The purpose of this paper is to develop a quantitative appraisal model for assessing the inclusiveness of built facilities in higher education institutions. The Building Inclusiveness Assessment Score, or the BIAS, developed is used to assess the inclusiveness of the built facilities in the Hong Kong University. Design/methodology/approach ñ In this study, a comprehensive review of relevant guides and manuals in Canada, Hong Kong, Singapore, the US and the UK is conducted. Two Multiple-criteria Decision Analysis (MCDA) techniques, the Analytic Hierarchy Process (AHP) and the Non-structural Fuzzy Decision Support System (NSFDSS), are studied and compared and the latter is applied to analyse the weightings of inclusion attributes. On-site appraisals of 28 buildings in the Main Campus of the Hong Kong University are carried out and shortcomings resulting in exclusion are identified. Findings ñ Using the BIAS, the common areas of the built facilities in the Hong Kong University are appraised. As suggested by the preliminary result, the built facilities are not fully inclusive and there are ample rooms to improve their inclusiveness. Areas that require immediate attention are those related to the access and the safety of persons with disabilities (PWDs). Originality/value ñ Access audit and access appraisal are the methods adopted to appraise the inclusiveness of built facilities nowadays. This research seeks to obviate their shortcomings by minimising the subjective judgements of the assessors in the BIAS proposed. Compare with earlier studies in the subject, more quantitative elements are incorporated into the BIAS and its assessment procedures are detailed.
