Evergreen Giraffe Grass Bag Method: Weed Prevention and Soil Erosion Prevention Rooftop Greening System

basic information

The Evergreen Kiriin-so Bag Method® (FTM Bag) is an innovative rooftop greening system that utilizes a zipper-type planting bag, unlike anything seen before. It is a triple intellectual property product consisting of the bag method (Patent No. 4911418 + Registered Trademark No. 6125712) and variety registration (Variety Registration No. 15866). The triple intellectual property of the Evergreen Kiriin-so Bag Method (patent, trademark, and variety registration) leads to a successful rooftop greening solution. 1. Prevents the intrusion of weeds 2. Prevents soil runoff 3. Easy installation with a zipper The standard size of the bag method is 50 cm square, with a wet weight of 13 kg per bag. There is also a rectangular type measuring 15 cm x 100 cm available. Grommets are included, and custom sizes can be ordered. The bags are made of root barrier sheets, preventing the intrusion of weeds and the scattering and runoff of soil. The bags allow the Evergreen Kiriin-so to provide moisture to the soil while simultaneously preventing soil dryness. The site will receive bags filled with soil and seedlings of Evergreen Kiriin-so, so you simply open the zipper of the bag, insert the seedlings, and close the zipper. This is a simple greening system that completes the greening process by just arranging the bags containing the plants.

  A fail-proof rooftop greening system "Evergreen Kirinsou Bag Method" case study: Rooftop greening This is a 720 square meter rooftop greening (for a self-propelled multi-story parking lot) using the fail-proof rooftop greening system "Evergreen Kirinsou Bag Method." The parking spaces on the rooftop are being greened. If the number of cars increases in the future, it is considered that the greening can be reverted back to parking spaces. With the "Evergreen Kirinsou Bag Method," the greening areas can be easily relocated. Soka Matsubara Danchi was a UR rental housing complex developed by the former Japan Housing Corporation located in Soka City, Saitama Prefecture. Occupancy began in 1962, and at the time of completion, it was said to be the largest scale in the Orient. Due to aging, a rebuilding project is being carried out sequentially.

  A fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method" case study: Roof greening This is roof greening using the fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method." Since it is on the roof surface, it is secured with a scatter prevention net. The Asakusa Culture and Tourism Center is a tourist information facility located in Taito Ward, in front of the Kaminarimon Gate. The first floor features an information counter and currency exchange services in Japanese, English, Korean, and Chinese, while the second floor has a tourist information corner. The top floor, the 8th floor, is a free observation terrace. Due to the existing building being over 50 years old and deteriorating, a competition was held in 2008, and the proposal by architect Kengo Kuma was adopted. The initial plan had a height of 41.25 meters, but voices of opposition arose from Senso-ji Temple and the local shopping district, claiming it would disrupt the harmony of the streetscape, leading to a reduction of about 2 meters, resulting in a height of 38.9 meters. In 2012, it received the Good Design Award. For more details on the fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method," please visit https://kirinsou.jp.

  Failure-proof rooftop greening system "Evergreen Kirinsou Bag Method" case study: Slope greening A sediment control dam (sabouentai) is a type of dam installed on rivers. It is also referred to as a "sediment control dam." This facility captures harmful sediment such as debris flows that flow down from upstream and gradually releases the accumulated sediment, thereby regulating the amount of sediment flowing downstream. By accumulating sediment in the sediment control dam, the slope of the river becomes gentler, preventing the riverbed and riverbanks from being eroded, while also weakening the destructive power of debris flows. Additionally, it helps stabilize the foothills on both sides, preventing landslides on the mountain slopes. However, the construction of large concrete walls in mountainous areas can lead to landscape issues. Until now, greening on sediment control dams has been difficult, and maintaining that greening has also been challenging. The Evergreen Kirinsou Bag Method has made it possible to easily achieve greening. The greening of sediment control dams blends well with the surrounding scenery.

  Evergreen Kirinsou Case Study: Solar Sharing + Greening Solar sharing refers to the initiative of installing solar panels on supports erected in agricultural land to regulate sunlight and share solar energy between agricultural production and electricity generation. The Ministry of Agriculture, Forestry and Fisheries refers to this power generation equipment as "agricultural-type power generation equipment." By effectively utilizing the upper space of farmland while continuing agricultural activities, it is possible to generate electricity, which supports agricultural management. Furthermore, it is also expected to contribute to the regeneration and reuse of increasing abandoned farmland. Evergreen Kirinsou is being produced under the solar panels. The Evergreen Kirinsou cultivated here is actively used nationwide for rooftop greening, wall greening, and slope greening.

  Fail-proof Rooftop Greening System "Evergreen Kiri Grass Bag Method" Case Study: Rooftop Greening (Rooftop Greening by Middle School Students) The students themselves carried the materials to the rooftop, planted them in bags, and arranged the bags to complete the rooftop greening. The photo below was taken as a graduation memorial. This rooftop greening project was led by the school's science club. The science club measured the temperatures of classrooms that were not greened and the classroom directly below the rooftop greening, using thermography to investigate the temperature distribution in the classrooms. In the classroom directly below the rooftop greening, the overall temperature was shown in blue, confirming the effectiveness of the rooftop greening.

  Fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method" construction example: Rooftop greening (also accommodates curves) This is a rooftop greening project of approximately 180 square meters using the fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method." The rooftop greening area is divided into buildings A to D, and the shapes are not rectangular, with curved sections present throughout. This cannot be accommodated by conventional tray-based greening. The Evergreen Kiri Grass Bag Method was adapted using square bags of 50 cm, 25 cm, and rectangular bags of 15 cm x 50 cm. Since the bags have flexibility, they can be shaped on-site to fit the contours. Additionally, custom sizes can be ordered, allowing for rooftop greening tailored to the site. The flexibility of the bags also enables greening on curved surfaces.

  Fail-proof rooftop greening system "Evergreen Kiri Grass Bag Method" construction example: Slope greening Using the Evergreen Kiri Grass Bag Method, we implemented greening with letters as a landmark for the interchange. Evergreen Kiri Grass is resilient to heat, cold, and drought, making it a low-maintenance plant. It replaces its new shoots around November, ensuring that it does not grow excessively and change the shape of the letters. The bag method is made with weed control sheets, preventing weed intrusion and soil erosion. With this combination of low-maintenance plants and the bag method, it is possible to create such lettering through a greening system.

  Fail-proof Rooftop Greening System "Evergreen Kiri Grass Bag Method" Case Study: Rooftop Greening (Renovation of Existing Greening) This is a renovation project for the existing rooftop greening on the 5th floor of a 10-story apartment building shaped like a "U" with a courtyard. The original rooftop greening was done with sedum, but it had become overrun with weeds, causing issues. The request was to renovate while preserving the existing parts. The shape of the building resembles a pyramid, making it a challenging site for transporting materials. Since cranes could not be used, all materials were handled manually, and they were brought in using an emergency escape hatch. After removing the surface weeds, a treatment to prevent weed germination was applied. Subsequently, a weed barrier sheet was laid down, and greening was carried out using the Evergreen Kiri Grass Bag Method.
