The practitioner membership for
confident PHPP modelling.
Use PHPP accurately on any project — new build, design analysis, or retrofit assessment. Monthly Q&A, model reviews, ANZ-specific calibration, and a permanent library of timestamped discussions, all in one place.
Ten modules. One tool. Every project type.
PHPP School is a modelling course — not a Passive House certification course. The curriculum covers accurate use of the PHPP tool across new builds, design analysis, retrofit assessments, and performance comparisons. Certification is one application. Confident modelling is the goal.
Start with the course. Stay for the support.
The ongoing membership is where the real value is — for any practitioner running PHPP on live projects.

Every model review checks your PHPP against all ten error categories above — TFA methodology, window entry, shading assumptions, MVHR completeness, lambda values, output interpretation, and ANZ-specific cooling and ventilation calibrations. The written report is structured under those headings so you know exactly what was checked and what needs addressing.
PHPP School reviews are independent quality checks on your modelling — they are not certification assessments, pre-certification approvals, or guarantees of any outcome. Your certifier reviews your project independently and always has the final word. What a PHPP School review does is help you find and fix modelling errors before they cost time in the certification process — or on any project where PHPP output is informing design decisions.
Reviews are useful well beyond certification work. If you're using PHPP to inform a heating and cooling strategy, assess design options, or advise a client on thermal performance — getting a second set of expert eyes on the model is valuable regardless of whether the project is going for certification.
Built for NZ and Australian conditions.
Two modules address issues that only surface on NZ and Australian projects — taught from direct local experience. They apply regardless of whether the project is targeting certification.
PHPP models cooling as a single zone with continuous 24-hour operation and high thermal mass assumptions. NZ and Australian residential construction — lightweight timber frames, intermittent heat pump use — behaves differently. Practitioners who apply the PHPP cooling figure directly to HVAC sizing consistently undersize equipment. This module covers how to read and adjust the output correctly for local construction types.
- →Why PHPP cooling output is an average, not a peak — and what that means for HVAC sizing in NZ/AU
- →Adjusting internal gains, setpoints, and weather assumptions for local conditions
- →When to use supplementary tools alongside PHPP for cooling-dominated climates
PHPP's default ventilation assumptions reflect German occupancy standards and regulatory requirements. NZ and Australian ventilation codes imply different minimum flow rates. Models built on PHPP defaults without local adjustment consistently show a gap at commissioning — when measured flows don't match modelled assumptions. This module documents the correct settings for NZ and AU projects.
- →NZ ventilation requirements and how they translate into PHPP inputs
- →Australian equivalents — jurisdiction-by-jurisdiction summary
- →What to check before commissioning to avoid flow rate surprises
PHPP pre-submission checklist.
A one-page checklist covering the ten most common PHPP errors. Use it before every submission. Free to download — no sign-up required.
Group sessions. Recorded. Every discussion timestamped and searchable.
The monthly Q&A runs as a group session — not individual calls. That's by design: the range of questions is more useful to everyone, and the full library of past sessions stays on the platform permanently.
- →10 min: One teaching point — a PHPP tip, common error, or version change
- →50 min: Open Q&A — submit questions in advance or raise live
- →First Thursday of each month, 12:00 NZST
- →Can't attend live? Every session is recorded — watch at any time
- →Every Q&A recorded and added to the member library within 48 hours
- →Discussions timestamped — jump directly to the question you need
- →Full archive available from day one of your membership
- →Searchable by topic — TFA, windows, shading, MVHR, cooling load, and more
- →Post questions any time — responses within 2 business days
- →All discussions timestamped and permanently archived on the platform
- →Pinned threads for the ten most common error categories
- →Members answer each other — the archive compounds in value over time
