PHPP & PASSIVHAUS CONSULTANCY

​

 to architectural practices, governing bodies, developers and private clients through:-

 

  • Design stage PHPP pre- assessment modelling. Ideally executed pre-planning to inform the design process. Refining elements that could facilitate the attainability of Passivhaus, EnerPHit or Low Energy Certification.

  • Final stage PHPP modelling and associated drawings for submission to PI Certifier.

  • Fabric first consultation and advice for  architectural detailing related to Passivhaus matters.

  • On-site consultancy to address technical issues around airtightness, cold bridging, ventilation, water permeability etc. aiding project managers, contractors and tradespersons.

PHPP

 

Definition from Passipedia :-

 

"The Passive House Planning Package (PHPP) contains everything necessary for designing a properly functioning Passive House. The PHPP prepares an energy balance and calculates the annual energy demand of the building based on the user input relating to the building's characteristics.

​

The PHPP forms the basis for quality assurance and certification of a building as a Passive House or an EnerPHit retrofit. 

​

The main results provided by this software programme include:

  • The annual heating demand [kWh/(m²a)] and maximum heating load [W/m²]

  • Summer thermal comfort with active cooling: annual cooling demand [kWh/(m²a)] and maximum cooling load [W/m²]

  • Summer thermal comfort with passive cooling: frequency of overheating events [%]

  • Annual primary energy demand for the whole building [kWh/(m²a)]

​

Among other things, the PHPP deals with the following aspects:

  • Dimensioning of individual components (building component assemblies including U-value calculation, quality of windows, shading, ventilation etc.) and their influence on the energy balance of the building in winter as well as in summer

  • Dimensioning of the heating load and cooling load

  • Dimensioning of the mechanical systems for the entire building: heating, cooling, hot water provision

  • Verification of the energy efficiency of the building concept in its entirety
