Why does rooftop greening fail? [Structural Causes]
A technical explanation site that does not conduct product comparisons or method evaluations: The failure of rooftop greening is determined not after construction, but before the decision is made.
Is that rooftop greening really being considered on the premise of "being established"?
This site is not intended to introduce or recommend products, methods, or construction techniques for rooftop greening. In rooftop greening projects, failures such as "installed but deteriorated within a few years," "not dead but not turning green," and "management was not sustained, resulting in neglect" are repeatedly occurring. Many of these issues arise not from construction or management problems, but from discrepancies in the assumptions and thinking established in the early stages of consideration. This site provides a structured overview of "why it is easy to make erroneous judgments" and "where the assumptions are being misrepresented," offering perspectives to pause during the consideration phase.

Company information
In manufacturing, there are people, and in projects, there is drama. The "passion" of three individuals transcends the boundaries of the company to create "co-creation" and "hope." In April 2007, at an exhibition, a certain project team was born. They wanted to create new solutions originating from the field to solve customer problems. Three professionals who shared such a passionate desire met, leading to the establishment of the Evergreen Kiri-Sou Promotion Association. Professionals in plants, architecture, civil engineering, and equipment breathe new life into the city. A series of moving moments. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because the number of fakes and forgeries has increased. We aim to continue being professionals involved in plants, architecture, civil engineering, and equipment, 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.
