최근 국토교통부에서는 무분별한 재건축, 재개발로 인한 사회적 비용을 감소시키고 주택의 수명을 늘리기 위해 장수명 공동주택의 도입을 촉구하고 있다. 장수명 공동주택은 기존 아파트 건설에 적용되는 벽식 구조와는 달리 기둥과 보가 연속적으로 이루어진 구조이기 때문에 내구성, 가변성, 유지관리 및 리모델링 용이성 등의 장점을 갖는다. 그러나 장수명 공동주택의 경우 기존의 벽식 구조방식의 주택에 비해 초기 투자비가 다소 상승하는 문제가 있는데, 이는 장수명 공동주택의 보급 확산을 저해하는 요소로 작용하고 있다. 이에 본 연구에서는 건물의 총 생애주기 관점에서 기존의 벽식 구조 공동주택과 장수명 공동주택의 경제성을 비교 분석하였다. 연구 결과 장수명 공동주택의 경우 일반 벽식 구조 공동주택에 비해 초기 신축미용은 약 18% 정도 증가하지만, 50년간의 총 생애주기비용을 산정해보면 벽식 구조 공동주택에 비해 약 7% 정도 경제적인 것으로 나타났다. 즉, 장기적인 측면에서 볼 때 장수명 공동주택의 도입이 경제적 사회적 측면에서 충분히 이점이 있음을 알 수 있었다.

Precast Concrete (PC) construction method can be the one that is suitable for long-life housing due to its merit in respect of maintenance and durability based on crack-free from mass production with indirect construction cost-saving-effect due to shortening construction period comparing to the conventional construction method, but it has the problem that causes the raise of direction construction costs. So, this study analyzed its economic feasibility of PC method whose maintenance and durability are excellent for underground parking lot of apartment house for accomplishing cost-saving long-life housing by applying the various structural system. In evaluation of unit module structural system, two-way PC system requires 10 to 28% more costs for frame work than RC rigid frames, and, one-way PC system 98~112%. Although it varies depending on the method, the costs are similar to RC rigid frame structure, provided a proper method is adopted. Also, Model 11, which was most economical in the evaluation, was applied to an real parking lot and about 2 to 6% of construction costs was reduced than RC rigid frames. This seems to be because, although PC system has a higher production cost, introduction of P.S (prestress) reduces member depth and, therefore, height, as well as the number of members per unit module.

Multi-residential housing in Korea has many problems basically because maintenance, management, and remodelling have been done without considering building elapse and residents' needs. Residential open building has been suggested as one of the solutions. Even though the techniques have been actively developed for residential open building in Japan and the Netherlands, some obstacles are still existing. Especially in Korea, due to the lack of studies for facilitating residential open building, the development and popularization of residential open building are delayed. With the concern that the facilitation of process and systems is as important as technical development, the evaluation of process and systems is needed for promoting residential open building. As result, strong investigation of current situation can offer basic foundation to facilitate residential open building. The purpose of this study is to propose plans to facilitate residential open building in Korea through a comparative study between Korean and Japanese system.

The objective of this paper is to suggest structural design for the long-life housing apartment complex to save the construction cost. The key is to use unavailable underground space due to bearing walls or bad configuration of columns in apartments as the parking space. Therefore, the structural plan of apartment buildings considering the parking section in the underground should be designed. After analytical resutls of three cases, it is significant effect in saving construction cost.

This study aims to suggest improvement plans and explain about the current situation for facilitating Long-life housing, based on the results on flexibility items among 27 items consisting the "Housing Performance Grading System". From the 9th of January, 2006 to the month of July in 2011, study has analyzed evaluation results on 216 different types for each grade and reviewed evaluation criteria and methods. Current evaluation criteria applies quantitative analysis, by calculating in percentage how much bearing walls and columns, which hinder flexibility, take up space in the household. The evaluation rate for each household was assessed in relation to its structural system, and a higher grade was given to column-typed structures. In addition, to facilitate long-life housing, this study extracted harmful factors, expanding the range of evaluation. The first step was to evaluate structure, which is the basic element. The second step can to evaluate the probability of applying resources in response to the changes of structural systems. As The third step, Flexibility item will evaluate the probability of moving the water-using area, suggesting gradual approach. Thus, through evaluations of flexibility items, the study aims to improve the quality of life in household, by avoiding uniform structures and acquiring more freedom for space designs.

In Korea, there has been a tendency that multi-family housings are constructed by providers such as constructors or real estate agents for the economical benefits and selling efficiency, using standardized plans, load-bearing wall system, water-based construction method, and uniformized formworks. Especially, the traditional installation works which service equipments are buried into structures cause serious problems such as shortening building life span, increasing times of remodeling during specific period (100 years) and wasting resources. Also the unilateral way of massive distribution by providers for multi-family housings is not appropriate to meet the various social needs of residents. To solve these problems, it is necessary to build long-life housing which can be easily separated installations, interior and exterior finishings from structural parts. Therefore, this paper will examine the present administrative law and the civil law in order to find negative factors that can be obstructions for providing long-life housings and set the direction to revise the regulations.

The purpose of this study is a proposal about the flexibility of the performance category to revitalize the "Housing Performance Grading Indication System". This system consists of 5 main performance parts, 14 performance categories and 20 detailed performance lists. 5 main performance parts are Noise and Acoustics(Light-weight impact sound control, heavy-weight impact sound control, sound control of toilet, sound control of party wall), Long-life(flexibility, remodeling & maintenance, durability), Landscape & Indoor Environment(landscape, formaldehyde control& ventilation, daylighting, thermal environment), Welfare & Barrier-free(playground and community center, welfare space, barrier-free design), Fire Safety(fire safety, safe place, fire-resisting quality). The flexibility of the performance category is conformed to Long-life housing related grading and can realize the Long-life housing in response to resident needs about the space rearrangement. Now, The flexibility of the performance category is limited to the evaluation of the private space, that is, the Skeleton evaluation. This study would suggest alternatives to improve uppermost limits through analyzing 60 examples from January 9th 2009 to October 30th 2008. The flexibility of the performance category is possible to estimate not only the Skeleton evaluation but also the Infill evaluation in response to social changes.

Various problems regarding the wet floor method such as its complicated process and waste of thermal storage have been raised, but the usage of dry floor recommended for long-life housing has declined due to lack of confidence on the performance of dry floor. The purpose of this study is to secure the credibility of dry floor. Under this purpose, this study considered precedent studies and established directions to secure the performance of long-life housing infill, and thus, 9 performance items (Impact sound, Smoothness, thermal comfort, sensation hardness while walking, falling safety, impact resistance, local compression load, local strength and strain at heating) were drawn. In addition, the experiment was carried out for 5 performances except for legal performance, some dry floor performances and whole spatial performance. As a result, an appropriate result from all performances except was obtained. The performance of dry floor was verified for each item from these results and it is expected to use such results as basic data on dry floor in the future.
