Functions of Plants
• 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.
(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
a. Privacy control
b. Screen objectional view
c. Progressive realization
d. Space articulation
(ii) Engineering Uses
• The engineering is primarily concerned
with glare, traffic, and sound control; airconditioning, or filtration; and soil erosion.
a. Glare reduction
b. Traffic control
c. Atmospheric purification
d. Acoustical control
(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.
The four major element of climate
human comfort are :
•
•
•
•
A) air temperature
B) solar radiation
C) air movement
D) humidity or precipitation
*Plant
control
solar
radiation
The sun’s rays are filtered through the
leaves of deciduous trees with relatively
light foliage.
*Wind
control
a. Air flow without vegetation
b. Air flow –
Low hedge
c. Air flow –
Medium hedge
d. Air flow –
High hedge
e. Air flow –
high and
medium shrubs
*Plant and rain
(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.
(a) Masking
(b) View direction
(c) Perspective control
(d) Perceptual control
