The origin of the phrase "wow factor architecture" is uncertain, but has been used extensively in business management in both the UK and United States to promote avant-gardist buildings within urban regeneration since the late 1990s. It has even taken on a more scientific aspect, with money made available in the UK to study the significance of the factor. In research carried out in Sussex University, UK, in 2000, interested parties were asked to consider the "effect on the mind and the senses" of new developments. In an attempt to produce a "delight rating" for a given building, architects, clients and the intended users of the building were encouraged to ask: "What do passers‑by think of the building?", "Does it provide a focal point for the community?" The Design Quality Indicator has been produced by the UK Construction Industry Council, so that bodies commissioning new buildings will be encouraged to consider whether the planned building has "the wow factor" in addition to more traditional concerns of function and cost.
