This paper focuses on the essential criteria, which expert users could consider during their decision-making process involving an interior paint, as well as awareness of LCA (Life Cycle Assessment). Therefore, a qualitative study with a questionnaire survey was conducted on the construction market in Germany. This study involves the main characteristics of the decorative paints and coatings, available on the European construction market. Objectives of the study are finding out which criteria of a decision-making process score the highest for the expert users in Germany. If the result overall score reflects the assumed hypothesis that environmental and health issues as well as sustainability are the most important for the decision-makers. Also, how can awareness of LCA or addition of a full declaration influence their decision-making process. The results of the study serve as a base for the multi-criteria decision-making model using AHP (Analytic Hierarchy Process) presented in the paper.
