As part of a fourth semester architectural design studio, students perform an analysis of selected precedents according to various criteria. For this purpose, they are provided with a web-based environment for the storage and management of their analyses. In this way,, and By integrating the analysis results into a common, extensible, library, the students are able to benefit from a collaboration with peers, and draw upon each othersi results for comparisons and relationships between different design aspects or buildings. In order to support this integration and strengthen the collaboration, we are developing organization and presentation tools that are integrated within the webbased environment. In this paper, we describe the context as provided by the design studio course, reflect on the advantages of a web-based repository for managing design and analysis information, describe the techniques we are developing to improve this process, and present the implementation of the resulting tools within the web-based environment.
