The purpose of this study is to analysis the performance of heating energy reduction and the comfortableness of occupants using fuzzy control in a radiant floor heating system of apartment. To achieve this purpose, the experiment was conducted at experimental house for eight days. The result of experiment shows that the fuzzy control is a efficacious method to reduce the heating energy and to improve the comfortableness of occupants. However, this study is in the early phase so more in-depth study is required after this.

Natural ventilation is an effective method for improving IAQ(Indoor Air Quality) and removing heats in buildings. In oder to use natural ventilation, many factors such as wind pressure around the buildings and possibility of air intake on different shapes need to be known. On this paper, the natural ventilation performance in multi-housing units of tower-type buildings was investigated. Tower-type multi-housing buildings are recently more and more constructed for they may change urban landscape and get more openness in multi-housing site. However, such housing buildings have problems with natural ventilation because of the various directions of the building units. The purpose of this paper is to find the proper building direction regarding to wind direction in order to optimize air intake in every units in the building.

Internal heat gain describes occupants' life style and it contributes energy consumptions in residential buildings. And the heating, cooling and lighting system operation schedule are also very significant. A standard heat gain and schedule of residential building has not been exist in Korea so that the researchers have made and used their own schedule. In this study as a start, the data which can describe occupants' energy using patterns are gathered and analyzed. the life time use survey, energy consumption pattern poll and power consumption pattern survey data are used to analyze occupancy schedule, lighting schedule, equipment schedule, heating and cooling system operation schedule and natural ventilation schedule. These can compose a standard heat gain and operation schedule of residential building after verification process.

Natural ventilation is an effective method removing heats in buildings. In oder to use natural ventilation, many factors such as wind pressure around the buildings and possibility of air intake on different shapes need to be known. On this paper, the natural ventilation performance analysis on different adjacencies to out door and plan arrangements were done through pollutant concentration on each room by the diffusion of pollutant with the ventilation. 'Open end type' showed better ventilation performance over rall compared to the 'open at right angle type', and revealed that the larger area of living space on airflow area led to less concentration of pollutant. The first, diffusion of polluted material should be prevented. The second, proper distribution of airflow should be done in all areas of the each housing to avoid non-flow area. The third, the formation of short cuts should be avoided.
