Solution

In urban areas it is becoming less and less space for greenery. We can change this by making the buildings green.

The roofs of greenhouses are used to collect rainwater, which is then used to irrigate green spaces inside the greenhouse. Warm air from natural ventilation can be used as a heating for greenhouses. Internally green area of greenhouses can be used for recreation, sports or even as an office workspace. Besides the low cost of maintenance of this space can be used for business by breeding different greenhouse crops. For example flowers cultures, or fresh herbs. Greenhouses may be open to the front, or can be hidden and not affect the design of the facade.
