This price winning concept is a smart vertical garden that minimises the effect of stormwater by collecting and storing all rainwater that falls on the rooftop of a building. The VRF is placed against a wall and connected to the roof drainage system.
The Vertical Rainforest (VRF) has a range of sensors that measure all kind of data 24/7such as temperature, moisture, air quality etc. The VRF is a high end IOT-solution. It takes in the most advanced weather data on the internet. This data is analyzed and interpreted by the VRF to take actions. How does it work? If heavy rainfall is predicted, the rainwater that is already stored inside the VRF will automatically run off to an infiltration point or to the sewerage. By the time rain starts pouring down, the waterstorage of the VRF is empty and ready to buffer all rainwater that falls down on the building rooftop. Until such weather conditions appear the VRF holds on to the stored rainwater. This rainwater can be used to water plants but it also has several other purposes, such as feeding a grey water system. Multiple VRF's together are capable to communicate with each other and build a smart watergrid.
NAME VERTICAL RAINFOREST
A rainforest is an exiting and inspiring ecosystem. It's a beautiful and self supporting circular environment. A number of important aspects of a rainforest can also be recognized in a VRF . First and most important is the plant system. In a 'normal' vertical garden plants grow in small baskets, containers or something in that area. These plants are artificially nurtured by a water- and food circulation system. In a VRF the plants are specially selected climbers. These plants root into natural soil, like plants in a forest. Therefore they can grow in a inarteficial way under natural conditions. Because of this the plants thrive to a richer system. At least eighty different climbing plants create a high diversity. But it goes even further. Like in a companion planting system (permaculture) or of course a forest, the plants help each other in growth and pest control. The plants together make the system healthier and more resilient. This is also one of the key features of a rainforest.
These are all prominent benefits that are in some way similar to the functions of a rainforest. But the real inspiration for the name Vertical Rainforest came forth from looking at the 'watermanagement' of a rainforest. Every drop of rainwater has a purpose and much of the water is stored in the layers of forest floor. This kind of storage and use of rainwater also takes place in the VRF. In a classic situation rainwater runs off via the water drainage system to the sewer. Now, with a VRF, the stored rainwater will moisture the plants in dry conditions . Plants only use a small percentage of the stored water. The vast majority of the stored water can either be infiltrated or used for all kinds of purposes. Furthermore, the VRF takes on the urban heat island effect, biodiversity will increase and many of the plants are edible. To sum it all up it's a tiny vertical rainforest in your city or town.
