PHPP Illustrated by Sarah Lewis :

Step-by-Step approach how to enter building data into PHPP 8

General recommendations for Passive House design

Released by RIBA Publishing

It`s easy!


PHPP 9: Calculation results

- Annual heating demand [kWh/(ma)] and maximal heating load [W/m]

- In case of active cooling: annual cooling demand [kWh/(ma)] and maximal cooling load [W/m]

- Comfort in summer through passive cooling: Frequency of overheating [%]

- Annual Primary Energy Renewable and Primary energy demands for all energy services in the entire building [kWh/(ma)]

- Estimation of annual renewable energy gains [kWh/(ma)]


PHPP: Validated precision

- Very good compliance of the energy demand calculated with PHPP andthe measured consumption or load detected in monitoring projects

- Compliance of the calculated heating load- The more efficient the building, the lower the deviations- No performance gaps when planning with PHPP - PHPP is the ideal design tool for efficient buildings like - Passive Houses, NZEBs or other efficiency projects !

The energy balance and planning tool for efficient buildings and retrofits such as Passive House buildings and NZEBs

- Sustainability evaluation after PER factors- Verification of Passive House classes - International climate zones and EnerPHit criteria- Input for calculation of variants - Cost-efficiency comparison for planning variants- Systematic input assistance and error messages- Extension of calculation fo heat losses for DHW - Comprehensive component categories included- Extension of PHPP additional tools

Passive House Institute


The NZEB Challange

Enable sustainable energy supply

Apply highest efficiency and couple itWith renewable energy production

The new Passive House Classes:

Classic - Plus - Premium


Evaluation of energy generation

Do not allocate energy generation directly with energy demand!- The plus energy approach leads to erroneous optimisation.- Multi-storey buildings are systematically penalised, since they have less roof or facade areas in comparison to useful area availablePHI evaluation proposal:- Energy generation will be drawn from planned ground area of heated space.- New off-site Incorporate systems


Primary Energy Renewable (PER)

Renewable energygains

Energy demand depending on use

Direct use of energy or Energy storage

Passive House Institute 2014

Sustainability evaluation based on a future scenario in which only renewable energies are in operation.


Even a Passive House cannot completely be supplied with PV energy in winter! The more storeys, the harder it gets!
