BIM in early design phase: Workflow for preliminary assessment with SBToolCZ

Abstract

Early design phase provides the highest potential for saving emissions and energy. Building Information Modeling (BIM) in cooperation with environmental assessment can be efficient tools for various kinds of analysis. This paper shows a possible workflow of using data from BIM in an online form for an early building assessment. Different methods of data export are also described. Czech national methodology, SBToolCZ was used for this study. However, the described principles are applicable for any other commonly used method. Results show approximately 60% of precision compared to the full SBToolCZ assessment (depends on the building typology). As an outcome of the study, a free online tool for architects and public usage is being developed.
