More people have become environmentally aware, and work in various ways to be greener. One such way people have become greener is to create and cultivate roof gardens. And, once limited to buildings and other similar structures, roof gardens can now be found on moving vehicles.

That’s right! Moving vehicles like buses and vans. That means the next time you are waiting for the bus, you could get an environmentally friendly ride to your destination. Roof gardens on bus tops are showing up in various parts of the world.

How Are Rooftop Gardens Created On Vehicles

Now, you might be wondering, how in the world can gardens be grown on rooftops of vehicles? That’s a good question. And, it’s not as hard as one might think. These phytokinetic gardens created out of aquaponics foam are rooted in a steel grid that ensures the plants stay in place even in cases of sudden stops. A sedum carpet of succulents keeps the flower bed moist along with ferns and small shrubs. The entire area is covered using a protective mesh.

The vehicle’s air conditioning system waste waters the plants. And, with rooftop gardens, the buses see an automatic cool-down of 3.5 degrees Celsius, which saves on the vehicle’s air conditioning.

A roof garden also helps to reduce how much weight is on the roof of the bus. And, since soil isn’t used, additional weight isn’t a concern.

What Benefits Are Associated With Rooftop Gardens?

There are several worthwhile benefits to the rooftop gardens of moving vehicles including but not limited to:

  • It increases the aesthetic value of the bus.
  • It provides both Thennal and Acoustical Insulation
  • It increases the absorption of CO2 emissions.
  • It reclaims real estate that has long been forgotten.
  • It boosts public awareness and recreation.

What’s so popular about moving roof gardens? Well, the idea behind them is to lessen the amount of carbon dioxide being released into the atmosphere while also boosting the amount of overall vegetation and bio-diversity in crowded cities, especially in cities that are limited in space due to infrastructure such as Tokyo, Barcelona, etc.

One Creator of Rooftop Gardens

There hasn’t been just one creator of the rooftop gardens, and the design’s birth was for various reasons. One such creator is New York City designer Marco Cosio, who used the idea from his graduate thesis. He designed rooftop gardens to make use of forgotten space on the city buses while also bettering urban life with greenery.

A prototype of his design was installed on the BioBus’ roof. The BioBus is a mobile science laboratory and has become the first bus to have the detailed green roof system. It’s been seen in areas around New York City and has even traveled to Ohio and other places in the Northeast United States. Of course, the BioBus is just one several other mobile gardens, which have been found on trains, trucks and other various other moving items.

Cosi said the public transit buses have a surface space of 340 feet with the Metropolitan Transit Authority owning about 4,500 buses. The amount of green space in the city could expand exponentially. Basically, that means an additional 35 acres of green space.

With so many benefits behind this concept, and the ease in which to implement it, it can definitely be viewed as being the wave of the future. And, there is little doubt that moving roof gardens – be it in the form of buses, trucks, cars, or trains - could be the best in carbon-neutral motoring. You can create one yourself, if you think a home roof garden of plants is doable, than you should go and take part in saving the planet.
