Green Hall 2 in Vilnius – Energy efficiency for Lithuania
Centrally located between city centre and business quarter of Vilnius, a new office building is being built. Green Hall 2, located next to Neris River, will complement the already existing Green Hall building. The new hall is one of the most energy efficient buildings to be constructed in the last few years.
Green Hall 2 will accommodate offices on a total area of 10,000 m². It will use natural ventilation as well as solar energy. During construction, no compromises were tolerated that would have interfered with the innovative concept of the architects. The design and the extraordinary form of the building also required unusual structural solutions using cast-in-place concrete. This also included the suggestion of prestressing the building’s floor slabs using unbonded post-tensioning tendons.
Slabs were post-tensioned using approx. 1,300 monostrand tendons
Delta Nova, DSI’s Lithuanian partner company, coordinated closely with the project’s structural engineers and carried out the post-tensioning work for this project as a subcontractor. The slabs were post-tensioned using approx. 1,300 monostrand tendons with a total weight of 40 t.
