I was looking for easy ways to go green. I was looking for something different and something that is not going to change my daily routines and I came across an interesting concept called green walls or living walls. These are self-sufficient gardens that can be attached to the inside or outside of a building or home.
These vertical gardens differ from other plant-covered walls in which the plant roots in a structural support right to the wall filled with nutrients, rather than the ground. Many hospitals, hotels, spas and business buildings located in major cities are beginning to include these walls to their interior and exterior design.
These walls provide great benefits economically and environmentally, and they are beautiful. They are unique and can be planted in many different shapes and sizes using a variety of plants and flowers. Some benefits include: saving energy, improve indoor air quality, and sustainability.
Studies have shown that the surface of an exterior green wall is up to 10°C cooler than an exposed wall, therefore less heat is radiated inward. Meaning in the summer, saving money on air-conditioning. Not only do green walls reduce cooling requirements but they also help to mitigate the urban heat island effect.
During winter, the living wall acts as extra insulation. There is an additional layer of air between it and the wall, which reduces the amount of heat escaping, and cool air coming in.
Indoor Air Quality:
The average person spends over 90% of their time indoors. We are constantly being bombarded with indoor air pollution. A single potted plant removes a portion of these airborne toxins and with each additional plant this increases. A green wall can contain over a thousand plants, all of which filter air and in addition create energy-rich oxygen.
Here is a link to common indoor toxins, and best plants that can remove them.
Green walls help buildings and homes become more energy-efficient, which leads to a decrease in carbon emissions. They also mitigate the urban heat island effect, absorb and filter storm water, reduce pollution and act as carbon sinks.
Another interesting thing about these walls is that you can grow basic vegetables in them. Lettuce, carrots and herbs were found to successfully grow in these walls. Looking at how extravagant these walls look and how much more popular they are becoming; installation may cost a pretty penny so I found ways to DIY. These are just basic ideas that have the same effect.
I think these walls are a cool easy way to help rebuild and clean our environment. With the only major restriction being allergies to flowers or plants, these walls would be something simple and inexpensive that anyone could and should do.
