CTBUH 10 Year Award

The ten year award is given for how a building has performed since it opened, which is what separates it from the awards decided at completion.

A building becomes eligible ten years after it is finished, so the award and the completion date are always a decade apart.

The Council on Tall Buildings and Urban Habitat is the body that also decides how tall buildings are measured, so its awards and its height rankings come from the same organization.
