In order to address housing issues, alleviate the concentration of urban populations, and resolve other issues regarding residential spaces, large residential complexes have been developed in Korea since the 1970s. The changes to the residential culture due to such development projects propagated rapidly, making the apartment complexes the most representative form of housing in Korea. In developing such large-scale complexes, plans for public open spaces, which play an important role in formulating the quality of residential environment, have been mostly the same, only utilizing the spaces remaining after planning other types of spaces. The current study looks at the case of Tama New Town development project, a Japanese new town development project that has a similar public open space system in large scale residential complex development projects in Korea. In doing so, the current study aims to identify the features of public open space plans. In the conclusion, the study first finds that various public open spaces must be reviewed and introduced in term of predicting social demands. Second, the study suggests the policy-makers should actively introduce pedestrian paths as a public open space. Third, the study deduces the planning implications of applying the principle of original landscape preservation.

Since Paris Climate Change Conference in 2015, many policies to reduce the emission of greenhouse gas have been accelerating, which are mainly related to renewable energy resources and micro-grid. Presently, the technology development and demonstration projects are mostly focused on diversifying the power resources by adding wind turbine, photo-voltaic and battery storage system in the island-type small micro-grid. It is expected that the large-scaled micro-grid projects based on the regional district and town/complex city, e.g. the block type micro-grid project in Daegu national industrial complex will proceed in the near future. In this case, the economic cost or the carbon emission can be optimized by the efficient operation of energy mix and the appropriate construction of electric and heat supplying facilities such as cogeneration, renewable energy resources, BESS, thermal storage and the existing heat and electricity supplying networks. However, when planning a large residential town or city, the concrete plan of the energy infrastructure has not been established until the construction plan stage and provided by the individual energy suppliers of water, heat, electricity and gas. So, it is difficult to build the efficient energy portfolio considering the characteristics of town or city. This paper introduces an energy mix optimization(EMO) method to determine the optimal capacity of thermal and electric resources which can be applied in the design stage of the real large-scaled residential town or city, and examines the feasibility of the proposed method by applying the real heat and electricity demand data of large-scale residential towns with thousands of households and by comparing the result of HOMER simulation developed by National Renewable Energy Laboratory(NREL).

This study examines and analyzes view hindrance factors of high-storied apartment houses at small town like 'Eup' where county office locates and it is found that hindrance factors include designation of residential area and height, length and form of main building. On recognition of view, most subjects of research considered high-storied apartment houses hindered urban view and its regulation is needed. Apartment houses at small cities become main factors of hindering urban view because they were located randomly regardless of scale of city and surrounding situation, but there is no measure to control it. Accordingly, view control through enaction of regulations is urgently needed with establishment of guidelines such as height of large buildings including high-storied apartment houses, length of main building, location and regulation of exterior design.

The purpose of this study is to examine and investigate the characteristics of locational facilities and the purchase and leisure patters of residents with its focus on downtown streets of Yeongam-eup which is a eup-level small town. In the subject downtown streets, commercial and residential functions coexisted. While most locational facilities were small-scale sale(buy), food(eat), and employment(public institutions) facilities which were needed for neighborhood life and supporting daily life, the lack of facilities which supported leisure life(enjoy) and represented small town identity was found. The most common frequency of using downtown streets by residents was 'almost everyday'; the most common intention to use was 'to purchase daily things'; and the most common purchase good was 'groceries', followed by farming machines, books, and stationery. It suggested that the use of downtown streets was characterized by daily neighborhood life. In particular, it was found that expensive goods(more than 500,000 won) were commonly purchased in neighboring middle or large cities. Thus, it is necessary to consider the option and professionality of goods. Finally, it is necessary to consider residents' accessibility through reorganizing a street form from car-focused to pedestrian-focused.

Buildings are responsible for approximately 50% of current carbon dioxide emissions. Energy planning at a town and city scale needs a strategic approach, supported by strong planning policies. The purpose of this study was to investigate the urban scale grid-connected photovoltaic(PV) system for urban residential and commercial sector applications. The integration of PV technology into roof of houses is an approach that is being championed in Germany, Japan and United states etc. In the Korea, PV roofing systems already are given the large number of houses which are projected to be built by 2012. However unlike germany and Japan, urban scale grid-connected PV system is not yet installed. The solar city which is installed building-integrated photovoltaic system is available to use of renewable energy sources such as solar to meet demand, instead of fossil fuels, with the goal of realizing an ecologically oriented energy supply.

High-rise and high-density apartment complexes have been built and supplied on a large scale in the 1st period of the New Town project in metropolitan areas since the late 1980s. Now It has become necessary to improve those apartment complexes, which have serious deterioration problems for aging more than about 20 years accompanying simultaneity and a large scale. The purpose of this research is to develop the evaluating indicators to measure the level of deterioration of apartments inclusively and practically in order to regenerate apartments as sustainable residential environments. This study is composed of the following four parts; (a) establishing the conceptual model of evaluation of apartment deterioration, (b) selecting evaluation items, (c) constituting evaluation measurement, and（ｄ)weighting evaluation indicators. First, deterioration of apartments was conceptualized by physical. social, and economical aspects in terms of sustainable development and proposed the conceptual model of hierarchy structure of evaluation of apartment deterioration by literature reviews. Second, evaluating items were selected based on literature reviews of existing indicators and preceding studies about apartments of Korea and foreign countries. The evaluating indicators were identified as a total of 77 evaluating items which were composed of three dimensions and 9 attributes on the basis of the conceptual model. They cover comprehensive scope of the apartment such as unit, building, complex, and site. Third, as the measurement, the 5 point ordinal scale measure was suggested. The evaluating measurement including measure standards, measure methods, and measure contents were developed by each evaluating items. Lastly, the weighting of evaluating indicators was analyzed by AHP method conducted by survey on the expert group. Items were identified as high contributors or low contributors. The weighting of these items could suggest several evaluations according to the situation. The evaluation of the level of deterioration can be done by both total evaluation and a specific field of evaluation. In addition, it is easy to grasp deteriorated attributes or dimensions by providing a radar and bar chart showing evaluation results. These evaluating indicators could be a useful tool to grasp actual methods for the regeneration of apartments.

주택에 대한 수요가 다변화되면서 최근 한옥주택 및 한옥주거단지에 대한 사회적 관심이 증대되고 있다. 기존에 한옥이 밀집한 지역을 중심으로한 정비사업 뿐만 아니라, 대규모 택지개발지구등에서도 한옥주택과 주거단지 개발에 대한 시도가 이루어지고 있지만, 본격적인 사업화는 이루어지지 않고 있다. 본 연구는 LH가 공급하는 신도시의 단독주택용지와 특성화용지등을 대상으로 하여 한옥의 잠재적 수요계층을 바탕으로 사업모델을 도출하고 사업모델에 대한 타당성을 검증하여 향후 사업화를 위한 방향을 제안하고자 한다. 기존에 검토되었던 고급형 타운하우스 형태의 한옥주거단지는 입지선정, 수요불일치 등으로 인하여 사업성이 부족한 것으로 분석되었으며, 설문조사 결과등을 바탕으로 계획규모변경, 용도혼합, 필지세분화등의 방법을 통해 사업유형을 6가지로 설정하였다. 사업모델 중에서 가장 사업성이 높은 유형은 블록형 집합주택으로, 이는 규모의 경제법칙(Ecnomy of Scale)에 따른 건축연면적의 증가가 분양수입의 증대로 이어진 것으로 이해할 수 있다. 소규모 한옥과 근생시설이 결합한 공동주택 모델의 타당성도 높게 나타났으며, 블록형 집합주택과 같은 동일한 사업조건을 적용한다면, 한스타일 공동주택의 사업성이 높은 것으로 분석되었다. 그 밖에 블록형 단독주택지내 고급주택 모델은 민간부문이 일반적으로 추진하고 있는 대표적인 사업유형으로서, 1호당 건설비용이 9.1억원으로 가장 많은 비용이 투입되는 것으로 나타났다. 한옥주거단지 사업성 제고를 위해서는 입지선정, 수요계층의 다양화, 주택규모의 적정화, 용도혼합등을 통한 집합화가 필요할 것으로 판단된다. 또한 단독주택용지에 한옥주택을 도입하기 위해서는 기존의 필지계획의 조정과 분할이 필요하며, 한옥형 용지등의 공급을 통해 새로운 수요에 대응하는 전략도 제안될 수 있다. 또한 기존의 획일적인 택지개발방식에서 벗어나 기초인프라(간선도로 및 상하수도)외에 조성되지 않은 자연상태의 토지인 원형지(原形地) 공급을 통한 개발방식도 검토할 수 있으며, 한옥의 지붕 및 가구구조상 1~2층 이상의 건축이 불가능하므로 경사지 형태를 갖는 원형지 공급방식의 단지조성이 토지비절감, 경관효과 등을 감안할 때 적합한 모델로 제안될 수 있다.

There are similarities between Korea and Japan in terms of national planning and development system and housing policies. Japan has suffered from great shifts of social and economic systems due to skyrocketing land prices for three times and the collapse of the bubble economy after the Second World War. The study reviews historically important changes in the national territory and housing policies for last 60 years in Japan. It also investigates changing trends and characteristics of many socioeconomic indicators with regard to population, housing and other fields in response to these policies. First of all, Japan has experienced significant economic growth before and after the 1960's, and the era of national rebuilding projects in the 1970's. After then, the period of the bubble economy has emerged since 1980; however, it suffered from skyrocketing land values between the late 1980's and the early 1990's, and the collapse of Japanese bubble economy in the early 1990's. In response, many urban regeneration policies and projects were proposed to recover the national economy since 2000. It is found that these national territory development and housing supply policies throughout the country have been influenced by the changing characteristics of social and economic conditions. Since the housing supply ratio in 1968 reached up to around 100% on average, Japan has been focusing attention to improving the residential and living quality for existing housing stock rather than supplying new housing units through large-scale new town projects. These experiences are full of helpful suggestions for our future housing and urban regeneration policies as we reach to more than 100% of housing supply ratio on average.
