This paper describes the translation of an academic methodology for teaching building performance issues into the realm of professional practice. To paint this case study, the paper presents a brief history of the evolution of the Vital Signs Project through the Agents of Change Project and into Tool Days, describes efforts to adapt Vital Signs methods and philosophy to professional practice, and compares participant evaluation results from several Agents of Change and Tool Day workshops. Findings to date indicate that the Vital Signs approach to building evaluation provides successful, engaging training for audiences from a range of disciplines and settings. The success of the technology transfer is validated by the incorporation of Vital Signs methods into the everyday work of the practice in question.
