Dataset for multi-criteria decision analysis (MCDA) and life cycle assessment (LCA) of solar collector materials

This dataset contains the supplementary materials and detailed calculation tables for the research article, "Systematic design and optimised material selection for sustainable and efficient solar water heater flat-plate collectors". The data supports a systematic material selection framework that integrates Ashby's method, multi-criteria decision analysis (MCDA), and life cycle assessment (LCA) to evaluate 4,249 materials based on thermal, mechanical, and economic criteria. This dataset specifically documents the final stage of this framework: the comprehensive MCDA process used to rank the 57 shortlisted candidate materials for the solar collector material.
