In previous research, most occupant said that they have not operated ventilation system installed in the house, because of increasing of energy consumption and unconcern of ventilation. Therefore, it is necessary to applied the sensor based demand controlled ventilation for the IAQ(Indoor Air Quality) and improvement of energy efficiency in ventilation strategy. The propose of this study is to present a application method of IR(Infrared) sensor for multi-zone DCV(Demand Controlled Ventilation) in the apartment house. It is possible that IR sensor could be used for DCV, because that could detect the occupant and action. IR sensor based DCV strategies are established to evaluate characteristic of application in the apartment house and simulated by Contam program. As a result, they have some week points though, if they would be applied DCV with optimum strategy, it would be useful to improve IAQ, to reduce energy consumption.

An apartment house with a pilotis that raises the architectural volume and provides a space for circulation is becoming popular. With the popularity of pilotis in apartment houses, people also have a keen interest in the potential fire risk at the pilotis. As residents can only access their apartment house through the pilotis, there is a risk to the occupants if there is fire there. Therefore, this study evaluated the pilotis fire cases of urban multifamily housing to conduct a Fire Dynamics Simulator (FDS) and Fire Evacuation Simulation (FES). Through these two simulation methods, it is possible to validate the riskiness of fire at an apartment with a pilotis. The study identified that the toxic gases and flame spread out to the pilotis within hundred seconds after ignition. In addition, the toxic gases and flame also reach the second floor within three seconds and the entire building within 735 seconds if the entrance doors at the pilotis are opened. On the other hand, the FES simulation results showed that it also takes about approximately 609 seconds to excavate from the apartment house with a pilotis. Therefore, this research shows that an apartment house with a pilotis can ensure the building occupants' lives and their safety if there is fire.

This study was intended to suggest that new small-sized apartment houses should be designed and provided on the base of the concept of universal design. This is based on the diversity of each resident, that is, resident of not as a family, but as an individual. On the background of this, this study evaluated the small-sized apartment house in aspects of universal design. The walk-through and the residents' evaluation were carried out by using 60 items related to the principles of universal design. The 18 pyung apartment complex and housing unit in Jangyou new town area was evaluated. Also, 100 residents living in that apartment housing unit were asked to evaluate these 60 items by using 5 point Likert scale. The walk-through with measuring and taking pictures was carried out by researchers. In general, the apartment house was not met the fundamental elements of universal design. Thus, it was not appropriate for the disabled or the elderly to live in. Specially, the door width of bathroom and kitchen balcony was too narrow to pass through. Also, the floor of entrance and bathroom was not flat, so that the wheelchair user cannot enter by alone. The residents evaluated negatively many items related to design, such as shape, color, and material. Therefore, in order to provide the living environments for diverse residents such as the elderly, or the disabled to live together, the new small-sized apartment houses should be designed on the base of the principles of universal design.

The purpose of this study is to analyze the structure and use change of the private space according to the balcony expansion and use it as the data of plan design. According to Bay, front length/width ratio and the change of balcony space before and after expansion of space organization of house units were analyzed. Common characteristics of Flat type and Tower type are an increase of the frontage length of house units in an apartment, an increase of the number of front bay, and an increase of integrated LDK focusing on living room. A difference is that Flat type shows high frontage ratio, Bay figure, and spatial arrangement favorable to front openness and lighting. Flat type shows higher area distribution than Tower type in LDK area distribution located in at the plane center. Spatial expandability and visual openness of Flat type are more beneficial than those of Tower type in the planning, and a balcony extension of house units has developed to direction to open more. Tower type creates various block images through a combination of house units focusing on the core. Uses after balcony expansion are area expansion of a balcony-neighboring room, storage space, expansion and function improvement of the variable range, and specialized space different from a neighboring room. In addition, there is no escapable space except for a shelter, so unit plan should be prepared to prevent using it other space of a shelter and to solve moving line of two-way horizontal refuge and vertical refuge.

Putting a high value on individual preferences is a modern trend that more and more companies are considering for their product design and development and the apartment design is not an exception. Most apartments today are built using similar design with no room for customization. People in general want their tastes to be reflected in the design of their apartment. However, delivering what customers like to the construction company may not be an easy task in practice. For this reason, an intuitive and effective medium between the company and customers for effective communication is needed to ameliorate such a difficulty and in response to this necessity, we developed a test platform for the virtual model house which provides a user with the customization of the apartment using haptic interactions. In our virtual environment, a user can explore an apartment and change the interior based on their taste and feel through intuitive haptic interactions.

In this study, As a basic research for improving indoor thermal environment at tower type apartment houses, specifications of heat storage and heat emission in the structures of apartment houses were investigated, and the ratio of indoor and outdoor air velocity at tower type apartment house was examined, too. Indoor temperature at night time was higher than outdoor air temperature because heat emission from the structure of wall, ceiling and floor those are constructed by use of reinforced concrete which has large heat capacity. The ratio of indoor and outdoor air velocity was lower than 0.1 and this was caused by the plan of tower type apartment house. PMV was in the range of 0.3~1.9, and was about 1.0 (it means slightly warm) at 10 : 00 p.m.. To improve indoor thermal environment in summer season at tower type apartment houses, it needs more investigation on specifications of heat storage and heat emission in the structure including winter season, and on the improvement of the ratio of indoor and outdoor air velocity.

As an alternative approach to evaluate the unit heating load for apartment houses, we newly developed and proposed unit building method. The new method, which calculates the heating load of an apartment building as a whole, conceptually corresponds to integral analysis of building heat loss, while the existing unit apartment method to differential analysis. Four typical building models of Korean-style apartment house and two dynamic load calculation programs were selected to validate the present method under realistically imposed conditions. Eight sets of unit heating load calculated respectively by unit building and unit apartment methods showed excellent agreements regardless of building model and simulation program. It is expected that the unit building method can take the place of the unit apartment method due to fewer modeling assumptions as well as less computational efforts. Additional calculations to investigate the effects of various parameters on unit heating load yield good consistencies with known facts, and re-confirm the validity.

The purpose of this study is to understand various styles of Korean house living, up to the present, to identify apartment living as the main house living, and plan and propose the interior unit spaces for apartment house based on the analysis on living space. A survey study was conducted to deduce the traditional major life style and its changes along with favorable housing spaces. In conclusion, this study proposed the unit space planning requirements that satisfies the conceptual and interior elements for habitant's characteristics and preference according to major life style as follow; 1) As the Ahn-bang(master bed room) has been changed from traditional space concept, it is mainly used as private space for husband and wife, and its utilized period is mostly at night time, the back-arrangement of the Ahn-bang should be considered. 2) As the living room is central space in the apartment housing and has complex functions which is utilized as space for family gathering and guest reception similar to the Ahn-bang of the traditional house, it should secure more space and it is desirable to arrange the space as open type by combining the pathway area. 3) As for the kitchen/dining room, the kitchen should be isolated from external attraction and the space for storing and preparing traditional foods should also considered, and the dining room should be arranged as open type. This study also suggests that since the apartment housing must be an integrated environment for habitants which satisfy behavioral, physical and mental elements simultaneously, the unit housing space should be constantly analyzed in various ways to produce a housing space which meet both their changing major life style and the temporal environment.
