11.8 Efficiency of Trees for Reducing CO 2 /1000 cm 2
The following is an explanation of some of the common species cultivated in Egypt
[142, 143] and has a role in the disposal of carbon dioxide that causes climate change
which are also important in tempering the atmosphere, which also affects climate
change.
12 Vertical Gardens to Reduce Climate Change
12.1 Benefits of Using the Vertical Garden System
1. The benefits of the use of the walls vary according to several criteria. Perhaps
the most important of which is the location of the origin and the method and
manner of cultivation of the outer envelope and the nature of the surrounding
environment. In addition to the aesthetic character and the establishment of a
distinct environment and an enjoyable environment of existing architecture, these
benefits can be arranged under three main titles [144]. On the environment scale
2. On the scale of the building
3. Scope of users
On the environmental scope, Results of Safikhani et al. [145] showed that the living
wall and green facade reduced indoor temperature up to 4.0 and 3.0 °C, respectively.
The living wall and green facade also reduced cavity temperatures by 8.0 °C and
6.5 °C, respectively.
The beauty of this system is that more than 90% of the water goes directly to the plant and
the absorption rate is lower as compared to normal absorption of water by the plants (http://
www.talkafrica.co.ke/vertical-gardens-technology-to-reduce-climate-change).
Vertical gardens, especially, which use solar energy have come as a savior to those
living in high polluted areas, water stressed and less space environments. The beauty
of this arrangement is that more than 90% of the water drives directly to the plant
and the absorption amount is lesser as compared to regular absorption of water by
the plants [146].
One of the major problems in landscape design in crowded cities, like Cairo, Giza,
Tanta, Assiut etc. in Egypt, is looking to find free areas to establish new gardens,
also old methods of street trees maintenance still used. We recommend following the
new systems of external surfaces cultivated at least for the governmental buildings,
using different plant species with higher efficiency in absorbing carbon dioxide (and
other common pollutants in every city). Research of Koriesh [17, 139] indicated
that the use of Sciendapsis aureus, Dracaena with narrow leaves (D. marginata),
Chlorophytum comosum and Aspidistra elatior plants for cultivating façades and
Vertical gardens showed the highest efficiency in the elimination of carbon dioxide.
