A clear understanding of the calculations and predictions involved in Passivhaus building relies upon modelling software.

The Passivhaus Planning Package (PHPP) is a design tool produced by the Passivhaus Institute aimed for use by architects, engineers, and building designers. All Passivhaus buildings must be modelled in PHPP. It is crucial to the quality assurance provided by the Standard. PHPP’s level of sophistication enables it to consider a wide range of variable characteristics which affect heat loss, energy use and internal comfort, allowing for a superior fit between predicted energy use and real-world performance. 

DesignPH is a plugin for the 3D design software SketchUp. It enables quick results & preliminary simplified energy balance. PHPP is required to use the visually interactive designPH software. See for full details of the features and software requirements.

EasyPH offers a simplified and streamlined Passivhaus certification for single dwellings.
