Green facade has a significant impact on building's energy performance by controlling the absorption of solar radiation and improving outdoor thermal comfort through shading and evapotranspiration. In particular, since high-density building does not enough green space, green facade, and rooftop greening using artificial ground plants are highly utilized. However, the level of cooling effect according to plant traits and irrigation control is different. Therefore, in this study, the cooling effect analyzed for a total of 4 cases by controlling the irrigation condition based on hedera and spurge. Although hedera under sufficient water had the highest cooling effect(-2℃~-4℃), had the lowest cooling effect under non-irrigation(+1.1℃~+4.4℃). In addition, hedera under sufficient water had cooling effect than hedera under non-irrigation(-1℃~-8.1℃) and in the case of spurge, it had cooling effect(-0.3℃~-7.8℃) more than non-irrigation. As a result of measuring the amount of transpiration according to the light intensity (PAR) and carbon dioxide concentration conditions, transpiration of hedera was higher than the spurge (respectively 0.63204mmolm^-2s^-1, 0.674367mmolm^-2s^-1). The difference in the cooling effect of the green facade under irrigation condition was significant. But the potential cooling effect of green facade according to plants species was different. Therefore, in order to maximize and continuously provide the cooling effect of green facade in urban areas, it is necessary to consider the characteristics of plants and the control of water supply through the irrigation system.

Within green facades, the greening side of the wall is first recognized by people, leaving a visually lasting impression. As facades play a crucial factor in forming street image, their design can be considered most important. In modern days, 'patterns,' one of the popular elements of design, has developed into becoming a method of expressing architects' emotions or images as well as ways of seeking satisfaction. As opposed to recent overseas movement where patterned green facades have been widely utilized, the domestic trend still remains in outdoor green facades without patterns. This study, focusing on overseas patterned green facades, classifies the facade pattern's expressive methods into two greater parts, and four categories. Furthermore, among the elements and properties from Biophilic pattern guidelines, we specifically focus on 'Repetition Pattern,' which corresponds to 'Complexity & Order.' Biophilic design has the notion of pursuing an environment that aids modern people's comfort and well being. Providing information on patterned green facades that have largely gained popularity, this study also presents its aesthetic directions that may be applicable domestically in the future.

도시가 산업화 되어가면서 도심의 토지이용이 과밀화되고 건축물의 면적이 늘어나고 있다. 이에 건축물 녹화가 옥상 및 벽면을 중심으로 적극적으로 조성되고 있으며, 입면녹화의 경우 건물이 고층화 되면서 입면적이 넓어 벽면녹화가 도심에서 효과적인 녹화수단으로 인식되고 있다. 특히 패널타입의 녹화수법은 조기 녹화와 설치 시공의 편리함으로 점차 이용이 증가하고 있다. 그러나 패널타입에 대 한 연구는 대부분 식생 하부 시스템이나 관수시스템을 중심으로 이루어지고 있으며, 경관 중심에 대한 연구는 전무한 실정이다. 이에 본 연구에서는 패널형 입면녹화의 경관평가를 통하여 선호요소를 추출하고자 한다. 설문은 패널형 입면녹화가 설치된 장소의 이용자들을 중심으로 직접조사를 하였다 연구 결과, 자연스럽다는 형용사에서 3.80으로 가장 높은 점수를 나타났다. 이는 옹벽이나 건축물 벽면이 드러나는 것보다 녹화를 하는 것이 이용자들에게 긍정적인 반응을 보이는 것으로 사료된다. 다음으로 친근한(3.70), 편안한(3.65), 아름다운(3.65), 안정감 있는(3.50)가 긍정적인 경관이미지로 나타났다. 반면 정적인, 적막한, 소박한, 무거운, 우중충한, 어두운, 지저분한의 부정적 경관 이미지가 나타났는데, 이는 관리가 제대로 이루어지지 않기 때문으로 사료된다. 이러한 연구 결과를 통하여 패널형 입면녹화의 개발과 보급에 필요한 기초자료로 활용하고자 한다.

The study was conducted to present the criteria of plant selection and planting design pattern suitable for the vegetation blocks which are becoming more popular for the facade greenery in urban areas. The main results are summarized as follows. 1. Under irrigated conditions, the plant grew better than that of unirrigated conditions and herbs grew better than shrubs. In selection of shrubs, it would be more proper to consider the size and depth of the pockets. 2. Under unirrigated conditions, Sedum middendorffianum and foreign sedums grew well, so it can be concluded that sedums can grow at low management condition. And, Hosta longipes and Aceriphyllum rossii could be survive at low management conditions only if irrigation was conducted at dry season. But, shrubs needed irrigation management for survival at vegetation blocks. 3. The results of this study, it can be concluded that greenery of walls and retaining walls might be effective for the creation of green space, improvement of urban landscapes, and the creation of diverse biotopes in urban areas with vegetation blocks.

Laboratory buildings with specialized equipment and ventilation systems pose challenges in terms of efficient energy use and initial construction costs. Additionally, lab spaces should have flexible and efficient layouts and provide a comfortable indoor research environment. Therefore, this study aims to identify the correlation between the facade of a building and its interior layout from case studies of energy-efficient research labs and to propose passive energy design strategies for the establishment of an optimal research environment. The case studies in this paper were selected from the American Institute of Architects Committee on the Environment Top Ten Projects and Leadership in Energy and Environmental Design (LEED) certified research lab projects. In this paper, the passive design strategies of space zoning, façade design devices to control heating and cooling loads were analyzed. Additionally, the relationships between these strategies and the interior lab layouts, lab support spaces, offices, and circulation areas were examined. The following four conclusions were drawn from the analysis of various cases: 1) space zoning for grouping areas with similar energy requirements is performed to concentrate similar heating and cooling demands to simplify the HVAC loads. 2) Public areas such as corridor, atrium, or courtyard can serve as buffer zones that employ passive solar design to minimize the mechanical energy load. 3) A balanced window-to-wall ratio (WWR), exterior shading devices, and natural ventilation systems are applied according to the space programming energy requirements to minimize the dependence on mechanical service. 4) Lastly, typical laboratory space zoning categories can be revised, reversed, and even reconfigured to minimize the energy load and adjust to the site context. This study can provide deep insights into various design strategies employed for construction of green laboratories along with intuitive arrangement of various building components such as laboratory spaces, lab support spaces, office spaces, and common public areas. The key findings of this study can contribute towards creating improved designs of laboratory facilities with reduced carbon footprint and greenhouse emissions.
