Verification
Independent quality assurance to ensure your building meets the rigorous performance standards required for international passive house certification.
A practical answer
What is Passive House verification?
Passive House verification is the evidence-based review of whether a project meets the relevant performance requirements and documentation expectations for its chosen pathway. It connects design modelling, construction information, testing, and project records.
Clear answers
Questions about Passive House verification?
When should verification planning begin?
Verification planning should begin early enough for the project team to understand performance requirements, documentation needs, modelling inputs, and testing responsibilities.
What information is needed for verification?
The requirements vary by project, but may include design and construction information, modelling, product and system data, testing results, and supporting project records.
How does airtightness testing fit into verification?
Airtightness testing can provide measured evidence about envelope performance. It is one part of the broader evidence and review process.
Can AllClimate discuss verification support for a project?
Yes. Use the Contact page to share the project stage, location, design information, and the type of verification support you are exploring.
