GreenHab officer: Masashi Hiraki
I had counted up the holes that GreenHab are having. The number of holes are 65, and I classified holes into 2 categories by the reason of getting holes.
Firstly, the holes were caused by bolting on cover. Secondly, they were caused by other reasons, for example, windy, stones and other accidental reasons. First reason’s holes are 57, second reason’s holes are 8. I am attaching 4 photos of some holes for each reasons. Actually, I wouldn’t count correctly because it is having many many holes.
