English Version of PHPP9 Design Software
Darmstadt, Germany. The tried and tested PHPP tool for designing energy efficient, sustainable buildings is available in a brand-new version. This upgrade not only allows reliable calculation of the energy demand in accordance with internationally applicable criteria, it also takes into account energy generation on or near the building.
Over the past few months a German edition of the PHPP 9 has already been successfully used in practice; the English version was presented at the NAPHN15 North American Passive House conference on 1 – 2 October in Vancouver and at the UK Passivhaus Conference taking place on 20 October in London.
“With this upgrade, PHPP can be applied on an even larger scale; it allows the designer to compare numerous design or retrofit situations in a comprehensible manner”, says Jan Steiger, who coordinates the development of the tool at the international Passive House Institute. In addition, certification according to the new Passive House classes also begins with the launch of PHPP 9.
In addition to the established Passive House Classic, there are now also the Passive House Plus and the Passive House Premium classes, where energy generation is taken into account based on clearly defined criteria. The building’s energy demand is determined according to a system based on Primary Energy Renewable (PER).

PHPP 9 – the design tool for energy efficient, sustainable buildings and retrofits.
The new features in the PHPP also include innovative options, for example for heat recovery from shower water or for profitability calculations. The practical use of the tool is facilitated by means of automatic verification and plausibility checks.
Different options for a particular measure can now be entered in one PHPP file and tested with reference to their respective effects. In this way it is possible to depict improvement in efficiency due to individual refurbishment steps.
In addition, the EnerPHit criteria for retrofits can now be applied internationally without restriction, with building component requirements suiting relevant climate zones.
The NAPHN conference in Vancouver, Canada brings together key stakeholders of the Passive House sector in North America as well as from other parts of the world. Top-class speakers presented the latest projects and concepts in their lectures; Dr Witta Ebel and Adrian Muskatewitz of the international Passive House Institute were also among the speakers.
In the run-up to the conference, a series of workshops were offered in Vancouver on various topics including the PHPP 9 and the supplementary 3D tool designPH.
For many years, the PHPP (Passive House Planning Package) which is continuously developed by the Passive House Institute has provided architects, designers and energy consultants the possibility of optimizing a building design on the basis of clear figures.
The Excel-based calculation tool serves not only as a reliable planning aid but also as verification of compliance with the internationally applicable criteria of the Passive House Standard and the EnerPHit Standard for retrofits. Due to its high accuracy in energy balance calculation, the PHPP is perfectly suitable for planning Nearly Zero-Energy Buildings (NZEB) as stipulated in the EU’s Energy Performance of Buildings Directive. The user handbook not only offers a description on how to use the tool, but also acts as a guide to successfully design working Passive House buildings. The PHPP is available in 20 languages in total.
The latest version will also be translated into other languages. Both PHPP and design PH can be purchased all over the world from accredited partners of the Passive House Institute.
