Rooftop greening system: Evergreen Kiri grass bag method. What are the causes of failure in rooftop greening?
There are solutions to the causes of plant selection mistakes, rampant weeds, soil erosion, and failures in rooftop greening systems.
"The Rooftop Greening Revolution Begins" Recently, phenomena such as heavy rain and strong winds, which were previously referred to as abnormal weather, have started to become commonplace. The plants used in the thin-layer rooftop greening so far have mainly been sedums, but they are declining due to the recent weather conditions. Additionally, soil is being washed away by heavy rain and strong winds, leading to overgrowth of weeds. "Causes of Rooftop Greening Failures" Please see the detailed information below. Previous rooftop greening systems were complex and could only be handled by specialized contractors. The rooftop greening revolution aims to break away from these existing methods and maintain a green oasis easily and sustainably. The system that has made this rooftop greening revolution possible is the "Evergreen Kiri-so Bag Method®," which ensures successful rooftop greening. "Features of the Evergreen Kiri-so Bag Method" ■ Soil erosion prevention ■ Weed control ■ Easy greening ■ Low maintenance ■ No irrigation needed The Evergreen Kiri-so Bag Method is a new greening approach that puts specialized soil for evergreen Kiri-so into bags, achieving "soil erosion prevention," "weed control," and "easy greening." Search for "Rooftop Greening Revolution" on YouTube to find videos of soil erosion experiments. You can navigate to the video page through the related links below.

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many occurrences of damage from typhoons, heavy rains, floods, and landslides in various regions. Additionally, in recent years, widespread extreme heat has been observed. In fact, Japan's temperatures have been rising year by year, with particularly abnormal high temperatures noted during the summer and autumn. Furthermore, not only the rise in temperature but also the extreme drops in temperature during winter are among the abnormal weather patterns observed in recent years. Amidst the increase in such weather events, various problems have arisen in rooftop greening as well.

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 is there a rise in temperatures, 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: The Weed Problem 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 in seeds, or by being carried by the wind, leading to an overgrowth of weeds without notice. Special care is needed for greening projects on rooftops of factories where people do not frequently enter.

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 the drains. Initially, it is manageable, but over time, due to reasons such as becoming cumbersome or troublesome, it is often neglected and becomes 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 important to keep in mind that malfunctions can occur. This is particularly critical for corporate rooftop greening, where the irrigation system may fail during the summer holidays when no one is present, leading to complete destruction of the greening after the break. 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 Renovation (Waterproofing Renovation) When waterproofing renovation is necessary, it is required to remove the rooftop greening. This removal of rooftop greening becomes a very challenging task. The soil removal work requires a lot of effort, and there are also issues with 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 essential. It is also necessary to consider rooftop greening that makes waterproofing renovation 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, extreme weather events have increased, with "heavy rain" of over 80 mm per hour rising approximately 1.7 times in the last 30 years. Such intense rainfall can wash away the soil and plants in rooftop greening, causing issues like clogged drainage systems. Additionally, recent typhoons have become more powerful, necessitating consideration of scattering due to wind.

Soil Erosion Experiment One of the reasons for 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, abnormal 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 of rooftop greening, leading to problems such as clogged drainage systems.

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 the rise in abnormal weather patterns. In such severe weather, the soil and plants from rooftop greening can be dispersed, causing issues such as clogging drainage systems.

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.
