Constructing and certifying a passive house requires specialised expertise. Homeowners should seek out the assistance of passive house professionals, designers and builders to ensure compliance with passive house standards. These experts provide guidance on budgeting, material selection and construction techniques. Early involvement helps prevent mistakes and keeps projects aligned with passive house principles and standards. Skilled tradespeople oversee airtight construction, insulation and ventilation to maintain performance, while air tightness testing, including blower door tests, verifies construction quality and identifies areas for improvement.

Certification confirms a building meets passive house standards in line with the chosen authority. Approved certifiers assess energy efficiency, air tightness and indoor comfort in line with passive house standards set out by either the Passive House Institute or Phius.org. Passive Houses connects homeowners with professionals who guide them through documentation, testing and approval processes with local authorities. Understanding certification requirements, timelines, and benchmarks helps builders and homeowners avoid delays and ensures projects achieve the intended performance.
