“…This initial design is then 34 iteratively refined in subsequent design stages based on an analysis of its performance using 'downstream' applications. The 35 downstream applications can also be used for purposes such as to check compliance with building regulations [10], or to support a 36 certification process. An example of the latter is the Excel-based low energy design tool Passive House Planning Package (PHPP).…”

8The process of building design is currently undergoing some major changes. In an attempt to mitigate climate change, the design 9 of more sustainable building is advocated by the UK government. Furthermore, standalone design methods are being replaced 10 with the concept of Building Information Modelling (BIM). The adoption of BIM has been documented to result in many benefits, 11 which range from time to cost savings. During the initial planning stages, building performance simulation (BPS) can be used to 12 inform design decisions. Data can be exchanged between BIM and BPS tools using data transfer schemas such as the Industry 13Foundation Classes (IFC). The IFC schema lacks an energy domain, and as a result, an extension is proposed in this paper. This 14 contains energy concepts from a BPS tool called Passive House Planning Package (PHPP). The extended schema was developed 15 by way of an externally coupled Java tool, which facilitates the transfer of data, and informs the building design decision-making 16 process. The process of geometry extraction has been validated with several case studies, which are based on certified Passivhaus 17 buildings in Hannover Kronsberg, Germany and Ebbw Vale, Wales. The amount of error is acceptable, and it is mostly due to 18 differences in the initial BIM model set up, not due to the processing of IFC files. 19
