#3 From Hanging Gardens to Green Walls
For some, the Hanging Gardens of Babylon remains as a mythological place built as a gift for the wife of Babylonian king in the sixth century B.C. Its aim was to reduce the extreme hot and arid weather in ancient Babylon. The exuberant vegetation hanging with perfumes refreshed the air and gave it a luxurious and elegant view. Surprisingly, nowadays the “booming” of greening indoor and outdoor spaces is back. The notion of being close to nature and adopting environmental friendly alternatives to cool, heat and ventilate places is used again. Now green walls and roofs are grabbing scientist, architects, and environmentalist attention, not just because their “fancy decorative functionality”; also it is scientifically proved their benefits of trapping air pollutant (NO2 or PM10 ) through Photosynthesis.
Another creative, interesting, and sustainable alternative to be installed into a green wall is a microsystem inside of it.
How…? Through Aquaponics. What’s it?
It is a system combined by the growth of fish and plants where both are feeded by the fish waste. This alternative works if we want to plant our own vegetable of fruits. For example you can plant lettuce, tomatoes, arugula, basil, mint, common house plants, peppers, cucumbers, beans, peas, broccoli, cauliflower, cabbage.
Finally, the visual impact that people are exposed everyday also counts. Studies suggest that people who remain long time indoors are affected by their surroundings being more or less productive. For example: hospital patients, office workers, children, etc. Patients can take longer time to be cured; office workers can get easily distracted (green walls can be used as barriers between each set of desks or people need nature close to them to be more efficient), and as close as a child can be from nature, as much he can learn from it, enjoy it and have a healthy childhood.
