C$ and Indoor temperature was from $16.09^{\circ}C$ to $20.63^{\circ}C$. Calculated the TDRi of the window surface for checked condensation risk. TDRi value was 0.185. Furthermore, PMV value was -0.08 to -0.85. It was satisfied to ISO comfort criterion ranged.

Environmental problems have showen over the past decades due to the rapid development of the world economy and the continued growth of the population. Ocher has been widely used for water treatment research, but few studies have been conducted on adsorption of air pollutants using ocher and porous diatomite earth for indoor air purification. In this study, ocher and diatomite earth were sintered with filters to remove indoor air pollutants. The four types of TMA, H₂S, NH₃ and CH₃COOH were used to study the adsorption efficiency of ocher and porous diatomite filters. With the proper use of ocher, diatomite and copper catalysts, indoor air pollutants could be adsorbed. Alkaline substances (TMA and NH₃) and acidic substances (H₂S and CH₃COOH) were able to adsorb at 120 and 90 minutes, respectively.

The objective of this study is to analyze the major factors of indoor environment that affect the satisfaction of the occupancy in multi-family residential buildings. The results of this study can contribute to improving the comfort of the residents effectively as they are applied preferentially at the design and construction stages. The indoor environment factors investigated for the analysis included thermal, light, air and the acoustic environment. The individual factors were derived from the 'indoor environment' assessment indices of the green building certificate systems of various countries. Based on these, a questionnaire was prepared to conduct the Post Occupancy Evaluation. The survey results were statistically analyzed.

Double-Skin Façade (DSF), which is a kind of passive indoor environmental control technique, is effective way to control environmental loads while maintaining the transparency especially in perimeter zone and hence the adoption example of DSF keep increasing recently. The objective of this study was to perform a field survey of air quality environment with natural ventilation through DSF and thermal environment within office building with six stories during a mild climate period in Japan. Moreover, to understand the comprehensive environmental performance of the target building, questionnaire survey was conducted to subjectively evaluate the productivity and satisfaction with the environmental factors in office space. In this field measurement, there was a positive correlation between the DSF internal ventilation flow and the amount of solar radiation on the DSF normal surface; the primary driving force for ventilation in the DSF was considered to be the buoyancy force caused by solar radiation. The results of questionnaire survey with regard to productivity level indicated the need for improvement in the thermal (temperature) and spatial environment (room size and furniture placement).

The purpose of this study is to provide the basic data for passive control and energy conservation strategies of multipurpose greenhouse. Passive design strategies which are appropriate to Jeju environmental circumstance were applied in the multipurpose greenhouse. The field measurement were conducted to examine relationship of micro climate and indoor thermal environment in the multipurpose greenhouse. The result of this study can be summarized as follow ; (1) The indoor temperature was ranged from 5 to $21^{\circ}C$ without a heating system, when the exterior temperature was -1 to $19^{\circ}C$. (2) The multi-purpose greenhouse requires almost no heating energy in winter, when it is used as a greenhouse, an exhibition hall or a cafeteria.

For computer aided design and costruction of low noisy power plants, indoor and outdoor noise prediction program has been developed. The program utilizes the predefined data of noise sources and building materials and has the faculty to estimate the source level using the empirical formula in case of the measured data not being available. In the noise prediction, the mutual noise propagation between indoor and outdoor sites are considered. The outdoor noise source in the calculation of geometric divergence effects is modelled as the omni-directional finite line or planar source according to the source geometry and the receiving points. Outdoor noise prediction is carried out to consider the diffraction effect due to plant structures as well as the attenuation effect due to atmospheric absorption and soft ground. The results of indoor and outdoor noise prediction for a recently constructed diesel engine power plant show good agreement with the measured.

There is growing consciousness of the environmental performance of buildings in Hong Kong. The Buildings Department, the Lands Department and the Planning Department of the Hong Kong Government issued the first of a series of joint practice notes [1] to promote the construction of green and innovative buildings. Green features are architectural features used to mitigate migration of noise and various air-borne pollutants and to moderate the transport of heat, air and transmission of daylight from outside to indoor environment in an advantageous way. This joint practice note sets out the incentives to encourage the industry in Hong Kong to incorporate the use of green features in building development. The use of green features in building design not only improves the environmental quality, but also reduces the consumption of non-renewable energy used in active control of indoor environment. Larger window openings in the walls of a building may provide better natural ventilation. However, it also increases the penetration of direct solar radiation into indoor environment. The use of wing wall, one of the green features, is an alternative to create effective natural ventilation. This paper therefore presents a preliminary numerical study of its ventilation performance using Computational Fluid Dynamics (CFD). The numerical results will be compared with the results of the wind tunnel experiments of Givoni.

Sustainable interior design is defined as interior design in which all systems and materials are designed with an emphasis on integration into a whole for the purpose of minimizing the negative impacts and maximizing the positive impacts on environmental, economic, and social systems over the life cycle of the interior components of a building. To achieve sustainability, it is important to pay attention to the design factors that significantly affect environmental eco-system. The purpose of this study was to describe how interior designers applied sustainable intoner design factors and how important they perceived sustainable interior design factors to be. Internet-based survey of interior design practitioners was conducted to collect data. A random sample was drawn from the American Society of Interior Designers membership list. Findings indicated that although interior designers acknowledge the importance of sustainable design practice, they have not frequently applied it to their projects. The results of this study suggest future educational strategies for students majoring in interior design and continuing education for intoner design professionals.
