KIEAE Journal, volume 9, issue 5, 2009, Pages 3~12
High-rise apartments in Korea has physical, environmental, social, economical superannuation. But the remodeling of their apartments is focused on the physical improvement. So they remains the problems of community, safety, economy. Remodeling have to do is to attempt to synthesize the whole superannuation. So we select the B-maul apartments in 1st new towns has the typical problem(parking unsufficiency, small pyeong, ecology shortage etc) of high-rise apartment in the country and analysis its superannuation and remodeling plan. And verify the propriety of a remodeling plan to improve superannuation through an expert survey. Through the tasks, high-rise apartment remodeling in the country need to have a cure for the problem : lowing of the ceiling heights, a shortage of understanding among the residents, and insufficient improvement in the surroundings, no reuse-energy system.
A Study on Process for District Office Building Maintenance with EPIQR+ (on Focusing Energy and Economics Evaluation)
Kim, Tae Han ;
KIEAE Journal, volume 9, issue 5, 2009, Pages 13~20
This study suggested practical application of decision aid tool on re-evaluation of current buildings with a focus on a energy and economics evaluation methodology. In Europe, over forty percent of all construction activities are for retrofit. For efficient construction, various tools for re-evaluating existing buildings have been developed and are in use. Legislations of relevant laws and studies are actively initiated. In particular, EPIQR (Energy Performance Indoor environment Quality Retrofit), which was developed through the EU's Third and Fourth Framework Programs laid a foundation on a new concept-based decision aid tool for re-evaluation of existing buildings. As for actual applications, based on this, EPIQR+ was developed to be in line with a building maintenance guideline (SIA 469) and is actively applied to public buildings. This tool quantifies the degree of damages of existing buildings and suggests alternatives to users in energy (SIA 380/1) and economical perspectives. This study examined these preceding tools and suggested some trenchant approaching for more comprehensive and efficient use of re-evaluation tools in building maintenance.

KIEAE Journal, volume 9, issue 5, 2009, Pages 21~28
In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

Most Plastic Green Houses in Korea are made according the European weather condition, which lead to have very low solar energy efficiency. Moreover, the function of green houses, as well as the structure of them, has not changed for Korean weather condition. Therefore, the structure and function of them should adopt the regional weather condition in order to improve the energy efficiency. This paper investigates the current plastic green housesin Korea, and presents an alternative for improving the energy efficiency. The elements of green houses were investigated. When using a partial opaque insulation with a thermal storage body, the difference of indoor air temperature became 20C during daytime, and 5C during night, which will save massive fossil fuels.
To reduce carbon from residential architecture Research on energy-saving elements
Park, Jae-Hee ;
KIEAE Journal, volume 9, issue 5, 2009, Pages 47~52
Currently, the environmental issue is of great urgency and sensitivity to the future of our planet. Global warming caused by increased CO2 concentration has an alarming impact on the earth's fragile environment. Droughts throughout the world are causing crop failures. Wildfires now burn with far greater rage. Melting ice caps and glaciers are causing floods. Sea levels are rising. Warm unseasonable winters are threatening our fragile eco-systems. Global warming is no longer a theory; it is an obvious fact we are confronted with every day, and the only way we can prevent it is to take action now. The need to reduce CO2 emissions and try to become carbon neutral is of national importance and leadership. We have become so reliant on fossil fuels that nearly everything we do generates CO2 emissions; from our modern farming practices to transport, to the electricity used to turn on a light, boil water in a kettle or cook our meals. A reduction of 50% of CO2 emissions can easily be achieved by decreasing the energy amount used. We tracked the carbon footprint throughout the electricity and heating energy use in homes and confirmed the amount of carbon emissions according to its consumptions. In order to reduce the carbon generation from housing constructions, such as Passive House concept of buildings or low energy buildings, we must adjust its applications best fit to our conditions. And technical elements should be applied to improve our conditions, and the methodology should be actively sought. Most of all, each individual's recongnition who uses these elements is more important than any other solutions.

A dynamic model development has been given System Dynamics based on the causal structure. Thus, this study focused on searching the causal structure of certification criteria and verifying the reality of the model through simulation processing after developing a model. In conclusion, the development of dynamic evaluation method can be attributed to systematic evaluation for the criteria of Certification System.
Investigation of the sound insulation performance of balcony window through field measurement
Ju, Mun Ki ;
KIEAE Journal, volume 9, issue 5, 2009, Pages 63~68
As with the disappearance of a living room window due to the trend in apartment housing construction that prefers a larger, expanded living room, the sound insulation performance of the balcony window is becoming an important factor to determine the level of indoor noise at an apartment unit. Considering that the indoor noise inside an apartment unit is mandated by law at or below 45dB(A), the balcony window is increasingly assuming an even more important role. Sound insulation performance of the window was measured by examining differences in data involving varying angles of incidence of the sound source as obtained from the same balcony window. Also, acoustic intensity measuring was performed at and around the window to determine its sound insulation quality. Results of measuring on the sound source's angles of incidence indicated that the performance showed some differences in lower frequency ranges, though with no significance. Intensity measuring results showed that the sound insulation performance was reduced near the connection part of the window and the window frame.

KIEAE Journal, volume 9, issue 5, 2009, Pages 69~76
The purpose of this study is to provide basic data needed for planning and designing apartment community facilities in order to vitalize rental apartments. Outdoors community facilities of six rental apartments in Seoul were examined. The results are as follows. Firstly, the conditions of planning characteristics showed that the convenience is ranked as the highest priority of planning, compared to safety, friendliness and finally comfortableness. Community facilities are connected with the apartments and sidewalk providing convenient access for all apartment residents, there was little regard given to the features of comfortableness. Secondly, comfortableness of community facilities were shown to the lowest, compared to any characteristics. It is not easy to control noise and privacy in facility, and there are lack of near community facilities, for washing hands, drinking water and shielding from snow or rain, respectively. Thirdly, green facilities were shown to the highest applied friendliness more than other facilities. They were well outfitted with water space and gardening spaces, and robustly applied environment friendly materials and colors. Fourthly, resting facilities were shown to the lowest applied safety more than other facilities. Structure and material of facility are favorable but there is an absence of nonskid material and night-lightening system.

Moon, Jung Hong ; Lee, Joo Hyung ; Hong, Jang Pyo ;
KIEAE Journal, volume 9, issue 5, 2009, Pages 77~84
This study was initiated by the fact that Kangwon Land and large sized resorts was failed the financial benefit to the local residents. This research analyzed the best important tourist resource among the main tourist resource by perception interviewing local residents and related professionals. This study shows that the leisure resource was most important resource field in Jeong-Seon. So more attention to the leisure resources and investment them. Among natural attraction resources 'Hwa-Ahm cave and Hwa-Ahm mineral water' is estimated to have most potential for the strategic financial support. In leisure sector 'High One resort' is judged to be more important attraction resource by professionals but a case of local residents 'Dong-gang Rafting' and 'Rail Bike' were estimated more important resources rather than 'High One resort;. Lastly, in cultural resources, although the importance is a bit behind natural attraction and leisure resources, 'Jeong-Seon 5th day market' and 'Araree village' should be the core linking other related cultural resources. In order to activate tour industry and development of Jeong-Seon area, it is necessary to find identify of regional owned attraction resources and to build tourist attraction infra structure by selecting core bases of existing major attraction points and linking other various resources to those core bases.

Lee, Joo-Hyung ; Seo, Eui-Kweon ; Lim, Jong-Hyun ;
KIEAE Journal, volume 9, issue 5, 2009, Pages 85~96
This study analyzed a characteristic by types of urban regeneration helping the establishment of urban identity under social condition change. It will be foundation of sustainable urban development with strategy that secures world-wide competitive power. For this, sample cases that established identity from urban regeneration were reviewed about the main subject and the supporting subject in business side and hardware, software, system, and finance in design factors. 4samples each in inheritance intensification type and change creation type were selected and analyzed. The result said it is most effective to establish urban identity when inheritance intensification type is the private-centered for urban regeneration. And it is better to do the project that the main subject and the supporting subject are taken by the private or the private-leading partnership. It is necessary to manage the region and plan events with software design factors more than hardware design factors. In addition, for urban identity, it was found to be desirable to utilize and preserve fully current resources such as historical scenery and activate the communities than making new facilities. On the contrary, the project based on change creation type needs to be under the public management with innovative idea. Also, when it comes to design factors, facilities related to culture and art and community spaces should open and run actively. It is important for the region to improve its image by New design style such as TOD. In software side, it is important to manage the region by monitoring about urban regeneration business and solve social mix and employment problem. On the other hand, in terms of system and administration, both types don't show a difference in urban identity establishment, since it is same that both should make partnership and get a support of subsidy to be most effective.

KIEAE Journal, volume 9, issue 5, 2009, Pages 97~104
In the process of urban development, the increase in the number and the complexity of urban facilities gives rise to a variety of problems, such as increase in construction and maintenance cost. In particular, taking into account the fact that an emergency situation in an urban facility can cause substantial loss of property as well as casualties, it becomes important to intelligently perceive states of facilities and properly execute countermeasures through real-time monitoring. In recent years, practitioners and researchers have made efforts to improve current passive and manpower-dependent facility management systems to be more active and intelligent, by applying diverse ubiquitous computing technologies for the u-City project. In this study, after discussing major drawbacks of the conventional facilities management, the concept and the model of a sensor-based integrated intelligent management system for urban facilities are proposed. The proposed model, by analyzing and processing real-time sensor data from urban facilities, not only supports the management of individual facilities, but also enables the detection of complex facility-related events and the process of their countermeasures. This active and intelligent management of urban facilities is expected to overcome the limitation of the conventional facilities management, and provide more suitable facility management services for the u-City development.

KIEAE Journal, volume 9, issue 5, 2009, Pages 105~113
Daylighting provides the opportunity for both energy savings and improved visual comfort. An accurate estimation of the amount of daylight entering a building is the key step for daylight designing. This research aims to assess comparative daylighting performance of four different configurations of fenestration in case of unilateral windows and their variation under clear and overcast sky conditions. The selected window openings in this study were single punched, double punched, multiple punched and clerestory, and the area was same for each type of window. The experiment was designed for an office space using 1/10 scale model. Daylighting performance was evaluated by measuring the illuminance on work-plane height using Agilent data logger and photometric sensor Li-Cor. Thecomputer program ECOTECT was also used to simulate the pattern of interior illuminance distribution. Clerestory window showed the best performance in term of both illuminance level and distribution in the experiment. Multiple punched window provided more uniform illuminance distribution than single punched window. Lowest daylighting performance in the experiment was shown by double punched window.
