PHPP version 6.1 has recently been released by the Passive House Institute with a new feature to determine energy demand in refurbishment projects – developed in the 3ENCULT project.
The PHPP is the standard tool for design and certification of Passive Houses. PHPP version 6.1, newly released by the Passive House Institute, has a new feature developed within the 3ENCULT project. This allows designers to determine energy demand in renovation projects. A dropdown menu in the Verification worksheet offers the options “Passive House” or “EnerPHit” (Energy retrofit with Passive House components) for selection. The energy performance of the building in question is subsequently rated according to the corresponding certification criteria.
Further improvements, useful for refurbishments and new builds alike, include:
- Taking into account the parallel operation of up to 10 different ventilation systems
- Determining design of air flow volumes based on individual rooms
- A more detailed calculation of window thermal bridges
- A data import/export interface
At the core of the package are worksheets for heating energy balances (using annual demand or the monthly method), heat distribution and supply, electricity demand and primary energy demand. Within 3encult, the PHPP will be extended in order to improve the calculation of energy balances for historic buildings.
The new PHPP version is currently available in German only. The new English version will follow in early 2012.
