designPH 2.0 – new features

  • New shading analysis based on 3D ray-tracing and Perez radiation model. Complex shading scenes can be analysed accurately and both winter and summer shading factors can be exported to PHPP.
  • New “Compare results” tab allows the key analysis results to be tracked and compared over time as the model evolves.
  • Assignment of user-defined Thermal Bridge component entries.
  • Additional ventilation inputs such as the ventilation strategy, MVHR unit selection, pressure test result and more.
  • Improved automatic naming and ordering of windows and surfaces.
  • Improved User Interface.

The main highlight of this version is the new shading analysis based on 3D ray-tracing and Perez radiation model.

Currently, shading reduction factors in the PHPP are determined by entering the depth and offset of 3 discrete shading types; horizon, overhang and lateral reveal. The shading factors are then approximated by empirically derived algorithms, which have been calibrated against dynamic simulations using Dynbil.

This method has been continuously improved for over 20 years and proven to be reliable. However, using these 6 dimensions to describe all shading situations can be time consuming and restrictive in more complex situations.

A new method has been developed for designPH to calculate shading reduction factors by real-time geometric analysis of the model, based on detailed ray-trace detection of shading objects and a corresponding shading mask. This gives more easily and accurate shading factors for complex shading situations and greater sensitivity to certain types of shading objects.

Throughout the development stages we have tested and compared the shading outputs from PHPP, designPH2 and dynamic simulation results (using Dynbil) and have found good consistency and justified differences. Both designPH 2.0 and PHPP are therefore reliable tools for calculating the shading reduction factors in Passive House buildings.

Compatibility

designPH 2.0 is currently compatible with SketchUp 2017, 2018 and 2019 desktop versions.
