Setting the key issues and a prioritization strategy for designing sustainable interior environments

Designers should operate an effective strategy to increase the possibility of creating sustainable built environments. This paper aims to evolve a framework that is composed of the sustainable interior environment issues acting as the basis that contribute positively to humans' well being through the efficient use of site, energy, water and materials and resources in the built environment. The C-K theory, which defines the design process as an interaction between the space of concepts (C) and the space of knowledge (K), is suggested as an innovative approach to design practice. Using morphological analysis with the cross-consistency assessment technique, all compatible relationships, with their assigned values, are determined. Further, the study prioritizes the components of a sustainable interior environment into most important, moderately important or least important and ranks them from highest to lowest. This study proposes an innovative approach to interior design practice that incorporates sustainable characteristics to the built environments.
