Abstract: The aim of this paper is to present the visualization process of an approach for analysing robust passive measures through the time-based metrics of thermal autonomy and passive survivability. The objective is to provide a common language and fill the communication gap between architects and engineers through a practical visualization technique, so that architects may maintain better control over their aesthetic and functional design values without compromising performance. For this study, parametric simulations of multi-unit residential buildings are conducted in a given climatic location. The results are discussed using these two metrics through graphical feedback to ensure architectural parameters, such as building form, orientation and fabric, are intelligently selected to improve environmental performance and resilience of buildings. Further, an online survey of design professionals was developed and conducted in order to evaluate the utility and effectiveness of visualizing these time-based metrics to inform the design development process. The paper discusses the results of the survey and attempts to fulfil the comments of participants. The majority of survey participants responded that both thermal autonomy and passive survivability are useful metrics to visualize, with somewhat more preferring passive survivability.
