Architectural Design Quality Assessment Based On Analytic Hierarchy Process: A Case Study

ARCHITECTURAL DESIGN QUALITY ASSESSMENT BASED ON ANALYTIC HIERARCHY PROCESS: A CASE STUDY OZET VE ANAHTAR SOZCUKLER Abstract Architectural design quality is hard to evaluate due to its complexity. Defining criteria, setting forth a methodology and deciding on who is going to assess the quality for whom are also on-going discussions to date. To this end, tools have been developed, yet they are mostly used for post-occupancy evaluation, thereby not contributing to the design stages in progress. This article aims to reveal a new, Analytic Hierarchy Process (AHP) based approach for the assessment of architectural design quality which can be used for design stages starting from pre-design to final design. Multi Criteria Decision Making (MCDM) is a powerful and comprehensible system that allows groups or individuals to combine qualitative as well as quantitative factors in decision-making processes. AHP, a MCDM method, structures a decision problem into levels forming a hierarchy. As quality is in the eye of the beholder, an AHP-based approach aims to improve architectural design quality in the design process through the contribution of stakeholders’ preferences through the design processes. The proposed approach is implemented in a case study in cooperation with one of the biggest private health care providers of Turkey.
