1. GREEN WALLS

2. GREEN WALLS
Green walls (also known as plant walls, living walls or vertical
gardens) have become a rising new trend of built environments in
recent years. Incorporating living nature into urban environments
not only looks much more inviting, but also has a number of other
benefits and purposes.

3. Basic types of green walls
• Wall climbing -green walls
is the very common and
traditional green wall
method . Although it is a
time consuming process,
climbing plants can cover
the walls of building
naturally can cover the
walls of building naturally,
somtime they can grown
upwards with the help of a
trellis or other supporting
system

4. Hanging down
• Green wall is also another popular
approach from green walls. It can
easily from a complete vertical
green belt on a multi-story building
through planting at every story
compare to the wall climbing type

6. Module
• Module – green wall is
the latest concept
compared to the previous
two types. It requires
more complicated design
and planning
considerations before a
vertical system can come
to place. It is also
probably the most
expensive green walls
method.

8. Advantages
• Lower energy bills
Vertical gardens aren’t just cool to look at; they’re quite literally
“cool”. Living walls provide a natural layer of building insulation,
cooling interior temperatures and breaking down airflow.
• Anti-pollution power
it’s a simple fact: nature is good for our health. Fresh air and a
calm environment does wonders for our well being; even just
seeing nature has been shown to reduce stress and boost
energy.
• An eye-catching aesthetic
There’s no denying plant walls and vertical gardens have an
aesthetic appeal. These living, breathing adornments enhance a
building’s visual appeal and buyability.

12. Disadvantages
• Possible structural damage
One of the potential downsides to green walls is a long-term impact on
a building’s structural integrity, especially when plant roots start to
reach beyond their confines and into walls or plumbing.
• Maintenance Obligations
Green walls and roofs require a great deal of maintenance. Because of
the dangers to the structure, thorough and professional maintenance is
a must. Plants require a constant water supply, so piping or rainwater
harvesting need to be installed and maintained
• Ongoing Costs
Living green walls can be expensive to install, and even more
expensive to maintain
