What’s Required
Austria’s building energy performance requirements are implemented through provincial rules that reference harmonised guidance, including OIB Guideline 6, which is repeatedly updated to reflect EU building efficiency requirements.
Key requirements include:
Minimum energy performance criteria for new buildings and major renovations.
Compliance evidence through planning documentation and performance calculations.
Integration of building envelope, heating/cooling efficiency, and system-level performance requirements.
Important Deadlines
Event-based: triggered by building permits and major renovation permits.
Requirements update cycles follow EU directive evolution and national harmonisation updates.
Current Status
OIB Guideline 6 is a central technical reference used in Austrian building compliance discussions, with ongoing evolution tied to EU building law.
Penalties for Non-Compliance
Permit refusal.
Orders to revise plans or retrofit to a compliant specification.
Examples of Known Violations
