Frequently Asked Questions: Singapore Acoustics

Is Green Mark acoustic assessment mandatory in Singapore?▾
Yes, BCA Green Mark certification is mandatory for new buildings with GFA >5,000 m². Green Mark 2021 IEQ-3 includes acoustic performance criteria covering HVAC noise (per SS 553), inter-tenancy sound insulation, and reverberation time for common spaces. All government buildings must achieve Green Mark Platinum, which requires enhanced acoustic performance with post-occupancy verification.
What acoustic challenges are specific to Singapore?▾
Singapore’s urban density creates unique acoustic challenges: proximity to MRT lines (many buildings are within 50m of rail corridors), high traffic noise on expressways, tropical rain noise impact on lightweight roofs and facades, competing requirements between natural ventilation (encouraged by Green Mark) and noise control, and construction noise from ongoing nationwide development.
Do HDB flats have acoustic requirements?▾
HDB (Housing Development Board) sets acoustic performance requirements for public housing. Current standards require STC 45+ between dwelling units, background noise levels meeting SS 553 criteria, and enhanced facade performance for flats near expressways or MRT lines. The Prefabricated Pre-finished Volumetric Construction (PPVC) method used in new HDB projects has specific acoustic detailing requirements.
