Abstract

Although sustainability has long been a top priority in the built world, sustainable interior architecture and design still has room for improvement. This study set out to find and examine the obstacles that prevent sustainable interior architecture and design from being practised. In order to do this, 30 potential barriers were identified through a review of the literature; then, using a two-round Enhanced Fuzzy Delphi Method with 13 certified experts, 10 of the potential barriers were excluded, and one new one was added. A novel Parsimonious Cybernetic Fuzzy Analytic Hierarchy Process was devised to prioritise the remaining data, greatly lowering the amount of pairwise comparisons and doing away with the requirement for a challenging AHP questionnaire.
