Purpose : Currently, 25% of the domestic energy consumption structure is used as building energy, and more than 18% of this energy is consumed in the residential. Accordingly, various efforts and policies that can save energy of the building is being performed. The various researchers are conducting research to diagnose the thermal performance of existing buildings. This study is to apply in the field of precision thermal insulation performance diagnostic method for thermal performance analysis of existing detached house in Seoul, Gangreung, Gyeongju, Pohang. And this paper is analyzed quantitatively measure the existing detached house energy performance. Method: Research methodology analyzed the thermal performance over the Heat Flow Meter method by applying the measurement process and method by applying the criteria of ISO 9869-1 & ASTR method. In this study, the surface heat transfer coefficient was calibrated by applying indoor surface heat transfer resistance with reference to ISO 6946 standard. The measurement error rate between the HFM diagnosis method and the ASTR diagnosis method was reduced and the measurement reliability was obtained through measurement method error verification. Result : As a result of the study, the thermal performance vulnerable parts of the building were quantitatively analyzed, and presented for methods which can be improved capable of efficient energy use buildings.

전 세계적으로 에너지 절감, 온실가스 감축 등을 위한 다양한 방법이 제시되고 있다. 우리나라에는 노후된 주택들이 많아 이에 대한 리모델링의 요구가 많으나 이에 대한 연구는 부족하였다. 본 연구는 노후된 주택들의 유형을 분석하였고, 국내 외 사례와 기존 연구를 통하여 리모델링에 적합한 기술 리스트를 제시하였다. 창호, 단열, 문 등과 관련된 기술에 에너지 시뮬레이션, 경제성 분석을 실시하여 소규모 주택 리모델링에 적합한 기술의 조합을 제시하였다. 본 연구는 소규모 주택에 적용할 수 있는 기술의 성능, 경제성을 위한 기초연구이며 이외의 더욱 많은 기술의 분석의 기초가 될 것이다.

본 연구의 목적은 기존 공동주택을 에너지절약주택인 그린홈 주택으로 개보수하기 위해, 개보수의 수요정도와 우선순위를 예측하는 기초자료를 취득하는 것이다. 이를 위해, 입주한지 약 10여년 이상의 공동주택 단지에 살고 있는 세대를 방문하여 거주자의 그린홈 개보수에 대한 제반 의사들을 조사하였다. 조사내용으로는 일정수준의 재정지원이 있을 경우, 개보수 의사와 개보수 선호항목 등이다. 총 1,400만원을 이율 년 3.5%로 융자 지원할 때, 거주자의 53%가 개보수할 용의가 있다는 의사를 표시하였다. 또한 개보수 선호대상으로는 창호가 가장 높았으며, 일상생활에 불편을 주는 항목들은 현실적으로 개보수가 어려울 것으로 조사되었다. 본 설문조사는 공동주택에 대해서만 한정되어 있으며, 향후 단독주택에 대한 설문에 대해 추가 연구가 진행되어야 할 것이다.

Purpose: Residents in deteriorated residential areas of Seoul have suffered from parking shortage problem. Since it is almost impossible to supply new parking, it is critical to find a way to efficiently utilize existing parking spaces. This study proposes utilizing unused parking spaces in apartment complexes so that residents in multi-unit or multi-family houses can share those parking spaces. Method: Spatial scope of this research is limited to multiplex-clustered neighborhood and apartment complex in Seoul. To identify the nature of parking problem, we reviewed current parking situations in residential areas and policies from the Seoul Metropolitan Government. To understand the amount of parking spaces required to solve parking shortages in multiplex-clustered neighborhoods, this study analyzed car ownership per household and available parking spaces in old residential areas. Then we were able to apprehend the amount of parking spaces that could be used for residents in aged multiplex-clustered areas. Result: Our analysis shows a great potential to utilize surplus parking spaces from apartment complexes for solving parking problems in multiplex-clustered neighborhoods.

Urban space structure in South Korea when through drastic changes ever since public housing policies began their full-fledge implementation. That is, public housing policies represent the main cause for formation of the current urban space structure, as the public houses are constructed in accordance with changes of demographic/social structure, considering changes of housing demand, in urban spaces demanded by the end users. After rapid industrialization and urbanization in the 1960's, each government in different periods have implemented housing supply policies through massive urban developments, to resolve the issue of housing shortage and residential instability. Phase 1 New Towns were developed in the 1980's resulting in suburbanization of the Seoul Area, followed by urban sprawl due to construction of small-size New Towns after deregulation in the 1990's, and construction of Phase 2 New Towns for resolution of housing shortage in the early 2000's and the resulting urban problems. In the mid-2000's, construction of Bogeumjari houses in GB areas led to insufficient housing supply in downtown areas, and the period after 2010 witnessed continuous deterioration of existing urban areas and acceleration of the rental housing crisis caused by rental housing shortage in downtown areas. Moreover, the residentially vulnerable classes consisting of young, 1~2-member households is expanding, with the real estate market in recess. Therefore, the government is trying to achieve urban regeneration through public housing policies so as to resolve the urban space problem and the housing problem at the same time, and the Happiness Housing Project has been implemented as a policy to achieve that goal. The Happiness Housing Project for young, residentially vulnerable classes in downtown areas, is going through diversification aimed at conjunction with urban regeneration projects in downtown areas, as exemplified by conversion of rental houses in residential environment improvement project districts and redevelopment/reconstruction project districts into happiness housing, and supply of happiness housing in conjunction with small reorganization projects for deteriorated residential areas in such areas as those excluded from New Town designation. Continuous supply of Happiness Housing in conjunction with urban regeneration requires mixed-use residential development which includes convenience facilities and public facilities, along with improvement of rental conditions (rental period/rent) and diversification of project methods, considering that the project is implemented in downtown areas.
