DPx - Design Performance Viewer


The Design Performance Viewer is a modular software framework that fuses design oriented building modeling with multi‐objective simulation, including advanced visualization and methods of statistical data analysis. It utilizes a rich building information model (BIM) and additional external databases for fast and intuitive input of parameters in an integrated design process.

Different calculation engines such as Energy+ (DOE), SIA 380.1 or Exergy (IEA Annex 49) have been integrated. The derived design support tool, the Design Performance Viewer (DPV) allows the fast and holistic analysis of building energy and mass flows, related building service systems and associated emissions, thereby allowing these issues to be considered already at an early stage in design. Unlike conventional simulation programs the DPV assesses multi‐disciplinary data to perform calculations directly from the Building Information Modeling environment. The software allows the modeling of a building as an integrated system, which in turn allows for a fluid work flow from early design sketches, through design development, and finally to detailing of construction and technical systems. Since 2007, the DPV has been applied internationally in both the professional and academic settings as well as in several case studies, such as the retrofitting of the HPZ building on the campus of ETH Hoenggerberg, the B35 case study, and as part of two joint industry ‐ university projects.


A sample application of the Design Performance Framework is the Design Performance Viewer (DPV), an add-in for Autodesk Revit Architecture 2014, that performs a dynamic simulation of design stage Building Information Models (BIM) with EnergyPlus and displays energy consumption and CO2 equivalents at the push of a button.
