2. Functions of Plants

3. The functions of plants should be the basis for their use in environment design. The primary aim of planting design should be to use plant in solving environment problems Basic to this is a knowledge of their characteristics, what functional problem they solve, and how effectively they solve them.

4. (i) Architectural Uses Plants, singly or in group, form walls, canopies, or floor of varying heights and densities; these are architectural characteristics In designing building, the architect uses materials to give privacy, to screen, to progressively reveal a view, or to articulate space

5. a. Privacy control

6. b. Screen objectional view

7. c. Progressive realization

8. d. Space articulation

9. (ii) Engineering Uses The engineering is primarily concerned with glare, traffic, and sound control; air- conditioning, or filtration; and soil erosion.

10. a. Glare reduction

11. b. Traffic control

12. c. Atmospheric purification

13. d. Acoustical control

14. (iii) Climate control Shade trees and windbreak trees are examples of plants used for climate control. It is well known that plants alter adverse microclimates, making the environment more pleasant and livable for man.

15. The four major element of climate human comfort are : A) air temperature B) solar radiation C) air movement D) humidity or precipitation

16. *Plant control solar radiation

17. The sun ’ s rays are filtered through the leaves of deciduous trees with relatively light foliage.

18. *Wind control

19. a. Air flow without vegetation

20. b. Air flow – Low hedge

21. c. Air flow – Medium hedge

22. d. Air flow – High hedge

23. e. Air flow – high and medium shrubs

24. *Plant and rain

25. (iiii) Esthetic uses Visual Controllers Plants are visually controlling elements positive element The plant is a positive element when it is an object to be seen and to be noticed, and when the plant or its parts are what is important or of interest. negative component When the view beyond is what is important, the plant directs or blocks. It exists to enframe a view.

26. (b) View direction(a) Masking

27. (c) Perspective control (d) Perceptual control
