This study is to find the effective way to green perpendicular wall spaces as soon as possible and to get basic data for activating the perpendicular greening on high story building through the experiment of container-type planting ground in which lightened artificial soil mixed with rock wool was put. Comparative studies of the sizes of containers and soil were carried out but separate management was not performed. Four plants(Euonymus fortunei var. radicans, Lonicera japonica, Parthenocissus quinquefolia, Parthenocissus tricuspidata) which have the capability to cover and screen perpendicular spaces were used in the experiment. In result, a container must be equipped with over 15cm depth soil mixed with less than $30\%$ of rock wool.

The purpose of this research is to suggest the planting methods and the reasonable target levels of IGS for promoting green streetscape in Seoul. Using the three dimensional computer simulations, various greening methods were applied to evaluate effectiveness of promoting green streetscape. The results of this study suggest that promoting tree planting on car lane is more effective than on pedestrian side walks. In wide streets, the height of tree has positive effects on promoting green streetscape. In both car lane and pedestrian side walks, the greening effects of tree planting both in zig-zag pattern and in parallel pattern were similarly most high. The width of strip in side strip planting has positive effect on promoting green streetscape. Promoting stratified planting is very effective. Promoting greening wall on pedestrian side walks is more effective than on car lane. Combined the results of IGS survey with the public officials and complex simulations, suggest that the optimal levels of IGS is ranging from 12.0% in alleys to 54.0% in car lanes among arterial roads.

도시는 건축물의 과밀화로 지표면과 함께 녹지의 면적 또한 점차 줄어들고 있으며, 도시기후와 도시생태계에 악영향을 미치고 있다. 그러나 녹지의 중요성은 점차 증가하고 있으며, 지표면과 함께 수직면을 활용한 벽면녹화의 중요성도 커지고 있다. 하지만 방위와 관련된 국내 벽면녹화 지침과 제도에서 방위별로 식재를 제한하는 경우가 있음에도 불구하고, 연구를 통해 실제 8방위별로 식물의 생육 차이가 있는지 알아본 연구는 전무하였다. 따라서 본 연구는 실제 벽면녹화를 도시에 적용하기 위해 방위별 식물생장 특성을 비교분석하였다. 실험은 2020년 5월부터 9월까지 진행하였다. 우선, 8방위 벽체 3개를 제작하여 담쟁이덩굴(Parthenocissus tricuspidata), 송악(Hedera rhombea), 금빛줄사철(Euonymus radicans cv. Aueonmarinata Rehd) 식물3종을 각 벽체에 식재 후 주1회 온도, 조도, 식물의 길이를 측정하였다. 연구결과, 담쟁이의 경우 북향에서 생육이 왕성하였고, 송악과 금빛줄사철은 남향에서 생육이 왕성하였다. 식물 3종 모두 6-7월에 생육이 왕성하였으며, 담쟁이는 초장생육이 왕성하였고, 8월에 모든 벽면을 100% 피복하였다. 송악은 초장생육속도가 낮았으며, 피복률 또한 평균 45%로 낮게 나타났지만, 식물3종 중 지표면의 피복률은 송악이 가장 높았다. 금빛줄사철은 초장생육속도가 낮았으며, 최종적으로 북, 북서향을 제외한 벽면을 100% 피복하였다. 벽면녹화에 사용되는 모든 식물이 동일하게 생장하지 않으며, 방위로 인한 영향보다 식물 생육 특성에 따라 생장 차이가 있다는 것을 알 수 있었다. 따라서 식물생육의 특성을 파악하여 방위별 알맞은 식물을 식재하는 것이 좋을 것으로 판단된다.

Importance of energy consumptions has being emphasized because of problems of the energy and environment. So, recently, green wall systems have been installed to reduce building energy consumptions. The green wall systems provide several benefits; they make it possible to maintain moderate thermal comforts by greenery. Greening such a surface wall in the building by plants, the temperature of the wall can be properly controlled that purifies the air and improves the view spanning over the space. This study evaluated the effects of green wall systems on reducing room temperature quantitatively, changing of humidity, decreasing of $CO_2$. Test results were confirmed; first, the space installed by green walls showed that temperature and $CO_2$ decreased and humidity was increased. Second, two structures were compared with the solar radiation, and green wall systems controlled the temperature and humidity stably near the wall regardless of the amount solar radiation. In conclusion, the green wall systems can contribute to thermal comforts and indoor air quality in the buildings.

The purpose of this study was to analyze the design trend of the vertical garden design in the indoor space through the examples of green wall in the lobby space. For the analysis, this study looks into the 'Guide for the Building Greening System' to understand the technical consideration for the green wall. After that, the key design elements was drawn from existing green walls through the literature review and field survey and field-survey. The study picked six green walls which was completed after 2000 in the lobby space in Seoul. The major findings of this study were as follows: First, the design factors mainly depend on the plant selection, which leads to the outlook and texture of the vertical walls. The texture is expressed by the two-dimensional or three-dimensional planting methods which is related to the selection of plant species. Second, the vertical walls in the lobby area should be planned for the function of space which could be transition, human traffic, mood and attraction. Third, the vertical wall should be integrated with the surroundings in order to reinforces the dynamic or static space experience.

Tropaeolum majus, with a high decorative and food demand for vertical greening systems, has been utilized to revitalize urban agriculture. The effects of number of non-woven fabrics in a non-water environment and the adaptability of T. majus to this system were investigated. Planting ground composition of the container-type wall vertical greening system was made using non-woven fabric in one, two, three, or four layers. The results showed that the soil water content remained the highest when the non-woven fabric comprised 4 sheets. The morphological properties showed more growth with the 4 sheets than with 1, 2, and 3 sheets. In terms of physiological characteristics, chlorophyll content was mostly high in the 4 sheets, while shoot fresh weight value was in the order of 3 > 4 > 2 > 1 sheet, and root fresh weight value was in the order of 4 > 2 > 1 > 3 sheets. The dry weight of the measured values in the shoot was in the order of 4 > 3 > 2 > 1 sheet while no clear difference was found in the root of each treatment. The difference in the flowring characteristics was not different, but in evaluating the characteristics as a whole, the growth in the three layers of non-waven fabric was the best. In addition, the soil moisture contents and the growth characteristics were statistically significant as a positive correlation between the groups. Thus, greater the non-woven fabric, the higher is the adaptability of T. majus to dry stress under soil water-free conditions by maintaining soil moisture content. This showed that it represented an effective alternative as a method of vertical greening system for lower maintenance urban agriculture.

Due to the rapid process of industrialization the cities of Korea confront changes of climate, destructions of the habitate and decrease of the green. Recently Seoul and other local governments have implemented policies and projects to improve the environmental surroundings. In reality, however, those policies and projects face difficulties in the course of implementation. The fact that there are no concrete regulations and specific legal procedures turns out to be one of the main difficulties. The aim of this study is to present specific plans and methods of wall-planting and to provide basic guidelines for the future direction of wall-planting and offer ideas of facilitating wall-planting. This study is based on questionnaires from specialists of landscape architecture through individual interviews and/or e-mails. The questionnaire is consisted of following 4 sections. 1. Show the experts current regulations and/or legal procedures and ask them improvements and suggestions. 2. Ask them choose matters of the highest priority by using Ricardo's diagram method. 3. Ask them to make a graded list in terms of the location and method of wall-planting. 4. Study the maketability of the wall-planting products currently in circulation. The city of Seoul and the Ministry of Environment recommend that trellis and/or planting inducement structures be installed on the building wall by regulation. The specialists responded to the questionnaire advocate that green wall without trellis should be allowed as green zone. Therefore regulations concerning the wall-planting should be determined specifically according to the characteristics of individual plants and walls. It has been urged that legal aid and social support must be reinforced to establish rules dealing with wall-planting. The respondents also point out that significant cutting down of the tax is far more effective in accelerating the wall-green instead of administrative support. The highest priority in terms of planting has been given to sound-proof wall, retaining wall and building wall. Concerning the maketability of the wall-planting products, panel products are recommended for early-planting and building planting. It has been suggested that the research and study of new materials and species be done in advance.

This study was conducted to investigate the response of the human body to stress induced by wall recording of subway stations in the city center. The experiment was conducted as a simulation exercise, and six images were selected and produced based on Subway Line 2, a representative underground space in Seoul. The study participants included 24 male and female college students. A three-minute experiment was conducted, during which the participants were shown the control image and green wall image once each. To measure psychological status, the following measurement indicators were used: Semantic Differential, Positive Affect and Negative Affect Schedule and State-Trait Anxiety Inventory. Physiological changes were investigated by tracking participants' heart rate and blood pressure. Results showed that parasympathetic and sympathetic nerves were activated in the presence of the green wall in the subway station. The psychological evaluation analysis revealed that negative affect toward underground space decreased, while positive affect increased. This study found that the green wall in subway stations has a stable effect on the human body, both psychologically and physiologically. In the future, green walls in underground spaces can be used to reduce psychological stress and increase physiological relaxation.

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.
