Table 3 Description of ranges for the synthetic indicators used to assess water and light.
Category (Light) | Range and description* |
|---|---|
Very low | Indoor conditions without direct solar radiation |
Low | Forest canopy 100–75% |
Med. Low | Forest canopy 75–50% |
Med. | Forest canopy 50–25% |
Med. High | Forest canopy 25–5% or cleared areas in N exposure |
High | Cleared areas in W-E exposures |
Very high | Cleared areas in S exposure |
Category (Water) | |
Very Low | Vertical surfaces protected by incident rainfall in any exposure and in any condition of forest canopy cover |
Low | Vertical and horizontal surfaces partially protected by incident rainfall in cleared areas in all exposures, and vertical surfaces with forest canopy cover between 50–75% |
Med. Low | Vertical and horizontal surfaces exposed to incident rainfall, without percolation events - with forest canopy cover of 75–50% in S exposure; or with forest canopy cover of 50–25% in W-E exposures; or with forest canopy cover lower than 25% in N exposure |
Med. | Vertical and horizontal surfaces exposed to incident rainfall, without percolation event - with forest canopy cover of 50–25% in S exposure; or with forest canopy cover lower than 25% in W-E exposures |
Med. High | Vertical surfaces interested by percolation or rising damp (lower parts) with forest canopy cover lower than 25% in any exposure. Horizontal surfaces with forest canopy cover higher than 25% |
High | Horizontal surfaces receiving incident rainfall, in semi shadow conditions with a forest canopy cover of 50–25%. Vertical surfaces interested by percolation or rising damp (lower parts) in any exposure |
Very High | Horizontal surfaces receiving incident rainfall and interested by raising damp (lower parts), in shadow conditions under a forest canopy higher than 50%. Vertical surfaces interested by percolation or rising damp (lower parts) in any exposure |
