  • Cool roofs are currently being emerged as one of important mechanism to save energy in relation to the building. It is specifically proposed that the changing trends of rooftop surface temperature in the flat roof building model could be used effectively as an indicator to reduced cooling load reduced by cool roof since it can present stable temperature record, that is not influenced according to the nearby physical as well as human variables. The temperature of cool roof in summer was lower around $20^{\circ}C$, compared to the general roofs. Such a seasonal or daily comparative study for rooftop temperature in the building model will highlight that the cool roof efficiency could be calculated in much area-wide context according to rooftop color distribution in urban residential area. It is anticipated that this research output could be used as a valuable reference in identifying energy saving by cool roof since an objective monitoring has been proposed based on the rooftop temperature in the building model, fully quantitative performance of thermal infrared image.

  • The urban microscale wind field around the air quality monitoring station was investigated in order to check how a building complex influences it. For this study as the high density areas Jwa-dong and Yeonsan-dong monitoring sites in Busan were chosen. As the direction of inflow which is perpendicular to the building of the monitoring station was expected to cause the considerable variation of the wind field, that direction was selected. The model Envi-met was used as the diagnostic numerical model for this study. It is suitable for this investigation because Envi-met has the microscale resolution. After simulating it, on the leeward side around a building complex the decrease of flow velocity and some of vortexes or circulation area were discovered. In addition, on the edge of the top at the building and at the back of the building the upward flow was developed. If the sampling hole of monitoring site were located in this upward flow, it would be under the influence of upward flow from the near street.

  • The purpose of this study is to analyze and evaluate the 3 types of indoor ventilation methods such as natural, mechanical, and hybrid ventilation in high-rise building which is affected by stack effect and outdoor air pressure. For the evaluation of the ventilation capacity, CFD simulation was performed in a typical high-rise residential building. The results of the simulations are as follows: 1) Natural ventilation method is not enough to the regulation. 2) In case of mechanical ventilation, congested area is occurred but meets the regulation. 3) In case of hybrid ventilation with stack effect, all the areas of indoor meet the regulation and congested area is reduced. 4) In case of high-rise building, the differences of ventilation rate among houses in the building are not large because the mechanical ventilation is main factor.

  • Recently, the use of renewable energy has been increasing to achieve carbon neutrality. The concept of a zero-energy building is also attracting attention. In this study, a preliminary study was conducted to analyze the feasibility of a hybrid wind and solar power generation system between buildings that utilize the building wind generated by the Venturi effect. For this purpose, the wind speed and sunshine hours were monitored in the area where the building wind blows by the Venturi effect, and the power generation depending on system types, areas, and season was estimated. Consequently, the wind power generation system showed a larger amount of power per area than solar power. The wind power systems can generate larger power if wind power blades are installed along the height of the building. As a preliminary study, this study verified the feasibility of the system utilizing building wind and suggested follow-up studies.

  • The border area between the South and North Korea is considered a stage for promoting Green Détent through the transformation of the Demilitarized Zone into the Green Peace Zone. This paper proposes 'Prosuming-index' composed of items to evaluate the multi-layered nature of industrial and infrastructure projects in the ecological and environmental fields planned in the border area. Based on the prosuming-index, we derived the following four types of potential for Green Detent practice in the border area-first, the Incheon and Ganghwa regions as 'a logistics/human network and agricultural/fishery production area', second, the northern Gyeonggi region as a 'cooperative network area based on the smart technology industries', third, the western Gangwon and the parts of nothern Gyeonggi region, as 'a multiple prosumer's area based on carbon neutral technologies', lastly, the eastern Gangwon region, as 'a transition area from idle or aged infrastructure to green infrastructure through the renewable energy industries'.

  • The Municipal Building of Busan was the first western-style building of Korea in 1879. It was also the predecessor of Busan Metropolitan City Hall. On the other hand, the Municipal Building of Busan was a symbolic structure that shows the history of Busan. The Municipal Building of Busan has inherited the construction location and site, including the speciality of Choryangwaegwan, and is a good example of the process of inheriting the authority of the former space through the appropriation of the building. The Municipal Building of Busan was relocated to the edge of the coast in 1934 because a small and dilapidated building failed to function properly. The relocation of the Municipal Building of Busan in 1934 was the origin of changing the coastal space in downtown. As a result, landfill sites along the coast were in the limelight and developed into the downtown area of Busan after Korea's liberation.

  • The IB is normally defined in terms of BA, OA, security system, information processing and telecommunications services However, the buildings being already in existence are deficient in two areas. One of these areas is building envelope and plan. The other area is mechanical, electrical and structural systems which do not provide the environmental quality required by IB. Existing technology and design knowledge are available to address these deficiencies. Especially, the office buildings being already in existence must meet IB requirement in order to achieve desirable office environment. They are a building envelope, moisture control, properly-located windows, shafts for duct, telephone and electric closets and acoustical environments. In this paper, a new approach to construct the work scope of remodelling the office building being already existence is described by contrasting the building performance criteria of IB. It concludes by speculating on the consequences of extrapolating the results of study to remodelling the office building being already existence.

  • This study aims to analyze the changes (2011→2021) in social and environmental factors, such as actual construction activities, including building development and officially assessed individual land price, of the areas that have been released from the park during the second national park area adjustment period (2010~2011) and compare them with those of the areas that retained parks in the same period to analyze the development impact. In the released area, a building has been constructed per 16,431 square meters since 2011. Moreover, both the number of floors and height of the building has increased, and it was analyzed that the class 2 neighborhood living facilities occupied the highest proportion of the building use. Officially assessed individual land prices increased by 42.3% in the released area and 38.6% in the retained area. The analysis by region showed that the officially assessed land price increased by 55.2% on average in both released and retained areas in Seoul and 9.4% in Gyeonggi-do, indicating a much larger increase in the Seoul region. The issue of private property rights in national parks was mostly resolved as they were released through the second national park area adjustment. However, the Korea National Park needs to promote the benefits of landowners by suggesting rational alternatives such as adjustments to the park zoning and facility planning.

  • The exterior color of the building reflects its style. With the advancement of the 'Village Art' project in South Korea, many villages have gradually developed into tourist attractions. Therefore, it is also important to distinguish between residents' lifestyles and tourist needs through architectural color design. This article first investigates the literature and analyzes the use function of the building and the role of the exterior color in the villages. Secondly, the four types of buildings in Huinnyeoul Culture Village: residential, commercial, leisure, and public toilets are investigated as the research objects. Analyze through the KSCA color measurement analysis system and questionnaire survey, and propose a color plan for the exterior of the building. Research results: First, the main color area of the outer wall of the residential building should be the largest, with a tendency of high brightness and low saturation. Second, small buildings with high chroma in the recreation area can be used as visual guidance.Third, the buildings in the commercial area are mainly of high brightness, high chroma, and multi-hue. Fourth, the main color of the bathroom is the main color of the residential area and the leisure area, which can provide a sense of visual stability.
