Vegetative walls

·         Vertical greenery systems can be broadly classified into 2 major categories:

1.      green façade

2.      living wall.

The 2 frequent green façade systems are the modular trellis panel as well as the cable and wire-rope net systems while the use of planter-cassettes or the modular system with substrate are commonly found in living wall systems

                                                  

THERMAL IMPACTS

·         have the best cooling efficiency throughout an entire day for the average temperature reduction of the wall surface

·         best capacity for substrate surface temperature reduction

·         potential thermal benefits of vertical greenery systems

·         reduce the surface temperature of buildings facades in the tropical climate

·         lead to a corresponding reduction in the energy cooling load and consequent saving in energy cost

ADOPTABILITY AND PLANT SUITABILITY

·         Plants species must be able to tolerate the high temperature and periodic temperature fluctuation of Singapore’s weather.

·         Substrate moisture requirements of plants, their tolerance to drought and periods of water stress as well as their ability to tolerate moisture on their surface must be taken into account.

·         Climbing habit and their degree of aggressiveness of growth should be reviewed to ensure its aesthetic performance.
