The Reason Why We Should Cover All Our Buildings with Plants

Buildings covered in a cool carpet style of vegetation and greenery are emerging all over the globe – look at Bosco Verticale in Milan, One Central Park in Sydney , or Oasia Downtown  Hotel in Singapore.

I know you would wonder why in the world are planners and architects going green? A  Designing firm Arup just published a research on the advantages of plant-covered buildings – actually some of it are so green they look like they’ve been abandoned by humans and are slowly being colonized by nature and they discovered that the pros go way beyond just sucking up carbon IV oxide (CO2) from the atmosphere and looking attractive.

Engineers of the company took a multiply of measurements in five cities –which are: Los Angeles, London, Hong Kong, Melbourne, and Berlin – to see what effect extra greenery could have.
First and foremost, here is the most noticeable one: plants extract carbon dioxide out of the air and turns it into oxygen. With the number of green spaces in our overcrowded urban areas at a premium, moving vegetations and trees onto buildings is one way to make sure this vital process keeps going around us.


Green coverings can extensively reduce other pollutants in the air as well. Study has shown that even a plant on your table can enhance the quality of the air in your home.
While a few couple of skyscrapers might not fix city-wide pollution problem, the Arup’s’ research found that pollutants in the air amid two plant-covered structures could be decreased by as much as 20 percent margin.

Green buildings also perform an extra function which is cooling down our cities by restricting the ‘urban heat island effect’, where roads s and building emit heat on hot days.

Adele Peters of Fast Company reports, stated that Arup created a prototype of what compactly populated cities would probably be like with more green veneer, and discovered that in cities with a high-rise such as Hong Kong, green structures could help reduce temperature of about 10 degrees Celsius ( which is 18 degrees Fahrenheit).

And in the peak of summer, they discovered that a building roof covered in green vegetation could maintain an unchanged temperature as the ambient air temperature, where a non-green building roof can obtain up to a highly incredible 50 degrees Celsius hotter in the scorching sun (which is 90 degrees Fahrenheit).


With global warming, we could actually use some vegetation to counteract these effects.

With the shade given by these green vegetative coverings, indoor temperatures are often decreased too, and if the veneers are built in the right way, absorbing noise pollution is also possible.

A covering of shrubbery won’t block out the disturbance of traffic completely, but the research found out that, it did have positive impacts, specifically in the evening and on distant of more ambient sounds.

Another positive effect that’s not instantly obvious is an improved drainage – with plants and undergrowths there to soak up incoming rainwater and reduce the time it takes water to get from sky to soil, the destructive effects of flash floods aren’t as stern.

The research also states other advantages that are more complicated to measure: improved well-being for office workers who can enjoy cleaner air (and more nature), in addition a more different urban ecology, allowing insects and plants to grow.

The interestingly good news is that these green veneers can be built-in into existing structures or buildings. The team behind the report also stated that, solar panels and upright farming systems can easily be included.


Cities that are more ecological, quieter, safer, cleaner, more cool and more pleasant to work in – not bad for hardly any of layers of plant life.
“We now have the perfect opportunity to reorganize how cities can better improve green infrastructure and, simultaneously, help to decrease energy consumption, get better air quality and improve people’s wellbeing,” the Arup Cities Alive report said.
