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!

Passive House Institute, Jan Steiger, 1 June 2015
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)]
-
Passive House Institute, Jan Steiger, 1 June 2015
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 !
Monitoring projects:
Comparison ofcalculated demand andmeasured consumption

The NZEB Challange
Enable sustainable energy supply
Apply highest efficiency and couple itWith renewable energy production
The new Passive House Classes:
Classic - Plus - Premium
-
Passive House Institute, Jan Steiger, 1 June 2015
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
-
Passive House Institute, Jan Steiger, 1 June 2015
Primary Energy Renewable (PER)

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.
