This paper presents a design procedure for external wall materials. It is significant and unique because it proposes a material design procedure which enables the selection of optimum materials in response to user's request based on a life-cycle assessment. The quality of material was evaluated qualitatively in three different terms, performance, economy and environmental conservation. Quantification was carried out as follows. For performance evaluation, the qualities of materials were graded and evaluation points were calculated by AHP (Analytic Hierarchy Process). Economy was evaluated based on the life-cycle cost. Evaluation in terms of environmental conservation was made according to the life-cycle carbon dioxide. The.material most satisfactorily meeting the design requirement in terms of a combination of three factors was selected as an optimum option.The suitability of the material was verified by model-based simulation for external walls to be used at a industrial plants of large scale steel structures.As a result, the validity of the proposed material design procedure was verified.
