Recently, energy recovery ventilators (ERVs) have been installed for energy saving in many multi-residential buildings in Korea. The performance of the heat exchanger of an ERV is analyzed in this study under specific indoor and outdoor conditions in a test-cell measurement. However, the performance of the heat exchanger varies according to the indoor and outdoor condition. In this study, the performance of energy recovery of the ventilation system was therefore analyzed in actual weather conditions using field measurement. Experiments were conducted under winter conditions in a multi-residential building for 20 days. Based on the measurement results, the characteristics of sensible heat and latent heat exchange rates were analyzed.

The actural condition of rural house polts, houses and their attached facilities was surveyed in CHUNGCHEONGBUK-DO in order to find out existing residential problems. From the data collected, general influencing factors, housing/residential environmental qualities, and farmer's opinion on them were analyzed or obtained as the basic design criteria for future projects. The structural shape of rural housing should be developed on the basis of our traditional one. The materials of wall should be made from soil sourced one. Kitchin room and rest room should be improved in view of the Western style. Residential space should be harmonized our traditional one(reception of a guest preferred) with westernized living space(nuclear family life preferred). The plane planning of 'ㄷ' type would be generally preferred in the block planning of rural housing and attached facilities. Livestock pens and compost houses would be seperated from, while storehouses would be coexisted with a living space.

The integrative ecological approaches of chemical assessments, physical habitat modelling, and multi-metric biological health modelling were applied to Gwanpyeong Stream within Gap-Stream watersheds to evaluate environmental impacts on the constructions of residential and commercial complex. For the analysis, the surveys conducted from 45 sites of reference streams within the Gap-Stream watershed and 3 regular sites during 2009 - 2010. Physical habitat health, based on the habitat model of Qualitative Habitat Evaluation Index(QHEI) declined from the headwaters(good - fair condition) to the downstream(poor condition). Chemical water quality, based turbidity and electric conductivity(EC), was degraded toward to the downstream, and especially showed abrupt increases, compared to the values of control streams(CS). Also, concentrations of chlorophyll-a in the downstreams were greater compared to the control stream(CS), indicating an eutrophication. Biological health conditions, based on the Index of Biological Integrity(IBI) using fish assemblages, averaged 19.3 which is judged as a fair condition by the biological criteria of the Ministry of Environment, Korea. The comparisons of model metric values in sensitive species and riffle-benthic species on the Maximum Species Richness Line(MSRL) of 45 reference streams indicated a massive disturbances in all sampling locations. Also, tolerance guild and trophic guild analyses suggest that dominances of tolerant species and omnivores were evident, indicating a biological degradation by habitat disturbances and organic matter pollutions. There was no distinct longitudinal variations of IBI model values from the headwater to the downstream in spite of slight chemical and habitat health gradients among the sampling sites. Overall, integrative ecological health(IEH) scores, based on the chemical, physical, and biological parameters, were low compared to the 45 reference streams due to physical and chemical disturbances of massive constructions of the residential and commercial complex. This stream, thus showed a tendency of typical urban streams which are disturbed in the chemical water quality, habitat structures, and biological integrity. Effective stream management plans and restoration strategies are required in this urban stream for improving integrative stream health.

In foreign countries, the use of containers has already been stabilized with their advantages utilized in various forms. Containers are also utilized in Korea as various forms of architecture, but domestic container buildings have poor public consciousness so as to be limitedly utilized as temporary structures based on economic efficiency. Besides, there is the lack of research and development on them. Particularly, despite the advantages of containers as housing facilities, the use of containers as short- or middle-term temporary housing is limited and does not spread. Also, compared to general housing, containers have lower quality of physical environment and even frequently bring about negligent accidents such as fire and electric shock. Thus, this study intends to identify the actual condition of using container houses, the problems in using them, and the direction of improving their residential environment. For this purpose, it analyzes the present condition and characteristics of domestic container housing, and derives conclusions from the focus group interview with 23 residents who have lived in Seoul and Gyeonggi-do for over a year about such survey items as daylighting, ventilation, privacy condition, water service and sewerage, insulation, soundproofing, view, and room scale.

This research deals with the process of conducting a reinforced concrete slab loading test of a Residential Complex Project at the Shatt Al Arab District which is located in southern Iraq. The purpose of the test which represents a destructive test is to evaluate the structural behavior of the slab condition state during and after the examination of the test process in order to ascertain the ability of the slab ceiling to withstand the loads generated during the use of the building. The test was carried out accordant to ACI 437.2-13 code. The reason for this test is the postponed 8 years of building project construction. Concrete blocks were used to simulate and conduct a loading test of 30-tons for 3 days. The central point has been installed to measure the slab deflection that occurred during the test. The results showed that both the total deflection and residual deflections were lesser than the permissible values according to the ACI 437.2-13, the RC slab behavior was mainly linear structural behave, and that the purpose of the examination was achieved. Finally, a new method was introduced to the assessment of the slab condition at the support which is found in good condition.

Transformations of the urban spatial structure, from sub-area redevelopment to newtown development, results great influences upon existing urban condition and spatial configuration. The purpose of the study is to analyse the effect of the urban spatial configuration of Uijongbu city where experienced changes after newly development of city center and new residential area. The west part of the city where is limited in growth by military bases, ego U.S Army basecamp, were planned and established as the other axis of the city center since mid 1980's. After that new residential area which is located in far east of the city were also developed. Space syntax as a methodology has been adopted to conduct quantitative analysis which is able to interpret differences between sub-areas ; old city center, new city center, new residential area. The results of the analysis are follows ; 1) existing structure of the urban fabric, especially old city center, is sustained and intensified, 2) new city center which is west part of the city has failed to achieve organic spatial connection adjacent to old city center, 3) there is less spatial depecdency relationship between city center and new residential area where is identified as another small self-support city within the city.

There is a growing tendency within old towns to analyze spatial characteristics to initiate various sustainable development programs and systems to make high-quality small-medium local cities. Professional research institutions in Korea are looking for new guidance into making housing regeneration policies and for trying to merge different functions. But there is a lack of research on support indicators and legal systems for residents. The purpose of this study will analyze the support systems and indicators of France for declined residential blocks in urban. Because the government of France have developed the policy for declined housing blocks. And they are establishing support systems to improve the quality of the residential environment and the resettlement of existing residents. First, this research study the condition of declined housing blocks in Paris. Secondly, support systems and policies of PNRU and PNRQAD are investigated and analyzed. Finally, cases by PNRU and PNRQAD are analyzed to derive the strength of this system. As a result, the following implications are derived. 1) the strengthening of social support, 2) the establishment of specialized national institutions and indicators, 3) increasing citizen participation, 4) Sustainable research program for neighborhood regeneration.
