PHPP 10 has landed!

The latest iteration of the Passivhaus Planning Package (PHPP) software is now available in English. We look at what's new, and how to get hold of it.

Essential Passivhaus design tool

PHPP10 coverThe Passivhaus Planning Package (PHPP) is an essential tool for designing and modelling Passivhaus buildings. All certified 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. 

PHPP 10 is the latest version of the software and includes numerous new features in response to requests and feedback from Passivhaus practitioners.

New features

The Passivhaus Institute has created a document giving an overview of the key changes. We summarise the key new features below:


Risk assessment to ensure summer comfort

Building on PHT's own stress tests for overheating, PHPP10 now supplements the calculation of the frequency of overheating with a stress test for summer comfort. Besides a set of pre-defined risk parameters, the manual input of different user behaviours is also possible. 

If you are still working with PHPP 9 you can continue to use the Passivhaus Trust's avoiding overheating stress test guidance to supplement the PHPP, but once you start using PHPP10 it it is fully integrated


Comparison with monitoring data

In the worksheet MONI, the PHPP calculation can be adjusted to actual conditions such as weather data or room temperatures, in a given period in order to make the actual consumption values comparable with the calculation results in the PHPP. This means that several results in PHPP, such as heating demand, energy demand for domestic hot water or electricity, can be compared to monitoring results


Room Data tool and Record tool

A new external tool, the Room Data tool, allows the systematic determination of essential input variables for the PHPP, which is especially helpful for complex projects. 


Variant calculation with data entry for renewables of PV or solar thermal

This worksheet was supplemented with input variables for renewable energy generation from solar thermal systems and photovoltaics. This makes it possible to include renewable energy sources into a EnerPHit Retrofit Plan,  and so helps demonstrate EnerPHit classes Plus or Premium for staged retrofits.


Project overview

The project overview section has been redesigned and includes new result charts, and a column to export data, which enables the transfer of relevant information into the Passivhaus project database.



New component categories for heat pumps and combined ventilation and split units

New certified components categories have been added to PHPP. In addition to heat pumps, you can now enter combined ventilation and split units.

 


Data entry of window systems and curtain wall façades

The input of transparent components has been extended and now also allows the input of windows with multiple panes or curtain wall façades in a single row.

We are delighted that the Trust’s overheating stress tests have been incorporated into the latest version of PHPP10. We look forward to disseminating the latest features at the 2022 UK Passivhaus Conference, including some useful new worksheets and handy tools."

Updated criteria

Passivhaus Institute Criteria May 2022Coinciding with the newly launched PHPP 10 is revised Passivhaus building criteria and updated requirements for certification. Among other things, the calculation of the limit values now takes into account the boundary conditions of a specific building. This applies to the primary energy demand of densely occupied residential and office buildings and the requirements for comfort and mould prevention. The requirements for building cooling have also been revised.
