What is the 'Urban Heat Island' effect?


This is the phenomenon that the average temperature in the city is always higher than in the countryside. This difference is usually 4°C and the difference is the highest at night. The higher temperature has a few causes: - In the city are more dark materials that heat u really fast in the sun. - There is less wind in the city, so less cooling. - A lot of heat is released from cars, air conditioning an so on. - Concrete stores a lot of heat during the day and relaese it during the night.




What's the weight of a greenwall


The weight depends on the system you use. There are systems that weigh 40kg/m², but also of 150kg/m². The systems we use are around 50-80kg/m², if it's saturated with water.




Wich plants are used in greenwalls


The plant assortment used must be tailored to the conditions in the façade. We can not just put every plant in the greenwall and the orientation of the wall also plays a role. We are currently testing various plant species in our own green wall. The plants that stare at are evergreen perennials or shrubs, preferably with flowers and variety in leaf colors. Species like Heuchera (photo above) and Euonymus are already doing very well.




How do the plants get water


The plants get water from an irrigation system that runs in the rockwool between the roots of the plants. Through these hoses runs the water and fertilizers for the plants. Like this we make sure of a nice spread of the water inside the system.




What is the maintenance of a greenwall


The maintenance is the same as a normal garden. The greenwall is pruned twice a year to keep it compact. With this pruning also the irrigation system is checked. Furthermore, care most be taken that the pump installations stays in good condition and doesn't fall without electricity.




How much water is used.


Water consumption is reduced to a minimum by means of humidity sensors. Measuring every 10 minutes the humidity in the wall and if it is too low the irrigation gets started. The amount of water that is needed depends on the choice of plants, the season and the orientation of the greenwall.
