USER-FIT: A framework to evaluate the usability of building performance simulation tools in the architectural design process

There is no consensus on usability testing in studies investigating the integration and decision support of building performance simulation in the architectural design process. This report presents an evaluation and reporting framework for usability testing and user experience investigations of building performance simulation tools in workplace and laboratory settings. A six-step usability testing framework USER-Fit is presented based on the Delphi process involving international experts and a review of standards. A framework lists the steps to perform document and report user experience evaluations during the design workflow and design process. The implementation of the framework will enhance the impact of simulation-based design decision support by ensuring a structured and systematic approach and enabling objective and comparative evaluation of building simulation tools. The framework is the first formal study for documenting and reporting usability studies interventions in the architectural and building design process.
