The Twenty-five Year Award is an architecture prize awarded annually by the American Institute of Architects (AIA) at its general meeting, which is geared towards the durability of the building and its concept.
Selection criteria
The award is given to buildings that were completed more than 25 years - a maximum of 35 years ago - and whose design has proven to be good, i.e. a good example of enduring architecture. The country in which the building is located does not matter, although all but two buildings are in the United States. Another requirement is that the designing architect was licensed in the United States upon completion, which means that foreign architects can also receive the award. The building must have been completely preserved in accordance with the design and be in good condition. Changes in function are partially permitted.
Each AEI member can propose a building that meets the criteria. Repeated proposals for the same building are also permitted as long as the requirements are met. The jury evaluates the proposals taking into account current standards with regard to their function, execution and creativity. The assessment concerns both the building and its location.
"The project must have excellence in function — in the distinguished execution of its original program and in the creative aspects of its statement by today's standards."
With the exception of one award winner in Spain and one in Saudi Arabia, all buildings are in the United States. New York, Illinois, Connecticut, California, New England, and Washington DC each have more than one building with the award.
