Vanak Office Tower
An 18-storey tower with a double-skin façade and sky gardens, setting a new benchmark for low-energy office buildings in Tehran.
Vanak Square is one of Tehran’s busiest urban junctions. Set on one of its corners, the tower had to cope with noise and air pollution while offering flexible, daylit workspace.
A double skin
The south and west façades consist of two layers of glazing eighty centimetres apart. Automated aluminium blinds in the cavity control direct sun, and warm air is vented at the top of the skin. In the shoulder seasons staff can open the inner windows, something rare in Tehran office towers.
Every third floor has a double-height sky garden for breaks and informal meetings, which also helps keep indoor air fresh. A hybrid structure of concrete core and steel frame delivers column-free floor plates up to twelve metres deep.
- 38 per cent lower energy use than the reference building
- Bicycle parking and changing rooms for staff
