Recently, the size of Large Space has been gradually enlarged, according to the development of technology, and because they're used not only for indoor events, but also for various outdoor sports, for example, baseball or soccer. Therefore, there are more demands for developing indoor environment control technology to establish indoor thermal-environment which is proper for different events held in Large Space. This study aims at offering some basic data which can be referred to as the construction guide for the full-scaled construction of Large Space in Korea by arranging the matters to be attended to in designing, and controlling technologies for efficient Large Space design.

최근 건축기술의 발달에 따라 초고층 건축물 및 지하시설물과 연계된 복합건축물 등과 같이 건축물들이 대형화 되고 있으며, 실내에서 활동하는 인구도 함께 증가하고 있다. 이에 따라 실내공간정보를 이용한 위치 기반서비스에 대한 요구도 증가하고 있다. 실내공간에서 효과적인 위치기반서비스를 위해 OGC IndoorGML 표준에 따라 실내 네트워크가 구축되고 있다. 하지만, 크고 복잡한 실내공간에 대해 단순한 네트워크 구조를 적용하여 실내 네트워크를 구축하는 것은 적합하지 않다. 실내 네트워크는 실내공간에서 주어지는 논리적, 물리적, 기능적 제약조건들을 잘 반영하여 구축되어야 하며, 공간간의 연결정보와 기하정보도 제공해야하기 때문이다. 이를 위해서는, 크고 복잡한 실내 공간을 적절한 크기의 공간으로 분할하는 방법이 필요하다. 이에 본 연구에서는 효과적인 실내네트워크를 생성하기 위해 필요한 실내공간 분할 요구사항을 정리하고 그에 따른 실내공간 분할 프로세스를 제시하였다.

This paper addresses the indoor air quality when radiant floor heating is applied in large space. Radiant heat exchange between surfaces depends on the orientation and the temperature of the surfaces. Also, the temperature and the radiant characteristic of the wall and the roof that face the floor have great influence on the indoor air environment due to the largeness of the wall and the roof in large spaces. In this study, we simulate a test-cell(25X20X10) using a ies YE And using a CFD(microflo in VE), an indoor air environment was investigated to establish the optimum temperature of floor. At the first time of the heating, high floor temperature is demanded. At the middle of the heating, however, the temperature of the residential space was formed appropriately, although the temperature of the floor was set low.

Due to an increase in the number of large-scale and high rise buildings, the importance of indoor location information has been highlighted. As a result, seamless three-dimensional space information, linked to various indoor and outdoor services is required. The purpose of this study is to develop a system which can edit and operate indoor space information using the IndoorGML(Geography Markup Language). It provides functions such as converting and editing authoring indoor space using the IndoorGML. Based on defined schema which is the IndoorGML international standardization work, we develop the "Editor" and "Viewer" for the IndoorGML. When indoor space is modeled in an authoring tool, a variety of topologies can be created automatically. These are available to be edited and modified. Moreover, the file of model can be saved as IndoorGML, SBM and KML file. These files are viewed by the "Viewer". Indoor LBS(Location Based Service)is served with these principles.

CFD code are used for numerically testing a new concept of large space air control system. A workshop with air-conditioners products lines and air-conditioned by several floor type air-containers is tested. The whole room air distribution is controlled by boosters installed in a middle height horizontal plane. First, calculated results are compared with measured data to confirm the validity and applicability of the prediction method. Next, the method is applied to case studies heating seasons. Results under some operating conditions show effectiveness in avoid the temperature stratification in winter.

In Korean apartment housing, balcony is semi-outdoor space for storage and drying laundry. Recently, this semi-outdoor balcony space has been merged into indoor living space with the legal permission of balcony extension. It results in disappearance of the original function of balcony in apartment housing. This study attempts to propose better utilization of balcony extension by analyzing how balcony has been extended and used, and what residents' needs are. This study asks 400 housewives living in apartment housing in Jangyu new urban area, Kyungnam. Findings are : 1) Balcony extensions are carried out in a living room, a large bedroom and a small bedroom. Most extensions are made for enlarging adjacent indoor living space; 2) Original balcony that is not extended is used for drying laundry, resting, flower pot, storing, and kid's playing; 3) The residents recognize that problems of balcony extension are the decreased heating efficiency, the reduced soundproofing effect, the loss of spare housework space, and the disappearance of buffer between indoor and outdoor space; 4) Many residents want to extend their balcony space of a small bedroom and a large bedroom and to keep the balcony space of a kitchen-dining room and a master bedroom as they are.

PMV and ADPI were numerically investigated in a large space of various ceiling height with air-conditioning systems of two type. The numerical results showed that it is small that the growth of cooling load according to ceiling height rise in a large space without windows. In case of system air-conditioner of duct type embedded in the ceiling, the air mixing effect in indoor is superior to a case installed 4way cassette type in it. For controling thermal comfort at indoor, a system air-conditioner of duct type embedded in the ceiling is little influenced according to ceiling height rise in a large space considered.

In this study, an analysis is carried out on the acoustic design for an indoor gymnasium scheduled to be built at Buan County, Chonbuk Province. By way of background, the study examines the case of a large-scale indoor gymnasium that has been constructed in the local area of Hangan-myeon. There are many examples whereby this gymnasium could be used not only as a sporting facility for the residents, but also as a multipurpose space for public performances such as leisure activities, lectures, assembling activities, theatre and concerts etc. In order to maximize the functional utilization of such an indoor gymnasium, it is important to simultaneously verify the acoustic capabilities of the space in terms of Definition of both Voice and Music. However, as a large-scaled athletic facility, the building was designed with a high ceiling-height to accommodate its functional characteristics. The space forms a Sound Focus whereby the sound is concentrated at a specific part, and because the vibration of sound is too loud due to its broad volume, acoustic defects arise such as a significant number of Echoes. Using this gymnasium as a precedent, this study proposes an acoustic design based on the drawings of the indoor gymnasium that is scheduled to be built at B County, Chonbuk Province. The gymnasium is equipped with an optimized acoustic condition passing through the Acoustic Simulation Phase. From the results of an Acoustic Simulation, we can design an indoor gymnasium that is equipped with a considerably satisfying and improved acoustic performance compared with the building before it was reformed. It is also considered that the use of such materials can fundamentally reduce construction costs and can improve acoustic performance, at the planning and design stages for similar sporting facilities in the future.
