The wood beam post slab configuration is also very earthquake resistant and holds up to fire without losing as much structural strength as steel. The Glulams beams are set in an interesting horizontal fashion to support the reinforced concrete slab. Utilities and lighting is then run in between the beams. Even the Passivehaus standard windows use wooden frames.
By pushing the limits of one of the most ubiquitous and potentially sustainable building materials and combining it with the benefits of prefab construction and the fantastic energy performance of Passivhaus design, the Lifecycle tower comes close to being the ultimate green building.
