The towers will contribute to improve the air quality by using the height of the buildings to host purifying towers extracting the air on ground level and filtering the air. The air chimneys will be built as lightweight transparent ETFE tubes, attached to the vertical circulation core, and connected to an ETFE solar roof at the base of the towers.
The facades of the towers will be provided with generous terraces and generous outdoor spaces to all residential units. These terraces will shade the facades to reduce solar loads and dissipate heat.
Every tower will have a rooftop greenhouse working in conjunction with the ventilation chimney, as a further step to oxygenate the environment. Furthermore, the rooftop greenhouses will allow for residents to grow vegetables, and exercise, or as a playground for children.
