The Design Quality Indicator (DQI) is a toolkit to measure, evaluate and improve the design quality of buildings. Development of DQI was started by the Construction Industry Council in 1999〔Page 6, Spencer, N. and Winch, G. (2002). ''How Buildings add value for clients'', London: Thomas Telford. ISBN 0-7277-3128-9〕 and the toolkit was launched as an online resource for the UK construction industry on 1 October 2003.〔Construction Industry Council. ''(DQI Online – How well is your building designed? )'' 1 October 2003〕 In 2004 the DQI received recognition from the British Institute of Facilities Management for the role of involving users in the design process.〔The Structural Engineer ''(DQI online service gets recognition from BIFM – The Structural Engineer )'' 2 November 2004〕 The DQI tool was made available to users in the United States in 2006, and an online American version was launched on 20 October 2008. ==Conceptual framework== DQI applies a structured approach to assess design quality based on the model by the architect Vitruvius, the Roman author of the earliest surviving theoretical treatise on building in Western culture, who described design in terms of ''utilitas, firmitas ''and ''venustas'', often translated as commodity, firmness and delight.〔Gann et al. (2003), ''Design Quality Indicator as a tool for thinking: Building Research and Information'', London: Spon Press. 〕 DQI uses a modern day interpretation of these terms as: *Functionality (''utilitas'') – the arrangement, quality and interrelationship of spaces and how the building is designed to be useful to all. *Build Quality (''firmitas'') – the engineering performance of the building, which includes structural stability and the integration, safety and robustness of the systems, finishes and fittings. *Impact (''venustas'') – the building’s ability to create a sense of place and have a positive effect on the local community and environment. 452 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Design quality indicator」の詳細全文を読む スポンサード リンク
