In response to continuing Building Information Modeling (BIM) progress, building performance simulation tools such as IESVE are being utilized to explore construction projects and influence design decisions with increasing frequency. To maximize the potential of these tools, a specification of information exchange and digital workflows is required. This paper presents the preliminary findings of an ongoing study aimed at developing an Information Delivery Manual (IDM) for IT supported energy analysis at concept design phase. The IDM development is based on: (1) a review of current approaches (2) a qualitative survey of professionals within the industry, and (3) mapping of selected energy simulation tools. Specifically, this study focuses on the issue of implementing standardized IDMs across national borders (in this study Denmark and Sweden).
