Table 3 The classification of each factor grade in orthogonal experiment considering the effects of the interaction between the elements on thermal comfort, the test program for the functional space was selected using the table below. The test was calculated only for the nine working conditions in the table due to the consideration of the interaction between the elements, as shown in Table 4.
Factor level | Tree coverage (A) | LAD (B) | Green patterns (C) |
|---|---|---|---|
1 | 30% | 0.8–1.0 | Tree |
2 | 50% | 1.0–1.2 | Tree + grass |
3 | 70% | 1.2–1.4 | Tree + shrub + grass |
