Universal Design (UD) offers different sets of principles that can be used as reference in design practice to meet the needs of the vast majority of a population.

A hierarchical framework was created, consisting of three main categories of UD (i.e. physical-spatial quality, sensorial-cognitive quality, and social quality), eight criteria (i.e. usability, functionality, safety/security, wayfinding, understanding, environmental factors, well-being, and social inclusion), and 21 indicators. The proposed framework can be considered as an innovative approach in the field of accessible design evaluation since it explores the relation among a multiplicity of aspects, including human performance and social factors, to evaluate the quality of UD buildings.

Abstract

Universal Design (UD) offers different sets of principles that can be used as reference in design practice to meet the needs of the vast majority of a population. However, there is a lack of an accountable approach to measure and analyze the built environment through UD performance. This study aims to develop an evaluation framework to assess UD in public buildings to determine, in addition to accessibility requirements, the usability and inclusion of projects for different users. Multicriteria Decision Analysis (MCDA) was adopted as research methodology to systematically and scientifically develop the framework, which was structured based on knowledge derived from: an in-depth literature review on UD evaluation and workshops with stakeholders and experts. The selection and comparison of a pool of criteria is described including the cognitive mapping technique for translating information gathered by workshops. A hierarchical framework was created, consisting of three main categories of UD (i.e. physical-spatial quality, sensorial-cognitive quality, and social quality), eight criteria (i.e. usability, functionality, safety/security, wayfinding, understanding, environmental factors, well-being, and social inclusion), and 21 indicators. The proposed framework can be considered as an innovative approach in the field of accessible design evaluation since it explores the relation among a multiplicity of aspects, including human performance and social factors, to evaluate the quality of UD buildings.
