What You'll Learn
Passivhaus Standards and the Tester's RoleUnderstand the three PHI building standards, PHI Criteria 10c as the governing document, and exactly where the ATTMA PH+ tester fits within the certification process.
Volume & Surface Area CalculationsCalculate net internal air volume (Vn50) correctly from drawings and on-site measurements, apply the full TSL4 include/exclude rules, and handle discrepancies with the designer's PHPP.
Building Preparation, Testing, Reporting & CertificationPrepare buildings correctly for PH testing, conduct ISO 9972 Method 1 tests to ATTMA TSL4 standard, interpret and report results, and complete certification lodgement professionally.
Who This Course Is For
Existing ATTMA L1 testers wanting to move toward PH+ work
Existing ATTMA L2 testers expanding into Passivhaus, EnerPHit, and PHI Low Energy projects

Testers who need stronger understanding of PHI criteria, reference volume rules, and reporting
Course Modules
Module 1 — Passivhaus Standards & the Tester's Context (~35 min)
The three PHI building standards (Classic, EnerPHit, Low Energy), PHI Criteria 10c as the current governing document, the Passivhaus professional ecosystem, independence requirements, and how PH+ testing differs from standard L1/L2 work.
Module 2 — Volume & Surface Area Calculations (~40 min)
Net internal air volume (Vn50) as the reference, the complete TSL4 include/exclude rules table, calculating volume from drawings (Acrobat/Excel method), on-site verification, and how to handle discrepancies with the designer's PHPP.
Module 3 — Building Preparation for PH Testing (~35 min)
The golden rule, MVHR sealing locations and the exterior duct diagnostic, heat pumps and PTHPs, fireplaces, temporary sealing rules, and a full building preparation checklist for use on site.
Module 4 — Conducting the Test & Interpreting Results (~45 min)
ISO 9972 Method 1 in practice, ATTMA TSL4 requirements, running positive and negative tests in TECTITE, windy day strategies, the 10% divergence rule, rounding rules and pass/fail logic, and multi-fan testing for large buildings.
Module 5 — Reporting, Lodgement & Certification (~35 min)
What the ATTMA TSL4 test report must contain, the volume calculation document, the Low Energy Certificate, lodgement process, professional scenarios (narrow pass/fail), record keeping, and independence obligations.
Assessment & Certification
This course includes module knowledge checks throughout, plus a final assessment to confirm your competency across all five modules. On successful completion, you will receive a Certificate of Completion from BEO Buildingscience. This certificate demonstrates your understanding of ATTMA PH+ testing requirements and prepares you to apply for your ATTMA PH+ accreditation.
Frequently Asked Questions
-
Yes. This course is designed specifically for qualified ATTMA L1 and L2 airtightness testers who want to move into Passivhaus and low energy building certification work. You should be comfortable conducting standard blowerdoor tests before starting.
-
You will need your existing blowerdoor equipment (fan, pressure gauge, envelope frame) and TECTITE Express software. For volume calculations, access to PDF drawings and Excel is required. All course materials, worked examples, and reference documents are provided within the course.
-
The course is fully online and self-paced. Total content time is approximately 3 hours across 5 modules. You can work through it at your own pace and revisit any module at any time. Access is retained after completion.
-
Completing this course provides you with the knowledge and documented training required as part of the ATTMA PH+ accreditation pathway. You will still need to register with ATTMA and satisfy their accreditation requirements, which include supervised site experience and formal assessment.
-
Yes. The course is based on PHI Criteria 10c and ATTMA TSL4, which are internationally recognised standards. It is directly relevant to testers working on Passivhaus and PHI Low Energy projects in Australia, the UK, and other markets where PHI certification is used.
