Materials used to build the structure would include reinforced concrete (for the foundation), composite slab (wood/concrete), and timber wood. The floor will be made of a hybrid glulam (glued-laminated) beams and reinforced concrete. The building would include photovoltaic panels on the outer facade to generate electricity along with a "green wall" (aka "vertical garden"). The building will further protect the environment and public health through use of local resources, reduced routes of transport, use of sustainable materials, and significantly improved CO2 balance. Highly pre-fabricated construction will further reduce air pollution as well as construction site waste. In accordance with Passivhaus standards, construction of the LifeCylce Tower will reduce carbon emissions by 90% when compared to conventional construction.
The LifeCycle Tower will have plenty of other environment features, which you can read about at InventorSpot. Link
