Common Mistakes by Singapore Architects

!

Underestimating traffic and MRT noise exposure — Singapore's urban density means most buildings face significant external noise requiring enhanced facade performance

!

Not designing for tropical rain noise impact on lightweight roofs — tropical downpours generate 70-80 dB on metal roofs, requiring acoustic insulation

!

Overlooking the acoustic impact of open-plan tropical design with natural ventilation — open facades conflict with noise control requirements

BCA Green Mark 2021 + SS 553

BCA requires acoustic impact assessment for developments near MRT lines. Green Mark 2021 is mandatory for buildings >5000 m².

Frequently Asked Questions: Singapore Acoustics

Is BCA Green Mark mandatory in Singapore?▾
Yes, BCA Green Mark certification is mandatory for all new buildings with gross floor area exceeding 5,000 m² since 2008. The 2021 version (GM:2021) includes acoustic performance criteria under Indoor Environmental Quality (IEQ-3). All new government buildings must achieve Green Mark Platinum. For smaller buildings, Green Mark is voluntary but incentivised through gross floor area bonuses.
What noise levels does SS 553 require?▾
SS 553:2016 sets maximum permissible noise levels from HVAC systems: NC-35 for general offices, NC-30 for executive offices, NC-25 for conference rooms, NC-40 for retail spaces, and NC-25 for hotel guest rooms. These are measured as the NC rating of the total HVAC system noise at the receiver location and do not include other noise sources.
Do I need an acoustic assessment for projects near MRT?▾
Yes, URA requires a Noise Impact Assessment for all residential and noise-sensitive developments within 100m of MRT lines. The assessment must demonstrate that interior noise levels can meet the NEA guidelines (typically 57 dB LAeq,1hr daytime and 52 dB LAeq,1hr night-time for residential). This often requires enhanced facade design with STC 35-45 depending on proximity.
How does Green Mark 2021 assess acoustic performance?▾
BCA Green Mark 2021 IEQ-3 awards points for acoustic comfort based on: background noise levels meeting SS 553 or ASHRAE criteria, sound insulation between tenancies meeting STC 50+, and reverberation time in common areas meeting recommended values. Enhanced performance (exceeding minimums by 5 dB) earns additional points. Verification through post-occupancy testing is required for higher ratings.
