Ecodesign tools in the construction sector: analyzing usage inadequacies with designers' needs Supplementary files are provided at the end of the document, after the references. Highlights Current ecodesign tools fail to meet building designers' needs. Interviews lead to a model of usages, problems, and solutions in building ecodesign. The DSM Value Bucket algorithm analyzes the matching between tools and practice. Tools are missing in early stages, for multicriteria analysis and benchmarking. Conclusions are also drawn on the integration of the building design process.
