Building Performance Testing
Independent testing to verify energy performance and building quality
We provide specialist building performance testing for projects targeting high-performance outcomes, including Passivhaus, NatHERS and Green Star.
Our role is focused on independent testing and reporting. Design decisions, compliance assessment or remedial works remain with the project team.
Who This Service Is For
Our service supports homeowners and professionals involved in the design, construction and certification of high-performance buildings:
Homewoners – building or renovating their sustainable or high-performance home
Architects and designers – verify design intent and envelope continuity
Builders and contractors – document construction quality and envelope performance
Passivhaus designers and certifiers – support certification and performance targets
Building certifiers – provide measured data for performance or rating scheme requirements
Core Services
We offer specialised diagnostic testing for key aspects of the building envelope:
Airtightness testing to measure air leakage and provide results that can be referenced against Passivhaus, NatHERS or project-specific standards
Thermal imaging to identify insulation gaps, thermal bridges or moisture-related anomalies
Combined for detailed investigation
Where This Applies
High-performance projects
Passivhaus certification (n50 airtightness targets)
Projects requiring energy performance verification or quality assurance
When Testing Is Recommended
Building performance testing is most effective:
During construction – early issue detection and easier rectification
At project completion – to verify compliance
When assessing modifications or renovations on high-performance buildings
What You Receive
Measured performance data
Thermal imaging reports highlighting areas of interest
Clear reporting suitable for project documentation
Observations to support energy performance outcomes and certification purposes
Scope and Limitations
Our testing services are focused on diagnostics and performance verification. They do not include:
Design or construction advice
Remedial or rectification works
Structural assessment
Detailed energy modelling (NatHERS or Green Star calculations are completed by accredited assessors)
