The PHPP is a software design tool developed by the PHI (Passivhaus Institut) for development of Passivhaus and verification of Passivhaus standard.
it is encoded as an MS Excel spreadsheet and it can be used by designers to evaluate design solutions immediately without the need to wait for dynamic simulations to run.
The PHPP was originally developed for central European countries and therefore focused mainly on heating demand and winter comfort
Within the Passive-On project, PHI extended the PHPP to warmer climates and included some essential passive cooling strategies (such as natural and night ventilation, thermal mass, ground coupling, summer shading).


The PHPP was validated by:
– Detailed thermal simulation (namely Dynbil)
– Measurements of numerous buildings (namely the 220 CEPHEUS projects)

The PHPP 2007 software proposed on the Passive on project is a demo version with reduced functionality and  is available on the Passive-On CD and for download from the Passive-On WEB site.
This version was used to test proposed Passivhaus for Southern Europe in the Passive On project (see output Passive on_3 part 2).

The PHPP allows:
• Heating demand calculation based on EN 13790 (monthly energy balance) with support in calculation of:
– U-values, including windows
– ventilation and infiltration losses
– passive solar gains, including shading
– internal gains
• Calculation tools for:
– household and auxiliary electricity demand
– primary energy demand
– peak heating load
– summer comfort (overheating fraction)

The new calculations introduced into PHPP 2007, developed within the context of Passive-On are:
• Specific space heat demand for achieving winter comfort (conventional resultant interior temperature: 20 ºC)
• Peak Heating load
• Specific useful cooling energy demand for achieving summer comfort (conventional resultant interior temperature overheating limit: 26 ºC)
• Daily average peak cooling load for low-cooling-energy buildings (not suitable for high diurnal variations of thermal loads)
• Frequency of overheating in case only passive solutions are used
• Primary energy consumption (may consider contribution from renewable sources such as thermal solar systems of PV systems)
• Specific cooling passive strategies implemented:
– Summer shading
– Natural and Night ventilation
– Thermal Mass
– Ground Coupling
