basic information
This is a rooftop greening product that overcomes the causes of past failures and issues in rooftop greening. It utilizes a zipper-type planting bag method with evergreen sedum (FTM bag). This bag method (Patent No. 4911418 + Registered Trademark No. 6125712) is a triple intellectual property product with a variety registration (Variety Registration No. 15866). The triple intellectual property of the evergreen sedum bag method (patent, trademark, and variety registration) leads to successful rooftop greening. 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. Grommet options and custom sizes are possible. The rectangular type is used for wall greening and folded roof greening. The bag is made of root barrier material, preventing the intrusion of weeds and stopping soil scattering and runoff. The bag allows the evergreen sedum to provide moisture to the soil while simultaneously preventing soil drying. The site will receive bags filled with soil and seedlings of evergreen sedum, 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 by just arranging the bags with plants.

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many instances of damage from typhoons, heavy rains, floods, and landslides across various regions. Additionally, in recent years, there have been widespread heatwaves. In fact, Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Moreover, not only the rise in temperatures but also the extreme drops in temperatures during winter have become one of the abnormal weather patterns seen in recent years. Amidst the increase in such weather phenomena, various problems have also arisen in rooftop greening.

Causes of Rooftop Greening Failures: Selection of Plants Unsuitable for Rooftop Environments Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Additionally, not only are temperatures increasing, but extreme cold and heavy snowfall in winter have also been seen in recent years. As such, rooftops are increasingly exposed to harsh environments, making the selection of appropriate plants essential.

Causes of Rooftop Greening Failures: Weed Issues in Rooftop Greening Systems One of the causes of rooftop greening failures is the "weed problem." Typically, rooftop greening systems have soil exposed on the surface, allowing weed seeds to enter from the surrounding environment, through animals bringing them in, or being carried by the wind, leading to an overgrowth of weeds without notice. Special care is needed for greening roofs of factories or other areas that are not frequently accessed by people.

Causes of Rooftop Greening Failure: Maintenance Issues in Rooftop Greening Systems One of the causes of rooftop greening failure is "maintenance issues." Rooftop greening is not maintenance-free. There are various tasks such as weeding, pruning plants, watering, and cleaning around drains. Initially, it is manageable, but over time, due to reasons like becoming cumbersome or troublesome, it can be neglected and become overgrown. It is necessary to consider the introduction of rooftop greening systems that take maintenance into account.

Causes of Rooftop Greening Failure: Malfunction of Irrigation Systems in Rooftop Greening Systems One of the causes of rooftop greening failure is "malfunction of the irrigation system." To reduce the hassle of watering, automatic irrigation systems are introduced, but it is essential to keep in mind that malfunctions can occur. This is particularly critical for corporate rooftop greening, where the irrigation system may fail during summer vacations when no one is present, leading to the complete destruction of the greening area upon return. Just having an automatic irrigation system does not guarantee peace of mind. When considering rooftop greening, it is also necessary to explore systems that do not require watering.

Causes of Rooftop Greening Failures: The Difficulty of Rooftop Greening Renovations (Waterproofing Renovations) When performing waterproofing renovations, it is necessary to remove the rooftop greening. This removal of rooftop greening becomes a very challenging task. The removal of soil requires a lot of effort and also raises issues related to dirt. Additionally, in the case of tray systems, they are securely fixed (with bolts or adhesive) to prevent scattering. This dismantling work becomes very labor-intensive. Furthermore, when restoring the rooftop greening, there may be cases where reuse is not possible, so caution is needed. It is also necessary to consider rooftop greening that makes waterproofing renovations easier.

Causes of Rooftop Greening Failures: Soil Erosion Issues in Rooftop Greening Systems One of the causes of rooftop greening failures is "soil erosion and scattering." Recently, abnormal weather has increased, with "intense rain" of over 80mm per hour rising by about 1.7 times in the last 30 years. Such heavy rain can wash away the soil and plants in rooftop greening, causing problems like clogging drainage systems. Additionally, recent typhoons have become more powerful, necessitating consideration of scattering due to wind.

Soil Erosion Experiment One of the causes of the failure of rooftop greening is "soil erosion." We recreated heavy rain by bursting large water balloons and conducted an erosion experiment comparing the rooftop greening systems "bag method vs. conventional method." Recently, extreme weather has increased, and the occurrence of "intense rain" with rainfall amounts exceeding 80 mm per hour has increased by about 1.7 times over the past 30 years. Such heavy rain can wash away the soil and plants from rooftop greening, causing issues like clogged drainage systems. For a video comparing soil dispersion experiments, please visit https://kirinsou.jp/system/#experiment1.
-
Soil Dispersal Experiment One of the reasons for the failure of rooftop greening is "soil dispersal." We conducted a dispersal experiment comparing the rooftop greening systems "bag method vs. conventional method" by creating strong winds using a blower and a circulator. Recently, it has been predicted that there is an increasing trend in the occurrence of very strong tropical cyclones, with maximum wind speeds over 45 m/s due to abnormal weather. In such severe weather, the soil and plants from rooftop greening can be dispersed, causing problems such as clogging drainage systems. For a video of the soil runoff comparison experiment, please visit https://kirinsou.jp/system/#experiment2.

Company information
In manufacturing, there are people, and in projects, there is drama. The "passion" of three individuals transcends the boundaries of the company, leading to "co-creation" and "hope." In April 2007, at an exhibition, a project team was born. They wanted to create new solutions originating from the field to solve customers' problems. Three professionals who shared such passionate thoughts met, and the Evergreen Kiri-Sou Promotion Association was established. Professionals in plants, architecture, civil engineering, and facilities breathe new life into the city. Moments of inspiration are continuous. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because of the increase in fakes and deceptions. We aim to remain professionals involved in plants, architecture, civil engineering, and facilities, and we operate the Evergreen Kiri-Sou Promotion Association. The professionals have developed new greening methods and greening systems. That is the Evergreen Kiri-Sou bag method.
