Acoustic Building Requirements in Austria

Austria maintains comprehensive acoustic requirements through the ÖNORM B 8115 series: Part 1 covers fundamentals and assessment, Part 2 addresses sound insulation requirements, and Part 4 covers room acoustics. These standards are incorporated into the building technical regulations (OIB-Richtlinien) of each Bundesland (federal state), making them legally binding. Austria's acoustic engineering tradition is deeply intertwined with its musical heritage — Vienna alone hosts over 15,000 musical events annually, sustaining world-class expertise in performance venue design. The construction sector, valued at approximately €45 billion annually, is characterised by high quality standards and a strong preference for masonry and concrete construction, which generally provides good acoustic performance. Growth drivers include urban densification in Vienna (the fastest-growing major city in the German-speaking world), sustainable building initiatives under the klimaaktiv programme, and education infrastructure investment. Wood construction is gaining importance, with Austria having significant expertise in CLT (Austria is a major manufacturer). ÖGNI (Austrian Green Building Council) certification includes acoustic criteria aligned with DGNB. Challenges include balancing acoustic performance with thermal upgrades in the large stock of Gründerzeit-era buildings, managing the acoustic implications of increasing HVAC complexity in energy-efficient buildings, and ensuring quality in the growing prefabricated timber construction sector. AcousPlan supports Austrian practitioners with ÖNORM B 8115 compliance calculations, room acoustic analysis per Part 4, and integration with OIB guideline documentation.
