The building information model in performance-based design: characterisation and process

Abstract The concern with building performance has gained prominence in Brazil and generated significant changes in the Architecture, Engineering and Construction (AEC) sector. Recent research studies have proposed the integration of performance analysis into the early stages of the design process, aiming to achievethe best final building performance. Choosing an adequate set of solutions and computer aided ways to develop them is a highly complex task, involving great responsibility. This study investigates the understanding of the technique and utilization of performance computational evaluation tools in the early stages of the design process. Hence, an exploratory study was undertaken in order to clarify the relationships between performance requirements, computer aided evaluation and decision-making in the promotion of solutions aimed at improving the final quality of the project. Through a field study, it was possible elucidate the information model and identify the parameters that come into direct confrontation with each other as they are being shared by one or more performances. The influence between the performances can be also analysed, resulting in the proposition of a simulation sequence methodology.
